Barista FIRE Calculator
If a part-time job covers some of your spending, your investments only have to fund the rest, which means you need far less invested. Enter your spending and your part-time income to see your Barista FIRE number and how much smaller it is than full financial independence.

What your Barista FIRE number means
The big number is the portfolio you need when your part-time income covers part of your spending and your investments fund only the remaining gap. The breakdown shows that gap and how much smaller this target is than full FIRE. Because every bit of reliable part-time income removes a multiple of itself from the portfolio you need, even modest earnings cut the target sharply.
Barista FIRE is the most practical FIRE variant for someone leaving a demanding job, because it does not require the full number. It lets you swap intense full-time work for lighter, chosen work, often kept partly for the health benefits, while your savings quietly carry the rest.
Estimating your part-time income
- Use income you could reliably sustain. Barista FIRE depends on the part-time earnings continuing, so base it on work you could do steadily for years, not a best-case freelance month.
- Enter it after tax. Use the income you would actually keep, since that is what offsets your spending. Part-time earnings may be taxed differently, so estimate conservatively.
- Value the benefits, not just the pay. If the part-time role provides health cover, that removes one of the biggest costs of leaving full-time work. Lower your spending figure to reflect cover you no longer buy yourself.
- Have a plan for losing the income. If the part-time work stops, your portfolio must cover everything. Keep a buffer or the flexibility to spend less, so the plan survives a gap. The runway calculator sizes that buffer.
A Barista FIRE plan, worked through
Mara spends 3,500 a month and expects to keep 1,500 a month from light part-time work, using the 4 percent rule. Her portfolio only needs to cover the 2,000 monthly gap, which is 24,000 a year, so her Barista FIRE number is 24,000 divided by 0.04, which is 600,000. Full FIRE on her 42,000 of spending would need 1,050,000, so the part-time income saves her 450,000 of investing.
With 200,000 invested and 2,000 a month going in at a 5 percent real return, she reaches the 600,000 Barista target in roughly 12 years, against about 20 for full FIRE. The part-time income, not extra saving, does most of the work.
How the Barista FIRE number is calculated
The Barista FIRE number equals your annual spending minus your annual part-time income, divided by your safe withdrawal rate. That is the portfolio needed to fund only the gap your part-time earnings do not cover. The comparison shows full FIRE, which is your whole annual spending divided by the same rate. If your part-time income covers all your spending, the portfolio target falls to zero. The years estimate grows your current investments and monthly contributions at the real return you choose until the balance reaches the Barista target. It assumes the part-time income and a steady return continue, which real life may not, so treat it as a guide. Full assumptions on the methodology page. Educational estimate, not financial advice.
What Barista FIRE plans miss
Assuming the part-time income is permanent
If it stops, you need your full FIRE number, not the Barista one. Keep a buffer and a fallback for losing the work.
Overstating what you would keep
Tax and inconsistent hours reduce part-time pay. Use a conservative, after-tax figure you could sustain for years.
Forgetting why health cover matters
For many, the part-time job is really about health benefits. If yours does not provide them, add the cost back into your spending. Price cover
Treating it as full retirement
Barista FIRE still involves working. It buys freedom from full-time intensity, not freedom from work entirely, so plan for the hours.

Frequently asked questions
What is Barista FIRE?
Barista FIRE is a form of semi-retirement where a part-time job covers some of your living costs, so your investment portfolio only has to fund the rest. The name comes from taking an easy part-time role, sometimes for the health benefits, while your savings cover the gap. It needs a much smaller portfolio than full financial independence.
How do I calculate a Barista FIRE number?
Subtract your expected part-time income from your annual spending to get the gap your portfolio must cover, then divide that gap by your safe withdrawal rate. At a 4 percent rate, if you spend 40,000 a year and earn 16,000 part-time, your portfolio covers 24,000, so your Barista FIRE number is about 600,000.
Does Barista FIRE include health insurance?
Often that is the point. In the US especially, many people choose a part-time job that offers health benefits, which removes one of the largest costs of leaving full-time work. If your part-time role provides cover, lower your spending figure accordingly before calculating, since you no longer pay for it yourself.
Is Barista FIRE the same as semi-retirement?
They overlap closely. Barista FIRE is a specific version of semi-retirement where part-time earnings plus portfolio withdrawals together cover your spending, letting you leave demanding full-time work much earlier than full FIRE would allow. The label emphasises that the part-time work is light and chosen, not a necessity.
People also ask
How much part-time income do I need for Barista FIRE?
Enough to shrink the gap your portfolio must fund to a level your savings can support. Every 1,000 a month of part-time income removes about 300,000 from the portfolio you need at a 4 percent withdrawal rate. So even modest, steady part-time earnings dramatically lower the Barista FIRE number compared with full FIRE.
What is the difference between Barista FIRE and Coast FIRE?
Barista FIRE uses part-time income now to cover current spending alongside portfolio withdrawals. Coast FIRE means you have enough invested that it will grow to your retirement target without further saving, so you only need a job that covers today's costs. Barista FIRE draws on the portfolio now; Coast FIRE leaves it to grow untouched.
What happens to Barista FIRE if I stop the part-time job?
Your portfolio then has to cover your full spending, which means you would need your full FIRE number, not the smaller Barista figure. Barista FIRE depends on the part-time income continuing, so it is safest when that income is reliable and you have a plan for losing it, such as a larger buffer or the option to spend less.
