Debt Avalanche vs. Snowball Calculator
Enter your debts, set an extra monthly payment, and see which repayment strategy saves you more, with a real month-by-month simulation.
Your debts
Extra monthly payment
The amount you can put toward debt each month on top of your minimum payments. Even $50 makes a real difference.
Strategy comparison
Which strategy should you choose?
Debt avalanche: pay the debt with the highest interest rate first while making minimum payments on everything else. When it's cleared, roll its payment into the next-highest rate. This keeps total interest as low as possible.
Debt snowball: pay the smallest balance first. You clear accounts sooner, and those early wins help many people stay motivated. The trade-off is usually paying a bit more interest.
The best strategy is the one you'll stick with. Learn more in a practical plan for paying down debt.
This simulation assumes minimum payments are made as entered, interest compounds monthly, and rates stay the same. It does not account for new borrowing, missed payments, or fees. Results are estimates for educational purposes only.
