🔥 Financial Independence (FIRE) · Lesson 4 of 7 · 7 min
Lean, Fat, Coast & Barista FIRE
🔥 Turns out 'financial independence' comes in flavors, like there's a whole menu. Some people want a Ferrari retirement; others are thrilled with a paid-off cabin and a garden. Knowing which one you're chasing changes your number — and your plan — completely.
💡 Key idea
Lean = frugal/small number; Fat = comfortable/big number; Coast = front-load early then let it ride; Barista = part-time work + investments.
🧠 Why it matters
Same idea, different sizes. LEAN FIRE: a frugal version — a smaller number supporting a minimalist lifestyle. FAT FIRE: a bigger number that funds a comfortable, no-compromises life. COAST FIRE: the sneaky-powerful one — you front-load investing early, and once your nest egg is big enough that compounding ALONE will grow it to your goal by traditional retirement age, you stop adding new money and just cover today's bills. You're 'coasting.' BARISTA FIRE: a hybrid where part-time or lighter work (often kept for the health insurance) covers current expenses while your investments grow untouched. There's no 'right' flavor — only the one that matches the life you actually want.
🌍 In the real world
💡 A 30-year-old invests hard for a few years, hits 'Coast FIRE,' and stops adding new money. They switch to a lower-stress job that just covers the bills — and compounding quietly carries that existing portfolio to a full retirement by 60. They bought freedom now without being 'done.'
📌 Takeaways
- Lean (frugal) vs Fat (comfortable) = different target sizes
- Coast FIRE: save enough early, then let compounding finish the job
- Barista FIRE: light/part-time work covers bills while investments grow
✅ Test yourself
What is 'Coast FIRE'?
- Living on the coast
- You've invested enough early that compounding alone reaches your goal — you just cover current bills
- Retiring with $10M
- Never working again at 25
Answer: B · You've invested enough early that compounding alone reaches your goal — you just cover current bills
Once your nest egg will grow to your target on its own, you stop adding and just cover today's expenses.

- Your job title
Answer: B · The size of the number / the lifestyle it funds
Lean funds a frugal life with a smaller number; Fat funds a comfortable life with a bigger one.
'Barista FIRE' typically means...
- Owning a coffee shop

- Drinking less coffee
- Full early retirement with zero work
Answer: B · Part-time or lighter work covers current costs while investments grow untouched
