About This Calculator
This calculator estimates how long it will take to pay off a debt balance based on your interest rate and monthly payment, and shows how an extra payment can change that timeline.
It works for most types of revolving or fixed-rate debt. For a loan with a specific fixed term, such as an auto loan or mortgage, use the dedicated calculators below for a more precise estimate.
