The core idea
FIRE means building enough invested savings that the returns can cover your living costs, so you no longer have to work for money. 'Retire early' can mean quitting entirely, or just having the freedom to choose how you spend your time.
The math: the 25x rule
A common FIRE rule of thumb is to save about 25 times your annual expenses. That's tied to the idea of withdrawing roughly 4% a year. If you spend $40,000 a year, the target is around $1,000,000. The 4% figure is a guideline from research, not a guarantee.
Saving rate is everything
What makes FIRE fast isn't a huge income — it's a high saving rate. Saving 50%+ of your income shortens the timeline dramatically, because you're both building savings faster and needing less to live on.
The flavours of FIRE
Lean FIRE means a frugal lifestyle on a smaller number. Fat FIRE means a bigger cushion and more comfortable spending. Barista or Coast FIRE means saving enough early that you can ease off and let compounding finish the job.
The honest trade-offs
FIRE requires real sacrifice now for freedom later, and the math depends on market returns that aren't guaranteed. Healthcare, inflation, and a long retirement add risk. It's not for everyone — but even 'slow FIRE' habits (high saving rate, low-cost investing) help anyone.
