Barista FIRE Calculator
Enter your annual expenses and expected part-time income to find your Barista FIRE number.
Barista FIRE is semi-retirement where part-time work covers some of your expenses and your portfolio covers the rest. Your Barista FIRE number is your annual expenses minus your part-time income, divided by your withdrawal rate. It is lower than full FIRE because you do not need the portfolio to cover everything.
How to Use This Calculator
Enter the total you expect to spend each year, then the annual income you expect from part-time or 'barista' work — the kind of lower-stress job that often comes with health benefits. Set your withdrawal rate; 4% is the common starting point.
The calculator returns your Barista FIRE number — the portfolio you need so that your withdrawals plus your part-time income cover your expenses — and, for comparison, the full FIRE number you would need if the portfolio had to cover everything alone.
How the Calculation Works
Full financial independence requires a portfolio big enough that a safe withdrawal covers all your expenses, which is expenses divided by the withdrawal rate — the 4% rule inverted, or 25 times annual expenses at 4%.
Barista FIRE lowers the bar. Part-time income covers part of your spending, so your portfolio only has to cover the gap. Dividing that smaller gap by the withdrawal rate gives a much smaller target, which can bring semi-retirement years closer.
Barista FIRE number = (expenses − part-time income) ÷ withdrawal rate
Worked Example
Suppose your annual expenses are $50,000 and you expect $20,000 a year from part-time work. The gap your portfolio must cover is $30,000. At a 4% withdrawal rate, your Barista FIRE number is 30,000 ÷ 0.04 = $750,000.
Full FIRE, where the portfolio covers all $50,000, would need 50,000 ÷ 0.04 = $1,250,000. The part-time income cuts the target by half a million dollars.
What the Result Means
The Barista FIRE number is how much you need invested before part-time work becomes enough to bridge the rest. It is popular because it can be reached years earlier than full FIRE and often unlocks employer health coverage through the part-time job.
The trade-off is that you keep working, and the plan depends on that income continuing. If the part-time work stops, your portfolio alone may not cover full expenses, so many people treat Barista FIRE as a stepping stone toward full FIRE.
Assumptions and Limitations
- Assumes part-time income continues reliably through semi-retirement
- Uses a simple withdrawal-rate rule; it does not model market swings
- Ignores taxes on both the part-time income and the withdrawals
- The 4% withdrawal rate is a guideline, not a guarantee
Who Uses a Barista FIRE Calculator
People pursuing financial independence use this to find the smaller portfolio they need when part-time or side income covers part of their expenses. It suits anyone planning to downshift to lighter work rather than fully retire, letting a modest paycheck bridge the gap while investments keep growing. Enter your expenses and expected part-time income to see the Barista FIRE and full-FIRE targets side by side.

What is Barista FIRE?
Barista FIRE is a form of semi-retirement where part-time work — classically a coffee-shop job with benefits — covers part of your expenses, so your investment portfolio only needs to cover the rest. It needs a smaller nest egg than full FIRE.
How is the Barista FIRE number calculated?
Subtract your expected part-time income from your annual expenses, then divide by your withdrawal rate. At 4%, a $30,000 gap needs a $750,000 portfolio.
How is Barista FIRE different from full FIRE?
Full FIRE needs a portfolio large enough to cover all your expenses with no work. Barista FIRE leans on part-time income for part of your spending, so the required portfolio is smaller and reachable sooner.
What is a safe withdrawal rate?
Four percent is the common benchmark from the classic research, meaning you withdraw 4% of the portfolio in year one and adjust for inflation. Some choose 3–3.5% to be more conservative.
What are the risks of Barista FIRE?
It depends on the part-time income continuing. If that work ends — by choice, health or the job market — your portfolio alone may not cover full expenses, so keep a margin of safety.
