1. Saving for Future Purchases

Topic 3.1 · Project Task 1 (Financial Survival Guide for Teens)

• Income: money earned from a job, self-employment, investments, rental property, government programs, or retirement accounts. Most people earn it by working for a business, a nonprofit, or the government.
• Saving: putting part of your money away for later rather than spending it today. Money you save becomes something you own (an asset), and it can pay you interest, which is another way to earn income.
• How much interest you'll earn depends on the rate, your balance, the kind of account, and what's happening in the economy.

Why people save

What helps people save, and what gets in the way

• Incentives: automated savings plans move a set amount into savings every payday; retirement savings plans lower your taxes when you save for retirement (and many employers add a matching contribution); health savings accounts lower your taxes on money set aside for medical costs.
• Financial barriers: inconsistent income, or recurring expenses that are bigger than income.
• Psychological barriers: instant gratification (wanting things now instead of waiting), impulse buying (unplanned, emotional purchases), and lifestyle inflation (spending rises every time income rises, also called lifestyle creep).

PESTEL forces that change the value of saving

Outside forces affect both whether people can save and whether they want to. Keep the focus on the individual saver.

Building a savings plan

1. Assess income and expenses to see what's left over each month.
2. Clarify goals and identify barriers: what are you saving for, by when, and what usually stops you?
3. Choose savings vehicles that fit each goal's timeline and risk.
4. Formalize it: set the monthly amount each goal needs and automate the transfers.
5. Monitor progress, including the interest rate you're earning.
6. Adjust when your income, expenses, or goals change.

Where to save: savings vehicles

• Insurance on deposits: the FDIC (banks) and NCUA (credit unions) insure deposits up to $250,000 per depositor, per institution, per ownership category. Stocks, bonds, and crypto are not insured, and neither is a money market fund sold by an investment company (a money market account at a bank or credit union is).
• Principal: the original amount you deposit or invest, not counting interest.
• Where to bank: a commercial bank is a for-profit business owned by shareholders; a credit union is a nonprofit owned by its members, often with lower fees and better rates; online banks often pay the highest rates but have no branches.
• The tradeoffs: higher interest usually means less access (a CD), easy access can mean more temptation, and high-rate accounts may need a minimum balance you can't meet.

2. Borrowing, Credit, and Debt

Topic 3.2 · Project Task 2 (Financial Survival Guide for Teens and PSA)

People borrow so they can spend more than their current income and savings, expecting their income to catch up so they can repay. Common reasons: large, lasting purchases (a home, a car, education or job training), emergencies (a leaking roof, an illness), gaps between paychecks, and convenience (credit cards).

The language of a loan

Where people borrow

• Commercial banks and credit unions: personal loans, auto loans, mortgages, credit cards.
• Stores: their own financing offers and pay-in-installments plans at checkout, often for phones, furniture, or appliances.
• Mortgage lenders: specialize in loans to buy, build, or renovate homes.
• Alternative financial services: payday loans, check cashing, and instant tax refunds. They're fast and usually skip the credit check, but they cost far more than a loan from a bank or credit union.
• Consumer protection: federal, state, and local laws require lenders to explain terms clearly and ban discrimination in lending. Examples: the Truth in Lending Act (lenders must disclose the APR and terms), the Equal Credit Opportunity Act (no discrimination), and the Fair Credit Reporting Act (your credit report must be accurate, and you can dispute errors).

How lenders judge creditworthiness

Creditworthiness is how likely you are to repay on time. Failing to repay is called default. Credit bureaus (Equifax, Experian, and TransUnion) collect your borrowing history into a credit report, and a credit score turns that history into a number. FICO scores run from 300 to 850. Scores of about 700 and up are generally considered good, while scores below about 600 can mean much higher rates or a denial.

Besides the score, lenders look at your ability to repay (income compared with your existing debt payments), your savings and assets, any collateral, and your track record.

Borrow now, or wait?

• Borrowing can make sense for a true need (health, safety, school, work) or something that helps you earn income, when the payments fit your budget and you understand the terms.
• Be cautious when it isn't urgent and you could save up, or when the payments would leave no room in your budget. If you do borrow, borrow as little as possible, set up autopay, and pay more than the minimum.
• Don't borrow for wants or impulse buys at high rates, when you don't understand the terms, or when you could only afford the minimum payment.

Managing debt and using credit wisely

• Build and protect your credit score: pay on time, keep credit utilization low, and avoid opening accounts you don't need.
• Get better loan terms: compare lenders, make a bigger down payment (an upfront payment from savings that shrinks the loan and can lower the rate), choose a shorter term, or offer collateral.
• Pay off the highest-interest debt first, usually credit cards, and pay more than the minimum.
• Build an emergency fund so the next surprise doesn't go on a high-interest credit card.
• If debt becomes unmanageable after a job loss or emergency, debt management assistance can help: credit counseling, debt management plans, debt consolidation, and debt settlement. Bankruptcy is a legal process that wipes out some debts and sets a repayment plan for others. It's a last resort that hurts your credit for years.

