Can You Really Coast to FIRE? How the Coast FIRE Calculator Helps You Plan Your Retirement

Wondering if you can retire early without adding a dime more? The Coast FIRE Calculator reveals how to let your investments do the heavy lifting for you.

Ever caught yourself wondering, “Can I really stop saving now and still retire early?” If you’re exploring the world of FIRE (Financial Independence, Retire Early), chances are you’ve bumped into the term Coast FIRE. But what does it actually mean — and could you reach it sooner than you think?

This guide unpacks the idea of Coast FIRE, shows where it fits in the broader FIRE spectrum, and walks you through how the Coast FIRE Calculator can help you chart your own course to financial freedom.


What Is Coast FIRE — and Why Should You Care?

If you’re new to the FIRE movement, you’ll quickly find out it’s not one-size-fits-all. There’s lean FIRE vs. fat FIRE, traditional FIRE, barista FIRE, and of course, Coast FIRE.

So, what’s Coast FIRE all about?
It means you’ve piled up enough investments early on that you can hit the brakes on saving for retirement. Your money now works for you — quietly growing on autopilot until you hit your target retirement age. You still cover your everyday expenses with your paycheck, but you no longer need to funnel a chunk of it into your retirement accounts.

Here’s why Coast FIRE matters:

  • It pinpoints exactly how much you need to tuck away today so your money can effortlessly “coast” all the way to retirement.
  • It offers peace of mind—letting you pause the relentless saving grind and savor more flexibility in life.
  • It’s a sweet spot for those craving financial security without sacrificing balance and joy.

Example:
Meet Maya. She’s 30, has $120,000 invested, and dreams of retiring at 60. She plugs her numbers into the Coast FIRE Calculator — and boom! She’s already hit her Coast FIRE number. Now, as long as she leaves her retirement savings untouched, she can focus on living life without the guilt or FOMO.


The Different Types of FIRE: Where Does Coast FIRE Fit In?

You’ve probably heard FIRE called a movement, but it’s really a spectrum of lifestyles and goals. Here are some common flavors:

  • Lean FIRE: Living simply, with a modest retirement budget (think 25,00025,000–40,000/year).
  • Fat FIRE: Aiming for a plush retirement lifestyle (often $80,000+ per year).
  • Barista FIRE: Your investments cover most of your expenses, so you work part-time—maybe as a barista—for extra cash and health benefits, often in a low-stress gig.
  • Coast FIRE: The star of this post — where you save enough early that you can stop contributing and let compound interest do the heavy lifting.

Each path has its perks and trade-offs. What makes Coast FIRE special? It’s about when you can stop saving, not just how much you need. It’s the freedom to just coast.


How the Coast FIRE Calculator Works

So, how do you know if you’ve reached Coast FIRE? Enter the Coast FIRE Calculator.

Here’s the gist:

  1. Enter your current retirement savings.

  2. Set your target retirement age and yearly spending.
    Decide when you want to clock out and how much money you’ll need to live on each year.

  3. Adjust your expected investment return rate.
    The calculator defaults to something like 7% per year, but you can tweak it to match your own outlook.

  4. Review your results.
