16.2 Consumer Economics: Credit, Savings & Banking
Key Takeaways
- The three types of consumer credit are revolving (credit cards), installment (fixed-payment loans like auto or mortgage loans), and service credit (utilities billed after use).
- The Truth in Lending Act (1968) requires lenders to disclose the Annual Percentage Rate (APR) and total cost of credit before a borrower signs.
- The Equal Credit Opportunity Act (1974) makes it illegal for lenders to deny credit based on race, color, religion, national origin, sex, marital status, or age.
- FDIC insurance protects up to $250,000 per depositor, per bank, per ownership category if a bank fails.
- Consumer economics questions on the GED often use workplace or real-life stimuli, such as a bank disclosure form or a 'know your rights' flyer — read the document carefully before answering.
Why This Topic Matters
Consumer economics (blueprint code E.e) is one of the most practical parts of the entire GED Social Studies test — it is designed to measure whether an adult can navigate real financial decisions: reading a credit card offer, choosing a savings vehicle, or knowing which law protects them if a lender treats them unfairly. Because the test frequently uses workplace and everyday-life stimuli (a bank disclosure statement, a credit card agreement excerpt, a consumer rights flyer), this is a topic area where careful reading of the provided document matters just as much as memorized vocabulary.
Types of Credit (E.e.1)
Credit means receiving money, goods, or services now with an agreement to repay later, typically with interest — the cost of borrowing, usually expressed as an Annual Percentage Rate (APR). The GED blueprint recognizes three broad categories:
| Type of Credit | How It Works | Common Example |
|---|---|---|
| Revolving credit | A set credit limit that can be borrowed against repeatedly; carrying a balance accrues interest; minimum payments are required each month | Credit cards, store charge cards, home equity lines of credit |
| Installment credit | A fixed loan amount repaid in equal payments over a set term at a fixed or variable rate | Auto loans, mortgages, student loans, personal loans |
| Service credit | An agreement to pay for a service after it has already been provided, usually with no interest if paid on time | Electric, gas, water, and phone bills |
Worked example: A borrower carries a $1,000 balance on a credit card with a 20% APR and makes no payments for one year. At a simple approximation, interest alone would add about $200 to the balance ($1,000 × 0.20), and because credit card interest typically compounds monthly, the actual amount owed after a year of no payments would be somewhat higher than $200. This is why revolving credit is the most expensive form of consumer credit when a balance is carried month to month, compared with an installment loan at a lower, fixed rate.
Savings & Banking (E.e.2)
Banks offer several tools for storing and growing money, each with a different trade-off between liquidity (how quickly you can access the money) and return (how much interest it earns):
- Savings account — Highly liquid, low interest rate, funds can typically be withdrawn at any time.
- Certificate of Deposit (CD) — Funds are locked in for a fixed term (e.g., 12 months); in exchange for reduced liquidity, the interest rate is usually higher than a savings account. Withdrawing early triggers a penalty.
- Money market account — A hybrid account, often requiring a higher minimum balance, that pays a rate between a savings account and a CD while still allowing limited withdrawals.
Compound interest — interest calculated on both the original principal and on interest already earned — is the reason savings grow faster over long periods than simple interest would suggest. A basic version of the formula is A = P(1 + r/n)ⁿᵗ, where P is the principal, r is the annual interest rate, n is the number of times interest compounds per year, and t is the number of years. You will not be asked to solve this formula by hand on the GED; you need to recognize that compounding means interest earns more interest over time, which is why starting to save early matters more than the size of any single deposit.
A critical consumer-protection fact: deposits at FDIC-insured banks are protected up to $250,000 per depositor, per insured bank, per ownership category if the bank fails. This is why the Federal Deposit Insurance Corporation (FDIC), created during the New Deal (see Chapter 9), remains one of the most consequential pieces of banking regulation for ordinary savers today.
Consumer Credit Laws (E.e.3)
A series of federal laws regulate how lenders must treat consumers. Confusing these laws with one another is a common exam trap, so learn each by its core purpose:
| Law (Year) | Core Protection |
|---|---|
| Truth in Lending Act — TILA (1968) | Requires lenders to clearly disclose the APR, finance charges, and total cost of a loan or credit card before the borrower signs |
| Fair Credit Reporting Act — FCRA (1970) | Governs the accuracy and privacy of credit reports; gives consumers the right to dispute errors and access a free annual credit report |
| Equal Credit Opportunity Act — ECOA (1974) | Makes it illegal to deny credit based on race, color, religion, national origin, sex, marital status, or age |
| Fair Debt Collection Practices Act — FDCPA (1977) | Restricts abusive, unfair, or deceptive practices by third-party debt collectors (e.g., no threatening calls at 3 a.m.) |
| Credit CARD Act (2009) | Restricts sudden interest rate increases on existing balances and requires clear disclosure of how long it will take to pay off a balance making only minimum payments |
Exam Scenario: A stimulus shows a letter from a debt collector who calls a consumer's workplace repeatedly and threatens legal action that isn't actually planned. The question asks which federal law this behavior most likely violates. The correct answer is the Fair Debt Collection Practices Act, because it specifically restricts the behavior of debt collectors — not the terms of the original loan (TILA), not the content of a credit report (FCRA), and not discrimination in the lending decision itself (ECOA).
Common Trap
Do not confuse TILA (what a lender must disclose before you borrow) with the Credit CARD Act (what a credit card company must do after you already have an account, such as limiting rate increases). Both concern disclosure, but TILA applies broadly to loans and credit at the point of origination, while the CARD Act specifically targets ongoing credit card account practices.
A consumer buys a car with a loan requiring 60 equal monthly payments at a fixed interest rate. What type of credit is this?
Which federal law requires lenders to disclose the Annual Percentage Rate (APR) and total finance charges before a consumer signs a loan agreement?
A bank denies a qualified applicant a loan explicitly because of her marital status. Which law has the bank most likely violated?
