Barista FIRE Calculator
Semi-retire early: a part-time income lowers the portfolio you need. Enter your expected earnings to find your Barista FIRE number and semi-retirement age — free and instant.
Barista FIRE is semi-retirement: you keep a small part-time income to cover everyday costs, so your portfolio only needs to fill the remaining gap — dramatically reducing the amount you need to save.
See the formula & example
Barista FIRE number = (annual spending − part-time income) ÷ safe withdrawal rate. At $42,000 spending, $24,000 part-time income, and a 4% SWR, your target is just $450,000 — half of full FIRE. Enter your numbers above to see your personal Barista FIRE target.ⓘ Educational estimates based on your inputs — not financial advice.
How Barista FIRE works
Barista FIRE uses the standard FIRE formula but subtracts your part-time income before calculating how much your portfolio must cover. With a 4% withdrawal rate (Rule of 25), every $1,000/yr of part-time income reduces your required portfolio by $25,000.
The core formula: Barista FIRE number = (annual spending − part-time income) ÷ safe withdrawal rate. If you spend $40,000/yr, earn $20,000/yr part-time, and use a 4% SWR, your target is just $500,000 — half of what full FIRE would require at the same spending level.
Barista FIRE worked example
Alex is 32, has $60,000 invested, saves $22,000/yr, and spends $42,000/yr. He wants to semi-retire and work part-time for $24,000/yr. His portfolio only needs to cover $18,000/yr ($42k − $24k). At a 4% SWR, his Barista FIRE number is $450,000. With his current savings rate and 7% real returns, he reaches that target by age 39 — roughly 6 years sooner than full FIRE at $1.05M.
Barista FIRE vs other FIRE types
| Strategy | What you need | Typical portfolio target | Best for |
|---|---|---|---|
| Barista FIRE | Investments + part-time income | (Spending − PT income) × 25 | Those who want flexibility before full retirement |
| Coast FIRE | Early lump-sum, then coast | Full target ÷ growth factor | High early savers who want to slow down mid-career |
| Lean FIRE | Full portfolio, low spend | ~$25k/yr × 25 = $625k | Minimalists comfortable with frugal living |
| Standard FIRE | Full portfolio, typical spend | ~$40k/yr × 25 = $1M | Most people targeting middle-class lifestyle |
| Fat FIRE | Full portfolio, high spend | ~$100k/yr × 25 = $2.5M | High earners wanting no lifestyle compromises |

Barista FIRE — frequently asked questions
What is Barista FIRE?
Barista FIRE is a semi-retirement strategy: you leave your full-time career but keep a small part-time or side income (like a barista job — hence the name) that covers day-to-day expenses. Your investments only need to cover the remaining gap, so your required portfolio is much smaller than full FIRE.
How does part-time income affect my FIRE number?
Each dollar of annual part-time income reduces the amount your portfolio must generate by one dollar. At a 4% withdrawal rate, $20,000/yr of part-time income cuts your required portfolio by $500,000 — from $1M (full FIRE at $40k/yr spending) down to just $500k.
How much do I need for Barista FIRE?
It depends on your spending and part-time income. If you spend $40,000/yr and earn $20,000/yr part-time, you only need $20,000/yr from your portfolio — a Barista FIRE number of $500,000 at 4%. Use the calculator above with your actual numbers.
Is Barista FIRE the same as Coast FIRE?
No. Barista FIRE relies on part-time income to reduce your portfolio target. Coast FIRE relies on having invested enough early that growth alone covers your full number by traditional retirement — no part-time work required. They are complementary strategies, not the same thing. Many people pursue both: coast to a number, then do part-time work until the portfolio fully matures.
What counts as part-time income for Barista FIRE?
Any reliable income you plan to earn after leaving full-time work: a part-time job, freelance work, consulting, a side business, or gig work. The key is that it's sustainable without depending on it growing — enter a conservative estimate in the calculator, not your best-case scenario.
Does Barista FIRE work with Lean or Fat spending levels?
Yes. Barista FIRE is a strategy that works at any spending level. If you spend $60,000/yr (approaching Fat FIRE territory) and earn $25,000/yr part-time, your Barista FIRE number is ($60k − $25k) ÷ 0.04 = $875,000. See the Fat FIRE calculator for high-spend scenarios or Lean FIRE for frugal planning.
