Debt snowball vs debt avalanche
Two ways to pay off several debts: avalanche (highest interest rate first) saves the most interest; snowball (smallest balance first) gives quicker wins.
Sourced from official pages · Updated September 30, 2026💡 Key takeaways
- Avalanche pays extra toward the highest interest rate first and usually saves the most interest.
- Snowball pays extra toward the smallest balance first and can keep you motivated with early wins.
- Either method works if you stay consistent and never skip minimums.
- When a debt is paid off, roll its payment into the next.
The two methods
| Method | How it works | Best for |
|---|---|---|
| Debt avalanche | Pay the minimum on every debt, then put every extra dollar on the debt with the highest interest rate | Saving the most interest |
| Debt snowball | Pay the minimum on every debt, then put every extra dollar on the smallest balance; when one is paid off, roll its payment to the next | Staying motivated with early wins |
In both, when a debt is paid off you add its old payment to the next target, so your total monthly payment stays the same until you are debt-free.
