Fat FIRE is the opposite of Lean FIRE: achieving financial independence while maintaining a comfortable or luxurious lifestyle. In India, this might mean annual expenses of ₹20–50 lakh or more, requiring a corpus of ₹5–12 crore or higher.

Fat FIRE adherents prioritize lifestyle quality—travel, hobbies, premium healthcare, better housing—over early retirement date. They typically work longer or earn more to build a larger corpus.

Fat FIRE offers more buffer for inflation, healthcare, and unexpected expenses. The trade-off is a longer accumulation phase and higher savings rate required.
