Debt Avalanche vs Snowball: Two Ways to Get Out of Debt
Both methods work by throwing extra money at one debt at a time. The avalanche saves the most interest; the snowball keeps you motivated. Here's how to choose.

When you owe on several cards or loans, the fastest way out is to make minimum payments on everything and throw every spare dollar at one target debt until it's gone, then roll that payment onto the next. The only question is which debt to target first — and that is where the avalanche and snowball methods differ.
The avalanche: attack the highest rate
The avalanche method targets the debt with the highest interest rate first, regardless of balance. Mathematically this is optimal: you kill your most expensive debt fastest, so you pay the least total interest and get out of debt soonest. If you are motivated by numbers, this is the method for you.
The snowball: attack the smallest balance
The snowball method targets the smallest balance first, regardless of rate. You clear individual debts quickly, and each payoff delivers a burst of momentum that keeps you going. It usually costs a little more in interest than the avalanche, but for many people the psychological wins are what make the difference between finishing and giving up.
- Avalanche — order debts by interest rate, highest first. Lowest total cost.
- Snowball — order debts by balance, smallest first. Fastest visible wins.
- Both — pay minimums on all, put every extra dollar on the target, then roll it forward.
Which should you pick?
If your interest rates are all similar, the two methods finish at nearly the same time, so pick the snowball for motivation. If one debt has a punishing rate — a card at 25% while everything else is under 10% — the avalanche can save real money. The best method is ultimately the one you will actually stick with.
