The debt snowball method, popularized by Dave Ramsey, focuses on paying off debts from the smallest balance to the largest. As each small debt is eliminated, its minimum payment rolls into the next debt — creating a "snowball" effect.
The debt avalanche method is the mathematically optimal approach — it targets the highest interest rate debt first, minimizing total interest paid. Both methods are effective; the best one is the one you stick with.
Step 1: Enter each debt with its current balance, annual interest rate, and minimum monthly payment.
Step 2: Enter any extra amount you can pay toward debt each month beyond the minimums.
Step 3: Click Calculate to compare the snowball, avalanche, and minimum-only strategies side by side.
What Is the Debt Snowball Method?
The debt snowball method is a debt reduction strategy where you list all debts from smallest balance to largest. You make minimum payments on everything except the smallest debt, which receives all available extra payment.
The method was popularized by personal finance author Dave Ramsey. Research from the Harvard Business Review has shown that the psychological boost from quickly eliminating individual debts keeps people motivated.
Debt Snowball vs Debt Avalanche
The debt avalanche method is the mathematical counterpart to the snowball. Instead of targeting the smallest balance, you attack the debt with the highest interest rate first.
In practice, the difference in total interest is often smaller than people expect. The snowball method typically costs a few hundred dollars more in interest but provides faster wins that sustain motivation.
The Power of Extra Payments
Even a modest extra payment of $50 to $200 per month can dramatically reduce your payoff timeline.
Sources of extra payment include reducing discretionary spending, selling unused items, freelance income, or redirecting raises and bonuses.
Frequently Asked Questions About the Debt Snowball Calculator
Both the snowball and avalanche methods pay off debt in the same timeframe when extra payments are equal — the total payoff timeline is identical if all debts have the same interest rate.
Most financial advisors suggest excluding your mortgage from the debt snowball and focusing on consumer debts like credit cards, personal loans, car loans, and student loans.
Even without extra payments, the snowball and avalanche methods still help because as each debt is paid off, its minimum payment rolls into the next debt.
