Debt Snowball Calculator

Compare snowball and avalanche payoff strategies to find the fastest way out of debt.

About Debt Snowball Calculator

This free debt payoff calculator compares two popular strategies: the snowball method (paying off smallest balances first for psychological momentum) and the avalanche method (paying off highest interest rates first to minimize total interest). It computes the payoff order, months to debt freedom, and total interest paid for each strategy so you can choose the approach that best fits your financial goals.

Two Strategies Compared

See side-by-side results for both snowball (lowest balance) and avalanche (highest interest) payoff methods.