3. Accounting and Financial Management

Topic 3.3 · Project Task 3 (Startup Finance Summit begins: Part A, Business Summary)

Why everyone tracks financial data

• Consumers track income and spending with budgets, spreadsheets, or apps so they can make decisions (can I afford this?), avoid overspending, and see their net worth: assets (what you own, including savings) minus liabilities (what you owe).
• Businesses track every way money comes in (sales, owner investment, loans, grants) and goes out (costs, expenses, equipment) to measure performance, make decisions, pay taxes, and report to owners, investors, and lenders. Much of this tracking is legally required.
• Accounting is recording, organizing, and reporting financial data. Financial statements are the formal summaries: the income statement, balance sheet, and cash flow statement.
• GAAP (Generally Accepted Accounting Principles) is the set of rules publicly traded U.S. companies follow when they report. Public companies must report bad news as well as good, so investors aren't misled.

Who does what

A simple way to remember it: accounting keeps score and finance is the coach who uses the score to plan the next move.

4. Business Expenses

Topic 3.4 · Project Task 4 (Business Canvas: Startup costs · Startup Finance Summit Part B, Estimated Costs)

Startup costs

Startup costs are the expenses a new business faces as it gets ready to open. They come in two kinds:

Many founders also set aside a working capital reserve, cash to cover a few months of operating expenses while sales build up. Startup costs are usually higher than people guess, which is why the estimate matters so much for funding.

Classifying recurring business costs

Once the business is running, its recurring costs are sorted two ways.

• Direct costs are tied to producing or delivering a particular good or service.
  • For businesses that make or sell goods, direct costs are the cost of goods sold (COGS): raw materials, production supplies, production workers' wages, factory rent and utilities, packaging for the finished product. For a store, it's what it paid for the merchandise it sold.
  • For service businesses, direct costs are the cost of sales: the pay of the people delivering the service, travel to serve clients, and materials used on the job.
• Indirect costs, also called operating expenses, are the day-to-day costs of running the business that aren't tied to one product: office or store rent, utilities, insurance, office and sales staff (like cashiers), advertising, sales commissions, software, office supplies, and accounting or legal fees.
• Costs are also fixed (stay the same as output changes: rent, insurance, salaries) or variable (rise as output rises: ingredients, materials, packaging, shipping per order). COGS can include both, such as fixed factory rent and variable ingredients.

Insurance and risk

Insurance spreads risk across many people so that no one person or business suffers a loss too big to survive. Businesses buy property and liability insurance and workers' compensation insurance, which covers employees hurt or made sick on the job. Consumers buy health, auto, renters or homeowners, and life insurance.

5. Financial Capital

Topic 3.5 · Project Task 5 (Business Canvas: Potential sources of financial capital and Pitch · Startup Finance Summit Part C, Funding Strategy)

Why businesses need outside money

• Financing is getting the money to start, run, or grow a business. That money is financial capital.
• Businesses look outside when startup costs are bigger than the founder's savings, to buy fixed assets (buildings, land, vehicles, equipment), to expand or launch products, and to cover cash gaps, like paying staff before a big customer pays. Even a profitable business may need outside capital to grow or to bridge timing gaps.
• Bootstrapping means funding the business yourself with savings or a personal credit card. You keep full ownership, but the amount is limited and your own finances are on the line.

Debt or equity?

• A bond is a loan from an investor: the company sells the bond, pays interest, and repays the principal at the end. A stock is a share of ownership.
• Grants and pitch competitions are neither debt nor equity: no repayment and no ownership, but they're competitive and take time to win. Crowdfunding raises small amounts from many people, usually with fees.
• New businesses with no sales history often can't get bank loans, which is why so many start with savings, family, and grants.
• Lenders and investors can resell bonds and stocks in secondary markets. Buying a company's bond, even secondhand, makes you a lender. Buying its stock makes you an owner.

• Risk tolerance is how much risk someone is willing and able to accept. A venture capitalist has more than a traditional bank lender.
• Risk and return go together: riskier investments, and those tied up for longer, have to offer a higher expected return to attract money. Riskier borrowers pay higher interest rates for the same reason.

