Frequently asked questions
What is Coast FIRE?
Coast FIRE is the point where your current investments could grow to your retirement target without additional contributions, assuming your return and timeline estimates hold.
How is my FIRE number calculated?
Your FIRE number divides estimated annual retirement expenses by your chosen withdrawal rate.
Why does compounding matter for Coast FIRE?
More years of compounding can reduce the amount needed today because investments have longer to grow before retirement.
How does the withdrawal rate affect Coast FIRE?
A lower withdrawal rate increases both your FIRE number and Coast FIRE number, while a higher rate reduces them but may increase retirement risk.
Are the investment assumptions guaranteed?
No. Actual returns vary, and inflation, taxes, fees, spending changes, and market conditions can materially affect the result.
