Frequently Asked Questions
What is the difference between Lean FIRE and Fat FIRE?
Lean FIRE means retiring on bare minimum expenses (basic needs only). Fat FIRE means retiring with enough to maintain a comfortable or even luxurious lifestyle. Fat FIRE requires 2–3x more corpus than Lean FIRE.
What is Barista FIRE?
Barista FIRE is a middle path — you retire from your high-stress career but do light part-time work to cover some expenses. This halves your required corpus since you only need to fund ~50% of your expenses from investments.
Is the 25x rule valid for India?
The 25x rule (based on 4% withdrawal) was developed for the US. In India, higher inflation (6–7%) suggests a 30–33x multiplier may be safer for a 30+ year retirement.
