Must-know sheet

AP® Business with Personal Finance must-know sheet

The formulas, frameworks and key terms to know cold for the first AP Business with Personal Finance exam (May 4, 2027), checked against the fall 2026 course framework. College Board doesn't list a formula sheet for this exam and you get only a four-function calculator, so learn these formulas and practice the math by hand. Example numbers are made up for practice unless a source and date are given.

The exam and the free-response questions

Units 1, 2, 3, 4

Section I: 60 multiple-choice questions, 70 minutes, 60% of your score: Questions come in sets of 3 or 4 that share a source, such as a short case, a chart, a financial statement or a job description, and each has four choices. About 12–15 of them (20–25%) are on personal finance.
Unit weights (multiple choice): Unit 1: 20–30%. Unit 2: 20–30%. Unit 3 (both parts together): 25–35%. Unit 4: 15–20%. Unit 5 isn't on the exam; the class covers it through the Financial Advisor Project.
Skill weights (multiple choice): Concept Application 45–55%, Decision Making 25–35%, Entrepreneurship 5–15% and Communication 5–15%. So most questions ask you to apply an idea to a case or read data, not just define a term.
Section II: 4 free-response questions, 90 minutes, 40% of your score: Question 1, the Business Canvas Project (10 points, 15%), has its own 25 minutes. Questions 2–4 share 65 minutes: Personal Finance (3 points, 5%), Business Concept Application (3 points, 5%) and Business Decision (8 points, 15%; plan about 40 minutes, including 15 minutes of reading).
Calculator: four-function only, and no formula sheet: Use a basic four-function calculator or the Desmos four-function calculator built into Bluebook; scientific and graphing calculators aren't allowed. The whole exam is digital, and College Board doesn't list a formula sheet, so learn the formulas below.
Task verbs: Identify: name it, no explanation needed. Describe: give its key features. Explain: say how or why, with reasoning or evidence. Compare: give similarities or differences. Recommend: choose a course of action and back it up. Pitch: say what the product is, who it's for, what problem it solves and how it creates value.
Q1 pitch: four parts: Briefly describe your product, give your target customer profile with at least one specific demographic or psychographic detail, name the problem, need or want it addresses, and explain how it creates value for that customer. Know your own project's details and numbers before exam day.
Q1 hypothesis test: four parts: State the hypothesis as a testable assumption (for example, "If I charge $12, at least 30 classmates will buy one a month"), name the research method (survey, A/B test, interview and so on), give the specific evidence with numbers, and explain the decision that evidence led to.
Q1 challenge to viability: When asked whether a common challenge, such as getting outside money, threatens your idea, take a side and explain why with evidence from your project, like your startup costs compared with the money you have. A claim with no reasons or evidence earns nothing.
Q1 also asks short concept questions: Some parts of Q1 test a general idea rather than your project, such as one reason a business would use cost-based pricing, or one purpose of outside financial capital (paying startup costs, buying equipment, growing, or covering day-to-day bills). Describe the purpose itself; just naming a source, like a bank loan, doesn't earn the point.
Q2 Personal Finance (3 points): Read the data correctly (for example, total assets compared with total liabilities), describe one challenge or opportunity the person faces, and explain how one specific action would help them reach a goal. Use the scenario's numbers in your answer. Scenarios can include things like credit card debt with a high APR or an employer that matches retirement savings, which is extra money the person gets only by saving.
Q3 Business Concept Application (3 points): Name the research method the business used (say whether it's primary or secondary and what exactly they did), state one finding with numbers from the chart, and explain how the business could use that finding to reach a goal such as gaining market share.
Q4 Business Decision (8 points): First describe an internal, market or external factor and explain how it creates an opportunity or a problem. Then compare the two options on the criteria asked for (such as ROI, another financial one and a nonfinancial one), with evidence for both options each time. Finally, recommend one option and support it with three criteria and evidence from the case.
Internal, market and external factors: Internal factors are inside the business: its people, money, capacity and core competencies. Market factors come from customers, competitors and suppliers, like rising demand or a rival closing. External factors are the wider PESTEL forces, like the economy, laws and community pressure. You don't have to label which kind a factor is; the point comes from describing a factor that's actually in the case, in enough detail.
There's no single right recommendation: In Q4 either option can earn full credit. Points come from choosing clearly, using the case's numbers and facts, and explaining why each criterion favors your choice.

