Coast FIRE Isn't Retiring Early. It's Deciding You're Done Adding to the Pile
You don't need a beach and a laptop to hit this. You just need to stop feeding the number and let it grow on its own.

Everyone talks about early retirement like it's a finish line you sprint toward, cut your spending to nothing, work a second job, retire at 35 with a beach and a laptop. That's regular FIRE, and it requires a specific kind of intensity most people don't actually want to sustain for fifteen years straight. Coast FIRE is the quieter version, and it's the one that's actually realistic for someone earning a normal income.
The idea is simple. Once you've saved enough that compound growth alone will get you to your retirement number by a normal retirement age, you don't have to keep adding to that account at the same aggressive pace. The pile keeps growing on its own. You can drop to a lower-stress job, work fewer hours, or just stop feeling like every paycheck needs a chunk carved out for retirement, because that job is already done.
This matters right now because a lot of people are burned out on the idea that financial progress only counts if it's aggressive. Coast FIRE reframes the goal. It's not "save as much as possible forever." It's "hit the number once, then let time do the rest." That's a very different relationship with money than the one most budgeting advice assumes.
Here's the rough math. Take your retirement number, the amount you'd actually need at 65. Then work backward: given the years you have left and a reasonable growth rate, what balance today would get there untouched. If your current retirement savings are close to that number, you're already coasting and didn't know it. If you're nowhere near it, that's not a failure, it's just information about how many more years of active saving you actually need, not forever, just until you hit the number.
The relief in Coast FIRE isn't the beach. It's the moment you realize you don't have to keep sprinting toward retirement on top of everything else you're already carrying. You just have to have already run far enough.

Quick Answers
What is Coast FIRE?
It's the point where you've saved enough that, left alone to grow with compound interest, your investments will hit your retirement number by a normal retirement age without you adding another dollar. You still work, you just aren't required to keep funding retirement on top of it.
How is this different from regular FIRE?
Regular FIRE is about quitting work entirely, early, which requires a much bigger number and usually a lot of deprivation to get there fast. Coast FIRE only asks you to hit the number once. After that, growth does the rest while you keep working normally.
How do I know if I've hit my Coast FIRE number?
Take what you'd need at retirement age, then work backward using a compound growth estimate to see what balance today would get there untouched. If your current retirement savings are near or past that number, you're coasting.
