Semi-retirement with side income · Updated 2026

How Barista FIRE Works

Barista FIRE is a hybrid approach: you leave your full-time career but continue working part-time to cover some expenses. Only the gap between your expenses and side income needs to be covered by your portfolio.

For example, with $40,000 annual expenses and $20,000 from part-time work, you only need $500,000 invested (at 4% withdrawal) instead of $1,000,000. This can shave 5-10 years off your FI timeline.

Portfolio Needed at Different Side Income Levels ($40K expenses, 4% WR)

$10,000/year $30,000 $750,000 25% less
$20,000/year $20,000 $500,000 50% less
$30,000/year $10,000 $250,000 75% less
