An APR of 11% or less on purchases
The annual percentage rate (APR), or interest you pay on balances, must appear in big type. You aren't guaranteed this APR. It will depend on your credit history.

The box will also say whether there's an introductory rate and how long it'll last. Today's average APR is 11.32%; with a credit score of 720, you should get 10% or less.

Note: Most APRs are variable, meaning they change with the prime rate.
