How the Barista FIRE Calculator Works
Barista FIRE is a halfway point on the road to financial independence. Instead of saving enough to cover every expense from investments alone, you save enough that a part-time or lower-stress job covers the rest. This calculator finds your Barista FIRE number — the portfolio that, combined with part-time income, funds your lifestyle — and compares it to the full FIRE number so you can see how much sooner you could downshift.
The Formula
Gap = annual expenses − part-time income Barista FIRE number = gap ÷ (withdrawal rate ÷ 100)
For reference, the full FIRE number ignores part-time income:
Full FIRE number = annual expenses ÷ (withdrawal rate ÷ 100)
The withdrawal rate is usually the 4% rule, which is the same as needing 25× the amount your portfolio must cover.
Worked Example
Suppose your annual expenses are $48,000, your part-time net income is $20,000, you use a 4% withdrawal rate, and you currently have $150,000 saved:
- Gap = 48,000 − 20,000 = $28,000 that the portfolio must cover
- Barista FIRE number = 28,000 ÷ 0.04 = $700,000
- Full FIRE number = 48,000 ÷ 0.04 = $1,200,000
- Progress to Barista FIRE = 150,000 ÷ 700,000 = about 21.4%
The part-time income shrinks the target by $500,000 — you reach Barista FIRE far sooner than full FIRE.
| Part-time income | Gap (vs $48k expenses) | Barista FIRE number (4%) |
|---|---|---|
| $0 (full FIRE) | $48,000 | $1,200,000 |
| $20,000 | $28,000 | $700,000 |
| $30,000 | $18,000 | $450,000 |
When Barista FIRE Makes Sense
Barista FIRE suits people who want to leave a demanding career years early but do not mind light work — often for health insurance or social connection. The more your part-time job can reliably earn, the smaller the portfolio you need, so it pays to estimate that income conservatively and keep a margin for years when you cannot work.
Frequently asked questions
What is Barista FIRE?+
Barista FIRE is a semi-retirement strategy where you leave full-time work once your portfolio is large enough to cover your expenses minus the income from a low-stress part-time job. The part-time work, sometimes for benefits like health insurance, fills the gap your investments cannot yet cover.
How do you calculate a Barista FIRE number?+
Subtract your expected part-time net income from your annual expenses to find the gap your portfolio must cover, then divide by your safe withdrawal rate. For example, $48,000 of expenses minus $20,000 of part-time income leaves a $28,000 gap, which at 4% needs $700,000.
How is Barista FIRE different from full FIRE?+
Full FIRE requires a portfolio big enough to cover all of your expenses from investments alone. Barista FIRE only needs to cover the part not paid by your part-time income, so the target is smaller and you can step back from full-time work much sooner.
Is Barista FIRE the same as Coast FIRE?+
No. With Coast FIRE you stop contributing and let existing investments grow to a full retirement number while still working to cover current expenses. With Barista FIRE you actually draw on the portfolio now, using part-time income to bridge the difference.
Why use part-time income in the calculation?+
Because every dollar your part-time job earns is a dollar your portfolio does not have to fund. Including it lowers the gap that withdrawals must cover, which directly reduces the size of the nest egg you need to reach financial semi-independence.
