Compare the costs and benefits of credit from different financial institutions, manage credit and debt to maintain creditworthiness, and explain consumer protection laws

Learning goal: Explain the costs and benefits associated with various sources of credit available from different types of financial institutions, explain how credit and debt can be managed to maintain creditworthiness, and describe how consumer protection laws provide financial safeguards.

What credit is. Credit is the ability to obtain goods, services or money now in exchange for a promise to pay later, usually with interest. Debt is the amount owed. The principal is the amount borrowed; interest is the price of borrowing; the annual percentage rate (APR) expresses the yearly cost of credit as a percentage. For an installment loan, the APR includes interest and certain fees, so loans of the same amount and term can be compared by APR. For a credit card, the purchase APR is the yearly interest rate on balances carried; annual, late, balance-transfer and cash-advance fees are disclosed separately and must be compared separately. Even for loans, APR alone does not give the total cost: a longer term at a lower APR can cost more in total, so compare the APR, the fees, the repayment period and the total of all payments. Credit has real benefits: it lets people buy a car to get to work, pay for education, handle an emergency, or buy a home decades before they could save the full price. Its costs are interest, fees, and the risk of taking on payments that become unaffordable.

Sources of credit and the institutions behind them. Commercial banks offer credit cards, car loans, personal loans and mortgages; they are for-profit and often require good credit for their best rates. Credit unions are member-owned, not-for-profit cooperatives; they offer similar loans and often charge somewhat lower rates or fees, but you must qualify for membership. Credit card issuers provide revolving credit: you can borrow up to a limit, repay and borrow again. Paying the full statement balance by the due date usually avoids interest on purchases; carrying a balance usually costs a high APR. Finance companies and dealers offer loans for cars, furniture or electronics, sometimes to borrowers with weaker credit at higher rates. Payday lenders offer small, short-term loans due on the borrower's next payday; they are fast and require little credit history, but the fees translate into very high APRs. A hypothetical fee of 15 dollars per 100 dollars borrowed for two weeks equals 15% per two weeks, or 15 × 26 = 390% as a simple annual rate. Buy-now-pay-later plans split a purchase into a few installments, sometimes without interest, but late fees and multiple overlapping plans can create problems. Choosing among sources means comparing APR, fees, repayment terms and flexibility.

A fully worked model. A hypothetical borrower needs 5,000 dollars for a used car, to be repaid in 36 equal monthly payments. The payment on a loan of L dollars at monthly rate i for n months is M = L·i ÷ [1 − (1 + i)^(−n)]. Assume both offers are fixed-rate loans with no fees, so the APR equals the interest rate used to compute the payment (with fees, the APR is higher than the rate and the fees must be compared too). Offer A, a credit union, 9% APR: i = 0.09 ÷ 12 = 0.0075, and M ≈ 159.00 dollars. Total paid 36 × 159.00 = 5,724.00, so interest is 724.00 dollars. Offer B, a finance company, 18% APR: i = 0.015, M ≈ 180.76 dollars; total 6,507.36, interest 1,507.36 dollars. Doubling the APR more than doubled the interest cost. The borrower's credit history helps determine which offers are available, which is why creditworthiness matters.

Creditworthiness and credit scores. Creditworthiness is a lender's judgment of how likely a borrower is to repay. Lenders rely on a credit report, a record kept by credit bureaus of a person's accounts, balances, payment history and public records, and on a credit score, a number calculated from the report. Widely used scoring models run from 300 to 850, higher meaning lower risk. Scoring companies describe the main factors as payment history (whether bills were paid on time), amounts owed (especially credit utilization, the share of available revolving credit in use), length of credit history, new credit applications and the mix of credit types; payment history and amounts owed are generally described as the most important. A person with a 3,000-dollar total card limit and a 900-dollar balance has a utilization of 900 ÷ 3,000 = 30%.

