Frequently Asked Questions
How do I calculate how long it takes to pay off a debt?
Enter your current balance, annual interest rate, and monthly payment. The calculator shows the months to payoff, total interest, and payoff date.
Why does paying $50 more per month matter so much?
Extra payments reduce the principal faster, which means less interest accrues each month. Small extra payments can cut years off the payoff timeline.
What does total interest paid mean?
It is the cumulative interest cost over the life of the debt - the total amount you pay above the original balance.
What if my payment is too low?
If your monthly payment is less than or equal to the monthly interest charge, the debt will never be paid off. The calculator shows a warning in this case.
Can I use this for credit card debt?
Yes. Enter your credit card balance, annual percentage rate (APR), and minimum or planned monthly payment to see the payoff timeline.
Is the debt payoff calculator free?
Yes. Completely free with no sign-up required.
