About FIRE

FIRE stands for financial independence, retire early. You are financially independent when your investments can cover your spending indefinitely. With a 4% withdrawal rate, that takes 25 times your yearly spending. The biggest lever is your savings rate, because it both grows your portfolio and lowers the amount you need.

The Formulas

FI number = yearly spending ÷ withdrawal rate

Savings rate = (income − spending) ÷ income

Coast FI = FI number ÷ (1 + r)^(65 − age)

r = real (after-inflation) return; savings are added monthly.

Reach FI Sooner

  • •Raising your savings rate helps twice: more invested and less needed
  • •Cut the big three first: housing, transportation and food
  • •Use tax-advantaged accounts to keep more of your returns
  • •A lower withdrawal rate, such as 3.5%, adds a safety margin
  • •Part-time work in early retirement reduces the savings you need
