Unless you plan to repay your credit card in full each month, you'll need to pay interest on the amount you owe.

The APR of a credit card is a direct measure of the cost of using that credit card.

APR stands for the Annual Percentage Rate and includes important factors such as:

- the interest rate you must pay
- how you repay the loan
- the length of the loan agreement
- frequency and timing of installment payments
- amount of each payment
- certain fees associated with the loan

The APR is a good way to compare the cost of various credit cards.

Normally the lower the APR the less interest you will have to pay on your outstanding balance.

Credit cards are always advertised with a 'typical APR' which is the normal rate that you can expect from the card when any promotional or introductory rates expire.

Some credit card providers advertise various APR rates that people may receive depending on the credit card providers assessment of the credit worthiness of the applicant.

The interest rate may vary over time and you should check your monthly statements as they will tell you what the current interest rate is for your card.
