Barista FIRE

FU money isn't all-or-nothing. If a little part-time work covers part of your costs, the number you need gets a lot smaller.

How the math works

Barista FIRE number = (annual spending − part-time income) ÷ withdrawal rate. Your portfolio only has to cover the spending your work doesn't, so the number shrinks by 25× the income you keep earning (at 4%). The optional timeline grows your savings plus contributions at your real return until you reach it. Estimates only — not financial advice.
