Practical guide
Using the Debt Avalanche Strategy Calculator well
Who this is for
Borrowers focused on minimizing interest dollars paid.
Worked example
Same debts as a snowball plan, but extra payments hit the highest APR first. Total interest usually drops; months to done may be similar or slightly different depending on balances.
When avalanche clearly wins
Large balance gaps plus big APR spreads favor avalanche. If the interest savings are tiny, pick the method you will finish.
Common pitfalls
- Underfunding minimums on other accounts
- Chasing 0% promos without a payoff calendar
