📅 January 6, 2025 📁 Money ⏱️ 13 min read

The FIRE (Financial Independence, Retire Early) movement has transformed thousands of lives, enabling people to escape the traditional work-until-65 paradigm. By combining aggressive saving, strategic investing, and intentional living, FIRE practitioners achieve financial freedom decades before conventional retirement age.

Understanding FIRE: More Than Early Retirement

FIRE isn't just about quitting work—it's about having the freedom to choose. Financial independence means your investments generate enough passive income to cover your living expenses indefinitely, giving you the option to work on your terms or not at all.

The Core FIRE Principle

The foundation of FIRE rests on one simple equation:

  • Save aggressively: 50-70% of income
  • Invest wisely: Low-cost index funds
  • Live intentionally: Optimize spending for happiness
  • Achieve FI number: 25x annual expenses

Types of FIRE

1. Lean FIRE

  • Annual expenses under $40,000
  • Minimalist lifestyle focus
  • Fastest path to retirement
  • Requires $1 million or less

2. Regular FIRE

  • Annual expenses $40,000-$100,000
  • Comfortable middle-class lifestyle
  • Balance between saving and living
  • Target $1-2.5 million

3. Fat FIRE

  • Annual expenses over $100,000
  • Luxurious retirement lifestyle
  • No financial compromises
  • Requires $2.5 million+

4. Barista FIRE

  • Part-time work for benefits/extras
  • Lower FI number needed
  • Maintains social connection
  • Reduces retirement anxiety

5. Coast FIRE

  • Investments grow without contributions
  • Work covers current expenses only
  • Reduced stress immediately
  • Full retirement at traditional age

Calculating Your FIRE Number

The 4% Rule (25x Rule)

Your FIRE number = Annual expenses × 25

Example: $40,000 annual expenses × 25 = $1,000,000 needed

Adjusting for Safety
