FIRE Calculator FAQs

Everything you need to know about calculating your FIRE number, withdrawal rates, and investment timelines.

FIRE stands for Financial Independence, Retire Early. The goal is to aggressively save and invest a significant portion of your income so your portfolio can generate enough passive returns to cover your living expenses without needing traditional employment.

The 4% Rule stems from the Trinity Study, suggesting you can withdraw 4% of your total invested portfolio in year one of retirement (adjusted for inflation thereafter) with a low probability of running out of money over a 30-year period.

Your FIRE Target is calculated by taking your total annual expenses in retirement and dividing them by your chosen Safe Withdrawal Rate. Using the standard 4% SWR, this is equivalent to multiplying your annual expenses by 25 (the Rule of 25).

It is best to use an inflation-adjusted (real) return rate—typically around 6% to 7% for broad stock market indexes—so that your projected FIRE target and future timeline are shown in today's purchasing power dollars.
