What Is APR?
APR stands for annual percentage rate, the yearly price of borrowing money. It tells you how much a loan or credit card costs over a year, as a percentage of what you borrow. The Consumer Financial Protection Bureau (CFPB) describes it as a broader measure of the cost of borrowing than the interest rate alone.12
The measure exists to make comparison easier. US law, through the Truth in Lending Act and its rules known as Regulation Z, requires lenders to show it on most consumer credit.3 That way, two offers with different fees and rates can be compared on one number.
You will see it on credit cards, personal loans, car loans, mortgages, student loans and buy now, pay later plans with interest. The higher the rate, the more the borrowing costs you.
APR vs Interest Rate
The interest rate is the cost of the money itself, while APR adds certain required fees to show the fuller cost. For many loans, that makes it the more honest number to compare.
| Measure | What it includes | Best used for |
|---|---|---|
| Interest rate | Only the cost of borrowing the principal | Working out the monthly payment |
| APR on a loan | Interest rate plus certain fees, such as origination fees or mortgage points | Comparing the total cost of different loans |
| APR on a credit card | The yearly interest rate on balances you carry | Comparing cards and estimating interest |
On a mortgage, the gap can be meaningful. The CFPB explains that a mortgage APR includes the interest rate plus points, broker fees and certain other charges.2 A loan with a lower rate but high fees can end up costing more than a loan with a slightly higher rate and no fees.
The measure is not perfect. It assumes you keep the loan for its full term. If you plan to repay or refinance early, upfront fees weigh more heavily than the headline figure suggests.
How APR Works on Credit Cards
On a credit card, APR is the yearly interest rate charged on balances you do not pay off in full. Most cards charge interest daily, based on your balance each day.
Card issuers turn the yearly rate into a daily periodic rate. They usually divide it by 365. On a card charging 24% a year, the daily rate is about 0.066%. Interest is added each day to the balance, so you also pay interest on past interest.
The Grace Period
Most cards give you a grace period on new purchases. Clear everything shown on your statement before the due date and those purchases usually cost nothing in interest. Federal rules require card issuers to mail or deliver statements at least 21 days before the payment is due.3
The grace period usually disappears if you carry a balance from the previous month. Interest can then apply to new purchases from the day you make them. Paying in full every month is the simplest way to avoid card interest altogether.
Credit Card Rates Today
Card rates are high compared with most other borrowing. Federal Reserve data on consumer credit has shown average rates on card accounts that pay interest above 20% in recent years.4 Your own rate depends on the card and on your credit history.
Types of APR You Might See
A single credit card can have several APRs, each for a different kind of balance. Your card agreement lists them in a standard summary table, sometimes called the Schumer box.
- Purchase APR: the rate on everyday purchases you do not pay off in full.
- Balance transfer APR: the rate on debt moved from another card. It is often a low introductory rate, usually with a transfer fee.
- Cash advance APR: the rate when you take cash from an ATM with the card. It is usually higher and often has no grace period.
- Introductory APR: a temporary low or 0% rate. Federal rules generally require it to last at least six months.3
- Penalty APR: a higher rate that can apply after late payments. Under federal rules, it generally applies to existing balances only after a payment is more than 60 days late.3
Fixed vs Variable APR
A fixed rate stays the same unless the lender gives notice of a change. A variable rate moves with a benchmark, usually the prime rate, plus a set margin.
Most credit cards are variable. When the Federal Reserve raises or cuts rates, card rates usually follow. Our explainer on why interest rates change covers the link.

APR is the price of borrowing; APY is what you earn on savings, including compounding. They look similar but point in opposite directions.
| Feature | APR | APY |
|---|---|---|
| Stands for | Annual percentage rate | Annual percentage yield |
| Used for | Loans and credit cards | Savings accounts and CDs |
| Includes compounding? | No, it is a simple yearly rate | Yes, it shows the effect of compounding |
| You want it | Lower | Higher |
Because it leaves out compounding, the true yearly cost of a carried card balance is a little higher than the stated rate. A 24% rate compounded daily works out to an effective rate of about 27% a year. Our explainer on compound interest shows why compounding works against you on debt and for you on savings.
What Affects the APR You Are Offered?
Lenders set your rate mainly on how risky they think lending to you is. Lower risk usually means a lower rate.
- Your credit score: the biggest single factor for most consumer credit. Our explainer on credit scores covers how they work.
- Your income and existing debt: lenders look at whether you can afford new payments.
- The type of credit: secured loans, such as mortgages and car loans, usually cost less than unsecured credit cards.
- The loan term: longer loans sometimes carry higher rates, and they always mean more months of interest.
- The wider rate environment: when benchmark rates rise, most new borrowing becomes more expensive.
Worked Examples: What APR Costs You
These made-up examples use round numbers to show how rates, payments and time interact.
A Credit Card Balance
Alex owes $3,000 on a card charging 24% a year and stops using the card. To keep the maths simple, assume interest of 2% a month. If Alex pays $100 a month, it takes about 47 months to clear and costs about $1,627 in interest.
