Debt Snowball & Avalanche Calculator

Enter your debts, choose a payoff strategy, and see exactly how long it takes and how much interest you'll save.

How minimum payments are calculated: for credit cards and lines of credit, we use the minimum payment amount you enter, and let it decline each month as your balance drops — the same way your card issuer recalculates it. It never drops below $25/mo, and we override what you enter only if it wouldn't cover that month's interest or falls below that $25 floor. Loans always use the fixed payment you enter. For accurate results, enter the real balance, interest rate, and minimum payment from your latest statement — the simulation is only as accurate as the numbers you give it.
