Barista FIRE means quitting full-time work once your portfolio plus a low-stress part-time job (often one with health benefits) can cover your life. Because part-time income offsets withdrawals, your required nest egg shrinks dramatically — and your escape date moves up by years. All math runs privately in your browser.
Your full FIRE number is annual spending ÷ safe withdrawal rate. For Barista FIRE, part-time income covers part of your spending, so the portfolio only needs to fund the remainder: Barista Number = (Spending − Part-Time Income) ÷ SWR. Earning $24,000/yr part-time with $50,000/yr spending at a 4% SWR cuts the requirement from $1.25M to $650k — nearly in half.
The most common reason in the U.S. is health insurance: employers offering part-time benefits can bridge the gap to Medicare at 65. The second reason is psychological — a gentle glide path out of full-time work beats a cliff-edge. The trade-off: you're committing to some employment for years, and if part-time work becomes impossible, your plan needs slack. Stress-test the full picture with our Monte Carlo planner.