Formulas and worked examples

Units 2, 3, 4

Percent change = (new − old) ÷ old × 100: Use it for any change over time: revenue, costs, profit, a margin or a price. Example: revenue rises from $400,000 to $460,000, so (460,000 − 400,000) ÷ 400,000 × 100 = a 15% increase. Always divide by the starting (old) value. Careful with margins: a margin that goes from 10% to 12% rose 2 percentage points, which is a 20% increase.
Profit margin = profit ÷ revenue × 100: Gross profit margin = gross profit ÷ revenue; operating profit margin = operating profit ÷ revenue; net profit margin = net profit ÷ revenue. Always divide by revenue, never by costs.
Per-unit profit = price − per-unit cost: Per-unit cost = total cost ÷ number of units. A product only makes a profit if its price is above its per-unit cost. Example: price $25 and per-unit cost $18 give a per-unit profit of $7.
Break-even point (units) = fixed costs ÷ (price − variable cost per unit): Break-even is where sales cover all costs for the period, so profit is zero. Example: fixed costs of $6,000 a month, price $25, variable cost $13 per unit: 6,000 ÷ (25 − 13) = 500 units a month. Each unit sold beyond 500 adds $12 of profit. The course describes break-even in words; this is the standard way to find it.
Return on investment (ROI) = added profit ÷ cost of the investment × 100: Use it to compare options in a business decision. Example: a $200,000 machine that adds $30,000 of profit a year has an ROI of 30,000 ÷ 200,000 = 15% a year. A higher ROI wins on this criterion, but it's only one criterion.
Annual rate of return = (income + capital gain) ÷ price paid × 100: Income means interest or dividends; a capital gain means selling for more than you paid. Example: buy a share for $50, collect $2 in dividends and sell a year later for $56: (2 + 6) ÷ 50 = 16%.
Customer acquisition cost (CAC) = marketing, advertising and sales costs ÷ customers gained: Example: spending $12,000 to win 400 new customers is $30 per customer. Lower is better, and it's worth comparing with a customer's lifetime value (what they'll spend over time).
Market share = the business's sales ÷ total sales in the market × 100: Example: $3 million of sales in a $20 million market is a 15% share. It can be measured by revenue or by units, so check which one a chart uses.
Net worth = total assets − total liabilities: For a household, add up savings, investments, property and possessions, then subtract every debt. Example: $42,000 of assets and $30,500 of debts give a net worth of $11,500; if the debts were bigger, net worth would be negative.
Assets = liabilities + owners' equity: The balance sheet equation always balances, so owners' equity = assets − liabilities. Example: $800,000 of assets and $500,000 of liabilities leave $300,000 of owners' equity.
Working capital = current assets − current liabilities: If it's zero or more, current assets can cover the bills due within a year. Example: $150,000 of current assets and $90,000 of current liabilities give $60,000 of working capital.
Simple interest = principal × rate × time: Example: $2,000 saved at an example rate of 4% a year for 3 years earns 2,000 × 0.04 × 3 = $240. Compound interest earns more, because each year's interest also earns interest.

Financial statements

Unit 3

Income statement: profit over a period: It compares revenue with costs over a month, quarter or year to find the net profit or loss. It's also called a profit and loss statement and usually shows several periods side by side.
Revenue − COGS = gross profit: Revenue is money from the business's main activity, like sales. COGS (cost of goods sold) is the direct cost of making the product; for a service it's called cost of sales. Gross profit margin shows how well the business sets prices and controls direct costs.
Gross profit − operating expenses = operating profit: Operating expenses are the indirect costs of running the business: selling costs (ads, salespeople), general and administrative costs (office salaries, office rent, insurance) and research and development. Operating profit margin shows how well it sells and keeps these costs down.
Operating profit − interest = pretax income; pretax income − taxes = net profit: Interest expense is the cost of borrowing through loans or bonds. Net profit is the bottom line: what's left for the owners, and net profit margin measures overall profitability.
Income statement example: Revenue $500,000; COGS $300,000; operating expenses $120,000; interest $10,000; taxes $14,000. Gross profit $200,000 (40% margin), operating profit $80,000 (16%), pretax income $70,000, net profit $56,000 (11.2% margin).
Compare margins with benchmarks: Margins mean most next to the business's past results, its projections and its competitors. A falling gross margin points to pricing or direct costs; a steady gross margin with a falling operating margin points to overhead.
Projected income statements and budgets: A projection estimates future revenue (from pricing plans and market research) and future costs (from production plans and supply costs) to spot funding needs early. A personal budget does the same thing with expected net pay against planned saving, spending and debt payments.
Not on the exam: Adjustments to get net sales, what goes into COGS, nonoperating items other than interest, and anything below the bottom line.
Balance sheet: a snapshot at one moment: It lists what the business owns (assets), what it owes (liabilities) and what it's worth to its owners (owners' equity) on one date, such as the end of a quarter, usually next to the same date in earlier years.
Assets, grouped by liquidity: Liquidity is how easily an asset becomes cash. Current assets: cash, short-term investments, accounts receivable and inventory. Long-term assets: fixed assets like a factory, and long-term investments. Intangible assets: patents, brand names and trademarks.
Liabilities, grouped by when they're due: Current liabilities are due within a year: accounts payable, short-term debt, this year's payments on long-term debt and unpaid expenses. Long-term liabilities, such as mortgages, bank loans and long-term bonds, are due after that.
Receivable vs payable: Accounts receivable is money customers owe the business (an asset). Accounts payable is money the business owes its suppliers (a liability).
Owners' equity and retained earnings: Owners' equity is the business's net worth. It's usually made up of stock plus retained earnings, the past profits the business kept instead of paying out as dividends.
What a balance sheet tells lenders and owners: Whether net worth is positive, whether there's enough working capital for day-to-day bills, and whether debt is in line with similar businesses. A business that can't get enough current assets to keep running may shut down or go bankrupt.
Cash flow statement: cash in and out over a period: It shows how cash inflows and outflows changed the cash balance, so owners, lenders and investors can see whether the business can pay employees, suppliers, lenders and shareholders.
Cash inflows vs outflows: In: customer payments, interest or dividends earned, money from selling assets, and new loans or investment. Out: wages, supplier payments, interest, taxes, buying assets, repaying debt and paying dividends.
Profit isn't the same as cash: A business can show a profit and still run short of cash, for example when customers pay late, and negative cash flow can force it to close. Fixes: raise more money, collect accounts receivable faster, or get better terms from suppliers and lenders.
Three statements, three questions: Income statement: did we make a profit this period? Balance sheet: what do we own and owe right now? Cash flow statement: do we have the cash to pay our bills?
Accounting roles: Accounting records every transaction and prepares the statements. Managerial accountants report to people inside the business, financial accountants report to outsiders like shareholders and lenders, and the finance department turns the numbers into strategy.
Why people cheat in financial reporting: Handling large amounts of a business's cash tempts people to embezzle or misuse funds. A business can also make itself look better or worse than it is to push up its stock price, get better loan terms or pay less tax. Misusing funds, embezzlement, bribery, fraud and tax evasion are illegal in most countries.
GAAP and honest reporting: Corporations that sell shares to the public must follow generally accepted accounting principles (GAAP), reporting good and bad results every quarter or year, and U.S. law requires them to have an independent accounting firm audit their records every year. Codes of ethics and internal controls, like cash-handling rules, help prevent embezzlement, fraud and tax evasion.

