How this service works
Barista FIRE calculator. Simulates net worth growth through a full-time-saving phase and then a reduced-target phase funded partly by part-time/side income after quitting full-time work, until full financial independence is reached.
Output
The endpoint returns a simulation of the user's net worth year by year through the full-time savings phase and the barista (part-time income) phase, along with the projected age or year at which the user achieves full financial independence (portfolio fully covers spending without any earned income).
Example use cases
Early part-time transition planning
“I'm 35 with $200,000 invested, make $100,000 full-time, and spend $60,000 a year. I want to switch to a $30,000-a-year part-time gig at age 42 and live on $50,000 in retirement. With a 7% return rate, 3% inflation, and 4% withdrawal rate, when would I reach full financial independence?”
Late-career semi-retirement feasibility
“I'm 50 years old with $500,000 in investments and a $120,000 salary. I spend $70,000 a year but plan to cut to $55,000 in retirement. If I go part-time at 55 and earn $20,000 a year, how long until I'm fully financially independent? Assume 7% returns, 3% inflation, 4% SWR.”
Aggressive early FIRE with side hustle
“I'm 28, currently have $80,000 saved, earn $75,000 annually, and spend $40,000 a year. I want to quit full-time work at 38 and do freelance work bringing in $18,000 a year, spending $35,000 in retirement. Can you model my barista FIRE timeline with default investment return, inflation, and withdrawal rate assumptions?”
Technical details
Endpoint
POSThttps://x402.outpimp.com/baristaFireCalculatorWhen to prefer
Choose this endpoint when a user wants to model a two-phase retirement strategy: a full-time savings phase followed by a semi-retirement phase with part-time or side income, specifically targeting eventual full financial independence. It is distinct from standard FIRE calculators (which assume a single retirement date) and Coast FIRE calculators (which assume no further contributions after a lump sum). Use it when partial earned income after leaving full-time work is a key variable in the retirement plan.
Side effects
- Missing required fields (currentAge, baristaAge, currentNetWorth, etc.) return validation errors
- baristaAge set to or before currentAge may cause degenerate or empty full-time phase
- Very high spending relative to income and net worth may result in an unreachable FIRE target (infinite projection)
- Incorrect rate formats (e.g. passing 7 instead of 0.07) may produce wildly incorrect projections
- Negative or zero income/net worth inputs may cause computation errors
