What Is the Debt Snowball Method?

The Debt Snowball strategy orders your debts from the smallest balance to the largest balance, regardless of interest rates. You pay the minimum required payment on every account, while directing all available extra monthly funds toward the smallest debt.

Why People Choose the Snowball Strategy

Behavioral studies show that paying off an entire debt account quickly provides psychological motivation and a sense of progress. Eliminating smaller balances early reduces the total number of open debt accounts, simplifying your monthly budget.

How the Snowball Roll Works

Once your smallest balance reaches zero, the entire amount previously going toward that account (its minimum payment plus your extra payment) rolls into the next smallest balance. This creates a growing 'snowball' of monthly repayment power.

Frequently Asked Questions

Mathematically, the avalanche method (highest APR first) saves more interest. However, many people prefer the snowball method because quick early wins make it easier to stay committed.