Business costs and raising money

Unit 3

Startup costs: One-time costs, such as legal, incorporation and licensing fees and sometimes equipment, plus the first spending on rent, research, marketing, insurance and starting inventory. Those first expenses become ongoing once the business opens.
Direct vs indirect costs: Direct costs are tied to making or delivering the product: COGS for goods, cost of sales for services. Indirect costs, also called operating expenses, are the costs of running the business, such as office and sales salaries, rent, ads, utilities and insurance.
Fixed vs variable costs: Fixed costs stay the same at any level of output, like factory rent. Variable costs rise as output rises, like raw materials. A direct cost can be either one.
Insurance for businesses: Insurance covers big losses a business can't easily absorb, such as an injured worker, an accident or a damaged building. Some coverage is required by law, like workers' compensation; beyond that, how much to buy depends on how much risk the business is willing to carry itself.
Bootstrapping: Paying for a startup with the founder's own savings, personal loans or credit. Founders look for outside money when they can't cover startup and operating costs until the business breaks even.
Why established businesses raise money: To develop new products, replace fixed assets, grow sales, or smooth out cash flow when revenue comes in unevenly but bills keep coming.
Loans vs equity financing: A loan must be repaid with interest, which is a business expense, but the owners keep control. Equity financing sells ownership shares: nothing is repaid, but the new investors get part of the control and future profits.
Who can raise money how: New businesses (usually under two years old) often borrow from friends and family or sell shares. Established businesses with proven revenue can get bank loans. Corporations can also raise money by issuing bonds or stock.
Bonds vs stocks: A bond is a loan from an investor to the business, which pays the bondholder interest. A share of stock is part ownership, which may pay dividends and can rise or fall in price. Both can be resold to other investors in the secondary market.
Dividends and capital gains: A dividend is a shareholder's cut of the profits, though some corporations reinvest profits instead of paying dividends. A capital gain is what you make by selling an asset for more than you paid.
Risk and return: Lenders risk missed payments, and investors risk losing dividends, value or their whole stake if the business fails. The riskier the asset, the higher the return investors expect; risk tolerance is how much risk someone is willing to take.
Business plan and pitch: Lenders and investors usually want a business plan with the value proposition, market research, marketing strategy and financial projections, summed up in a short, persuasive pitch. Evidence of product-market fit, a strong leadership team and a mission that fits the funder's goals all help.
Valuation: An estimate of what a business, and so each ownership share, is worth, based on its financial reports, projections and industry data. It also helps lenders judge whether the business can repay a loan.

