What is Lean FIRE?

Retiring early on low expenses (e.g., $25K–40K/year). Less savings needed than Fat FIRE.

Is the 4% rule safe?

The 4% rule (withdraw 4% annually, adjusted for inflation) has about 95% success over 30 years. More conservative: 3–3.5%.

How do I know my annual expenses?

Track spending for 6–12 months, include taxes, healthcare, insurance. Round up slightly for safety.
