Common questions
About this calculator
What does FIRE mean?
FIRE means Financial Independence, Retire Early. The core idea is building enough invested assets to cover expenses without active income.
Is the 4% rule guaranteed?
No. It is a planning rule of thumb. Taxes, fees, inflation, market returns, and retirement length all matter.
How it works
The FIRE target equals annual expenses divided by the withdrawal rate.
The timeline compounds current investments monthly and adds monthly contributions.
The withdrawal rate is an assumption, not a guarantee of future portfolio safety.
Educational planning estimate. It does not replace an official calculation or individualized financial, tax, or legal advice.
