Debt Avalanche vs Snowball: Which Method Should You Use?
The two most popular debt payoff strategies are the avalanche method (highest interest first) and the snowball method (smallest balance first). Here is how they compare.
Quick Comparison
Avalanche Method
Pay minimum on all debts, put extra money toward the debt with the highest interest rate.
- + Saves the most money on interest
- + Mathematically optimal
- + Faster total payoff time
- - First win can take months
- - Requires discipline
Snowball Method
Pay minimum on all debts, put extra money toward the debt with the smallest balance.
- + Quick wins build momentum
- + Psychologically motivating
- + Easier to stick with
- - Costs more in total interest
- - Slower overall payoff
Example: $30,000 in Debt
Suppose you have these debts and can put $800/month toward them:
| Debt | Balance | Rate | Minimum |
|---|---|---|---|
| Credit Card | $8,000 | 22% | $200 |
| Car Loan | $12,000 | 6% | $300 |
| Student Loan | $10,000 | 5% | $150 |
Avalanche Order
- Credit Card (22%)
- Car Loan (6%)
- Student Loan (5%)
Total interest paid: ~$3,200
Debt-free in: ~40 months
Snowball Order
- Credit Card ($8,000)
- Student Loan ($10,000)
- Car Loan ($12,000)
Total interest paid: ~$3,800
Debt-free in: ~42 months
In this case, the avalanche method saves about $600 and gets you debt-free 2 months sooner. Run your own numbers with our debt payoff calculator.
Which Should You Choose?
Choose avalanche if: you are disciplined, your highest-rate debt is not also your largest balance, and saving money matters more to you than quick wins.
Choose snowball if: you have struggled to stick with debt payoff plans before, you have several small debts that can be eliminated quickly, or you need the psychological boost of seeing debts disappear.
The truth: the best method is the one you stick with. A mathematically suboptimal plan you follow beats an optimal plan you abandon. If you are not sure, try snowball for the first 2-3 debts, then switch to avalanche for the rest.
Tips for Either Method
- Always pay minimums on all debts. Missing payments hurts your credit score and triggers late fees.
- Automate your payments. Set up auto-pay for minimums so you never miss one.
- Throw windfalls at debt. Tax refunds, bonuses, and side hustle income should go straight to your target debt.
- Do not add new debt. Cut up the credit cards or freeze them (literally, in ice) while paying off existing balances.
