What is FIRE?
FIRE stands for Financial Independence, Retire Early. It's a lifestyle movement focused on extreme savings and investment to achieve financial independence much earlier than traditional retirement age. The goal is to accumulate enough assets so that investment income covers all living expenses.
The 4% Rule (Safe Withdrawal Rate)
Where:
Annual Expenses = Your yearly living costs
25 = 1 ÷ 4% (the inverse of the safe withdrawal rate)
FIRE Number = Amount needed to achieve financial independence
Based on the Trinity Study, withdrawing 4% annually from your portfolio provides high probability (95%+) of your money lasting 30+ years.

FIRE Strategies
Coast FIRE
Save enough early so compounding alone will grow your portfolio to your FIRE number without additional contributions. You can then reduce work intensity.
Geoarbitrage FIRE
Achieve FIRE by moving to lower cost-of-living areas, either domestically or internationally, to stretch your retirement savings further.
Sequence of Returns Risk Management
Maintain cash buffer (2-3 years expenses) during early retirement to avoid selling investments during market downturns.
Important Considerations
- Market returns are not guaranteed - plan for sequence risk
- Healthcare costs can be significant before Medicare eligibility
- Inflation can erode purchasing power over long retirement
- Consider tax implications of withdrawal strategies
- Maintain flexibility - be prepared to adjust spending or earn income
- Build emergency fund for unexpected expenses
Frequently Asked Questions
Is the 4% rule still valid?
The original Trinity Study showed 4% withdrawal rate had 95% success over 30 years. More recent studies suggest 3-3.5% might be safer for longer retirements (50+ years). Consider your personal risk tolerance and flexibility.
What savings rate do I need for FIRE?
With 50% savings rate, you can reach FI in about 17 years. At 70% savings rate, it drops to about 8.5 years. The relationship is exponential - small increases in savings rate significantly reduce time to FI.
How do I calculate my FIRE number?
FIRE Number = Annual Expenses × 25 (for 4% withdrawal rate). For more conservative 3.5% withdrawal: Annual Expenses × 28.6. For aggressive 5% withdrawal: Annual Expenses × 20.
What investment returns should I assume?
Conservative estimates use 5-7% after inflation. Historical stock market returns average 7-10% before inflation. Use 5-6% real returns for balanced portfolio. Always run different scenarios to see impact.