Pitching lenders and investors

A business plan lays out goals, the value proposition, market research, marketing strategy, and financial projections. A pitch is a short, persuasive presentation of that plan with a clear funding request. A strong pitch includes:

• a hook, the product, the target customer, and the problem, need, or want it solves;
• how it creates value for customers;
• how much money you need and exactly what it will pay for;
• the type of funding: a loan with a repayment plan, or equity with the ownership share you're offering;
• evidence and risk reduction: MVP results, pre-orders or survey data, realistic projections, collateral, and a capable team;
• a clear closing “ask.” An investor is asking what a share of the business could be worth someday; a lender is asking how and when the loan gets paid back.

6. The Income Statement

Topic 3.6 · Project Task 6 (Business Canvas: Revenue projection and projected income statement · Startup Finance Summit Parts D and E)

An income statement (also called a statement of profit and loss, or P&L) summarizes a business's revenue and costs, and the resulting profit or loss, over a period of time such as a month, quarter, or year. It answers: did the business make a profit?

• Selling expenses are the costs of marketing, selling, and delivering. General and administrative expenses are the costs of running daily operations, like office salaries, rent, and insurance. Research and development counts as an operating expense too.
• Interest expense comes from the business's funding decisions: more debt means more interest.
• Startup costs aren't one of the regular lines on an income statement, because they aren't recurring costs of operating.
• Net profit is also called net income, income after taxes, or the “bottom line.”

Judging performance: margins and percent change

• Per-unit view: if a muffin sells for $4.00 and its ingredients and packaging cost $1.50, each muffin brings $2.50 of gross profit.
• Ways to improve profit: raise prices (if customers will accept it), lower COGS (cheaper suppliers, less waste), cut operating expenses, sell more, or shift toward higher-margin products.

Planning ahead: projected income statements and budgets

• A projected income statement forecasts revenue, expenses, and profit for a future period. It starts with a revenue projection: projected units sold × price.
• Ways to project revenue: past sales trends, market research (surveys, pre-orders, demand tests), what similar businesses sell, capacity limits (how much you can actually make), PESTEL conditions, and scenarios (conservative, most likely, optimistic).
• Revenue projections must reflect real demand and your pricing; COGS projections depend on your supply chain and production plans.
• Consumers do the same thing with a budget, a plan for dividing income among expenses and savings. Both plan for uncertainty. The difference: a budget plans one person's or household's income, spending, and saving, while a projected income statement forecasts a business's revenue, costs, and profit.

7. The Balance Sheet and Net Worth

Topic 3.7 · Project Task 7 (Startup Finance Summit Part E, estimated startup balance sheet)

A balance sheet shows what a business owns, what it owes, and the owners' share at one point in time. If the income statement is a video of a period, the balance sheet is a photo of one moment. It answers: is the business financially stable?

What's on a balance sheet

• Liquidity is how easily an asset turns into cash. Balance sheets list the most liquid assets first.
• Current assets are highly liquid and used for daily operations: cash (currency and checking deposits), short-term investments (sold within a year), accounts receivable (money customers owe for things already delivered), and inventory (goods to sell and the materials to make them).
• Long-term assets help the business earn money for more than a year: fixed assets (tangible: buildings, land, vehicles, machinery), long-term investments (stocks, bonds, or real estate held over a year), and intangible assets (nonphysical: patents, trademarks, copyrights, brand names, goodwill).
• Liabilities are what the business owes to lenders, suppliers, employees, or the government. Current liabilities are due within a year: accounts payable (owed to suppliers), short-term debt, current payments on long-term debt (the slice of a long loan due this year), and accrued expenses (costs already incurred but not yet paid or billed, like wages employees have earned). Long-term liabilities are due later: long-term loans, bonds, and mortgages (property loans that give the lender a claim on the property).
• Owners' equity is the owners' investment plus retained earnings: profit the business has kept and reinvested instead of paying out as dividends. Losses or dividends shrink retained earnings, which can even go negative.

Reading it like a lender

• Lenders care about liquidity and working capital (can you pay me back soon?) and how much the business already owes, not just its total net worth. A business, or a person, can be “rich on paper” with wealth tied up in buildings or equipment and still struggle to pay this month's bills.
• A strong balance sheet (solid assets, manageable debt, reinvested earnings) opens doors: bank lines of credit, 30-day payment terms from suppliers, and better insurance rates.
• Bankruptcy is the legal process businesses and individuals use to get relief from debts they can't repay.

Every transaction keeps it balanced

Personal net worth

Households use the same formula: net worth = assets − liabilities. A household is everyone living in one home. Tracking net worth shows your overall financial health, measures progress over time, matters when you apply for loans, and helps you plan goals like buying a home or retiring.

8. The Cash Flow Statement

Topic 3.8 · Project Task 8 (Startup Finance Summit Part F, Financial Strategy)

A cash flow statement tracks cash moving in and out of a business during a period. Cash inflows raise the cash balance; cash outflows lower it. Ending cash = beginning cash + net change in cash.

