It is always best to pay off your credit card balance in full by the due date indicated on your statement. If you can't, you can still reduce the amount of interest you will have to pay. The credit card payment calculator compares 3 different payment options to pay off your credit card balance.
What if you only make the minimum payment each month?
What if you make the minimum payment plus an additional amount each month?
What if you pay a fixed amount each month?
The credit card calculator assumes that you are not using your credit card while you are paying off the balance.
