If you're carrying more than one debt, the order in which you pay them off matters — both for how much interest you pay and for how likely you are to stick with the plan. Two strategies dominate the conversation: the debt snowball and the debt avalanche.
How the debt snowball method works
List your debts from smallest balance to largest, regardless of interest rate. Pay the minimum on everything except the smallest debt, and throw every extra dollar at that one until it's gone. Then roll that entire payment into the next-smallest debt, and repeat.
Why it works psychologically
How the debt avalanche method works
List your debts from highest interest rate to lowest, regardless of balance. Pay the minimum on everything except the highest-rate debt, and direct every extra dollar there first. Once it's paid off, move to the next-highest rate.
Why it wins on paper
Side-by-side comparison
| Debt Snowball | Debt Avalanche | |
|---|---|---|
| Order of payoff | Smallest balance first | Highest interest rate first |
| Total interest paid | Usually higher | Usually lowest possible |
| Time to first win | Faster | Slower, depending on balances |
| Best for | Staying motivated / momentum | Minimizing total cost |
How to decide which one to use
- List every debt with its balance, interest rate, and minimum payment.
- If you've struggled to stick with financial plans before, start with the snowball for the early motivation boost.
- If you're confident in your consistency and want to minimize cost, use the avalanche.
- Use a debt payoff calculator to see your actual payoff date and total interest under each approach before committing.
- Whichever method you choose, automate the minimum payments so you never miss one — a single missed payment can undo the benefit of either strategy.
Both methods work because they share the same core mechanism: concentrating extra payments on one debt at a time instead of spreading them thin. The 'right' method is simply the one you'll actually follow through to zero.
