You're opening a checking account at a US bank, and the banker asks if you'd like a credit card too. The offer lists an APR (annual percentage rate) and a minimum payment, says you'll get a credit limit, and asks your permission to check your credit. So far you've paid for everything with cash or a debit card. What is the bank offering, and what will it check?
Credit is borrowing now and repaying later; your credit report records how you've repaid, and lenders check that report to decide whether to lend to you and at what rate.
What does a lender see when it checks my credit?
Three nationwide credit bureaus, Equifax, Experian and TransUnion, keep credit reports, so most people have more than one. Lenders don't have to report to all three, but most bank and nationwide chain-store credit cards, along with loans, appear in the reports. A report lists each account's type, its credit limit or loan amount, its balance and your payment history.
A credit score is a prediction, calculated from a credit report, of how likely you are to repay on time. Lenders use your report and scores to decide whether to lend to you, at what interest rate and with what limit. A higher score usually makes it easier to qualify and may bring a better rate. See what counts as a good credit score and how it's built.
When you apply, the lender's check is a hard inquiry, which may affect your FICO scores; viewing your own report doesn't. Landlords, insurers and phone or utility companies may check your report too.
Your income and bank balances aren't in your report. Lenders often ask about your income on the application. Paying with cash or a debit card isn't borrowing, so it typically isn't reported and doesn't build a credit history. FICO needs at least one account open six months or more and one reported in the past six months before it can calculate a score.
How do a credit card and a loan work in real numbers?
Credit comes in two main kinds:
| Type | Examples | How it works |
|---|---|---|
| Revolving | Credit cards, lines of credit | A reusable limit; pay at least the minimum each month. |
| Installment | Car loan, student loan, mortgage | A set amount, usually fixed monthly payments until paid off. |
Example: your new card has a $1,000 limit. You charge $400 of groceries and bills, and your statement shows a $400 balance.
- Pay the full $400 by the due date. With a grace period (the time between the statement and the due date), which most cards give on purchases, you pay $0 in interest. Your $1,000 limit is generally open again.
- Pay only part, and the rest is charged interest at your card's APR; so are new purchases, from the day you make them. In August 2026, bank credit card accounts that were charged interest averaged 22.36% (Federal Reserve, preliminary). Pay $100 and carry $300: a month at that rate costs about $5.59 ($300 × 22.36% ÷ 12).
Example: a $20,000 new-car loan for 60 months at 7.54%, the average rate commercial banks most often charged on such loans in August 2026 (Federal Reserve, preliminary). You pay $401.14 a month, 60 times: $24,068 in all, of which $4,068 is interest.
A card with a $0 balance is credit without debt. Scores look at how you handle both kinds, but FICO says a small loan taken just to show you can manage one is "probably not" worth it.
What can I do today?
- If you have a Social Security number (SSN) or an Individual Taxpayer Identification Number (ITIN): get your credit report from one bureau at AnnualCreditReport.com (free every week). Next to each account, write "revolving" or "installment", and note any late payment. If there's no report or no accounts, that's your starting point. Don't share your number with us.
- If you have neither: AnnualCreditReport.com needs one, so call your bank or credit union and ask whether its credit cards report to all three bureaus and which ID it accepts.
Can you read your first statement?
Your first statement shows a $1,000 credit limit, a $400 statement balance from purchases and a minimum payment. What should you pay by the due date to avoid interest?
- A. The minimum payment
- B. The $400 statement balance ✅
- C. The $1,000 credit limit
Why: the statement balance is what you borrowed, and paying it in full by the due date usually avoids interest on purchases; paying only the minimum leaves the rest to be charged interest, and the limit isn't a bill.
