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.

Frequently Asked Questions

What is the difference between Coast FIRE and regular FIRE?

Regular FIRE means you save enough money to retire right away and live off your savings. Coast FIRE means you save enough money that will grow by itself to support your future retirement, but you still need to work to pay for your current living costs. With Coast FIRE, you can stop saving for retirement but keep working until you reach your retirement age.

How much money do I need for Coast FIRE?

The amount you need for Coast FIRE depends on three things: how much you want to spend each year in retirement, how many years until you retire, and how fast your money will grow. For example, if you want to spend $50,000 per year in retirement in 25 years, and your money grows at 8% per year, you would need about $365,000 saved today to reach Coast FIRE.

Can I still save money after reaching Coast FIRE?

Yes! Reaching Coast FIRE doesn't mean you have to stop saving. It just means you don't need to save anymore to reach your retirement goal. Many people keep saving after Coast FIRE to retire earlier or have more money in retirement. The calculator shows you what happens if you stop saving at Coast FIRE.

What withdrawal rate should I use?

Most people use a 4% withdrawal rate, which means taking out 4% of your savings each year in retirement. This rate has worked well in history to make sure your money lasts. Some people use 3% to be extra safe, while others use 5% if they're willing to take more risk or plan to spend less as they get older.

Should I adjust for inflation?

Yes, you should usually adjust for inflation. Prices go up about 2-3% each year. If you don't adjust for inflation, your buying power will be less when you retire. The calculator lets you choose whether to adjust your contributions and retirement spending for inflation to give you a more accurate picture.

What if I reach Coast FIRE before my target age?

If you reach Coast FIRE early, you have several choices. You can stop saving for retirement and use that money for other things. You can keep saving to retire even earlier. Or you can save less and have more money to spend now while still improving your retirement.

How accurate is the Coast FIRE calculation?

The calculation uses math to project future growth based on the numbers you enter. Real life may be different because investment returns vary each year. The calculator assumes steady growth, but markets go up and down. Use it as a guide to plan, but check your progress regularly and adjust as needed.

What happens if the market crashes after I reach Coast FIRE?

Market crashes can delay your Coast FIRE timeline. If your savings drop a lot, you might need to start saving again or work longer than planned. That's why some people save extra beyond their Coast FIRE number for safety. The good news is you have many years for the market to recover before you need the money.
