Debt snowball vs. avalanche: which should you use?
Both methods pay minimums on everything and send extra money to one debt at a time. The difference is which debt goes first, and that choice changes your cost and your motivation.
How each method works
Smallest balance first
List debts from smallest to largest balance. Pay minimums on all, then put every extra dollar on the smallest. When it's gone, roll its payment into the next.
Highest rate first
List debts from highest to lowest APR. Pay minimums on all, then put every extra dollar on the highest-rate debt. When it's gone, move to the next highest.
A worked example
Three debts, the same minimum payments and $200 extra each month:
| Debt | Balance | APR | Minimum |
|---|---|---|---|
| Store card | $600 | 27.99% | $25 |
| Credit card | $3,500 | 23.99% | $105 |
| Car repair loan | $1,800 | 12% | $80 |
| Method | Payoff order (month paid off) | Debt-free | Total interest |
|---|---|---|---|
| Snowball | Store card (3), Car repair loan (9), Credit card (17) | 17 months | $998 |
| Avalanche | Store card (3), Credit card (15), Car repair loan (17) | 17 months | $876 |
Avalanche saves $122 here because the big credit card at 23.99% gets paid down sooner. Snowball clears the car loan by month 9, which some people find more motivating.

Ways to speed up either method
- Stop adding new chargesUse cash or debit while you pay down cards.
- Ask for a lower rateA call to your card issuer sometimes works, especially with on-time history.
- Use windfallsTax refunds, bonuses and side income go straight to the target debt.
- Consider a lower-rate consolidationOnly if the new APR is lower and you won't run balances back up.
Frequently asked questions
Is avalanche always cheaper?
Mathematically it costs the same or less than snowball when everything else is equal. The difference can be small when rates are similar.
Should I include my mortgage or student loans?
Most people focus these methods on higher-rate consumer debt like cards and personal loans, and keep making regular payments on mortgages and low-rate student loans.
What if I can't afford the minimums?
Call your creditors about hardship programs and talk with a nonprofit credit counselor before choosing a payoff method.
