How we worked it out

Updated as you change the numbers.

  1. FIRE number: $50,000.00 ÷ 4% = $1,250,000.00.
  2. Each year, the balance grows at your real return and you add your saving.

Method and assumptions

FIRE number = yearly spending ÷ withdrawal rate. A 4% rate means 25 times spending. The balance grows once a year, with saving added at the end of each year.
