Coast FIRE — What Is It? FIRE Variant Without Further Saving
Coast FIRE is a financial independence variant where you have enough capital to stop saving — compound interest will do the rest until retirement.
Definition
Coast FIRE is a variant of the FIRE movement where you have accumulated enough investment capital that — thanks to compound interest — will reach full financial independence by traditional retirement age (e.g., 60–65 years) without additional contributions.
In other words: you can stop saving and just "coast" — work only to cover current expenses.
How to Calculate Coast FIRE?
You need two values:
- FIRE Goal — e.g., 1,800,000 PLN (annual expenses × 25)
- Years to Retirement — e.g., 30 years
Assuming a real return rate of 5% annually:
Coast FIRE = FIRE Goal ÷ (1 + return rate)^years
1,800,000 ÷ (1.05)^30 = 416,000 PLN
If you have 416,000 PLN invested at age 30, by age 60 your portfolio will grow to ~1.8 million PLN without any additional contributions.
Who Is Coast FIRE For?
- Young investors — the earlier you start, the less you need (magic of compound interest)
- People tired of the rat race — you want to slow down, work less, or change careers
- Parents — after reaching Coast FIRE threshold, you can reduce working hours
- Freelancers — flexibility in choosing projects without financial pressure
