Debt Avalanche vs. Debt Snowball: Mathematical Efficiency vs. Psychology

When systematically clearing liabilities, two primary strategies dominate: the mathematically optimal Debt Avalanche and the psychologically focused Debt Snowball.

Debt Avalanche

The Debt Avalanche method prioritizes debts with the highest interest rates first. Mathematically, this minimizes total interest paid across all accounts and shortens total repayment time.

Debt Snowball

The Debt Snowball method targets the smallest balance first, regardless of interest rate. While slightly less efficient mathematically, clearing small balances quickly provides psychological wins that help keep borrowers motivated.
