How this calculator works

FIRE number = yearly expenses ÷ withdrawal rate. The timeline grows your current investments plus yearly savings at the expected return until they reach that number.

Frequently asked questions

Should I use today’s money or future money?

Use today’s expenses and a real (after-inflation) return, such as 4–5%, to keep everything in today’s terms.

Is 4% safe for very early retirement?

Many early retirees use 3–3.5% for extra safety because their money must last longer than 30 years.
