FIRE Calculator

Computes the portfolio that supports your annual spending at a chosen safe withdrawal rate — the FIRE number — and simulates how many years of saving at your current pace it takes to get there.

Notes

  • The 4% rule comes from the Trinity study of US 30-year retirements; longer horizons and non-US portfolios argue for a more conservative rate.
  • This is an educational estimate, not financial advice; talk to a qualified adviser before making money decisions.
