Methodology

How this calculator works

Built by · Updated

Formula

  • FIRE number = annual expenses ÷ safe withdrawal rate (4% by default, i.e. 25× expenses)
  • Years to FIRE = ln((C + T × i) ÷ (C + S × i)) ÷ ln(1 + i) ÷ 12, with C = monthly savings, T = FIRE number, S = current savings, i = annual return ÷ 12

Assumptions & limits

  • Expenses stay constant. To keep everything in today’s money, enter a real (after-inflation) return.
  • Constant return, no taxes.

Sources

  • William P. Bengen (1994), "Determining Withdrawal Rates Using Historical Data", Journal of Financial Planning (origin of the 4% rule)
  • Cooley, Hubbard & Walz (1998), "Retirement Savings: Choosing a Withdrawal Rate That Is Sustainable" (the Trinity study)
