What is the FIRE movement?

FIRE stands for Financial Independence, Retire Early. It is a lifestyle movement dedicated to extreme savings and aggressive investing, allowing individuals to retire decades earlier than standard retirement age.

The 4% rule (based on the Trinity Study) states that you can safely withdraw 4% of your investment portfolio in your first year of retirement, adjust for inflation annually, and almost never run out of money.

The Mathematics of Early Retirement (FIRE)

Financial Independence, Retire Early (FIRE) is not magic; it is pure mathematics. By combining an extremely high savings rate (often 50% or more) with disciplined index fund investing, you can build a portfolio large enough to sustain your living expenses indefinitely.

The 25x Rule (The FIRE Number)

FIRE Number = Annual Expenses × 25

If your annual expenses are $40,000, you need a portfolio of $1,000,000 to be financially independent. This is the inverse of the famous 4% safe withdrawal rate rule.

Frequently Asked Questions

What is Lean FIRE vs Fat FIRE?

Lean FIRE involves retiring with a minimalist lifestyle and lower expenses. Fat FIRE involves retiring with a massive portfolio that allows for luxury spending, travel, and a very high standard of living.

Does inflation ruin FIRE calculations?

No. The 4% safe withdrawal rate actually assumes you increase your absolute withdrawal amount every single year to match inflation. The underlying equity investments are assumed to grow faster than inflation over time.
