Introduction
The Coast FIRE Calculator helps you find out when you can stop saving for retirement and still reach your goals. Coast FIRE means you have saved enough money that will grow on its own to support your retirement, even if you never add another dollar.
This tool shows you exactly when you can reach Coast FIRE based on your current savings, how much you save each month, and what you want to spend in retirement. Once you hit your Coast FIRE number, your money will keep growing by itself until you're ready to retire. This means you can work less, change to a lower-paying job you love, or just stop worrying about saving every extra penny.
Simply enter your age, current savings, and retirement goals to see your personal Coast FIRE timeline. The calculator will show you how many years until you reach Coast FIRE, what age you'll be, and how your money will grow over time.

What is Coast FIRE?
Coast FIRE is a money goal that lets you stop saving for retirement early. When you reach Coast FIRE, you have saved enough money that will grow on its own to support your retirement. This means you can stop adding money to your retirement accounts and just let your current savings grow over time.
Think of Coast FIRE like planting a tree. Once the tree is big enough, you don't need to water it anymore - it can survive on its own. Your retirement savings work the same way. When you have enough money saved, it will grow by itself through compound interest until you're ready to retire.
How Coast FIRE Works
To reach Coast FIRE, you need to save a certain amount of money based on three main things. First, how much money you want to spend each year when you retire. Second, how many years until you plan to retire. Third, how much your investments will grow each year.
For example, if you want to spend $40,000 per year in retirement and you're 30 years old planning to retire at 60, you might need about $200,000 saved today to coast. This money would grow for 30 years without you adding anything more to it.