If Alex pays $200 a month instead, it takes about 19 months and costs about $602 in interest. Doubling the payment cuts the interest by more than half. That is why paying more than the minimum matters so much on high-APR debt.
A Car Loan
Jordan borrows $20,000 for a car over five years. At a 7% rate, the monthly payment is about $396 and total interest is about $3,761. At 12%, the payment rises to about $445 and total interest to about $6,693.
A five-point difference in rate costs Jordan nearly $3,000 more over the loan. Shopping around for a lower rate, or improving credit before borrowing, can save real money. You can test your own figures in our loan repayment calculator.
How to Lower the APR You Pay
You cannot control benchmark rates, but you can control several things that affect your rate and your total interest.
- Pay card balances in full each month, so purchase interest never applies.
- Pay more than the minimum when you carry a balance. Federal rules generally require payments above the minimum to go to the highest-rate balance first.3
- Ask for a lower rate. If you have paid on time for a while, a short call to your card issuer can sometimes reduce your APR.
- Improve your credit score before big borrowing. Paying on time and keeping balances low both help.
- Compare offers by APR, not by monthly payment. A lower payment over a longer term can cost more in total.
- Use 0% offers carefully. A balance transfer can help, but check the transfer fee and have a plan to repay before the promotional rate ends.
Having cash for surprises stops new debt from building up. Our explainer on emergency funds shows how to build one, step by step.
How Rates on Borrowing Affect Your Wider Finances
The interest you pay on debt is money that cannot go toward saving, investing or everyday life. That is why the cost of borrowing matters beyond any single loan.
High-interest debt works like compound growth in reverse. Instead of your money earning a return, the lender earns one from you. A balance that is not paid down can keep growing even if you stop spending on the card.
Paying off a card charging 22% has a similar effect to earning a 22% return, with no risk. Few investments can promise that. For this reason, many people clear expensive debt before investing beyond any employer retirement match.
Borrowing is not always bad. A mortgage can help you buy a home, and a student loan can raise your future income. The key is to borrow for things with lasting value, at the lowest cost you can find, with a clear plan to repay.
Debt, Budgets and Cash Flow
Monthly debt payments also take up room in your budget. Lenders often look at your debt-to-income ratio, the share of your monthly income that goes to debt payments. A lower ratio usually means you will be offered better terms.
Tracking what you owe, the rate on each balance and the minimum payment gives you a clear picture. Many people list their debts from highest rate to lowest and focus extra payments on the top one, a method often called the avalanche approach.
Where to Find the APR
Lenders must show this rate clearly before you sign, so you never have to guess.
- Credit cards: in the summary table of rates and fees in the application and card agreement, and on every monthly statement.
- Mortgages: on the Loan Estimate you receive after applying, and again on the Closing Disclosure before closing.2
- Personal and car loans: in the Truth in Lending disclosure that shows the annual rate, finance charge, amount financed and total of payments.
Read the whole disclosure, not just the headline rate. Check whether the rate is fixed or variable, what fees apply and when any introductory rate ends.
Common APR Mistakes
A few misunderstandings lead people to pay far more interest than they need to.
- Comparing loans by interest rate only, and missing fees that the fuller measure would have shown.
- Making only minimum payments on a high-rate card, which stretches repayment over years.
- Forgetting when a 0% offer ends, leaving a balance that then attracts the full rate.
- Using a card for cash advances, which usually has a higher rate, a fee and no grace period.
- Missing payments, which can trigger a penalty APR and late fees and can hurt your credit score.
Key Terms Explained
- Principal: the amount you borrow, before interest and fees.
- Daily periodic rate: the annual rate divided by 365, used by most cards to charge interest each day.
- Grace period: the time between the end of a billing cycle and the due date, when you can pay in full and avoid purchase interest.
- Prime rate: a benchmark rate many lenders use as the base for variable rates.
- Finance charge: the total dollar cost of credit, including interest and certain fees.
The Bottom Line
APR is the yearly price of borrowing, and a lower one means you keep more of your money. On loans, it adds key fees to the interest rate so you can compare offers fairly. On cards, it is the rate on carried balances, which you can usually avoid by paying in full.
Compare offers on the full annual rate, pay more than the minimum and protect your credit score. For more, browse our money explainers.

Frequently Asked Questions
APR is the yearly cost of borrowing money, shown as a percentage. It helps you compare loans and credit cards on one number.
It depends on your credit and the wider rate environment. Card rates are usually much higher than loan rates, so the best approach is to pay in full each month and avoid interest altogether.
Not always. On loans, APR includes the interest rate plus certain fees, so it is usually higher. On credit cards, the APR and the interest rate are essentially the same.
Most issuers divide the yearly rate by 365 to get a daily rate. They apply it to your balance each day and add the interest to what you owe.
APR is the cost of borrowing and does not include compounding. APY is what you earn on savings and does include compounding.
Yes. Variable rates move with a benchmark, and a penalty rate can apply after late payments. Card issuers must generally give advance notice before raising rates on new transactions.
