How debt payoff timeline works

This calculator simulates month by month debt repayment using your balances, APRs, minimum payments, and any extra monthly payment. It estimates how long repayment may take, how much interest may be paid, and when you may become debt-free under the selected strategy.

InputEffect
BalanceRaises the amount that must be repaid
APRDrives monthly interest cost
Monthly paymentDetermines how fast debt can shrink
Extra paymentCan reduce payoff time and total interest

Avalanche vs snowball

The avalanche strategy sends extra payment to the highest APR debt first, which usually reduces interest cost faster. The snowball strategy sends extra payment to the lowest balance first, which can close smaller accounts sooner.

Why payoff time can be long

Debt payoff can take much longer when APR is high or payments are only slightly above monthly interest. Even a moderate extra payment can materially change the debt-free date in some cases.
