Preguntas Frecuentes
Is Lean FIRE sustainable long-term?
It can be, but it leaves little margin for unexpected expenses. Consider building a buffer (aiming for 10-20% above your Lean FIRE number) and having a flexible spending plan that adjusts withdrawals in down markets.
What about healthcare on a lean budget?
At low income levels, you may qualify for significant ACA subsidies, making health insurance affordable. Lean FIRE income often falls within the subsidy-eligible range. Research your state marketplace options.
How is Lean FIRE different from regular FIRE?
Regular FIRE targets average spending (roughly $40,000-$100,000/year). Lean FIRE targets below-average spending. Fat FIRE targets above-average spending. All use the same withdrawal rate math with different expense levels.
