Build a payoff plan using the snowball or avalanche method. Free debt snowball calculator showing your debt-free date and total interest.
About the Debt Snowball Calculator
The debt snowball and avalanche methods are two proven strategies for clearing multiple debts. This free debt snowball calculator lets you list each debt with its balance, interest rate and minimum payment, add the extra you can afford, and see an ordered payoff plan with your debt-free date and total interest paid.
The snowball method attacks the smallest balance first for quick psychological wins, then rolls its freed-up payment onto the next debt — a growing 'snowball'. The avalanche method targets the highest interest rate first, which minimises total interest. The calculator supports both so you can compare the motivation of snowball against the savings of avalanche.
Anyone juggling several loans or credit cards uses this to replace anxiety with a concrete plan. All figures stay in your browser — nothing about your debts is uploaded. There is no signup.

Frequently Asked Questions
What is the debt snowball method?
You pay minimums on every debt and throw all spare money at the smallest balance first. Once it is cleared, you roll its payment onto the next-smallest debt, and so on. The quick early wins keep you motivated, even though it may not minimise interest.
What is the difference between snowball and avalanche?
Snowball orders debts by balance, smallest first, for motivation. Avalanche orders them by interest rate, highest first, to minimise total interest. Avalanche usually costs less overall, but snowball's fast early wins help many people stick with the plan.
How does paying extra speed up debt payoff?
Extra payments go straight to principal on the targeted debt, so it clears faster. Then its whole payment — minimum plus extra — moves to the next debt, accelerating each subsequent payoff. This rolling effect is what makes both methods so effective.
Which method saves the most money?
The avalanche method, because it eliminates the highest-interest debt first and therefore accrues the least total interest. The difference is largest when your debts have very different rates — for example a 36% credit card alongside a 10% personal loan.
Should I pay minimums on all debts while doing this?
Yes, always. Both methods require paying at least the minimum on every debt to avoid penalties and credit damage; only the extra money is concentrated on the target debt. Missing a minimum on another debt would undo the plan's benefit.
