A "finance charge" is essentially the price you must pay for using someone else's money. When it comes to credit cards, the term typically refers to the interest you pay on balances. Credit cards can, and often do, charge an array of fees, but most of those don't count as finance charges.
What is a finance charge on a credit card?
When you put a purchase on a credit card, you are borrowing money from the card issuer. The issuer pays the merchant for the purchase, and then you pay the money back to the issuer. In the language of the banking industry, the issuer is "financing" your purchase.
When you pay your credit card bill in full every month, you have a so-called grace period in effect, so you're able to get that financing at no additional charge to you. No finance charges, in other words. But if you don't pay in full, and you roll a portion of your balance over from one month to the next, there is no grace period. You will be charged for that financing, in the form of interest. Finance charges = interest.
Credit cards typically charge high interest and are one of the most expensive forms of financing. The average APR on credit card accounts that incurred interest was 21.52% as of February 2026, according to the Federal Reserve. That just underscores the value of paying in full each month and maintaining your grace period.
Types of credit card finance charges
The interest rate you pay on credit card balances is referred to as the annual percentage rate, or APR. Some cards charge the same rate on all kinds of activity; others charge different rates depending on the nature of the balance. Most common is the purchase APR, which is, obviously, the rate charged on purchases. But you might be charged a higher (or lower) rate for balance transfers or cash advances.
Many cards offer promotional 0% APR periods for purchases and/or balance transfers, in which case there are no finance charges at all on those transactions during the introductory period. Many cards also charge a penalty APR — a higher rate that kicks in if you pay late, miss a payment or violate some other term of the credit card agreeement.
What isn't a finance charge on a credit card
A key point to understand about finance charges on credit cards is that they represent the ongoing cost of borrowing money. As long as you owe the money, finance charges will accumulate. When you pay it off, the charges stop. So not all charges imposed by your credit card count as finance charges:
- An annual fee, for example, is not a finance charge. It's not the cost of borrowing money. It's the cost of carrying the card — a membership fee, in effect — and you pay it regardless of whether or how much you use the card.
- Foreign transaction fees are a surcharge on purchases made outside the U.S. They're not strictly a cost of borrowing money; they're the cost of processing a transaction across international borders. They are imposed even if you have a grace period going.
- A late fee is not a finance charge. It's a penalty for violating the terms of your credit agreement.
- Balance transfer fees and cash advance fees are a little more iffy. Although they are closely tied to the act of borrowing, they can be thought of more like transaction fees: You pay a certain amount of money upfront for the card issuer to provide a service in the first place, then you pay finance charges on the actual money you borrow.
