Minimalist financial independence — retire early with the lowest possible living costs.
Lean FIRE is the most minimalist FIRE strategy, targeting annual expenses under $40,000. It's for those who want financial independence as quickly as possible by minimizing lifestyle costs.
Target Assets = Annual Expenses / Safe Withdrawal Rate. E.g., $30,000 expenses at 4% SWR = $750,000. At a more conservative 3.5%, you'd need ~$857,000.
