How It Works

Our Coast FIRE Calculator helps you determine if your current investments are on track to fund your retirement goals without needing further contributions. This powerful tool projects your existing nest egg's growth, revealing if it will reach your desired retirement income by your target age. Understanding your Coast FIRE number by 2026 allows you to make informed decisions about your savings strategy and potentially reduce future financial stress.

The calculator projects your current investment balance forward using a specified annual growth rate until your chosen retirement age. It then calculates the future value needed to generate your desired annual retirement income, assuming a safe withdrawal rate (typically 4%). If your projected investment balance at retirement exceeds the calculated needed amount, you've reached Coast FIRE.

Remember, this calculation relies on estimated growth rates and withdrawal rates, which can fluctuate. Don't forget to account for inflation, as your desired retirement income in today's dollars will be worth less in the future. A common mistake is underestimating healthcare costs in retirement, so factor those into your desired annual income.

Example: Sarah's Coast FIRE Journey

  1. 1 Sarah is 35 years old and has $150,000 invested. She plans to retire at 60 and wants $60,000 per year in retirement. She estimates an 8% annual investment growth rate and a 4% safe withdrawal rate.
  2. 2 The calculator projects Sarah's $150,000 investment growing at 8% annually for 25 years (until age 60) to approximately $1,029,919. To generate $60,000 annually with a 4% withdrawal rate, she needs $1,500,000 at retirement.
  3. 3 Sarah's projected balance of $1,029,919 is less than the $1,500,000 needed. Therefore, Sarah has NOT yet reached Coast FIRE.
  4. 4 This means Sarah needs to continue saving or increase her investment growth to reach her retirement goal. She could explore increasing her current savings, finding ways to boost her investment returns, or adjusting her desired retirement income.

Frequently Asked Questions

What is Coast FIRE?
Coast FIRE is when you have enough invested that compound growth alone will grow it to your full retirement number by your target age, without any additional contributions. You still work to cover living expenses but stop saving for retirement.
How do I calculate my Coast FIRE number?
Divide your target retirement number by (1 + expected return rate) raised to the power of years until retirement. For example, needing $1.5M in 20 years at 7% returns means your Coast FIRE number is about $388,000 today.
What is the difference between Coast FIRE and Barista FIRE?
Coast FIRE means you stop saving for retirement but still work full-time to cover expenses. Barista FIRE means you switch to part-time work, using your portfolio to partially cover the gap between part-time income and expenses.
