What Is Barista FIRE?
Barista FIRE is a flexible approach to early retirement where you:
- Semi-retire early (often in your 30s, 40s, or 50s)
- Work part-time (like a barista, consultant, or freelancer) to cover some expenses
- Let your investments cover the rest of your living costs
- Enjoy more freedom without the pressure of full-time work
This approach is more accessible than traditional FIRE because your savings target is lower — you only need to cover the gap between your expenses and your part-time income.
The Barista FIRE Formula
The Barista FIRE formula calculates how much you need invested so your portfolio covers the gap between your expenses and part-time income.
Step 1: Calculate Your Full FIRE Number (No Part-Time Work)
Full FIRE Number = Annual Expenses ÷ Safe Withdrawal Rate
Using the 4% rule: if you need $50,000 per year, your full FIRE number is $1,250,000.
Step 2: Calculate Your Barista FIRE Number (With Part-Time Work)
Barista FIRE Number = (Annual Expenses – Annual Part-Time Income) ÷ Safe Withdrawal Rate
Example:
| Variable | Value |
|---|---|
| Annual Expenses | $50,000 |
| Part-Time Income | $25,000 |
| Expenses Gap | $25,000 |
| Safe Withdrawal Rate | 4% |
| Barista FIRE Number | $25,000 ÷ 0.04 = $625,000 |
You need $625,000 invested, not $1,250,000 — that’s half the savings target!
Barista FIRE vs Other FIRE Approaches
