What Is Fat FIRE?
Fat FIRE means achieving financial independence without sacrificing lifestyle. Instead of cutting expenses to retire earlier, Fat FIRE practitioners aim for a larger portfolio that supports generous spending — typically $100,000+/year.
With $120,000 annual expenses at a 4% withdrawal rate, your Fat FIRE number is $3,000,000. This requires either a high income, aggressive savings, or a longer career — but the reward is financial independence with zero lifestyle compromise.
