How to Retire Early: The FIRE Movement Explained

What Is FIRE?

FIRE stands for Financial Independence, Retire Early. It's a lifestyle movement focused on saving aggressively (typically 50-70% of income) so you can retire decades earlier than the traditional age of 65.

The 4% Rule

The 4% rule is the cornerstone of FIRE planning. It states that if you withdraw 4% of your portfolio annually, adjusted for inflation, your money should last 30+ years. To calculate your FIRE number: multiply your annual expenses by 25.

Example: If you need $40,000/year to live, your FIRE target is $40,000 × 25 = $1,000,000.

FIRE Strategies

• Lean FIRE — Retire early with minimal expenses (under $40k/year)
• Fat FIRE — Retire with a higher standard of living (over $80k/year)
• Barista FIRE — Retire from career but work part-time for benefits and extra income
• Coast FIRE — Save enough early so it grows to your FIRE number by traditional retirement age

Key Principles

1. Track your spending — Know exactly where every dollar goes
2. Increase your savings rate — Cut expenses and increase income
3. Invest in low-cost index funds — Focus on broad market ETFs with low fees
4. Optimize taxes — Use retirement accounts strategically
5. Avoid lifestyle inflation — Don't increase spending as income grows

Is FIRE Right for You?

FIRE requires discipline and sacrifice. It's not about depriving yourself — it's about intentional spending. If you value financial freedom and are willing to make trade-offs, FIRE could be life-changing.
