Debt snowball vs avalanche: which one should you use?
Both methods do the same thing: pay the minimum on every debt and put every extra dollar on one debt at a time. When that debt is gone, its payment rolls into the next one. The only difference is the order.
Updated 3 October 2026
The two orders
- Snowball: smallest balance first. You clear whole debts quickly, which keeps you going.
- Avalanche: highest interest rate (APR) first. You pay less interest overall, and usually finish a little sooner.
In both, every debt keeps getting its minimum payment, so nothing falls behind.
Worked example
Five debts, $37,280 in total, and $1,100 a month to put towards them (the minimums add up to $750, so $350 is extra). Interest is charged monthly at APR ÷ 12.
| Debt | Balance | APR | Minimum |
|---|---|---|---|
| Visa card | $4,850 | 24.99% | $145 |
| Store card | $1,240 | 29.99% | $40 |
| Car loan | $11,600 | 7.40% | $310 |
| Student loan | $18,900 | 5.50% | $205 |
| Medical bill | $690 | 0% | $50 |
| Snowball | Avalanche | |
|---|---|---|
| First debt paid off | Medical bill, month 2 | Store card, month 4 |
| Debt-free in | 39 months | 38 months |
| Total interest | $4,610 | $4,485 |
Here the avalanche saves $125 and one month. The snowball gets its first win two months earlier and clears two debts in the first five months.
Why the gap is often small
The difference depends on how far apart your interest rates are and how big the extra payment is. When the highest-rate debt is also one of the smallest (common with store cards), both orders start in almost the same place. When a large credit card balance sits at 25% next to small low-rate loans, the avalanche can save hundreds or thousands.
How to choose
- Pick the avalanche if the savings are large on your numbers and you're happy to wait for the first payoff.
- Pick the snowball if you've started and stopped before. A plan you finish beats a cheaper plan you abandon.
- Mix them if one debt matters for another reason, such as a loan from family or a card with a promo rate about to end. Put that one first, then follow either rule.
Things that change the result
- 0% promo rates: note when they end. After that the debt jumps up the avalanche order.
- New charges: any new spending on the cards pushes the date back. The plan assumes none.
- Extra cash: a tax refund or bonus put on the focus debt shortens the plan in both methods.
- Real statements: lenders may charge interest daily, so balances drift a little from any plan. Update the balances every few months.
