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

APR stands for Annual Percentage Rate. It tells you what percentage of the money you borrow will cost you over one year. If you borrow $1,000 at 5% APR, the cost of that loan for one year is $50 — before you make any payments back.

APR includes not just the interest rate itself, but also fees the lender charges: origination fees, closing costs, or other charges bundled into the loan. That is why APR is almost always higher than the interest rate alone. A credit card might advertise a 15% interest rate, but the APR could be 15.9% once fees are factored in.

The reason lenders show you APR is so you can compare loans fairly. Two lenders might quote different interest rates and different fees — APR puts them on the same scale, so you can see which one actually costs less.

Key Takeaways

  • APR includes both the interest rate and any fees the lender charges, so it is always the true yearly cost of borrowing.
  • Two loans with the same interest rate can have different APRs if one lender charges more in fees.
  • APR makes it possible to compare loans from different lenders using a single number.
  • The higher the APR, the more you pay back over the life of the loan, assuming you make regular payments.
  • Credit cards, mortgages, auto loans, and personal loans all have APRs, but they work differently depending on the loan type.

How APR differs from interest rate

The interest rate is the percentage of the loan amount that the lender charges you for the use of their money. The APR is that interest rate plus any other costs attached to the loan. If a mortgage has a 4% interest rate and $2,000 in closing costs on a $300,000 loan, the APR will be higher than 4%.

On a credit card, the difference is smaller but still real. The card issuer charges interest on your balance, but may also charge an annual fee. That fee gets rolled into the APR calculation. A card with no annual fee might have an APR of 18%, while an identical card with a $95 annual fee might show 18.5% APR.

For short-term loans, the difference between interest rate and APR matters less. For long-term loans like mortgages, it matters much more, because fees get spread across 30 years and add up significantly.

How APR is calculated

Lenders calculate APR by taking the total cost of the loan (interest plus fees) and expressing it as a yearly percentage of the amount you borrowed. The formula accounts for the fact that you pay the loan back over time, not all at once.

You do not need to calculate APR yourself — lenders are required to disclose it to you before you sign. On a mortgage, it appears on the Loan Estimate form. On a credit card, it is in the card's terms and conditions. On a personal loan or auto loan, it is in the loan agreement.

What matters is that you read the APR before you commit. A loan with a lower APR will cost you less money over time than one with a higher APR, all else being equal.

Fixed APR versus variable APR

A fixed APR stays the same for the entire life of the loan. If you take out a mortgage at 4% fixed APR, your rate will not change even if market rates rise or fall. This makes your monthly payment predictable.

A variable APR can change over time, usually tied to a market index like the prime rate. Credit cards almost always have variable APR. A mortgage might start with a fixed rate for five or seven years, then switch to variable. When the APR changes, your monthly payment changes too.

Variable APR is riskier because you cannot predict what you will owe in the future. If rates rise sharply, your payment could jump significantly. Fixed APR costs you certainty — you pay a slightly higher rate in exchange for knowing exactly what your payment will be.

How APR affects your total cost

The higher the APR, the more you pay back in total. On a $200,000 mortgage at 4% APR over 30 years, you pay roughly $143,000 in interest. At 5% APR, you pay roughly $186,000 in interest — an extra $43,000 for a single percentage point difference.

On a credit card, APR matters less if you pay your balance in full each month, because you do not owe any interest. But if you carry a balance, APR determines how much interest charges pile up. A $5,000 balance at 18% APR costs you about $75 per month in interest alone if you make no payments.

For short-term loans like payday loans or personal loans, APR can be extremely high — sometimes 300% or more. That means the cost of borrowing quickly becomes much larger than the amount you borrowed.

Where to find APR information

Lenders must disclose APR before you sign any loan documents. For mortgages, the Loan Estimate form shows the APR clearly. For auto loans, it is in the loan agreement. For credit cards, check the card's terms and conditions or the issuer's website.

When shopping for loans, always ask for the APR, not just the interest rate. If a lender quotes only an interest rate, ask them to give you the APR in writing. This is your right under federal law.

Online loan marketplaces and comparison sites often list APR ranges for different loan types. These ranges vary by lender, credit score, and loan amount, so the APR you actually receive may differ from what you see advertised.

APR on different types of loans

Mortgages typically have the lowest APRs because they are secured by the house itself — if you do not pay, the lender can take the house. APRs on mortgages usually range from 3% to 8%, depending on market conditions and your credit.

Auto loans come next, usually between 4% and 10%, because the car secures the loan. Credit cards have much higher APRs, typically 15% to 25%, because they are unsecured — the lender has no collateral if you do not pay. Personal loans fall in between, usually 6% to 36%, depending on the lender and your credit score.

Payday loans and other short-term loans can have APRs of 300% or higher. These loans are designed to be repaid quickly, but the annualized rate is extremely steep. If you borrow $500 for two weeks at a typical payday loan cost of $75, that works out to an APR of around 390%.

Frequently Asked Questions

Is a lower APR always better?

Yes. A lower APR means you pay less money over the life of the loan. When comparing two loans, choose the one with the lower APR, assuming the other terms (loan length, payment schedule) are the same. A loan with a lower APR but a longer term might cost more overall, so compare total cost, not just the rate.

Can I negotiate my APR?

On mortgages and auto loans, yes — the APR is often negotiable, especially if you have good credit or a large down payment. On credit cards, your APR is usually set by the issuer based on your credit score, but you can ask for a lower rate if your credit has improved. On personal loans, some lenders negotiate, others do not.

What is a good APR?

It depends on the loan type and current market conditions. For mortgages, anything under 7% is generally considered good. For auto loans, under 6% is good. For credit cards, under 15% is excellent. Your actual APR depends on your credit score, income, and the lender's policies.

Does APR include the principal I have to pay back?

No. APR is only the cost of borrowing. The principal is the amount you borrowed. If you borrow $10,000 at 5% APR, you owe the $10,000 back plus 5% of that amount per year in interest and fees. Your total payment is principal plus APR cost.

Why do credit card APRs change?

Credit card APRs are almost always variable, tied to the prime rate set by the Federal Reserve. When the Fed raises or lowers rates, card issuers adjust their APRs accordingly. Your individual APR can also change if you miss payments or if the issuer reviews your account and decides to adjust your rate.
