Quick Answer
FIRE uses saving, investing and spending plans to seek greater work flexibility earlier in life. Lean, Traditional, Fat, Coast and Barista FIRE are community labels, not formal standards. The 4% rule is not a guaranteed 4% return; it is a withdrawal guideline based on particular historical data, portfolios, time horizons and inflation adjustments.
Correct Interpretation and Practical Use
Start with the Core Point
Lean FIRE assumes lower spending; Traditional FIRE aims to support a more typical budget; Fat FIRE allows higher spending; Coast FIRE builds an early base and relies on assumed future growth while current income covers current costs; Barista FIRE retains some employment income. Every version depends on longevity, tax, healthcare, currency, sequence risk and actual spending. A single multiple cannot settle the plan.
How to Use This
- Separate essential and flexible spending instead of relying on one total.
- Stress-test different return, inflation and longevity scenarios.
- Include healthcare, insurance, tax and the possibility of returning to work.
