FIRE 25x Calculator
Determine whether a corpus equal to 25× your annual expenses will sustain your retirement over 50 years, given your expected return and inflation rate.
FIRE (Financial Independence, Retire Early): The 25× rule is a popular guideline suggesting you need a corpus of 25 times your annual expenses to retire early. At a ~4% withdrawal rate, this amount typically lasts 30+ years if market returns and inflation remain steady.
This calculator simulates how your FIRE corpus evolves each year as it grows with your expected investment return but shrinks from annual expense withdrawals (which rise with inflation). If the final corpus hits 0, your funds are depleted under current assumptions.
