How to Compare Credit Card Interest Rates
Quick Answer
Credit cards typically have different APRs for different uses, and some provide promotional financing options to new cardholders. As a result, it's important to shop around and compare rates based on how you plan to use your new credit card.

Credit card interest rates impact how much you pay to carry credit card debt. While you can avoid interest by paying your balance in full every month, it's still important to consider each card's interest rates before you apply.
Here's what to know about how credit card interest rates work and how to compare them.
Understanding How Interest Rates Work
As with other borrowing options, credit card interest rates are expressed in the form of an annual percentage rate (APR). When it comes to installment loans, such as personal loans and mortgages, the APR can be higher than the interest rate because a loan APR incorporates fees and other finance charges. With credit cards, however, the interest rate and APR are the same.
It's also important to note that credit cards typically offer variable interest rates, which means that after you open your account, your APR can fluctuate based on market benchmark interest rates.
A small number of credit cards offer fixed rates, in which case your rate will be the same as long as your account remains open.
Types of Credit Card Interest Rates
Credit cards typically have multiple APRs that apply to certain uses. Here's a quick summary of each:
- Purchase APR: The rate of interest that you pay on purchases you make with your card. Credit cards typically offer a grace period on purchases, which means that you won't incur interest on your balance as long as you pay it off in full each month by your due date.
- Balance transfer APR: The rate of interest that you pay on balance transfers. It's typically the same as the purchase APR, but there's no grace period.
- Intro APR: Many credit cards offer intro APRs on purchases, balance transfers or both for a set period of time. In most cases, the intro APR is 0%, but some cards may simply offer lower rates during this period.
- Cash advance APR: This is the rate of interest that you pay on cash advances. It's typically higher than the purchase and balance transfer APR, and there's no grace period.
- Penalty APR: The rate of interest you pay if you miss a payment by 60 days or more. It's usually the highest interest rate on a credit card, and it may remain in effect for six months or longer.
