How Debt Payoff Strategies Work
Both the Avalanche and Snowball methods use the same core principle: pay the minimum on all debts, then put any extra money toward one specific debt. When that debt is paid off, the freed-up minimum payment rolls into the next target debt, creating increasingly larger payments over time.
The Avalanche method targets the debt with the highest interest rate first. This is mathematically optimal because it reduces the amount of interest accruing across your debt portfolio as quickly as possible. However, if your highest-rate debt also has a large balance, it may take a long time to pay off.
The Snowball method targets the debt with the smallest balance first. While you may pay slightly more in total interest, you eliminate individual debts faster, which provides psychological motivation. Research by Harvard Business Review found that people who focused on small wins were more likely to successfully eliminate all their debt.