Saving, borrowing and credit

Unit 3

Why people save: For big purchases like a car, a home or college, for emergencies like losing a job or getting sick, and for income in retirement. Savings is an asset and can earn interest.
What makes saving hard: Uneven income, bills bigger than income, wanting things now, impulse buying and lifestyle inflation (spending more as you earn more). Automatic savings plans and tax-advantaged retirement and health savings accounts make it easier.
Outside forces on saving: A weak economy can cut income, and a strong one can raise the cost of living. Inflation, rising prices, shrinks what saved money can buy. Tax breaks encourage saving, and government regulators oversee banks and credit unions.
Savings account: Federally insured, usually pays some interest and lets you reach your money easily. Minimum deposits, rates and fees differ from one bank or credit union to another.
Money market account: Federally insured and much like a savings account, but it may need a bigger deposit and charge higher fees in return for more interest and easy access to cash.
Certificate of deposit (CD): Federally insured and usually pays more than a savings or money market account, but your money is locked up for a set term, usually one month to five years. It usually needs a bigger deposit but has no monthly fee.
Checking account: Federally insured and built for everyday spending: deposits, withdrawals, debit card purchases and payments. It pays little or no interest and may charge monthly or overdraft fees.
Payment apps and crypto accounts: Usually not federally insured and usually pay no interest, unless the account is offered by an insured bank or credit union.
Federal deposit insurance: $250,000: The FDIC (banks) and NCUA (credit unions) insure deposits up to $250,000 per depositor, per insured institution, for each ownership category, so insured money isn't lost if the institution fails. Checked on fdic.gov and ncua.gov on 5 Oct 2026.
Choosing where to save: Weigh the interest rate, fees, minimum deposit, risk, access, location, convenience and reputation, along with your goal and time frame. Higher interest usually comes with a trade-off, like a bigger minimum balance or less access to the money.
Why people borrow: To buy something that costs more than their income and savings, like a car, a house or college, to cover an emergency, to keep their savings, or for convenience. A loan is a liability that must be repaid with interest.
Secured vs unsecured loans: A secured loan is backed by collateral, such as the car or house it pays for, which the lender can take if the loan isn't repaid, so the rate is usually lower. An unsecured loan, like most credit card debt, has no collateral and usually a higher rate.
Who lends: Banks and credit unions lend out the money people deposit. Credit card companies, stores and mortgage lenders lend too, and so do alternative financial services, like payday loans, check cashing and instant tax refunds, which usually charge much more.
Bigger loans and higher rates mean bigger payments: Example: a $20,000 car loan repaid over 60 months costs about $386.66 a month and about $3,200 in total interest at an example rate of 6% a year, but about $415.17 a month and about $4,910 in interest at 9%. Big payments leave less income to save or spend.
APR (annual percentage rate): The yearly cost of borrowing as a percentage, which lets you compare loans and credit cards from different lenders. A credit card's monthly interest is roughly balance × APR ÷ 12. Example: a $2,800 balance at an example APR of 23% adds about 2,800 × 0.23 ÷ 12 ≈ $53.67 of interest a month if it isn't paid off.
Default and creditworthiness: Defaulting means not repaying a loan. To judge creditworthiness, lenders look at income, savings, existing debt and your credit report, and they charge riskier borrowers higher rates.
Credit report and credit score: Credit bureaus collect your history with lenders into a credit report, which includes a credit score. Lenders, landlords, employers, insurers and government agencies may check it.
Raising a credit score: Pay bills on time, pay down existing debt and use credit cards less.
Managing debt: Keep a strong credit score, compare offers from several lenders, make a down payment on big purchases, and pay off high-interest debt such as credit cards as fast as possible.
Consumer protection and bankruptcy: Laws require lenders to state credit terms clearly, limit how debts are collected and ban discriminatory lending. People with unmanageable debt can get debt-management help, and bankruptcy is a legal process that wipes out some debts and sets up repayment of others.

Businesses, markets and PESTEL

Unit 1

Business: Any organization that makes and delivers goods or services, of any size, in person or online.
Customer vs consumer: The customer is whoever buys the product; the consumer is whoever uses it. A parent buying a toy for a child is the customer, and the child is the consumer.
Problem-solution fit: A business spots customers' problems, needs and wants (a market opportunity) and makes a product that addresses them. No business can serve everyone, so it chooses which problems and customers to focus on.
Value creation vs value capture: A business creates value when its product solves a customer's problem, need or want. It captures value when it can charge more than the product cost to make.
Market and market price: A market is any place, physical or online, where sellers and buyers meet. Sellers push for higher prices and buyers for lower ones, which in a competitive market settles on a market price. Drawing supply and demand graphs isn't on this exam.
Competitive advantage: The ability to outperform rivals in the same market, which wins market share and can raise profits. How competitive a market is decides which strategy a business uses.
Three ways to compete: Low price, by producing as efficiently as possible (common for commodities like crops). A better or different product, through quality, features, service, price or marketing. Or barriers to entry that keep new rivals out.
Barriers to entry: Obstacles that make it hard for new firms to compete: patents and other intellectual property, regulations, limited access to suppliers, high startup costs, and low prices only a large-scale business can match.
Monopoly: A market with only one seller of a unique product. A monopoly works to keep its barriers to entry high.
P: political factors: Government policies and stability: trade policy, taxes, subsidies, mandates and bans. Subsidies and mandates support some activities, while bans and taxes can limit them.
E: economic factors: The state of the economy: stability, household income, inflation, unemployment and interest rates. Most businesses do better in a strong economy, but some thrive in a weak one.
S: social factors: Trends in society and culture: demographics, cultural norms, lifestyle trends and population growth. These shape what consumers need and want.
T: technological factors: The technology available: internet access, automation and how fast innovation is happening. Production, distribution and communication with customers all depend on it.
E: environmental factors: Physical conditions: geography, climate, natural disasters, access to resources, waste rules and customers' environmental views.
L: legal factors: Specific laws and rules: employment, consumer protection, health and safety, environmental, intellectual property and antitrust laws. They affect operating costs and what's allowed at all.
Using PESTEL: Name the factors that matter for a specific idea and judge whether each makes the market more attractive or riskier. A business enters where the factors fit its model, and changes in the factors can shift which businesses survive and which jobs exist.

