1. What Is the FIRE Movement and How Does It Work?
The FIRE (Financial Independence, Retire Early) movement is a financial strategy where people:
✔️ Save and invest aggressively (50-70% of income).
✔️ Reduce expenses and live below their means.
✔️ Build enough passive income to cover all living expenses without working.
Different Types of FIRE:
🔥 Lean FIRE – Retiring early with minimal expenses (small home, low-cost living).
🔥 Fat FIRE – Retiring early with a luxury lifestyle and high net worth.
🔥 Coast FIRE – Saving enough so your investments grow without needing extra contributions.
🔥 Barista FIRE – Achieving financial independence but working part-time for additional income.
📌 Example: Many FIRE followers retire in their 30s or 40s by aggressively saving, investing, and living below their means.

2. How to Calculate Your FIRE Number (The Money You Need to Retire Early)
Your FIRE number is the total amount of money you need to retire comfortably and live off investments.
The 4% Rule (Safe Withdrawal Rate)
✔️ You need 25x your annual expenses to retire early.
✔️ You can withdraw 4% of your total portfolio every year without running out of money.
📌 Example FIRE Calculations:
- If you need $40,000/year to live, you need $1 million invested.
- If you need $100,000/year, you need $2.5 million invested.

✔️ Index Funds & ETFs – Low-cost investments that grow 8-10% annually.
✔️ Real Estate – Rental properties generate passive income in retirement.
✔️ Dividend Stocks – Stocks that pay regular passive income.
