Barista FIRE means quitting full-time work once your investments can cover the part of your spending that a part-time job doesn't. Enter your spending, expected part-time income and savings to see your Barista FIRE number, how long until you get there, and how it compares with full FIRE.

How to use the Barista FIRE Calculator
Enter your age, investments and monthly saving while you still work full-time.
Enter yearly spending in today's money, including health insurance.
Enter the after-tax income you expect from part-time or flexible work.
Pick a withdrawal rate and real return, and optionally the age you'll stop working entirely.
Read your Barista FIRE number, the time to reach it and the projection chart.
The Barista FIRE formula
Barista FIRE splits your retirement spending into two parts: what part-time work pays and what your investments must pay. Only the second part needs a portfolio behind it, which is why the Barista FIRE number is much smaller than the full FIRE number.
Spending gap = annual spending − part-time income Barista FIRE number = spending gap ÷ withdrawal rate
Example: you plan to spend $48,000 a year and expect $24,000 after tax from a part-time job. The gap is $24,000, so at a 4% withdrawal rate the Barista FIRE number is $24,000 ÷ 0.04 = $600,000, half of the $1,200,000 needed to stop working altogether.
If you plan to stop part-time work at a set age, the portfolio has to cover the gap and still grow to the full FIRE number by then. The calculator solves for the balance needed when you go part-time: (FIRE number + gap × ((1 + r)n − 1) ÷ r) ÷ (1 + r)n, where r is the real return and n the years of part-time work.

Every $1,000 of yearly part-time income lowers the number by $25,000 at a 4% withdrawal rate (and by about $28,600 at 3.5%).
Tips for planning Barista FIRE
Price health insurance honestly. If the part-time job doesn't offer coverage, add marketplace premiums and out-of-pocket costs to your spending.
Keep a cash buffer. One to two years of the spending gap in cash helps you avoid selling investments after a market drop.
Plan for the part-time job ending. Use the optional stop age to test whether your portfolio can grow into full retirement.
Remember later income. Social Security or a pension at 62 to 70 reduces what the portfolio has to cover later in life; this calculator conservatively leaves it out.
Frequently asked questions
What is Barista FIRE?
Barista FIRE is a form of early semi-retirement: you leave full-time work once your investments can pay for part of your living costs, and a lower-stress part-time or flexible job pays the rest. The name comes from the idea of working at a coffee shop partly for the income and partly for benefits such as health insurance.
How do you calculate the Barista FIRE number?
Subtract your expected part-time income from your annual spending to get the gap your portfolio must cover, then divide that gap by your withdrawal rate. For example, ($48,000 − $24,000) ÷ 0.04 = $600,000, compared with $1,200,000 for full FIRE.
How is Barista FIRE different from Coast FIRE?
With Coast FIRE you stop adding to retirement savings but your job still pays all current expenses, so the portfolio is never touched. With Barista FIRE you already withdraw from the portfolio to cover part of your spending, and part-time work covers the rest.
What if I want to stop working completely later?
Enter the age you plan to stop part-time work. The calculator then finds the balance you need when you go part-time so that, after withdrawing the spending gap each year, the portfolio still grows to your full FIRE number by that age.
Should part-time income be before or after tax?
Use after-tax income, because spending is what you actually pay out. Also include costs a part-time job may not cover, such as health insurance premiums, in your annual spending.
Why use a real return instead of a nominal return?
Spending and part-time income are entered in today's money, so the return should be after inflation too. A 7% nominal return with 2.5% inflation is roughly a 4.4% real return.
Is the result guaranteed?
No. It is a projection based on a steady average return. Poor market years early in semi-retirement, losing part-time income or higher spending can change the outcome, so many people add a safety margin.
