What is Fat FIRE? Complete Luxury Retirement Guide

Fat FIRE is achieving financial independence with enough wealth to maintain a luxurious lifestyle without financial constraints. This typically means $100,000-$400,000+ in annual spending, requiring $2.5M-$10M+ in invested assets. Fat FIRE practitioners prioritize comfort, convenience, and premium experiences while still retiring decades before traditional age.

Fat FIRE represents achieving financial independence with enough wealth to maintain a luxurious lifestyle without financial constraints, typically requiring $2.5M-$10M+ in invested assets.

Fat FIRE Thresholds:

  • Entry Level: $2.5M portfolio ($100K/year spending)
  • Comfortable: $5M portfolio ($200K/year spending)
  • Premium: $7.5M portfolio ($300K/year spending)
  • Ultra Fat: $10M+ portfolio ($400K+/year spending)

The Math:

Fat FIRE Number = Annual Spending ÷ 0.035 (3.5% withdrawal rate)
