Debt Avalanche vs. Debt Snowball: Which Method Pays Off Debt Faster?

The Debt Avalanche (Mathematically Optimal)

List all debts by interest rate, highest first. Make minimum payments on all debts, then put every extra dollar toward the highest-rate debt. When it's paid off, roll that payment to the next highest rate. This approach minimizes total interest paid.

The Debt Snowball (Psychologically Powerful)

List all debts by balance, smallest first. Make minimum payments on all debts, then attack the smallest balance with extra money. The early wins build momentum and motivation. Dave Ramsey popularized this approach.

Which Is Better?

The avalanche saves more money in interest — often significantly. But research shows many people who start the snowball actually finish their debt payoff, while avalanche followers often quit. The best method is the one you stick with.

A Hybrid Approach

If you have one small debt that's close to payoff, knock it out first for a quick win. Then switch to strict avalanche order for remaining debts. You get the psychological boost without sacrificing too much mathematical efficiency.
