What is the FIRE number?
Your FIRE number is the amount of savings/investments needed to cover your annual expenses indefinitely. It's typically calculated as Annual Expenses × 25 (based on the 4% safe withdrawal rate). With $50,000 in expenses, your FIRE number is $1,250,000.
What is the 4% rule?
The 4% rule suggests you can withdraw 4% of your portfolio annually in retirement with a high probability of not running out of money over 30 years. Based on the Trinity Study, it accounts for inflation adjustments each year.
How do I calculate my savings rate?
Savings rate = (Income - Expenses) / Income × 100. If you make $100,000 and spend $50,000, you save $50,000 — a 50% savings rate. Higher savings rates dramatically reduce years to FIRE.
What's the difference between Lean, Regular, and Fat FIRE?
Lean FIRE (~$30K/year): Minimalist lifestyle, often geo-arbitrage. Regular FIRE ($40-60K): Comfortable middle-class lifestyle. Fat FIRE ($80K+): Premium lifestyle with travel, hobbies, no budget constraints.
Is early retirement really possible?
Absolutely! With a 50% savings rate, you can reach FIRE in about 17 years. With 70% savings rate, it drops to under 10 years. The key is maximizing the gap between income and expenses while investing the difference.
