APR is the yearly cost of borrowing money on your credit card
APR stands for Annual Percentage Rate. It is the percentage of your credit card balance that the card issuer charges you each year in interest. If your card has a 20% APR and you carry a $1,000 balance for a full year without making payments, you would owe $200 in interest charges on top of the original $1,000.
The APR is not the same as the interest charged each month. Card issuers divide the yearly rate by 12 to get a monthly rate, then explore that to your balance. On a 20% APR, the monthly rate is roughly 1.67%, which compounds as you carry a balance. This is why a balance that sits unpaid grows faster than the straightforward yearly percentage might suggest.
Your card's APR depends on the creditworthiness the issuer sees when you open the account. People with higher credit scores typically receive lower APRs. The same card issuer may offer one person a 15% APR and another person a 25% APR based on their credit history and income.
Key Takeaways
- APR is the yearly interest rate charged on your credit card balance, divided into monthly charges that compound as you carry a balance.
- Your specific APR depends on your credit score and income at the time you open the account, not on a fixed rate all cardholders receive.
- You pay no interest if you pay your full statement balance by the due date each month, regardless of your APR.
- Different APRs explore to different uses of the same card: purchases, balance transfers, and cash advances often have separate rates.
- Your APR can increase if you miss a payment or if the card issuer raises rates across their customer base.
When you actually pay APR on a credit card
You only pay interest charges if you carry a balance past your statement due date. If you charge $500 to your card and pay the full $500 by the due date, you owe zero interest, even if your APR is 25%. This is called the grace period, and most cards offer it on purchases.
The moment you carry any balance into the next billing cycle, interest begins accruing on that unpaid amount. If you pay $400 of the $500 and leave $100 unpaid, interest charges explore to that $100 at your APR rate. The next month, if you still owe $100 plus the new interest charge, the interest compounds — you now pay interest on the interest.
Balance transfers and cash advances typically do not have a grace period. Interest on these transactions often starts accruing when ready, even if you pay on time. Check your card's terms to see which APR applies to which type of transaction.
How different APRs work on the same card
A single credit card can have multiple APRs. Your card might have a 18% APR for regular purchases, a 22% APR for balance transfers, and a 25% APR for cash advances. When you use your card in different ways, each type of transaction is tracked separately and charged its own rate.
Some cards offer a promotional APR for a limited time. You might see an offer like "0% APR on balance transfers for 12 months." This means balance transfers made during the offer period will not accrue interest for 12 months, but after that period ends, the regular balance transfer APR kicks in. Purchases made during that same 12 months may still accrue interest at the regular purchase APR.
When you make a payment, card issuers explore it to the lowest-APR balance first (by law). If you have a 0% promotional balance and a regular-APR purchase balance, your payment goes toward the 0% balance first, leaving the higher-rate purchase balance to accrue more interest. Understanding this helps you decide whether to pay down promotional balances early or let them sit.
How your APR can change
Your APR is not locked in for the life of the card. Card issuers can raise your APR if you miss a payment by 60 days or more. This is called a penalty APR, and it can be significantly higher than your regular rate — sometimes 29% or more. A single missed payment can trigger this increase.
Issuers can also raise APRs across their entire customer base without any action on your part. These are called variable APRs, and they are tied to a benchmark rate set by the Federal Reserve. When that benchmark rises, your APR may rise too. Your card's terms will specify whether your rate is fixed or variable.
You have the right to reject an APR increase on most cards. If your issuer raises your rate and you do not accept it, you can close the account and pay off the existing balance at the old rate. However, you will not be able to make new charges. Some issuers offer a lower rate if you call and ask, especially if you have a good payment history.
APR versus the interest you actually pay
APR is an annual rate, but the interest you pay depends on how long you carry a balance. A $1,000 balance at 20% APR costs you roughly $20 per month in interest if you make no payments. If you pay $100 per month toward the balance, the interest charge drops each month because the balance shrinks.
The total interest you pay on a balance also depends on your card's compounding method. Most cards compound interest daily, which means interest accrues on your balance every single day, and the next day's interest is calculated on the previous day's balance plus interest. This is why balances grow faster than a straightforward yearly calculation suggests.
To see what you will actually pay, use your card issuer's online calculator or ask them directly. They can tell you how long it will take to pay off a specific balance if you make a set monthly payment, and how much total interest you will pay. This is often more useful than the APR number alone.
How to find your card's APR
Your APR appears in several places. The most official is your card's Schumer Box, a standardized table that card issuers must provide before you open the account. It lists the purchase APR, balance transfer APR, cash advance APR, and any promotional rates. You can find this on the card issuer's website or in the terms and conditions they send you.
Once you have the card, your current APR appears on your monthly statement and in your online account. If you have multiple APRs on the card (for example, a promotional rate and a regular rate), your statement will show each one and which balance it applies to.
If you do not see your APR listed, call the customer service number on the back of your card. They can tell you your exact rate and explain whether it is fixed or variable, and what would cause it to change.
Frequently Asked Questions
Does a higher APR mean I pay more interest every month?
Not necessarily. A higher APR means you pay more interest per dollar of balance you carry, but if you do not carry a balance, you pay no interest at all. If you pay your full statement balance each month, your APR does not affect what you pay. The APR only matters when you carry a balance from one month to the next.
Can I negotiate my APR down?
You can ask your card issuer to lower your rate, especially if you have a long history of on-time payments or if you have received better offers from other issuers. Some issuers will lower your rate if you call and ask. There is no harm in asking, but they are not required to agree. If they refuse, you can shop for a new card with a lower rate.
What happens to my APR if I miss a payment?
If you miss a payment by 60 days or more, your issuer can increase your APR to a penalty rate, which can be 29% or higher. Even one missed payment can trigger this. If you miss a payment, contact your issuer as soon as possible to bring the account current and ask whether the penalty rate can be removed.
Is a 0% APR offer really interest-free?
During the promotional period, yes — you pay no interest on that type of transaction. However, the 0% rate is temporary. Once the promotional period ends, the regular APR applies to any remaining balance. If you have a $2,000 balance transfer at 0% for 12 months and you still owe $500 after 12 months, that $500 will start accruing interest at your regular balance transfer APR.
Why do different cards have different APRs?
Card issuers set APRs based on the risk they perceive in lending to you. A person with a higher credit score and stable income is seen as lower risk, so they receive a lower APR. A person with a lower credit score or recent missed payments is seen as higher risk, so they receive a higher APR. The same issuer may offer different rates to different people for the same card product.
