Example Calculation

Suppose you are 30 years old, spend $40,000 annually, have $50,000 in savings, and save $15,000 per year with a 7% annual return and a 4% safe withdrawal rate:

  • FIRE Type: Regular FIRE (standard lifestyle)
  • Adjusted annual expenses: $40,000 × 1.25 = $50,000
  • FIRE Number = $50,000 ÷ 0.04 = $1,250,000
  • Current progress: ($50,000 ÷ $1,250,000) × 100 = 4%
  • Years to FIRE: ~30 years
  • FIRE Age: 30 + 30 = 60 years old
  • Monthly Passive Income: ($1,250,000 × 0.04) ÷ 12 ≈ $4,167

The calculator will also display a status message such as “On Track” or “Good Progress” based on your timeline and savings.
