This calculator assumes fixed interest rates and consistent payments, which is a simplification of real-world debt. Read our full debt snowball vs. avalanche guide for context, and see our disclaimer.
How this calculator works
This tool simulates paying down your debts month by month under two strategies: the avalanche method (extra payments go to the highest-interest debt first) and the snowball method (extra payments go to the smallest balance first). As each debt is paid off, its minimum payment is rolled into the next target debt under both methods.
Read our full debt snowball vs. avalanche guide for the reasoning behind each approach and which might fit you better.
