How avalanche vs snowball work

Avalanche pays minimums on every card, then throws all extra at the card with the HIGHEST APR. Mathematically optimal, minimizes total interest paid.

Snowball pays minimums on every card, then throws all extra at the card with the SMALLEST BALANCE. Suboptimal mathematically but psychologically powerful, quick wins keep momentum.

For most people with $5K-30K in card debt and 3+ cards, the difference is 6-24 months of payoff time and $500-3000 in interest. This calc shows both side-by-side.
