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

The avalanche method saves the most money; the snowball method keeps you motivated. Here's how to choose between them.

The two methods

Both strategies assume you pay the minimum on every debt and throw all your extra money at one target debt until it's gone, then roll that freed-up payment to the next. They differ only in which debt you target first.

The avalanche method targets the debt with the highest interest rate first. Because you're killing the most expensive debt first, it minimizes total interest and pays everything off fastest in dollar terms. The snowball method targets the smallest balance first, regardless of rate, to score a quick win and build momentum.

Which is better?

Mathematically, the avalanche always wins — it costs the least interest and clears your debt soonest. If you have, say, a 24% credit card and a 6% car loan, attacking the card first is clearly cheaper.

But personal finance is behavioral. The snowball's early payoff of a small debt delivers a psychological win that helps many people stick with the plan, and research has found that starting with the smallest balance can improve the odds of actually becoming debt-free. The best method is the one you'll follow through on.

Run your own numbers

The gap between the two methods is often small if your balances and rates are similar — in which case pick the snowball for motivation. If you carry one large high-rate balance, the avalanche's savings are worth the discipline. Use the credit-card payoff calculator to see how fast extra payments clear a balance either way.
