Coast Fire- sometimes written as Costfi-is a smart way to achieve financial freedom without saving forever. This means that you have already saved so much money that if you leave it alone to grow (such as landing on a bike), it will be enough for you to retire at a traditional age – even if you stop saving now.

You still work to meet your existing expenses, but you no longer need to save aggressively.

For example:
If you are 30 years old and you have savings of $150,000, then that money can grow automatically and be sufficient by the age of 60 – even if you never save another dollar. This is the Coast Fire.

Coast Fire Calculator helps you find out how much money you need for retirement later. It takes all the annuals you need at your current age, retirement age, expected investment return, and retirement and then tells you the amount of savings according to today’s need.

It’s like a shortcut map to financial independence.

Here’s what it tells you:

• When you might hit Coast FIRE status
• How much do you need to save today to stop saving for retirement
• If you’re ahead, behind, or on track for CoastFI

A necessary step that clarifies your coast fire number on this journey. This means the total amount you will need to invest to have it grow so that it is enough for your retirement and then rest on its own.

The calculation hinges on the compound interest formula:

Where:

• AAA = Future value of the investment
• PPP = Present value or initial principal
• rrr = Annual growth rate (as a decimal)
• ttt = Time in years

To find your Coast FIRE number (PPP), rearrange the formula:

Example Calculation:

Suppose you aim to have $1,000,000 by retirement, expect an annual growth rate of 7% (0.07), and have 20 years until retirement:

This means you’d need approximately $258,419 invested today to reach $1,000,000 in 20 years without additional contributions.

Say you’re 28 years old and want to retire at 60. You want $50,000 per year in retirement, and you expect your investments to grow 7% each year.

The calculator might say: “You need $110,000 saved today to coast into retirement at 60.”

If you already have that much saved, you’re free to stop saving more and just maintain your lifestyle. That’s the power of Coast FIRE.

Embracing the Coast FIRE approach offers several advantages:

It removes the stress of “Am I doing enough?” because the numbers show you the truth.

Although Coast Fire is attractive, it is necessary to be aware of possible challenges:

Regular reviews and adjustments of your strategy ensure that you stay on the right path despite these uncertainties.

Coast FIRE can be combined with other financial approaches to enhance its effectiveness:

By combining these strategies, you can make a financial plan that aligns with your personal goals and values.

1. Coast FIRE vs. Traditional FIRE

• Traditional Fire requires aggressive savings and frugality to retire as soon as possible.
• Coast Fire allows individuals to prevent aggressive savings after making sufficient investments; instead, it focuses on covering current expenses, allowing investment to increase.

2. Coast FIRE vs. Barista FIRE

• Barista fire involves doing low-stress, part-time jobs to meet the expenses of living during the increase in investment.
• The coast fire is more passive, as it assumes that you do not need additional savings beyond your initial investment.

3. Coast FIRE vs. Lean FIRE & Fat FIRE

• Lean FIRE requires extreme frugality to retire with a minimal budget.
• Fat FIRE involves saving enough to maintain a luxurious retirement lifestyle.
• Coast FIRE is in between, balancing work, savings, and investment growth.

Yes, you can only if you’re honest with your plan.

If the calculator shows you need $120,000 to coast, and you have $130,000, you’re covered. You still need to work to cover your regular bills, but your retirement money is set.

Still, life happens. Markets change. So even if you hit Coast FIRE, it’s smart to:

• Review your plan every year
• Keep your spending in check
• Don’t dip into your retirement accounts early
