Complete guide to achieving financial independence and retiring early through strategic saving and investing.

The FIRE movement reimagines retirement as something you can reach decades early through aggressive saving and investing. This guide explains the math, the trade-offs, and how to pursue it realistically.

Key Takeaways

  • The 4% Rule and Safe Withdrawal Rates: The 4% rule suggests you can withdraw 4% of portfolio annually with 95% success over 30 years.
  • Savings Rate Mathematics: Saving 50% of income cuts working years to 17.
  • Lean FIRE vs Fat FIRE: Lean FIRE: $25,000-$40,000 annual spending, minimalist lifestyle.
  • Healthcare Before Medicare: ACA marketplace plans with subsidies.

The 4% Rule and Safe Withdrawal Rates

The 4% rule suggests you can withdraw 4% of portfolio annually with 95% success over 30 years. For early retirement, consider 3-3.5% withdrawal rates. Dynamic withdrawal strategies adjust based on market performance. Sequence of returns risk critical in early years.

Key Points:

4% rule for traditional retirement
3-3.5% for early retirement
Dynamic withdrawal strategies
Sequence of returns matters
Conservative approach for FIRE

Savings Rate Mathematics

Saving 50% of income cuts working years to 17. Saving 65% cuts to 10.5 years. The shockingly simple math: time to FI = LN((1 + SWR/savings_rate) / (1 + investment_return)) / LN(1 + investment_return). Focus on increasing savings rate more than returns.

Key Points:

Higher savings rate = faster FI
50% savings = ~17 years
65% savings = ~10.5 years
Savings rate more important than returns
Use FI calculators for planning

Lean FIRE vs Fat FIRE

Lean FIRE: $25,000-$40,000 annual spending, minimalist lifestyle. Regular FIRE: $40,000-$100,000, comfortable living. Fat FIRE: $100,000+, luxury lifestyle. Barista FIRE: part-time work for benefits. Coast FIRE: savings compound without new contributions.

Key Points:

Lean FIRE: minimalist lifestyle
Regular FIRE: comfortable living
Fat FIRE: luxury lifestyle
Barista FIRE: part-time work
Coast FIRE: no new contributions
