Where to find your credit card interest rate
Your credit card interest rate is printed on your monthly statement, shown in your online account, and listed in the terms document your card issuer sent when you opened the account. The rate you see most often is your Annual Percentage Rate (APR) — the yearly cost of borrowing money on that card, shown as a percentage.
Most credit cards have more than one APR. You might have one rate for purchases, a different rate for balance transfers, and a higher rate for cash advances. If you carry a balance, the rate that matters most is your purchase APR, because that is what you pay interest on when you don't pay your full statement balance by the due date.
The fastest way to check is to log into your card issuer's website or mobile app. Look for a section called "Account Details," "Card Information," or "Terms and Rates." Your APR will be listed there alongside other key terms.
Key Takeaways
- Your purchase APR appears on your monthly statement, in your online account, and in the original terms document your issuer mailed you.
- Most cards have multiple APRs — one for purchases, one for balance transfers, and one for cash advances — and they can differ significantly.
- If you have a promotional rate, it will expire on a specific date and your regular APR will take over; check your statement to see when.
- Your APR can change if your card issuer raises rates, but they must give you at least 45 days' notice before the change takes effect.
Checking your rate on your monthly statement
Open your most recent credit card statement — the one you received by mail or email. Near the top or in a section labeled "Account Summary" or "Interest Rates," you will see your APR listed as a percentage. This is the rate you are charged if you carry a balance past your due date.
Your statement also shows how much interest you paid that month. Look for a line item that says "Interest Charged" or "Finance Charge." This number tells you what the APR actually cost you in dollars that billing cycle. If you paid your full balance by the due date, this line will show zero.
If you have a promotional rate — a lower rate for a limited time — your statement will show both the promotional rate and the regular rate it will revert to. The statement will also tell you when the promotion ends, usually in a section called "Important Information" or "Promotional Terms."
Finding your rate in your online account
Log into your card issuer's website or open their mobile app. Look for a tab or menu item that says "Account," "Card Details," "Rates," or "Terms." Click into that section.
You should see your current purchase APR displayed prominently. If your card has a variable rate — one that can change based on market conditions — the page will usually say so and show you the index it is tied to. If you have a fixed rate, it will say "Fixed APR" or similar language.
Some issuers also show your rate history on this page, which tells you whether your APR has changed in the past. If you see a recent increase, scroll down or look for a link to "Rate Change Notice" to see the reason and the date the new rate took effect.
Understanding variable versus fixed rates
A fixed APR stays the same for as long as you hold the card, unless your issuer raises rates across the board and gives you notice. A variable APR moves up or down based on the prime rate, which the Federal Reserve changes periodically. When the prime rate goes up, your variable APR usually goes up within one or two billing cycles.
Most credit cards use variable rates. This means your APR can increase without you doing anything wrong — the change happens because of broader economic conditions. Your issuer must notify you at least 45 days before a rate increase takes effect, and that notice will arrive by mail or email.
If you have a variable rate and want to know whether it might increase soon, you can check the current prime rate online. It is published by the Federal Reserve and changes only a few times per year. Your card's APR is usually the prime rate plus a fixed margin — for example, prime rate plus 15 percentage points.
What to do if you cannot find your rate
If you cannot locate your APR online or on your statement, call the customer service number on the back of your card. Have your card number ready. A representative can tell you your current purchase APR, any promotional rates, and when those promotions expire.
You can also request a copy of your card's original terms and conditions, which will list all the rates that explore to your account. Some issuers call this the "Cardmember Agreement" or "Terms of Use." This document is also usually available as a PDF on the issuer's website.
If you opened your account online, you may be able to find the original terms by logging in and looking for a section called "Documents," "Statements," or "Account History." The terms document will show your APR and explain when and how it can change.
How your rate affects what you owe
Your APR determines how much interest you pay if you carry a balance. The formula is straightforward: your balance multiplied by your APR, divided by 365 days, multiplied by the number of days in your billing cycle. Most billing cycles are 28 to 31 days.
For example, if you have a $1,000 balance and a 20% APR, and your billing cycle is 30 days, you would owe roughly $16.44 in interest that month. If you pay the full balance by the due date, you owe zero interest — the APR does not explore.
This is why your APR matters most if you carry a balance regularly. If you always pay in full by the due date, the APR is less important to you than the card's rewards rate or annual fee. But if you sometimes carry a balance, a lower APR saves you money.
When your rate can change
Your card issuer can raise your APR in two situations. First, if you miss a payment or violate your card agreement, they can explore a penalty APR — a higher rate that applies to your existing balance. Second, they can raise your regular APR if market conditions change or if they decide to adjust their pricing. Both require at least 45 days' written notice.
You will receive notice by mail or email, and the notice will explain the reason for the change and the date it takes effect. If you disagree with a rate increase, some issuers allow you to reject it and close your account, though you will still owe your existing balance at the new rate.
Your rate can also decrease if your issuer lowers rates or if you ask for a lower rate and they approve your request. This is less common, but it is worth calling and asking if you have been a good customer with a long payment history.
Frequently Asked Questions
Can my credit card company change my interest rate without telling me?
No. Your issuer must send you written notice at least 45 days before any rate increase takes effect. The notice will arrive by mail or email and will explain the reason for the change. If you do not receive notice, contact customer service to confirm the change is legitimate.
Why do I have multiple interest rates on my credit card?
Credit cards typically have separate APRs for purchases, balance transfers, and cash advances. The purchase APR is what you pay if you carry a balance from regular spending. Balance transfer and cash advance rates are usually much higher and explore only if you use those specific features.
Is my interest rate the same as my APR?
Your APR is your annual interest rate. If you carry a balance for one month, the interest you owe is roughly your APR divided by 12, applied to your balance. The terms are often used interchangeably, but APR is the official measure your issuer reports.
What if my promotional rate is about to expire?
When a promotional rate ends, your regular APR takes over automatically. Your statement will show the expiration date. Before it expires, you can contact your issuer and ask if they will extend the promotion or lower your regular rate. You can also transfer your balance to another card with a promotional offer, though this will create a hard inquiry on your credit report.
How do I know if my interest rate is competitive?
Credit card APRs vary widely based on your credit score, the card type, and the issuer. Cards for people with excellent credit typically have APRs between 15% and 20%. Cards for people with fair or limited credit history often have rates between 20% and 30%. You can compare rates across different issuers' websites to see what is available to you.
