Barista FIRE
Leaving full-time work for part-time or lower-stress work whose income covers part of your spending, so your portfolio only has to fund the gap.
How Ember models it
A barista overlay carries a part-time annual income figure and the age window it runs from and to. The engine reduces your annual spend target by that income and re-solves the FIRE date on the reduced figure. Because required pot is directly proportional to spend on the SWR basis, a barista income that covers a third of your annual spend shrinks the required pot by roughly that same third.
One thing to know
This is explicitly a Phase-1 model, and the engine's own code comment says so plainly: the barista income currently reduces the required spend across the FULL retirement horizon in the calculation, not just the specific years you actually plan to work the part-time job. A more refined, window-specific version is a known fast-follow that hasn't been built yet. Read today's adjusted figure as most accurate when your barista window runs close to your full retirement, and increasingly approximate the shorter that window is relative to the whole horizon.
Reading the adjusted number
The worked example below shows the adjusted required pot next to the full-spend figure it's discounted from, so you can see directly how much a given part-time income is worth toward your target — and, by the same logic, how much a shorter or less reliable barista window is worth less than the model currently credits it for.
Barista FIRE vs a real job change
The model doesn't distinguish between a genuine career change, freelance work, or a hobby business that happens to pay — it only cares about the income figure and the age window. If the part-time income itself is uncertain (client work drying up, seasonal demand), treat the barista-adjusted number as the optimistic case and the full-spend number as the floor to plan around.
Worked example
A $15,000/yr part-time income against a $40,000/yr spend
Full-spend required pot
US$1,000,000
Barista-adjusted required pot
US$625,000

Across borders
Part-time income earned locally after an international move is typically taxed where you're working, which isn't necessarily the same jurisdiction the rest of your plan's tax gross-up is anchored to — treat a cross-border barista income figure as pre-tax unless you've separately accounted for tax where the work happens.
Common questions
Is Barista FIRE the same as Coast FIRE?
No — they overlap but aren't the same. Barista FIRE permanently offsets some of your spending with ongoing part-time income; Coast FIRE is about no longer needing to add new contributions and letting existing savings grow to the target on their own.
Does the part-time income need to be guaranteed?
The model treats it as a fixed, reliable input. If the part-time work itself is uncertain, treat the barista-adjusted number as an optimistic case and the full-spend FIRE number as your conservative floor.
Why does the model reduce spend over the whole horizon instead of just the barista years?
It's a known Phase-1 simplification (see above) — the honest read today is that the adjusted figure is most reliable when your barista window covers most of your retirement, and increasingly approximate the shorter that window is relative to your full horizon.
