What is Barista FIRE
Semi-retirement: withdrawals plus a part-time income cover spending. You leave full-time work, but some earned income is still in the plan. On the defaults, $60,000 of spending minus $25,000 of part-time income is $35,000 a year: $875,000 at 4%, plus the healthcare bridge. Coast FIRE on the same $60,000 spend is the full $1,500,000 discounted back, with no draw until retirement: the Coast FIRE calculator. Healthcare until Medicare is usually the extra bill, which is why this barista FIRE calculator has a premium field. Lean and Fat FIRE are the full-independence numbers on the same scale: Lean and Fat.
The calculator
$60,000 of spending minus $25,000 of part-time income is $35,000 a year, which at 4.0% needs $875,000 plus $133,421 for the healthcare bridge, $1,008,421 in total. Full FIRE without that income is $1,500,000.
How it works
Barista FIRE is the 4% (or other) rule applied to the gap, not to full spending. Coast FIRE is the cousin that keeps working full-time and stops contributing; this one drops to part-time and starts drawing. Healthcare is the present value of net ACA (or other) premiums from the semi-retire age to Medicare, added on top of that capitalised gap. The Barista FIRE health-insurance guide is the long form; the Coast FIRE calculator is the cousin that keeps working full-time. The FIRE calculator is the full version, with no part-time income and the whole spend coming from savings.
Barista FIRE number examples
| Annual spending | $15,000 part-time income | $25,000 part-time income | $35,000 part-time income |
|---|---|---|---|
| $40,000 | $625,000 | $375,000 | $125,000 |
| $50,000 | $875,000 | $625,000 | $375,000 |
| $60,000 | $1,125,000 | $875,000 | $625,000 |
| $80,000 | $1,625,000 | $1,375,000 | $1,125,000 |
Each figure is spending minus part-time income, times 25. Spending $60,000 with $25,000 of part-time pay needs $875,000; full FIRE at the same spending is $1,500,000. Add the healthcare bridge on top if the job does not come with health insurance.
How much part-time income do you need?
Turn the question around when you already know your portfolio: the part-time income you need is your spending minus what the portfolio pays at your withdrawal rate. A $750,000 portfolio at 4% pays $30,000 a year, so spending $60,000 needs $30,000 from work.
| Portfolio | Spending $50,000 | Spending $60,000 | Spending $80,000 |
|---|---|---|---|
| $500,000 | $30,000 | $40,000 | $60,000 |
| $750,000 | $20,000 | $30,000 | $50,000 |
| $1,000,000 | $10,000 | $20,000 | $40,000 |
| $1,250,000 | None (full FIRE) | $10,000 | $30,000 |
Part-time pay is usually a few days a week rather than a career, so the useful check is whether the figure in your row is a job you would actually want. If it is not, the gap has to come from a larger portfolio, lower spending, or a few more years of full-time saving.
Barista FIRE at 30, 40 and 50
The age you leave full-time work changes two things: how many years the portfolio has to last, and how many years of health insurance you pay for before Medicare at 65. Three worked examples at a 4% withdrawal rate:
| Semi-retire at | Spending | Part-time income | Health cover until 65 | Barista FIRE number |
|---|---|---|---|---|
| 30 | $45,000 | $25,000 | Job includes benefits | $500,000 |
| 40 | $60,000 | $25,000 | $12,000 a year | $1,062,465 |
| 50 | $70,000 | $30,000 | $12,000 a year | $1,133,421 |
At 30, a $45,000 budget and a $25,000 job that includes health insurance leave a $20,000 gap, so the number is $500,000. It is the smallest number, but it has to last 60 years or more, so a 3.5% rate is the safer planning figure: $571,429. At 40, the same $35,000 gap as the defaults needs $875,000, and 25 years of marketplace premiums add the rest. At 50, a larger budget is offset by only 15 years until Medicare, and Social Security starts within 12 to 20 years and shrinks the gap from then on. This calculator leaves Social Security out, which is conservative.
