Frequently Asked Questions

What is the FIRE movement?

FIRE stands for Financial Independence, Retire Early. The goal is to save and invest aggressively so your portfolio generates enough passive income to cover your expenses indefinitely.

What is the FIRE number?

Your FIRE number is the total portfolio size you need to retire. The most common formula is 25× your annual expenses (based on the 4% safe withdrawal rate rule).

What is the 4% rule?

The 4% rule states that you can withdraw 4% of your portfolio annually and it will last 30+ years in most historical market scenarios. It comes from the Trinity Study.

What savings rate do I need to retire early?

A 50% savings rate typically means financial independence in about 17 years from zero. A 70% savings rate can achieve it in under 9 years. The savings rate is the most powerful lever.
