Barista FIRE Calculator
Estimate the portfolio you need when part-time income covers part of your retirement spending.
Quick answer
Barista FIRE means your portfolio covers only the spending gap after part-time income. Formula: (annual spending - part-time income) divided by withdrawal rate. Use conservative rates like 3.5% for long horizons; 4% is usually treated as a 30-year baseline.
Barista FIRE depends on continued part-time income. Model interruptions, lower wages and healthcare costs. If your retirement may last 40+ years, many plans start around 3.5% instead of 4%.
