Use this coast FIRE calculator to estimate the savings you need to cover your expenses until traditional retirement age, without needing further income.

## How to Use the Coast FIRE Calculator

Enter your current savings, expected annual return rate, and the number of years until retirement. Then click on “Calculate” to see your Coast FIRE number, which is the amount you will have at retirement without making any additional contributions.

## How Coast FIRE Calculation Works

This calculator uses the formula for compound interest to project the growth of your current savings. The formula applied is FV = PV * (1 + r)^n, where FV is the future value of the investment, PV is the present value or current savings, r is the annual return rate, and n is the number of years until retirement.

## Limitations of the Calculator

This calculator assumes a constant return rate and doesn’t factor in inflation, taxes, or any changes to your financial situation. Investment returns can fluctuate, and past performance is not indicative of future results. This tool should be used as a starting point for planning and not as a definitive guide.
