Debt snowball vs. avalanche: which pays off your debt faster?
Both methods pay the minimum on every debt and throw everything left over at one of them. The difference is which one gets the extra first.
The two methods in one sentence each
- Snowball: the extra goes to the smallest balance. You clear the first debt fast, and its payment then rolls into the next one.
- Avalanche: the extra goes to the highest interest rate. By design, it pays the least interest overall.
A worked example
Three debts and $600 a month to pay them ($375 covers the minimums; $225 is extra):
| Debt | Balance | APR | Minimum |
|---|---|---|---|
| Credit card A | $4,500 | 29.99% | $90 |
| Credit card B | $1,200 | 22.99% | $35 |
| Car loan | $8,000 | 7% | $250 |
| First debt paid off | All paid off | Interest paid | |
|---|---|---|---|
| Snowball (card B → card A → car) | Month 5 | 27 months | $2,469 |
| Avalanche (card A → card B → car) | Month 18 | 27 months | $2,332 |
The avalanche saves $137 here. The snowball clears its first debt 13 months earlier — and that early win is exactly why many people who stall on the avalanche stick with the snowball.
Which one should you pick?
- If your rates are far apart (credit cards versus a car loan), the avalanche saves real money.
- If you have tried before and lost steam, the snowball tends to work better: watching a debt disappear early keeps the plan alive.
- Either way, check whether you can move expensive debt to a cheaper rate first (a 0% balance transfer or a lower-rate personal loan) — and mind the transfer fee.
