What is Debt Payoff Calculator?
A debt payoff calculator compares the two classic debt-repayment strategies - snowball and avalanche - using your real balances, interest rates, and minimum payments. It simulates both plans month by month to show the total payoff time, the payoff date, the interest you will pay, and the order in which each debt gets cleared. Because both strategies keep your monthly payment fixed and only reorder the debts, the choice between quick wins and maximum savings can change your total interest by hundreds or thousands. This free tool runs entirely in your browser - paste your debts, add an extra monthly payment, and see which path to debt freedom fits you best.