New ideas, vision and ethics

Unit 1

Entrepreneur: Someone who starts a new business and takes on its risks and possible rewards. New products are risky because they cost money, materials and people with no guarantee of enough revenue.
Why take the risk: Possible future profits, the reward of solving a real problem for people, or the chance to turn a passion into work.
Where ideas come from: Observing, interviewing and surveying potential customers, researching markets and technology to find gaps, and experimenting to build new capabilities.
Design thinking, step by step: 1) Observe, interview or survey customers to validate a problem. 2) Develop a solution by brainstorming, sketching and prototyping. 3) Get feedback on a minimum viable product from potential customers.
Validation: Gathering evidence that a problem really exists, can be clearly defined and affects many potential customers, and later, that customers want the proposed solution.
Minimum viable product (MVP): The simplest version of a product idea, with only its core features, used to get feedback before spending much money. It doesn't have to work yet: a drawing, a written description or a rough model can count.
Core values vs core competencies: Core values are the beliefs that guide actions, like transparency or reliability. Core competencies are the skills and strengths that help beat rivals, like innovation or efficiency. Both steer which opportunities a business, or a person choosing a career, goes after.
Vision statement vs mission statement: A vision statement briefly sums up a business's core values and hopes. A mission statement says what the business does and how it will reach its long-term goals.
Business, social enterprise or nonprofit: A business aims for profit and long-term success, raising profit by increasing revenue or cutting costs. A social enterprise seeks profit plus a social goal. A nonprofit serves the public good, must put any surplus back into the organization and often relies on grants and donations.
Unethical behavior: Falsifying or hiding information, misusing company property or harming employees or customers. It can happen at any level, often when incentives reward it.
Encouraging ethics: Codes of conduct, ethics training, consequences for wrongdoing and leaders who set a good example. Ethical practices also attract customers and employees and build brand loyalty.
Ethical dilemma: A clash between a core value, like fairness or transparency, and another value or a business goal.
Internal vs external stakeholders: Internal stakeholders are directly involved in the business: owners, managers and employees. External stakeholders aren't, but care about its decisions: customers, government agencies and the community.
How leaders resolve dilemmas: They weigh each response's costs and benefits for every stakeholder group, plus the effect on reputation and culture. Then they pick the option with the most total benefit or least total harm, or the one most consistent with the business's vision and goals.

Business organization and supply chains

Unit 1

Sole proprietorship: One owner keeps all control and profits and plays every role, from CEO to marketer. The owner is personally liable for business debts, and raising money to grow is hard.
Partnership: Two or more owners share control and profits and split roles by strengths. Partners are personally liable for business debts, and funding is limited.
Limited liability company (LLC): The owners keep control and profits but aren't personally liable for business debts. Like the first two types, it has less access to funding than a corporation.
Corporation: Owners give up control to shareholders and an elected board of directors, and the company itself controls profits and is liable for its debts. Corporations usually have the most access to funding and room to grow.
Executives and managers: Executives, like the CEO, run the overall vision, strategy and performance; in a corporation they report to the board and shareholders. Managers lead specialized departments and report to the executives.
Departments: marketing, R&D and operations: Sales and marketing research the market, sell and build customer relationships. Research and development (R&D) creates and improves products and processes. Operations makes the goods or delivers the services.
Departments: accounting, finance and HR: Accounting tracks money in and out and prepares financial statements. Finance raises and manages funds and recommends money strategies. Human resources recruits, trains and evaluates employees.
Outsourcing: Paying another business to do a job when that is cheaper or more efficient, for example when the business lacks the skills or its own labor costs are high.
Artisan vs mass production: Artisan production uses skilled workers and close attention to detail. Mass production uses machines, technology and assembly lines to make large quantities. The choice depends on what customers value (quality, price, customization), core competencies and the competition.
Supply chain for a good: Raw materials and parts go to a factory, where workers and equipment make the finished good, which may go to a warehouse, then a distribution center or store, then the customer. Supply chains can be local, regional or global.
Supply chain for a service: Everything needed to deliver the service, in person or online: the staff, the tools and resources they use, and the system for scheduling and delivering it.
Choosing suppliers: Weigh cost, quality, efficiency, convenience and risk. Natural disasters, political instability, shortages, production errors or a supplier's bad reputation can delay deliveries or raise costs.
Strategy shapes the supply chain: Low price: mass production, cheaper inputs, efficiency and scale (growing so revenue rises faster than costs). High quality: high-quality inputs and methods. Barriers to entry: exclusive deals that stop suppliers or retailers from working with rivals.

