Debt Avalanche vs Snowball
Two popular ways to pay off several debts. One saves the most money, the other keeps you motivated. Here is how each works and how to pick.
Bottom line: the avalanche method saves the most interest because it targets your highest-rate debt first. The snowball method targets your smallest balance first for quick, motivating wins. The best one is the method you will actually stick with until the debt is gone.
How the avalanche method works
Keep paying the minimum on every debt, then throw every extra dollar at the debt with the highest interest rate. When it is gone, roll that payment into the next-highest rate, and so on. Because you are killing your most expensive debt first, this saves the most in total interest and often finishes a little sooner.
How the snowball method works
Same idea, different target: pay minimums on everything, then put every extra dollar toward your smallest balance, regardless of rate. Clear it, then roll that payment into the next-smallest. You get a debt fully paid off quickly, which builds momentum and makes the plan easier to stick with.
Which one saves more?
On pure math, avalanche wins, because paying the highest rate first always reduces total interest. The gap can be small or large depending on how different your rates are. Snowball can cost a bit more in interest but has a real advantage: people are more likely to finish, because the early wins keep them going. A plan you complete beats a cheaper plan you abandon.
The hybrid approach
Many people split the difference: knock out one or two very small balances first for the motivation, then switch to avalanche and attack the highest rates. That captures the quick win without giving up much interest savings.
How to run either one
List your debts with balances and rates, keep minimums on all of them, and direct every extra dollar to your chosen target. Both methods are Step 4 of the broader plan to pay off credit card debt. To see how much faster extra payments clear a card, and how much interest you save, use the calculators:
Frequently asked questions
Is avalanche or snowball better?
Avalanche saves more interest by targeting the highest rate first. Snowball builds motivation by clearing the smallest balance first. The best is whichever you will stick with.
Does the snowball method cost more?
Usually a little, because it ignores interest rates. The trade-off is that the early wins help many people actually finish, which matters more than a small interest difference.
Can I combine the two?
Yes. A common hybrid clears one or two tiny balances first for momentum, then switches to avalanche to minimize interest on the rest.
Do I stop paying the other debts?
No. Keep making the minimum payment on every debt so all accounts stay current. You only add your extra money to the one target debt.