Barista FIRE jobs: part-time work with health benefits
The name comes from coffee-shop jobs, and the reason is health insurance: some large employers extend medical coverage to part-time staff who work a minimum number of hours a week. A job like that covers the gap and the biggest bill before Medicare at the same time, so it can be worth more than a better-paid job without benefits. Eligibility rules, waiting periods and hour thresholds change, so check the current plan with the employer before you count on it.
- Retail, coffee and grocery chains. The classic Barista FIRE employer. Some large chains offer health benefits to part-time staff above an hours threshold.
- Schools, universities and hospitals. Public and nonprofit employers often extend benefits to staff working half-time or more, and some add a retirement plan.
- Seasonal work. Tax season, national parks and holiday retail pay for a few months and leave the rest of the year free, but rarely include year-round health cover.
- Consulting or freelancing in your old field. Usually the best pay per hour, with no benefits, so it pairs with a marketplace plan.
- Gig and remote work. Easy to scale up or down, with no benefits and less predictable income.
Without employer coverage, an ACA marketplace plan is the usual answer. The premium tax credit is based on income, so a modest part-time salary plus careful withdrawals can keep the net premium low.
Barista FIRE vs Coast FIRE vs Lean FIRE
- Barista FIRE: leave full-time work now and live on part-time pay plus withdrawals that cover the gap.
- Coast FIRE: keep working full-time to cover today's bills but stop saving, because what you have compounds to your number by retirement. The Coast FIRE calculator finds that point.
- Lean FIRE: full independence on a modest budget, with no work income at all. The Lean FIRE calculator sizes it.
Health insurance on Barista FIRE
Before Medicare at 65, health cover is usually the biggest extra cost, which is why a part-time job that includes health benefits can be worth more than its pay. On an ACA marketplace plan, the premium tax credit depends on modified AGI, so part-time pay and taxable withdrawals decide it, and the credit ends above 400% of the poverty line. The ACA subsidy cliff calculator shows the credit for your income, and the health insurance before Medicare guide compares COBRA, marketplace plans and the other options.
Barista FIRE risks
- The job and the market fall together. A recession is when part-time hours get cut and when the portfolio is down. If the income stops in the same year the market falls, withdrawals jump at the worst moment: a $35,000 gap becomes a $60,000 withdrawal from a smaller portfolio. That is sequence of returns risk with a second trigger, and the sequence of returns risk calculator shows what the order of returns does to a fixed withdrawal.
- Inflation. The calculator works in today's dollars, so it assumes your part-time pay keeps up with prices. If your wage stays flat while prices rise, the gap and the withdrawal grow every year.
- Health insurance. Losing a job with benefits, or a change in marketplace subsidies, can add thousands a year to the gap until Medicare.
- Retirement accounts before 59½. If the gap has to come out of a 401(k) or IRA before 59½, withdrawals usually carry a 10% penalty. The 72(t) calculator sizes penalty-free substantially equal periodic payments, and the rule of 55 covers a 401(k) from an employer you leave in or after the year you turn 55.
- You may not want the job at 60. A plan that needs part-time income until 65 depends on your health and on still wanting to work. Many people plan for the income to stop at a set age, such as 55, and keep saving toward full FIRE by then.
Your cushion is the distance between the Barista number and the full FIRE number. The closer the portfolio gets to full FIRE, the less any of these risks matter.
Would Barista FIRE have worked in the past?
The Barista number is the 4% rule applied to the gap, so while the part-time income holds, its track record is the 4% rule's. We replayed every 30-year retirement since 1928 on a 60/40 stock and bond portfolio with actual inflation: a 4% first-year withdrawal, raised with prices each year, lasted the full 30 years in 94.1% of the 68 start years. Every failure began between 1965 and 1969, a stretch of high inflation and flat markets, with 1965 the worst. Someone who semi-retires at 35 needs the money to last longer than 30 years, which is one more reason to use 3.5% at younger ages. The historical backtest runs your own plan through the same years.
Assumptions
Part-time income is treated as reliable and pre-tax. Healthcare is the net premium after any subsidy, not the sticker price. If that job or that subsidy disappears, you need the full FIRE number. One real return, no fees.
