Lean FIRE

Lean FIRE Number = Lean Budget / Withdrawal Rate

Lean FIRE is achieving financial independence on a below-average budget (typically under $40,000/year for an individual).

Lean FIRE Examples

BudgetFIRE Number (4%) $20,000$500,000 $25,000$625,000 $30,000$750,000 $35,000$875,000

计算示例

$30,000 lean budget, 4% withdrawal, $150,000 saved.

  1. Lean FIRE number = $30,000 / 0.04 = $750,000
  2. Progress = $150,000 / $750,000 = 20%
  3. Remaining = $600,000
