Frequently Asked Questions

Common questions about FIRE and early retirement planning

What is the FIRE method for retirement?

FIRE (Financial Independence, Retire Early) is a movement focused on saving and investing aggressively to retire much earlier than traditional retirement age. It typically involves saving 25 times your annual expenses and following the 4% withdrawal rule.

How much do I need to retire early?

Using the FIRE method, you need to save 25 times your annual expenses. For example, if you spend $40,000 per year, you'd need $1 million saved. This allows you to withdraw 4% annually while preserving your principal.

Is the 4% withdrawal rule safe?

The 4% rule is based on historical market data and is considered relatively safe for 30+ year retirements. However, market conditions vary, and many financial experts recommend being flexible with withdrawal rates based on market performance.
