Interest rate

Simply put, an interest rate is the price a lender charges for loaning money. On credit cards, interest rates are a little trickier, because lenders set multiple interest rates. For example, you may have a low, teaser (introductory) rate when you open an account, followed by a higher standard rate for purchases, which turns into a penalty rate if you pay late. So you may end up owing a balance to a credit card company with multiple interest rates. Interest rates on credit cards are expressed in a standardized way so consumers can more easily compare cards. That standard way is known as the APR, which stands for annual percentage rate.
