How to use Credit Card Calculator

Provide the balance and payment plan, and the calculator will estimate how long the card debt may stay with you if you keep paying at that pace.

What this calculator is for

This calculator is for repayment planning and interest-awareness when revolving debt is costing more than it first appears. It helps show why minimum-style payments can stretch a balance out for much longer than many borrowers expect.

Tips

Use the actual card APR, not a rounded memory of it, because high revolving rates change payoff time quickly.
If you are still adding charges to the card, the real payoff timeline can be longer than the estimate shown here.
