How the debt snowball calculator works

The calculator keeps your total monthly debt budget steady. It pays minimums on every debt, sends extra money to the smallest balance, then rolls that freed-up payment into the next balance after each payoff.

Why people use the snowball method

Paying off the smallest debt first may not always be mathematically optimal, but it can make progress easier to feel. That momentum can matter if you have several debts and need a plan that is simple to follow.

Compare snowball with avalanche

Use the method toggle in the calculator to compare against the debt avalanche method. Avalanche focuses on the highest APR first, while snowball focuses on the smallest balance first. For a broader plan, use the debt payoff calculator.

Debt snowball questions

What is the debt snowball method?

The debt snowball method pays minimums on every debt, then sends all extra money to the smallest balance first. After that debt is gone, its payment rolls into the next smallest balance.

Does the debt snowball save the most interest?

Not always. The avalanche method usually saves more interest because it targets the highest APR first. Snowball can still work well because it creates faster wins.

What debts should I include?

Include unsecured debts such as credit cards, personal loans, medical bills, and store cards. Keep secured debts like mortgages or auto loans separate unless you are intentionally planning to accelerate them too.

Can I switch from snowball to avalanche?

Yes. Use the method toggle to compare both strategies. If motivation is fading, snowball may help. If interest savings matter most, avalanche may be better.