Customers and consumer behavior

Unit 2

Marketing: Everything a business does to find customers' problems, needs and wants and to promote, sell and deliver products.
Demographic vs psychographic data: Demographic data are measurable traits like age, sex, race, ethnicity, income and location. Psychographic data describe interests, activities, values and lifestyles.
How businesses collect customer data: Subscriber lists, online accounts, click tracking, apps and social media monitoring, plus surveys and interviews; some buy data from other businesses.
Segments, target customers and customer profiles: Market segmentation groups potential customers by shared traits. Target customers are the segment most likely to buy. A customer profile is a made-up sketch of one typical target customer, and aiming at a target is usually cheaper and more effective than marketing to everyone.
Customer relationships: Personal service, rewards programs and feedback surveys build loyalty. Happy customers refer others, which lowers customer acquisition cost, and buy again, which raises lifetime value.
Risks of customer data: Collecting and storing data can invade privacy, especially when customers don't know, and poor security invites breaches, fraud and identity theft. Businesses weigh the data's benefits against losing customers, breaking their values and damaging their reputation.
Rational vs habitual buying: Big purchases, like a home, get a careful comparison of options, which takes time. Small, routine ones, like a morning coffee, are mostly habit.
What shapes buying decisions: Personal factors (age, income, budget, job, lifestyle), psychological factors (values, perceptions, past experience, motivation), social and cultural factors (peers, family, status, norms, media) and situational factors (store layout, noise, lighting, timing, availability).
Purchasing patterns: A person's usual routine for when, how often and how much they buy, shaped by where they live and work, income, and family and friends. Laws and new technology, like smartphones, change these patterns and can create demand for substitutes.
Cialdini: scarcity: People want things more when they seem rare. Marketers say "limited time only" or "only 2 left".
Cialdini: authority: People follow experts. Marketers use doctors or other experts as spokespeople, or stress their own credentials.
Cialdini: consensus: People follow what others do. Marketers show reviews and say how many people already bought it.
Cialdini: liking: People are swayed by people they like or relate to. Ads feature people who resemble the target customer in age, style or lifestyle.
Cialdini: reciprocity: People feel they owe something back after a gift. Free samples, trials and gifts make buying feel like returning the favor.
Cialdini: consistency: People act in line with their self-image. Marketers pitch a product as what "people like you" buy, such as health-conscious shoppers.
Cialdini: unity: People are swayed by groups they belong to. Marketers build a community, like an exclusive online group or inviting fans to help design products.

Market research and data charts

Unit 2

Market research: Collecting detailed information about markets, products and customers to guide marketing decisions.
Quantitative vs qualitative data: Quantitative data are numbers that answer how many, how much and how often. Qualitative data are words and images that answer why and how.
Desirable, feasible, viable: Before investing heavily, a new product is checked for being desirable (customers want it because it solves their problem), feasible (the business can make it with its resources, technology, skills and time) and viable (it can make a profit).
Secondary research: Using information others have already published, from government, business and academic sources, such as market size, trends, segments and rivals. It's cheaper, so businesses usually start here.
Primary research: Collecting your own new data to test a business hypothesis, with surveys, interviews, focus groups, experiments, observations or A/B tests.
Business hypothesis: An assumption about a customer, product or market that a business tests before acting on it.
Surveys: Best when you need lots of quantitative data that reflects a whole population's views.
Focus groups and interviews: Best for in-depth qualitative answers from a small number of people, with room for follow-up questions.
Experiments and observations: Best when you need to see what customers actually do rather than what they say: in a controlled setting (experiment) or a natural one (observation).
A/B testing: An experiment that shows real customers two versions, like two prices or two web pages, and measures which one gets the better response.
Avoiding skewed data: Use a big enough sample that matches the population, and ask neutral questions. "How much would you pay for this lamp?" is neutral; "Wouldn't you love this amazing lamp?" pushes people toward yes.
Research has limits: Even good research can't always predict how customers will respond, so businesses often have to act on limited, unclear or conflicting data. Existing businesses keep researching to track changing needs and protect market share.
Bar chart: Compares separate values, like sales for several years or revenue for several businesses.
Stacked bar chart: Shows totals and their parts at once, like total yearly sales split into product lines.
Line graph: Shows a trend over time, like the number of customers each year.
Pie chart: Shows parts of a whole, like each company's percentage of market share.

Product and price

Unit 2

Six stages of product development: Ideation (generate ideas), validation (test them with customers), design (prototypes, features and costs), messaging (value proposition and positioning), production (build it and set up the supply chain) and launch (take orders, deliver and market to the target segment).
Product-market fit: Enough customer demand to make a profit. An MVP in the validation stage tests for it.
Value proposition: A statement of who the product is for, what problem or need it addresses and why it beats the alternatives. Positioning shapes how customers see the product compared with rivals.
Branding: Building an identity (a name, symbol, design or idea) that sets a product apart, raises awareness and builds loyalty. Businesses protect a brand with trademarks, and some also sell cheaper generic products to cost-conscious customers.
Product life cycle: Introduction: low sales, so build awareness. Growth: sales climb fast and rivals arrive, so differentiate and advertise. Maturity: sales flatten, so build loyalty, innovate and maybe cut prices. Decline: sales fall, so cut costs, redesign or discontinue.
Price vs per-unit cost: A low price can win market share, but a product only makes a profit if its price is above its per-unit cost.
Value-based pricing: Price set by what customers think the product is worth. Common for highly differentiated or unique products.
Competitive pricing: Price set against rivals' prices. A clearly better product can charge a premium; a similar one prices at or below rivals to gain market share, accepting less profit per unit.
Cost-based pricing: Price = per-unit cost + a chosen profit per unit, ignoring perceived value and rivals' prices. It suits businesses with clear costs they can show customers, like a contractor, and gives a predictable per-unit profit.
Penetration pricing: Start with a low price, possibly below per-unit cost, to pull price-sensitive customers from rivals and grow market share fast, planning to raise it later.
Pricing power: The ability to raise prices without losing market share. It's low in crowded markets with similar products and high with little competition or a very different product.
Price elasticity of demand (concept only): How strongly customers react to price changes. When demand is elastic (very responsive), a price increase can cost so many sales that revenue falls, so pricing power is low. When demand is inelastic (not very responsive), a price cut wins few extra sales, so revenue falls. You won't calculate elasticity on this exam.
Illegal pricing: Price fixing (rivals agreeing on a price) is illegal in the U.S. and many countries. Price gouging (raising prices in a crisis) is illegal in many states. Charging different prices based on race, nationality, sex or another protected status is illegal.

