Annual percentage rate is the yearly cost of borrowing money, shown as a percentage

Annual percentage rate (APR) is the total yearly cost of a loan or credit line, expressed as a percentage of the amount you borrow. It includes the interest rate plus any fees the lender charges — origination fees, closing costs, or other mandatory charges. A lender must disclose the APR before you sign, so you can compare the true cost of borrowing across different offers.

The APR matters because the interest rate alone does not tell you what you will actually pay. Two loans with the same interest rate can have different APRs if one charges more fees. A mortgage with a 6% interest rate but $2,000 in closing costs will have a higher APR than a mortgage with the same 6% rate and no fees. The APR is the number that accounts for both.

APR is not the same as the interest rate you see advertised. The interest rate is what you pay on the principal — the money you borrowed. The APR wraps in the interest rate plus the cost of fees, spread across the year. This is why lenders are required to show you both numbers: the interest rate shows you the base cost, and the APR shows you the full cost.

Key Takeaways

  • APR includes both the interest rate and any fees the lender charges, so it is always equal to or higher than the interest rate alone.
  • Lenders must disclose the APR in writing before you sign any loan or credit agreement, usually on a document called the Loan Estimate or Disclosure Statement.
  • A lower APR means you pay less money over the life of the loan, so comparing APRs across lenders is more useful than comparing interest rates.
  • APR assumes you keep the loan for its full term; if you pay it off early, your actual cost may be lower than the APR suggests.

How APR is calculated and what it includes

Lenders calculate APR by taking all the costs you will pay — interest, origination fees, closing costs, insurance premiums if required, and any other mandatory charges — and converting them into a single yearly percentage. The formula spreads these costs across the loan term and expresses them as a percentage of the principal.

What goes into the APR depends on the type of loan. For a mortgage, APR includes the interest rate, origination fees, discount points (if you buy them), title insurance, appraisal fees, and other closing costs. For a credit card, APR is usually just the interest rate, because credit cards do not typically charge upfront fees that are included in the APR calculation. For a personal loan, APR includes the interest rate and any origination or processing fees.

What does not go into APR: property taxes, homeowners insurance, HOA fees, late fees, or fees you pay only if you miss a payment. These are real costs, but they are not part of the APR because they depend on your behavior or circumstances, not on the loan itself.

Why APR matters more than interest rate alone

The interest rate tells you only part of the story. Two lenders might offer you a 5% interest rate, but one charges $500 in fees and the other charges $2,000. The one with lower fees will have a lower APR, and you will pay less money overall. If you compare only the interest rate, you might pick the more expensive loan.

APR also lets you compare loans with different terms. A 30-year mortgage and a 15-year mortgage have different interest rates, but the APR accounts for the length of the loan, so you can see which one actually costs less per year. A shorter loan usually has a lower APR because you are paying off the principal faster.

When you are shopping for a loan, always ask for the APR in writing. Lenders are required to provide it, and it is the number you should use to compare offers from different lenders. A difference of even 0.5% APR can save or cost you thousands of dollars over the life of a mortgage or car loan.

APR on credit cards versus installment loans

Credit card APR and loan APR work differently because credit cards do not have a fixed term. A credit card APR is the yearly interest rate you pay on any balance you carry from month to month. If your card has a 18% APR and you carry a $1,000 balance, you will pay roughly $180 in interest over a year (though the exact amount depends on how the card calculates interest daily).

An installment loan — a mortgage, car loan, or personal loan — has a fixed term and a fixed payment. The APR on an installment loan tells you the total yearly cost of borrowing that amount over that specific period. Once you know the APR, you can calculate exactly how much you will pay in total interest and fees by the time the loan is paid off.

Credit cards often show a range of APRs (for example, 15% to 25%) because the rate you receive depends on your credit score and creditworthiness. Installment loans usually show a single APR because the rate is locked in when you sign the agreement.

How APR changes and what affects your rate

Your APR depends on several factors: your credit score, the type of loan, the loan amount, the loan term, and current market interest rates. A borrower with a credit score above 750 will usually receive a lower APR than a borrower with a score of 650, because the lender sees less risk. A 30-year mortgage typically has a lower APR than a 15-year mortgage, because you are spreading the cost over more years.

Market interest rates change constantly, and they affect the APR lenders offer. When the Federal Reserve raises its benchmark rate, lenders raise the APRs they offer to new borrowers. When rates fall, APRs fall too. If you lock in an APR on a fixed-rate loan, that rate does not change for the life of the loan, even if market rates move.

On adjustable-rate loans (like some mortgages or credit cards), the APR can change after an initial fixed period. The disclosure you receive before signing will explain when and how the rate can adjust, and what the maximum APR could be.

What happens if you pay off the loan early

APR assumes you keep the loan until it is fully paid off. If you pay off the loan early, you will pay less interest than the APR suggests, because you are not paying interest for the full term. For example, if you take out a 5-year car loan with a 6% APR but pay it off in three years, your actual cost will be lower than if you kept the loan for five years.

This is one reason APR is not a perfect measure of cost — it is a snapshot based on the assumption that you keep the loan for its full term. If you plan to refinance, sell the home, or pay off the loan early, the actual cost to you will be different from what the APR predicts.

Some loans charge prepayment penalties if you pay them off early, which would increase your actual cost. Always ask whether the loan has a prepayment penalty before you sign, and factor that into your decision.

How to compare APRs when shopping for a loan

When you are comparing loans, request the APR in writing from each lender. The Truth in Lending Act requires lenders to disclose the APR clearly, usually on a document called a Loan Estimate (for mortgages) or a Disclosure Statement (for other loans). These documents must show the APR, the interest rate, the loan amount, the term, and the total amount you will pay.

Line up the APRs side by side and choose the lowest one, assuming all other terms are the same (loan amount, term, and type). If the terms are different — for example, one loan is 30 years and another is 15 years — you can still use APR to compare, but remember that the shorter loan will have a lower APR partly because you are paying it off faster.

Do not let a lender quote you only the interest rate. Always ask for the APR, and always get it in writing before you commit. The difference between a 5.5% APR and a 6% APR on a $300,000 mortgage is tens of thousands of dollars over 30 years.

Frequently Asked Questions

Is APR the same as the interest rate?

No. The interest rate is what you pay on the principal. The APR includes the interest rate plus all mandatory fees, spread across one year. The APR is always equal to or higher than the interest rate.

Can APR change after I sign the loan?

On a fixed-rate loan, the APR does not change. On an adjustable-rate loan, the APR can change after an initial fixed period — the disclosure you receive before signing will explain when and by how much. Credit card APRs can also change, though card issuers must give you notice before the change takes effect.

Why do two lenders offer different APRs for the same loan?

Lenders charge different fees and have different costs, so they offer different APRs even for the same loan amount and term. Your credit score also affects the APR you receive — a higher score usually means a lower APR. Always compare APRs across multiple lenders before you choose.

Does APR include property taxes and insurance?

No. APR includes only the interest rate and mandatory fees charged by the lender. Property taxes, homeowners insurance, HOA fees, and other costs are separate and are not part of the APR.

What if I pay off my loan early — do I save money?

Yes. If you pay off the loan before the full term ends, you will pay less interest than the APR predicts, because you are not paying interest for the entire period. However, some loans charge prepayment penalties, so check your loan agreement before you pay early.
