About the Debt Payoff Calculator

very high volume / year-round search with debt management intent

The Debt Payoff Calculator is a free online financial tool designed to help you calculate how long it will take to pay off your debt and how much interest you will pay, with support for multiple payment frequencies and debt type presets. It includes a built-in accelerator comparison that shows the impact of adding extra payments to your regular minimum payment. Pair it with our Credit Card Calculator for credit-card-specific daily-rate analysis or our Loan Calculator for amortized loan comparisons.

Select a debt type (credit card, personal loan, auto loan, student loan, home equity, medical debt, or other) to auto-fill typical interest rates, or enter your own. Choose monthly, bi-weekly, or weekly payment frequency. Enter your current balance, APR, minimum payment, and any extra payment you plan to make. The tool instantly shows your payoff timeline, total interest, total paid, and how much interest an extra payment saves. A side-by-side accelerator comparison table and a full period-by-period payoff schedule provide complete transparency.

Formulas & Mathematical Theory

Debt Payoff Time (Fixed Payment)

n=log⁡(MM−B×r)log⁡(1+r)n = \frac{\log\left(\frac{M}{M - B \times r}\right)}{\log(1 + r)}

Where B is the current balance, M is the fixed monthly payment, and r is the monthly interest rate. Solves for the number of months to full payoff.

Total Interest Paid

Total Interest=(M×n)−B\text{Total Interest} = (M \times n) - B

The total interest cost is the sum of all payments minus the original balance borrowed.