Place and promotion

Unit 2

Place: Where and how customers get a product: in stores, company-owned shops, through memberships or online.
Marketing (distribution) channel: Everyone needed to get a finished product to the final customer, the last stage of the supply chain. Some products, like prescription drugs, must legally go through certain channels.
B2C vs B2B: Business-to-consumer (B2C) channels sell consumer products, through websites and stores. Business-to-business (B2B) channels sell to other businesses, such as through industrial distributors.
Direct channels: Selling straight to customers, with no middlemen, through a company website or company-owned stores. More control over price and the customer experience, but they can cost more to set up, reach fewer people and need sales expertise.
Indirect channels: Selling through intermediaries such as wholesalers and retailers, whose networks and expertise can cut costs and reach more customers. Rivals may already control the shelf space.
Choosing a channel: Compare each channel's costs and potential profit, the customer experience it gives, and whether it reaches the target customers.
Marketing campaign and promotional mix: A campaign is a coordinated push using some or all five promotion tools: media advertising, personal selling, sales promotion, direct marketing and public relations.
Match the tool to the decision: Big, careful purchases may need detailed, personal contact, like a salesperson. Routine purchases can be handled by mass media or direct marketing.
Media advertising: TV, radio, newspapers and billboards: one message to a large audience at the same time.
Personal selling: One-on-one product information or demonstrations, often with a sales pitch: a short presentation of the value proposition to close the sale.
Sales promotion: Discounts and coupons to speed up buying decisions or clear unsold inventory.
Direct marketing: Flyers and brochures that send a targeted message to many potential customers.
Public relations: Press releases and interviews that earn media coverage and build a good public image, rather than pushing one sale.
Digital marketing: Websites, email, social media and apps reach large or narrowly targeted audiences with more personal messages at lower cost. They also collect big data on how customers respond, which TV ads and billboards can't.

Managing people and measuring performance

Unit 4

Management: Planning, organizing, leading and evaluating a business's people, money and physical resources to reach its goals, at every level from executives to supervisors.
Leadership skills: Communicating the vision and mission, building productive teams, settling conflicts and motivating people. Motivated employees work better, stay longer and build stronger relationships with customers and coworkers.
Communication skills: Expressing ideas clearly, persuading, listening with empathy, and understanding and acting on feedback.
Hiring and training: Businesses need employees with a range of skills and backgrounds for different tasks, and may outsource work outside their core competencies. Poorly trained workers can make flawed products or give bad service, so businesses train through college, apprenticeships, on-the-job, online and continuing education.
Types of employment: Full-time, part-time, temporary and contract.
Ways to pay workers: Hourly wage (pay per hour), salary (a fixed yearly amount), commission (a share of sales), piece rate (pay per item made) and profit sharing (a share of profits). The choice depends on the industry, the role, laws like the minimum wage and competition for good workers.
Benefits: Help paying for health insurance, retirement savings plans, health savings plans, disability insurance, tuition reimbursement and paid time off.
Keeping good employees: Raises, promotions, bonuses, independence, flexible hours or locations, recognition and a positive culture. Keeping a good employee usually costs less than hiring and training a new one.
Key performance indicator (KPI): A number a business tracks to measure progress toward its goals and how well its strategy works. Managers pick KPIs that fit their mission, goals, profitability and industry.
Financial KPIs: Revenue, gross profit and gross profit margin, operating profit and operating profit margin, COGS, operating expenses and cash flow.
Marketing and sales KPIs: Customer acquisition cost, customer lifetime value, customer satisfaction ratings, customer retention, total sales and market share.
Operations KPIs: Per-unit cost, delivery cost, order accuracy and the percentage of deliveries on time.
Benchmark: A reference point to compare a KPI against: the business's own past results or an industry standard. A KPI alone says little until it's compared with a benchmark.

