What is the debt snowball method?

You list all debts from smallest to largest balance. Each month you pay the minimum on every debt, then apply any extra money to the smallest balance. When that debt is eliminated, its full payment — minimum plus extra — rolls to the next smallest debt. The "snowball" grows with each payoff, accelerating your progress.

How is the debt avalanche different from the snowball?

The avalanche ranks debts by interest rate, highest first. Extra money targets the most expensive debt first. This minimizes total interest paid. The snowball targets the smallest balance first, which usually costs a bit more in interest but delivers faster early wins that keep you motivated.

Why does the snowball sometimes cost more in total interest?

If your smallest balance also has a low interest rate, you are paying it down before higher-rate debts compound for longer. The extra interest on those high-rate debts can exceed what you would have paid under the avalanche. The difference is often small and may be worth the psychological benefit.

What if I cannot afford any extra payment?

Set extra payment to zero. The calculator still applies the full snowball roll — when one debt is paid off, its freed minimum rolls to the next debt. Even without extra cash, the snowball effect speeds up payoff versus making only minimums forever.

How many debts can I enter?

Up to 5 debts. For more debts, identify which ones to prioritize first, then re-run the calculator once those are cleared.

Does Dave Ramsey recommend the debt snowball?

Yes. Dave Ramsey popularized the debt snowball as Baby Step 2 of his plan, paying smallest balances first regardless of interest rate. His reasoning is behavioral: quick early wins build momentum and keep people motivated to finish. This calculator follows that smallest-first order and shows the interest trade-off versus the avalanche.

How it works

The snowball method ranks your debts from smallest balance to largest. Every month you pay the minimum on all debts and throw any extra money at the smallest. When that debt is gone its minimum payment rolls into the next smallest, creating a growing "snowball." The avalanche method does the same but targets the highest-rate debt first, minimizing total interest paid.