Profit is not the same as cash

Revenue counts when it's earned, even if the customer hasn't paid. A sale on account raises revenue but becomes accounts receivable, not cash. Collecting last month's receivable brings in cash with no new revenue. Buying equipment uses cash but isn't an expense of the month, and loans bring cash but aren't revenue.

How stakeholders use it

• Lenders check whether operating cash can cover loan payments; suppliers decide whether to sell on credit; managers plan for shortages; investors judge stability and growth.
• A negative month isn't always bad: a growing business may spend heavily on inventory and equipment. But a mature business with negative operating cash flow month after month can fail even while reporting a profit, because it can't pay its bills.
• Big investing outflows usually mean the business is investing in growth. The financing section shows how much it relies on borrowing or selling stock.
• Fixing a cash shortage: collect receivables faster, negotiate longer supplier terms, cut or delay costs, build a cash reserve, adjust prices, or use a line of credit (borrow as needed, like a credit card, but it adds interest).
• Nonprofits face the same problem: donations and grants often arrive in bunches (like the end of the year) while salaries are due every payday, and some grants can only be spent on specific programs.

9. Ethics and Financial Reporting

Topic 3.9 · Project Task 9 (Startup Finance Summit Part G, Financial Reporting)

Why people cross the line

• Pressure and rewards: bonuses or stock prices tied to hitting profit targets, or personal money problems.
• Personal benefit: using business resources to make life easier.
• Opportunity: authority without oversight, like one person who can approve purchases that benefit themselves.
• Rationalization: “I saved the company money, so I've earned this,” or “it's tax-deductible anyway.”

Pressure, opportunity, and rationalization together are sometimes called the fraud triangle. Take away one side, especially opportunity, and misconduct gets much harder.

What keeps financial managers honest

• Laws and punishments: countries outlaw fraud, embezzlement, bribery, tax evasion, and misuse of funds. Laws and penalties vary from country to country, and serious penalties are a strong deterrent.
• Reporting rules and audits: in the U.S., the SEC (Securities and Exchange Commission) requires public companies, whose stock trades on an exchange, to file their income statement, balance sheet, and cash flow statement every quarter and make them public, and each year an independent accounting firm audits the annual statements.
• Professional codes of ethics: professional organizations for accountants and financial managers hold members to ethical standards. Codes matter even where laws exist, because they guide behavior in gray areas and set expectations for the whole profession.
• Internal controls: separation of duties (split tasks so no one person controls a whole transaction, like approving, paying, and recording a purchase), internal audits (an independent review of the business's own finances and processes), spending limits that need a second approval, receipts and documentation, conflict-of-interest disclosures, and protection for whistleblowers.
• Transparency means sharing information openly, honestly, and clearly with stakeholders.

10. Culminating Event: Startup Finance Summit

Project Task 10 · Business Canvas Project Unit 3 deliverables

You act as the finance manager for your Business Canvas Project business. You present a finance portfolio and a short investor pitch (about 200 words) to an “investor panel” and answer their questions. The portfolio pulls together your work from Tasks 3 through 9:

• Your pitch needs: the value proposition (what problem you solve, for whom), the funding request (amount and loan or equity), the use of funds, how you've reduced risk, and the return story (why the funder benefits).
• Be honest with your numbers. If your projected income statement shows a loss, that's useful information, not a failed project. Explain what would need to change (price, volume, costs, or product mix) to make it work.
• Business Canvas Project deliverables from Unit 3: startup costs, potential sources of financial capital, a revenue projection, your pitch, and an actual or projected income statement. FRQ 1 on the AP Exam asks about your own project, so know these numbers well. See the Canvas Project guide.

How Unit 3 Shows Up on the Exam

• Multiple choice: Unit 3 is 25–35% of Section I, the most of any unit, and personal finance alone is roughly 20–25% of the multiple-choice questions. Many questions come in sets built on a short case, often with a table: a loan offer, a savings comparison, an income statement, or a balance sheet. Expect to calculate and interpret, not just define.
• Math to know cold: savings per month for a goal, total cost and total interest of a loan, credit utilization, startup cost totals, break-even units, rate of return, every line of the income statement, the three margins, percent change, the balance sheet equation, working capital, net worth, and net change in cash.
• FRQ 2 (Personal Finance): expect questions on saving, borrowing, credit, and net worth.
• FRQ 1 (Business Canvas Project): your startup costs, funding sources, revenue projection, and income statement are part of what you'll explain.
• Not tested: compound interest calculations. You may calculate a total return over several years, but turning it into a yearly (annualized) rate is beyond the course, so don't call a multi-year total an annual rate.
