This calculator will show you how much interest you will end up paying if you make only the minimum required payment on your credit card bill. It will also tell you how many minimum payments you will make before your balance is paid off (up to a maximum of 600 payments). Note: When entering numbers into the data fields only use numbers and applicable decimal points. Entering commas, dollar signs, or any other non-numeric characters will cause an error. Also please note that this calculator has been tested to work with Internet Explorer 3.01 and Netscape Navigator 3.01 web browsers. However, both must have the JavaScript option turned on.
