How to use the calculator

Enter your opening balance, card interest rate and your monthly repayments and the calculator will prepare a table showing how your balance will reduce over time.

Opening balance - enter the current amount owing on your credit card. Don't add a dollar sign or a comma. The opening balance must be between $0.00 and $99,999.99

Interest rate - enter the standard purchase rate of your credit card. Don't include the percent symbol (%). The interest rate must be between 0.00% and 99.99%. If your card has a balance transfer rate, it's best to use the (higher) standard rate as balance transfer deals are usually only temporary

Monthly repayments - enter the amount you plan to pay off your credit card each month. Don't add a dollar sign or comma. The monthly repayments must be between $0.00 and $9,999.99. Try adjusting this figure to see how it affects the total time required to pay off your balance.
