What Is Coast Fire?

Coast Fire is a financial milestone that allows you to stop contributing to your retirement fund and still reach financial independence by your target retirement age. It works by saving a large enough amount early, then letting compound interest grow your savings until retirement. Once you hit this number, your money “coasts” to financial freedom without further contributions.
How Does the Coast Fire Calculator Work?
To start, you’ll need to enter the length, width, and thickness of the area you’re paving. These three measurements are all you need to determine the required amount of asphalt.
The calculator takes four main inputs:
Current Age
Retirement Age
Current Savings
Expected Rate of Return
Using these inputs, it calculates the amount your savings will grow by retirement. If that projected amount meets your financial independence target, you’re on track for Coast Fire.
Example of Calculation
Imagine you’re 30, want to retire at 60, and have $50,000 saved with a 7% return. The calculator estimates if your current savings will grow to your needed retirement fund without any further contributions.
