Debt snowball vs. avalanche: which one is better?
Last updated November 9, 2026
The snowball and avalanche methods are the two most common ways to pay off several debts. They share the same first step: pay the required minimum on every debt, then send all your extra money to one chosen debt. The only difference is which debt gets chosen.
How each method works
- Avalanche: extra money goes to the debt with the highest interest rate first. When it is paid off, you move to the next highest rate.
- Snowball: extra money goes to the debt with the smallest balance first. When it is paid off, you move to the next smallest.
In both methods, when a debt is paid off its old payment is added to the next target. The payments snowball (or avalanche) as you go.
A worked example
Say you owe three debts and can add $200 a month beyond the required payments:
| Debt | Balance | APR | Payment |
|---|---|---|---|
| Store credit card | $4,100 | 29.99% | $125 |
| Personal loan | $2,400 | 14.5% | $120 |
| Car loan | $14,500 | 7.4% | $410 |
Here is how the methods compare when run month by month:
| Method | Order | Time to debt-free | Total interest |
|---|---|---|---|
| Minimums only | None | 70 months | $6,847 |
| Avalanche | Card, personal, car | 28 months | $2,792 |
| Snowball | Personal, card, car | 29 months | $3,072 |
Avalanche saves $280 and finishes a month sooner. Both methods beat minimum payments by a wide margin. The gap between the two is small here because the debts with the highest rates are also fairly small. The gap grows when your largest balance also carries the highest rate.
When the snowball makes sense
Snowball clears a debt sooner, so the number of bills drops faster. If seeing progress keeps you going, that can matter more than a few hundred dollars of interest. A plan you stick with beats a perfect plan you abandon.
When the avalanche makes sense
If you are comfortable waiting longer for the first payoff, avalanche usually costs the least. It matters most when the rates are far apart, such as a 29% card next to a 5% loan.
A third option: cash flow
Some people target the debt whose monthly payment is large compared with its balance. Paying it off frees the most monthly cash, which can help when the budget is tight. Our planner includes this method too.
Try your own numbers
The result depends on your balances, rates and payments, so run your own. The planner shows all three methods side by side.
