Debt Payoff Calculator
Enter your debts and see how snowball (smallest balance first) and avalanche (highest interest first) strategies compare. Add extra payments to see how much faster you can become debt-free.
Your Debts
Amount above minimums you can put toward debt each month.
How We Calculate
Snowball method: Pay minimums on all debts, then put extra money toward the smallest balance. When that's paid off, roll its payment into the next smallest. Harvard research shows this method has higher completion rates due to the psychological boost of quick wins.
Avalanche method: Pay minimums on all debts, then put extra money toward the highest-interest debt. Mathematically optimal — saves the most in interest over time.
Both methods assume you continue making minimum payments on all debts simultaneously and direct any extra payment toward the target debt.
