How It Works

Lean FIRE targets $40-50k/year spending, requiring a portfolio of just $1-1.25M.

The tradeoff: modest housing, used car, minimal travel. But many find contentment in simplicity.

High-cost areas are tough on lean budgets. Consider locations with lower COL: Midwest, Southeast US, or abroad (Portugal, Mexico).

With 50%+ savings rate, lean FIRE is achievable in 15-20 years even on median income.
