FIRE Calculator

Enter your target annual spending and a safe withdrawal rate (like the 4% rule) to find the nest egg you need for FIRE. Add your current savings, monthly contribution, and expected return to estimate how many years it takes to get there.

Input

Estimate the nest egg you need for FIRE (financial independence, retire early) from your target annual spending and withdrawal rate. Add your current savings, monthly contribution, and expected return to estimate how many years it takes. This is a simplified guide that assumes a constant rate of return.

How it works

  • Your FIRE number is calculated as "target annual spending ÷ withdrawal rate." At a 4% withdrawal rate (the 4% rule), that works out to 25 times your annual spending.
  • The 4% rule is a rule of thumb from U.S. research (the Trinity Study) suggesting that withdrawing 4% or less of your portfolio each year makes it unlikely to run out over a long retirement. You can pick 4%, 3.5%, 3%, or enter any custom rate.
  • Years to FIRE are estimated by growing your current savings at the expected annual return (split into a monthly rate), adding your contribution at the end of each month, and finding the first month your balance reaches the FIRE number.
  • Progress is "current savings ÷ FIRE number," the shortfall is "FIRE number − current savings," and the monthly withdrawal is "annual spending ÷ 12" — a guide to what you could spend each month after reaching FIRE.
  • This is a simplified estimate that assumes a constant rate of return. Real returns vary and you can lose money; taxes, fees, inflation, pensions, and social security are not included. Make investment and retirement decisions at your own risk and consult a professional when needed.
