The Difference between Credit Card Interest Rates and APR

Before you choose a credit card, you’ll first need to understand the distinction between interest rates and annual percentage rates, or APRs. Consumers often conflate these two numbers, which ultimately works to their detriment. Although interest rates and APRs are both expressions of the same thing fundamentally, there is usually a substantial disparity between the two figures that all cardholders should be aware of. Read on to learn more about how interest rates differ from APRs.

Interest Rate vs. APR

Both interest rates and annual percentage rates are numerical expressions of the cost of borrowing. In other words, they express on an annual basis how much the borrower will pay for the convenience of borrowing. Credit card interest rates can be computed in a number of different ways and do not account for any borrowing costs other than interest expenses. Interest rates can be difficult to compare among various cards because every card issuer could potentially compute the number in a different way. Occasionally, card issuers will advertise an interest rate that is deceptively low because it fails to include the total cost of borrowing.

Annual Percentage Rate

Annual percentage rates, or APRs, include the cost of interest but also factor in all other costs of borrowing. Additional costs of borrowing might include finance charges, fees, penalties, etc. In this way, APR tends to be a more accurate reflection of the costs associated with a particular credit card. Moreover, according to federal law, all lenders must compute credit card APRs in the same way. The Truth in Lending Act specifies a certain formula for computing APR that all credit card issuers use. Because of this added degree of uniformity, APRs are a much more reliable and accurate way to compare different credit cards.

By law, credit card issuers must include the APR for the card in bold in your cardholder agreement. With most credit cards, the agreement will specify more than one APR. We’ve outlined the most common kinds of credit card APRs below.

  • Purchase APR. The interest rate you will pay on regular purchases made with your credit card.
  • Balance transfer APR. The rate you will pay on balances that you transfer from other credit cards.
  • Cash advance APR. The rate you pay for cash loans on your credit card. This is usually the highest of all APRs.
  • Penalty APR (default APR). The rate you will pay if you make a late payment. Your cardholder agreement will specify how many late payments are allowed before the penalty APR kicks in.
