How the Avalanche Method works

The debt avalanche method is mathematically optimal. You attack the highest interest rate first, which minimizes the total interest you pay over time.

The math advantage

High-interest debt costs you every single month. By eliminating it first, you stop the bleeding faster and save real money.

The process

  1. List debts from highest APR to lowest
  2. Pay minimums on everything except the highest-rate debt
  3. Put all extra money toward the highest APR
  4. When it's gone, move to the next highest rate
  5. Repeat until debt-free

Is it right for you?

Avalanche is ideal if you're motivated by optimization, you're disciplined enough to stick with a longer first payoff, or you have a debt with a significantly higher rate than the others.
