The two most popular debt payoff strategies are the avalanche and the snowball. Both have you pay the minimum on every debt and throw extra money at one target debt — they just disagree on which debt to attack first. Here is how they compare.

With the avalanche, you target the debt with the highest interest rate first, regardless of balance. Because you are killing the most expensive interest first, this method mathematically minimises the total interest paid and clears your debt soonest.
The snowball method (most motivating)
With the snowball, you target the smallest balance first. You get a quick win when the first debt disappears, then roll its payment onto the next. It usually costs slightly more interest than the avalanche, but the early wins keep many people motivated enough to actually finish.
Which should you choose?
- Choose avalanche if you want to pay the least interest and stay disciplined by the numbers.
- Choose snowball if motivation is your biggest risk and quick wins keep you going.
- The best method is the one you will actually stick with to the end.
A worked comparison
For most people with a few cards, the difference in total interest between the two methods is modest — often a few hundred dollars — while the difference in completion rate can be huge. That is why many advisers suggest the snowball for anyone who has struggled to stay on track.
Frequently Asked Questions
Does the avalanche or snowball save more money?
The avalanche method saves more interest because it tackles the highest-rate debt first. The snowball usually costs a little more but can be easier to stick with.
Can I combine the two methods?
Yes. Some people clear one tiny balance first for a quick win (snowball), then switch to attacking the highest rate (avalanche) for the rest.
Do these methods work for any debt?
Yes — credit cards, personal loans, car loans and more. List every debt, pay minimums on all, and direct your extra payment at the chosen target.
