Simulate paying off multiple debts smallest-balance-first, the "debt snowball" method.

How It Works

How Debt Snowball Calculator Works

Every debt gets its minimum payment each month, and any extra money you can put toward debt goes entirely to whichever debt has the smallest remaining balance. Once that debt is fully paid off, its payment amount rolls into the next-smallest debt, building momentum — the "snowball" effect the method is named for — month by month until every debt is cleared.

FAQ

Frequently Asked Questions

Why pay off the smallest balance first instead of the highest interest rate?
It's a behavioral strategy rather than a strictly mathematical one — clearing a full debt quickly provides an early, motivating win that keeps people sticking with the plan, even though it usually costs somewhat more in total interest than prioritizing the highest rate first.
How should I enter my debts?
One debt per line, as balance, interest rate, minimum payment — for example "4500,19.99,120" for a $4,500 balance at 19.99% APR with a $120 minimum payment.
