Debt Payoff Calculator

Estimate how long it may take to clear a debt using your balance, APR, monthly payment and optional extra payment.

Use this debt payoff calculator when you want a clearer timeline for a loan, credit card balance or another debt that still accrues interest. It helps you turn a rough plan into a month-based estimate before you change your payment routine.

Enter the current balance, annual interest rate, monthly payment and any extra amount you can add each month. The result shows the estimated payoff time, target month, total interest and the full amount paid under that plan.

Keep the same currency unit across the balance, monthly payment and extra payment.

Quick noteYour result will appear here as soon as the payment plan is viable.

Use clear inputs to get a more useful result.

The calculator runs a month-by-month payoff estimate based on the annual rate you enter. If you add an extra monthly amount, it also compares that faster plan with the base payment to show how much time and interest may be saved. Treat the result as a planning estimate, not a lender statement. Fees, variable rates, new charges and lender-specific rules can change the real payoff path.
