Snowball vs Avalanche: The Fastest Way to Pay Off Debt

When you owe money on several cards or loans at once, the order you pay them off in changes how fast you become debt-free and how much interest you hand over along the way. Two methods dominate: the debt snowball and the debt avalanche. Both tell you to pay the minimum on every debt, then throw every spare dollar at one target debt until it's gone — they only disagree on which debt to target first.

The debt snowball

The snowball method targets the debt with the smallest balance first, regardless of interest rate. When that debt is cleared, its old minimum payment rolls onto the next-smallest — the payment 'snowballs' and grows as each debt disappears.

The debt avalanche

The avalanche method targets the debt with the highest interest rate (APR) first. Because you're always attacking the most expensive debt, you pay the least total interest and usually become debt-free slightly sooner. The trade-off is motivation: if your highest-rate debt also has a big balance, it can take a while before you clear your first account.

Which should you choose?

• •Choose the avalanche if you're motivated by numbers and want to pay the least interest possible.
• •Choose the snowball if you've struggled to stick with debt payoff before and need quick wins to stay motivated.
• •The gap between the two is often small — the best method is the one you'll actually finish.

The one rule both share

Every extra dollar goes to a single target debt while the rest get only their minimums. Splitting extra money across all debts equally is the slowest, most expensive approach — it keeps every balance alive longer and accruing interest.

1. 1List every debt with its balance, APR and minimum payment.
2. 2Decide how much extra you can add on top of the minimums each month.
3. 3Pick a strategy — smallest balance (snowball) or highest APR (avalanche).
4. 4Pay minimums on everything, and the extra on your target debt.
5. 5When a debt is cleared, roll its payment onto the next target.
