Debt Payoff Calculator

Avalanche vs Snowball: which is better?

The avalanche method pays off debts in order of highest interest rate first. This saves you the most money in total interest paid and is mathematically optimal. The snowball method pays off debts in order of smallest balance first, giving you quick wins that build momentum and motivation.

Research shows the snowball method has a higher success rate because the psychological boost of paying off a debt keeps people motivated. But the avalanche method can save thousands in interest. Use this calculator to compare both side by side.

How debt payoff works

You make minimum payments on all debts, then put any extra money toward one target debt at a time (either highest rate or smallest balance). When that debt is paid off, you roll that payment to the next target — this is called "debt snowballing" your payments. The calculator shows the exact month-by-month schedule for both methods.
