Debt Snowball Calculator
This free debt snowball calculator shows how fast you can become debt-free. Add each debt's balance, interest rate, and minimum payment, plus any extra you can pay each month, and it lists your payoff order (smallest balance first), your debt-free date, months to payoff, and total interest paid.
How the debt snowball works
The debt snowball method pays your debts from smallest balance to largest, regardless of interest rate. You pay the minimum on every debt, then throw every extra dollar at the smallest one. When it is gone, its payment rolls onto the next smallest, so your payments grow like a snowball. The wins come fast, which keeps you motivated.
Snowball vs avalanche
The snowball is about motivation; the avalanche method pays the highest interest rate first and saves the most money. If you have been discouraged before, the snowball usually wins because you actually finish it. If saving every dollar of interest matters most, use avalanche.

Frequently asked questions
Is the debt snowball calculator free?
Yes. It is completely free, runs in your browser, and needs no email or account. Your numbers never leave your device.
What counts as the minimum payment?
Enter the minimum monthly payment your lender requires for each debt. The calculator pays every minimum, then adds your extra to the smallest balance.
Does it include interest?
Yes. It adds monthly interest based on each debt's APR, so your payoff date and total interest are realistic estimates.
Snowball or avalanche - which is faster?
Avalanche pays slightly less total interest, but the snowball is usually finished more often because the early wins keep you going. Both beat paying only minimums.
