The Debt Avalanche Method Explained
The debt avalanche method targets your highest-interest-rate balance first, regardless of size — generally the most cost-efficient payoff order mathematically.
How It Works
- Pay the minimum on every debt
- Put any extra money toward the balance with the highest interest rate
- Once that's paid off, move to the next-highest rate
- Repeat until every debt is paid off
Why It Generally Saves More Money
By tackling the highest-rate debt first, you reduce the amount of interest accruing on your most expensive balance sooner — generally resulting in less total interest paid over the life of your payoff plan compared to the snowball method.
Example Walkthrough (Illustrative Only)
Say you have a $500 balance at 15% APR, a $2,000 balance at 24% APR, and a $6,000 balance at 8% APR. With the avalanche method, you'd direct extra payments to the $2,000 balance first, since it carries the highest rate — even though it isn't the smallest. These numbers are illustrative only, not a guarantee of your own timeline or savings.
