FIRE Calculator

Model your Financial Independence, Retire Early path.

Understanding This Calculator

FIRE combines aggressive saving, disciplined investing, and a low-expense lifestyle to reach financial independence potentially decades before the traditional retirement age.

Core Formula

FIRE Number = Annual Expenses × 25 (4% rule)

How much do I need to retire early?

A common FIRE target is 25× your annual expenses. Lean FIRE, Fat FIRE, and Coast FIRE each adjust the target based on lifestyle goals.

What rate of return should I assume?

Most FIRE planners use 6–7% real (after-inflation) long-term equity returns, stress-testing with 4–5% to be conservative.

* All calculations above are theoretical estimates. Actual returns vary based on market performance, fees, taxes, inflation, and economic factors. This tool is for educational purposes only — not financial advice.
