Debt snowball vs. avalanche: which method should you use?
If you have several debts at once (cards, loans, buy-now-pay-later plans), the key question is: which one gets your extra money first? The two best-known answers are the snowball and the avalanche. Both work; the difference is how much you pay and how you feel along the way.
The rules both methods share
- Always pay the minimum on every debt.
- Put all the extra money you can toward a single debt.
- When you pay it off, roll what you were paying on it into the next one. That way your payment grows like a rolling snowball.
The only thing that changes is the order.
The debt snowball method
You order your debts from smallest to largest balance, regardless of interest rate. You start with the smallest.
- Pro: you pay off your first debt very quickly. Watching a debt disappear is motivating and reduces the number of payments to keep track of.
- Con: you may leave a very expensive debt for last, so you pay more interest overall.
The debt avalanche method
You order your debts from highest to lowest interest rate. You start with the most expensive.
- Pro: mathematically, it's the cheapest option and usually the fastest.
- Con: if your most expensive debt is also large, you might go many months without clearing a single debt, and it's easier to lose heart.
A worked example
Imagine someone with three debts and 250 a month to pay toward them in total:
| Debt | Balance | Annual interest | Minimum payment |
|---|---|---|---|
| Store financing | 600 | 15% | 25 |
| Credit card | 1,500 | 28% | 50 |
| Personal loan | 2,500 | 10% | 80 |
The minimums add up to 155, so there's 95 a month left over for the priority debt.
| Snowball | Avalanche | |
|---|---|---|
| Order | Store → Card → Loan | Card → Store → Loan |
| First debt paid off | Month 6 | Month 12 |
| Debt-free | Month 22 | Month 21 |
| Total interest paid | ≈ 683 | ≈ 619 |
In this case the avalanche saves about 63 and one month. In exchange, with the snowball the first debt disappears in half the time. The bigger the gap in interest rates between your debts, the bigger the avalanche's advantage.
Which one is right for you?
- Choose the avalanche if you're disciplined, motivated by numbers and have one debt with a much higher rate than the rest (usually the credit card).
- Choose the snowball if you've tried to get out of debt before and gave up, if you have lots of small debts or if juggling many payments stresses you out.
- Combine them if you have one or two very small debts: clear them first to build momentum, then order the rest by interest rate.
How to start today
- List all your debts with their balance, interest rate and minimum payment.
- Work out how much you can pay in total each month with a monthly budget.
- Pick a method and order the list.
- Set up automatic minimum payments so you never miss one.
- Every time you clear a debt, cross it off and add its payment to the next one.

Frequently asked questions
Which debt payoff method saves the most money?
The avalanche method, because it tackles the highest-interest debt first. If all your debts have similar rates, the difference between the two methods is small.
Why do so many people recommend the snowball if it costs more?
Because paying off a debt early gives a sense of progress that helps you keep going. A slightly more expensive method you finish beats an optimal one you abandon.
Can I combine both methods?
Yes. A common approach is to clear one or two very small debts first to build momentum, then order the rest by interest rate.