Managing credit and debt. Credit and debt can be managed to maintain credit worthiness by: paying every bill on time, since late payments are recorded; keeping balances low relative to limits; paying more than the minimum on cards; borrowing only what a budget can repay; applying for new credit only when needed; and checking credit reports for errors. The cost of paying slowly is large. A hypothetical 1,000-dollar card balance at 24% APR (2% a month), with no new charges, takes 26 monthly payments of 50 dollars (the last smaller) to pay off, costing about 1,289.87 dollars in total. Paying 100 dollars a month clears it in 12 payments for about 1,127.03 dollars.

Consumer protection laws provide financial safeguards. Several federal laws, described here only in general terms, protect borrowers. The Truth in Lending Act (1968) requires lenders to disclose the APR and finance charges in a standard form so consumers can compare credit offers. The Fair Credit Reporting Act (1970) regulates credit bureaus: consumers may see their reports, dispute inaccurate information and have errors corrected; consumers can obtain free reports from each nationwide credit bureau through the site the law authorizes. The Equal Credit Opportunity Act (1974; its protections were widened in 1976) prohibits lenders from discriminating on the basis of race, color, religion, national origin, sex, marital status or age, among other grounds. The 1974 law covered sex and marital status; the 1976 amendments added the other grounds. The Fair Debt Collection Practices Act (1977) bars debt collectors from harassment, false statements and certain unfair practices. The Credit CARD Act of 2009 added rules on card rate increases and fees and generally requires applicants under 21 to show independent income or have a co-signer. The Consumer Financial Protection Bureau, created by a 2010 law, enforces many of these rules and accepts complaints; in Ohio, the Attorney General's office also handles consumer complaints. These safeguards do not stop a person from borrowing unwisely; they ensure information, fairness and a way to correct errors.

The misconception. "Making the minimum payment keeps me out of trouble." It keeps the account current, but a small payment reduces the principal slowly, so the balance is charged interest for many more months and the debt costs far more; when a payment barely covers the month's interest, most of it goes to interest.

Worked example 1 — comparing two loan offers: L = 5,000, n = 36. At 9% APR, i = 0.0075: M = 5,000 × 0.0075 ÷ [1 − 1.0075^(−36)] ≈ 37.50 ÷ 0.23585 ≈ 159.00 dollars; total 5,724.00; interest 724.00. At 18% APR, i = 0.015: M ≈ 180.76; total 6,507.36; interest 1,507.36. The lower-APR source saves 783.36 dollars over three years.

Worked example 2 — paying down a card balance: 1,000 dollars at 24% APR (2% per month), no new charges. Month 1: interest 0.02 × 1,000 = 20.00; after a 50-dollar payment the balance is 970.00. Month 2: interest 19.40; balance 939.40. Continuing, the balance reaches zero with the 26th payment, total paid about 1,289.87 dollars. At 100 dollars a month it takes 12 payments, about 1,127.03 dollars. Paying more each month saves about 162.84 dollars and 14 months.

Worked example 3 — protecting creditworthiness with a report check: A hypothetical student requests a free credit report and finds a late payment on an account she never opened. Under the Fair Credit Reporting Act she can dispute the entry with the credit bureau, which must investigate and correct inaccurate information. She should also consider that the unknown account may signal identity theft and take further steps. Correcting the error protects her score before she applies for a car loan.

Credit comparison record: For a hypothetical 3,000-dollar purchase, compare three sources: a credit union loan at 8% APR for 24 months, a store card at 26% APR paid at 150 dollars a month, and a payday-style loan with a hypothetical fee of 15 dollars per 100 dollars, repaid in full after two weeks. Record the monthly payment or fee, total cost, and one non-price benefit and one risk of each.

Independent performance: Write a one-page guide for a first-time borrower. Success criteria: you explain APR, principal and interest; you compare at least three sources of credit from different types of financial institutions, naming a cost and a benefit for each; you list at least four practices that maintain creditworthiness and explain how each affects a credit score factor; you compute utilization and one loan payment correctly; you describe what three consumer protection laws do in general terms, with their years; and you give no recommendation of a specific lender or product.
