Interest Charges and Fees

Get to know your Annual Percentage Rate (APR)
Credit companies charge a fee in exchange for letting you carry balances. These are called Interest Charges. You can avoid a Interest Charge on purchases if you pay your balance in full each month. However, if you pay less than the full balance, a Interest Charge will be added to your account. If you carry a balance from month to month, Interest Charges will add up.

APR is the interest rate, calculated on a yearly basis, which you pay on balances. If you carry a balance, the APR is the best indicator of what credit costs. The higher the APR, the more you will pay. Some credit card companies offer lower introductory rates for a limited period of time. Afterwards, these rates usually go up. To calculate the rate each month, divide the APR by 12. For example, if the APR is 18%, the monthly interest rate on carrying a balance is 1.5%.

Your APR may be tied to a specific rate of interest, such as the Prime Rate. This means your interest rate is "variable"—it could go up or down over time. A non-variable APR doesn't change the way a variable does. However, with advance notice from the card company or if you default on your payments, non-variable rates may still change at some point as permitted by law.

Your rate may also change as described in your Card Agreement or upon written notice from the company.
