    Reaching your Barista FIRE number

    Green is your portfolio; the indigo line is the smaller Barista FIRE target. Where they meet, part-time income can carry the rest.

    How your contribution changes the date

    Saving more each month moves your Barista FIRE age forward — see exactly how much.

    The exact formula — with your numbers

    Part-time income lowers what your portfolio must cover, so the FIRE number shrinks:

    Barista = Expenses − Part-time incomeSWR

    SWR = safe withdrawal rate. We then simulate your contributions in real dollars to find when your portfolio reaches this smaller number.

    How to use this Barista FIRE calculator

    1. Enter your spending and expected part-time income. The gap between them is what your portfolio has to fund.
    2. Add what you have invested and save monthly. The tool finds when you reach the smaller Barista number.
    3. Compare to full FIRE. See how many years of full-time work part-time income buys back.

    What Barista FIRE actually means

    Barista FIRE sits between working forever and full financial independence. Instead of saving until your portfolio covers all of your expenses, you save until it covers the part your part-time income won't — then you downshift to a lower-stress job (the name comes from Starbucks offering health benefits to part-time staff). Because you only need to fund the gap, your target can be hundreds of thousands of dollars lower, pulling your escape from full-time work years closer. If you'd rather stop saving but keep your current job, see our Coast FIRE calculator instead.

    Frequently asked questions

    Does part-time income include health insurance value?

    This tool models cash income only. If your part-time job provides health insurance, that's an additional benefit — you could lower your "annual spending" input by your expected premium savings to reflect it.

    What's the difference between Barista and Coast FIRE?

    Coast FIRE: stop saving, keep working full-time, let investments grow to your full number. Barista FIRE: keep saving to a smaller number, then switch to part-time work that covers the rest. Barista gets you out of full-time work sooner.

    Is the 4% rule safe for a long semi-retirement?

    The 4% guideline came from ~30-year retirements. For a longer horizon many people use 3.25–3.5% to be safe. Lower the withdrawal rate here to see how it raises your target.

    Method & sources

    • Calculation: Barista number = (expenses − part-time income) ÷ SWR; full FIRE = expenses ÷ SWR; contributions simulated monthly in real dollars. Verified against an independent test suite.
    • The safe withdrawal rate is a planning guide (Trinity study), not a guarantee, and shorter for longer horizons.
