Barista FIRE Calculator: quit the full-time, keep the freedom.

Find out when your portfolio can cover most of your living costs — so you can swap the 9-to-5 for easy part-time work, years before full retirement.

What is Barista FIRE?

Barista FIRE is the halfway house. You've saved enough that your portfolio covers most of your living costs — and a calm part-time job fills the gap. You don't wait for full FIRE; you trade the 9-to-5 for flexibility years earlier. Think of it like a relay race: instead of sprinting to the finish line, you hand off part of the burden to lighter work and let your portfolio carry the rest. It sits between Coast FIRE and full FIRE — your portfolio is already working for you, but you still bring in income.

Save $1,000/month and you can switch to part-time work at age 57 — years sooner than full retirement.

Full FIRE needs $990K — part-time work cuts your target by $500.1K.

Every $1,000/mo of after-tax side income ≈ $300K less principal needed.

FAQ

The math, explained.

What if my side income changes year to year? +
Use a conservative average — what you could sustain for years, not a best-case freelance month. The calculator assumes your side income holds steady in today’s dollars. If a year is stronger, you withdraw less; if weaker, you withdraw a bit more.
What happens to my portfolio after I go part-time? +
It stays roughly steady in today’s purchasing power — that’s the 4% rule at work. At ~3.9% real returns and a $20k/yr gap withdrawal, your $500k portfolio drifts to about $468k over 30 years. When Social Security kicks in around 67, your gap (and withdrawals) shrink.
What about bear markets right after I switch? +
This is the unique safety valve of Barista FIRE: if the market drops, you can earn a little more from part-time work and withdraw a little less, giving your portfolio time to heal. Full retirees don’t have that lever. (A formal bear-market stress test is coming in V1.1.)
Where does Social Security fit in? +
Social Security typically kicks in around age 67 — your portfolio bridges the gap until then. After 67, your required withdrawal drops because Social Security covers part of your expenses. The calculator notes this milestone on the chart but doesn’t model exact benefit amounts (they vary by earnings history).
Is this financial advice? +
No. It’s an educational tool based on transparent assumptions. Your real returns will vary. For decisions specific to your situation, speak with a licensed financial advisor.

How this number is calculated

Barista number = (Annual expenses − Annual side income) ÷ Safe withdrawal rate. With $40k expenses, $20k side income, and 4% SWR, that’s $20k ÷ 4% = $500,000. Full FIRE = $40k ÷ 4% = $1,000,000. Semi-retirement trajectory assumes your portfolio grows at the real return rate (~3.9% at 7% nominal, 3% inflation) and you withdraw the annual gap each year-end in today’s dollars — purchasing power stays roughly steady, drifting down ~6% over 30 years, which is exactly what the 4% rule was designed to sustain. The Plan slider uses monthly compounding with i = (1 + realReturn)^(1/12) − 1.

why we use 7% average returns, the 4% rule explained, Barista FIRE guide.

This tool is for educational purposes only and is not financial advice. Estimates are based on the assumptions shown (e.g., 7% nominal returns, 3% inflation, 4% withdrawal rate). Actual investment returns vary. Consider speaking with a licensed financial advisor.
