Snowball vs. Avalanche: Which Debt Payoff Wins?

When you're paying off multiple debts, two methods dominate. The avalanche method targets the debt with the highest interest rate first. The snowball method targets the smallest balance first. Both work; they just optimize for different things.

The avalanche saves the most money

Mathematically, attacking your highest-interest debt first costs you the least in total interest. If your motivation runs on logic and you won't lose steam, this is the efficient choice.

The snowball keeps you motivated

Paying off your smallest balance first gives you a quick, visible win — one fewer bill, one closed account. Research on actual borrowers suggests people who use the snowball are more likely to stick with it, and finishing beats optimizing on paper.

Whichever you pick, the mechanics are the same: pay the minimum on everything, then throw every spare dollar at your target debt. When it's gone, roll that payment into the next one. That rolling momentum is what makes either method powerful.

The best method is the one you'll actually follow to the end. If you're not sure, start with the snowball — an early win is often what turns a plan into a habit.
