Formula Sources: Investopedia – FIRE Guide | Forbes – The 4% Rule
Variables:

- Safe Withdrawal Rate (SWR): The percentage of your portfolio you can withdraw annually without running out of money (Commonly 4%).

What is Financial Independence Retire Early Calculator?
A financial independence retire early calculator is a strategic tool designed to help individuals determine how much capital they need to accumulate to live off their investments indefinitely. This movement, known as FIRE, focuses on extreme saving and investing to retire decades earlier than the standard age of 65.
By using this calculator, you can visualize how changes in your spending or savings rate impact your timeline. It transforms abstract goals into a concrete “FIRE Number,” providing a clear target for your financial journey.
How to Calculate Financial Independence Retire Early Calculator (Example):
- Determine your annual expenses. Let’s say $50,000.
- Choose your SWR. If using the 4% rule, divide $50,000 by 0.04. Result: $1,250,000 (Your FIRE Number).
- Compare this with your current savings (e.g., $100,000).
- Factor in your annual contributions (e.g., $25,000) and expected returns (7%).
- Apply the time-value-of-money formula to find the years remaining to reach the goal.

Frequently Asked Questions (FAQ):
What is the 4% Rule in FIRE? The 4% rule is a guideline suggesting that if you withdraw 4% of your initial portfolio value (adjusted for inflation) annually, your money should last at least 30 years.
Should I include social security in my FIRE calculation? Most FIRE enthusiasts exclude it to be conservative, or treat it as a “bonus” income later in life.
How does inflation affect the FIRE number? The calculator usually assumes “Real Return” (nominal return minus inflation), so your FIRE number stays relevant in today’s dollars.
What is the difference between Fat FIRE and Lean FIRE? Lean FIRE is retiring on a minimal budget (often < $40k/yr), while Fat FIRE allows for a more luxurious lifestyle (> $100k/yr).
