Frequently Asked Questions

What is the FIRE movement and what does it mean?

FIRE stands for Financial Independence, Retire Early. It is a financial framework where individuals maximize their savings rate (often 40%–70% of income) and invest in low-cost index funds until their portfolio generates enough passive income to cover their living expenses forever.

What is the 4% Safe Withdrawal Rule?

Originating from the landmark Trinity Study, the 4% rule states that you can withdraw 4% of your starting investment portfolio each year (adjusted annually for inflation) with a 95%+ probability that your portfolio will never run out of money over a 30-year retirement.

How is your FIRE Number calculated?

Your FIRE number is your annual living expenses multiplied by 25 (under a 4% rule) or multiplied by 33 (under a conservative 3% rule). For example, if you live comfortably on $60,000 per year, your FIRE number is $1,500,000.

What is the difference between Lean FIRE, Standard FIRE, and Fat FIRE?

Lean FIRE focuses on covering strictly essential, minimalist expenses (typically under $40,000/year). Standard FIRE maintains a comfortable middle-class lifestyle ($50,000–$100,000/year). Fat FIRE accounts for abundant luxury spending ($120,000+/year) without financial restraint.
