Barista FIRE means leaving full-time work once your investments can cover part of your spending, and earning the rest from part-time or lighter work. Enter your expenses, the part-time income you expect and your investments to see how much smaller the corpus and the monthly SIP are than for full FIRE.

If part-time work brings in ₹2,40,000 a year in today's money, covering 40% of your spending, you need a Barista FIRE corpus of ₹2,46,50,313 at 45, against ₹4,10,83,855 for full FIRE. That takes a monthly SIP of ₹38,006 for 15 years, ₹32,569 less than full FIRE needs.
When you leave full-time work.

- What it is:
- A Barista FIRE calculator that compares a part-time early retirement with full FIRE.
- What it calculates:
- The corpus needed when part-time income covers part of your spending, the full FIRE number, and the monthly SIP for each.
Key Assumptions
- Expenses and part-time income rise at the same constant inflation rate.
- Part-time income continues for as long as the plan needs it; when it stops, you need the full FIRE corpus or another source.
- The safe withdrawal rate and returns are assumptions; SIP instalments are invested at the start of each month.
- Tax and health insurance after leaving an employer are not modelled separately.
How does the Barista FIRE Calculator work?
Your annual expenses and your part-time income, both in today's rupees, are grown at your inflation rate to the age you want to step back. The calculator assumes your part-time income keeps pace with inflation; if it may not, enter a lower figure.
The full FIRE number is worked out exactly as on our FIRE calculator: expenses at that age divided by the safe withdrawal rate.
The Barista FIRE number applies the same withdrawal rate only to the expenses the part-time income does not cover. If part-time work covers half your spending, you need half the corpus.
Your current investments are grown at the expected return and subtracted from each target, and the monthly SIP is solved with the same start-of-month convention as our SIP calculator, rounded up to the next rupee.
Lean FIRE and Fat FIRE are the same maths with lower or higher spending. Change the expenses to see them, or use the FIRE calculator.
Barista FIRE Calculator formula
Barista number = (E - P) x (1 + f)^t / w; Full FIRE number = E x (1 + f)^t / w
- E
- = annual expenses today
- P
- = annual part-time income today (capped at E)
- f
- = inflation per year, as a decimal
- t
- = years until you step back from full-time work
- w
- = safe withdrawal rate, as a decimal
Required SIP = (target - current corpus x (1 + r)^t) / ([((1 + i)^n - 1) / i] x (1 + i)), with i = r / 12 and n = t x 12.
