Avalanche — highest rate first
List every debt with balance, minimum payment and interest rate. Pay the minimum on all of them. Any extra money you have goes to the debt with the highest rate. When that debt is gone, roll its payment into the next-highest rate. Mathematically, this pays the least total interest.
Snowball — smallest balance first
Same setup, but the extra money goes to the debt with the smallest balance. You knock out small debts fast and get the psychological win of watching accounts close. You pay more interest overall, but studies (Northwestern Kellogg, 2012) show snowball users are more likely to actually finish payoff.
The hybrid most people should use
Group debts into 'high rate' (18%+ APR — most credit cards) and 'low rate' (student loans, car loans, mortgages). Attack all high-rate debt avalanche-style first because the interest is brutal. For low-rate debt, use whichever feels sustainable.
Key takeaways
- Avalanche = least interest. Snowball = highest completion rate.
- Anything above 18% APR is bleeding you and should be killed first.
- The best strategy is the one you will actually finish.