Strategy and decision making

Unit 4

Strategy vs tactics: A strategy is a plan to reach a goal, such as competitive advantage, more revenue, lower costs or higher profit. Tactics are the specific actions that carry it out.
Data drives strategy: Businesses track data on finances, customers, competitors and market trends to set a strategy, check whether it's working and adjust it.
PACED decision-making model: Problem: define it. Alternatives: list the options. Criteria: decide what matters. Evaluate: judge each option against the criteria. Decide: choose the best option.
Decision criteria: Financial: ROI, costs, sales and profit. Market: effects on competitiveness. Operational: effects such as supply chain risk. Organizational: effects on employees. Intangible: reputation, mission and core values.
Imperfect decisions: Managers often have to rank conflicting criteria using limited or imperfect data, so even good decisions carry risk.
Strategic frameworks: Tools like Porter's Five Forces and SWOT that check an option's internal and external factors against long-term goals in an organized way.
Porter's Five Forces: the big idea: It judges how attractive and profitable a market is, for decisions like which market to enter or what pricing to use. Strong forces mean a less attractive market with lower likely profits; weak forces mean a more attractive one.
Competitive rivalry: Strong when there are many direct competitors with similar products and little pricing power. It's usually the strongest of the five forces.
Threat of new entrants: Strong when barriers to entry are low, so new businesses can easily move in and take market share.
Threat of substitutes: Substitutes meet the same need without being direct competitors, like video calls instead of business travel. The threat is strong when there are many, especially if they're cheaper, easier to get or better.
Customer power: Buyers' power to push prices down. Strong when there are few customers, each is a big share of sales, acquisition costs are high and switching costs (the money and hassle of changing brands) are low.
Supplier power: Suppliers' power to raise input prices. Strong when there are few suppliers and switching to another is costly.
SWOT: strengths and weaknesses (internal): Strengths: core competencies, brand recognition, intellectual property, quality, ample funds, skilled staff, an efficient supply chain. Weaknesses: missing competencies, low brand recognition, product flaws, limited funds, staffing gaps, poor service, outdated technology, supply chain risks.
SWOT: opportunities and threats (external): Factors outside the business's control. Opportunities: market growth, less competition, new technology, helpful regulation. Threats: rising input costs, natural disasters, harmful regulation, disruptive innovation. PESTEL and the Five Forces help find them.
Using a SWOT: Judge each internal capability against rivals, benchmarks and past results to call it a strength or a weakness. Then build on strengths, fix weaknesses, seize opportunities and respond to threats.

Unit 5: taxes, insurance and investing (not on the AP Exam)

Unit 5

Kinds of taxes: Income tax (withheld from each paycheck, then settled on a yearly return as extra tax owed or a refund), capital gains tax (usually a lower rate than on wages for assets held over a year), payroll taxes, property tax and sales tax (collected by the seller). Self-employed people send in their own income tax.
Progressive income tax: Each higher rate applies only to the income inside its bracket. Example with made-up brackets (10% up to $10,000, 20% from $10,000 to $40,000, 30% above): $50,000 of taxable income owes $1,000 + $6,000 + $3,000 = $10,000, an average rate of 20% even though the top rate is 30%.
Payroll taxes (Social Security and Medicare): For 2026, employees pay 6.2% for Social Security on wages up to $184,500 and 1.45% for Medicare with no cap, and employers pay the same again; self-employed people pay both halves (15.3%) on their self-employment earnings. Source: irs.gov, Topic 751, checked 5 Oct 2026. Example: $1,000 of wages has $62.00 + $14.50 = $76.50 withheld.
Deduction vs credit: A deduction lowers taxable income; a credit cuts the tax itself. Example at a made-up 12% tax rate: a $1,000 deduction saves $120, but a $1,000 credit saves $1,000. Deductions include mortgage interest, retirement contributions, charitable gifts and state and local taxes; credits include child, child care and education credits.
Reading a pay stub: Gross pay − mandatory deductions (income and payroll taxes) − voluntary deductions (health insurance, retirement savings, union dues and so on) = net pay. Pretax deductions come out before tax is figured, so they lower the tax owed.
Gross pay examples: Hourly: $18 an hour × 30 hours = $540 gross for the period. Salary: $52,000 a year paid every two weeks (26 paychecks) = $2,000 gross per paycheck, before any deductions.
Insurable risk: A loss that happens by chance and is predictable enough for an insurer to price. Personal risk: your health. Property risk: damage to your home or car. Liability risk: harm you cause to other people or their property.
Premium, deductible and claim: You pay a premium for coverage, file a claim after a loss and pay the deductible yourself before insurance pays. Choosing a higher deductible or less coverage usually lowers the premium but means more risk you carry yourself.
Types of insurance: Health, auto, homeowner's, renter's and life insurance, plus extended warranties. Most states require auto liability insurance, and mortgage lenders require property insurance.
How much insurance: It depends on legal requirements, risk tolerance and dependents. Safer behavior, like a clean driving record or not smoking, can lower premiums. Lying on a claim or misrepresenting a policy is insurance fraud, a crime.
Protecting against fraud and predatory lending: Compare loan terms from several sources, resist pressure to sign quickly, check with a nonprofit credit counselor, question offers that seem too good, keep personal information private, freeze your credit and get legal help after a scam.
Paying for big goals: College: savings, student loans (federal loans may have lower rates and better repayment terms than private ones), scholarships, grants and work-study. A home: a down payment plus a mortgage with a fixed or adjustable rate. Retirement: Social Security, employer plans, personal investments and any continued work.
Compounding: Earning returns on past returns. Example at a made-up 5% a year: $1,000 grows to about $1,628.89 in 10 years and about $4,321.94 in 30, so starting earlier gives compounding more time.
Risk and expected return: Insured savings accounts and CDs are low risk with lower expected returns; individual stocks are higher risk with higher expected returns. A mutual fund pools many investors' money to buy many stocks or bonds.
Time horizon, risk tolerance and diversification: A long time horizon leaves time to recover from a downturn, so it often goes with riskier assets; a short one with safer assets. Diversification spreads money across assets with different risks and returns, and investors compare results with a benchmark index.
What lowers your return: Transaction, management and advice fees, taxes on interest, dividends and capital gains, and inflation. Real return ≈ nominal return − inflation; example: 6% − 3% ≈ 3%.
Behavioral biases: Overconfidence can lead to unnecessary risks; loss aversion can lead to selling too early at a loss.
