What Is Coast FIRE?
Coast FIRE is a financial independence strategy where you save enough money early in life so that your investments grow on their own to cover your retirement — without needing to save another dollar. Once you reach your Coast FIRE number, you can "coast" through the rest of your career without additional retirement savings.

The Coast FIRE Formula
The Coast FIRE formula calculates how much you need today so your investments grow to your FIRE number by retirement:
FIRE Number = Annual Expenses / Safe Withdrawal Rate
For example, if your annual expenses are $40,000, you're 30 years from retirement, expect 7% returns, and use a 4% withdrawal rate:
- FIRE Number: $40,000 / 4% = $1,000,000
- Coast FIRE Number: $1,000,000 / (1.07)30 = $131,367
If you already have $131,367 invested today, you've reached Coast FIRE — you never need to save another dollar for retirement.
