FIRE Calculator

Free FIRE calculator. Find your financial independence number and how many years until you can retire early.

Your FIRE number is annual expenses divided by your safe withdrawal rate. See it and how long until you reach it.

How the FIRE Calculator works

FIRE (Financial Independence, Retire Early) targets a portfolio equal to annual expenses ÷ safe withdrawal rate. The calculator also projects years until you reach it.

Example calculation

$40,000 expenses at a 4% withdrawal rate needs a $1,000,000 portfolio; with $80,000 invested and $24,000/year added at 7%, that's reached in roughly 18 years.

Tips for using the FIRE Calculator

  • A higher savings rate is the biggest accelerator.
  • Some use 3–3.5% withdrawal to be safer.
  • Budget separately for taxes and healthcare.
