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

  1. Pay the minimum on every debt
  2. Put any extra money toward the balance with the highest interest rate
  3. Once that's paid off, move to the next-highest rate
  4. 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.
