What is FIRE?
Financial Independence, Retire Early is a movement focused on saving aggressively (50-70% of income) to retire decades early.
The 4% rule: If you have 25x your annual expenses invested, you can withdraw 4% per year and (historically) never run out.
Example: Spend $40k/year → FIRE number = $1 million → Withdraw $40k/year forever
Types of FIRE:
- Lean FIRE: Retire on $30-40k/year (minimalist lifestyle)
- Regular FIRE: Retire on $50-80k/year (comfortable)
- Fat FIRE: Retire on $100k+/year (luxurious)
