What Coast FIRE means
Coast FIRE estimates the amount you would need invested today so that, with no additional contributions, it could grow to your full FIRE target by the retirement date you choose.
The calculation assumes a constant annual return and withdrawal rate. Real returns vary, and the estimate does not model taxes, fees, inflation changes, or sequence-of-returns risk.
