Financial Independence, Retire Early, calculated precisely. Find your number, track your progress, and see exactly how many years until work becomes optional.
FIRE (Financial Independence, Retire Early) is a movement built around aggressive saving and investing to achieve financial freedom decades before the traditional retirement age of 65. The core idea: save 50-70% of your income, invest in low-cost index funds, and retire when your portfolio reaches 25 to 33 times your annual expenses.
Your FIRE number is calculated by dividing your annual expenses by your Safe Withdrawal Rate (SWR). The famous 4% rule, based on the Trinity Study, suggests you can safely withdraw 4% of your portfolio annually in retirement with a very low risk of running out of money over 30 years. For a longer retirement (40+ years), many in the FIRE community recommend a more conservative 3-3.5% withdrawal rate.
There are several FIRE variations: Lean FIRE (living on $25-40K/year, minimal lifestyle), Regular FIRE (maintaining a middle-class lifestyle on $40-100K/year), and Fat FIRE (enjoying a luxurious retirement on $100K+/year). Each requires a different savings target and timeline.
The biggest lever for accelerating your FIRE date is your savings rate. Increasing your savings rate from 30% to 50% can cut your time to FIRE by nearly half. This calculator lets you model different scenarios by adjusting your monthly contributions, expected returns, and withdrawal rate.
