Coast FIRE vs Barista FIRE: which fits you?

By · Updated

In short: Coast FIRE means saving enough early that growth alone can reach your retirement target, so you only need to cover current costs. Barista FIRE means living partly on your portfolio and partly on part-time income.

Not everyone wants to grind until they hit a full 25×-spending number. Two popular middle paths, Coast FIRE and Barista FIRE, let you ease off sooner. They sound similar, but they rest on different ideas and carry different risks. Here's how I'd think about choosing.

Coast FIRE: let compounding finish the job

You've reached Coast FIRE when your current investments, with no new contributions, could plausibly grow into your full retirement target by a traditional retirement age. From then on, you only need to earn enough to cover current living expenses. You stop saving for retirement and “coast.”

A simple way to estimate your Coast number is to discount your future target back to today:

Coast number ≈ FIRE number ÷ (1 + real return)years until retirement

For example (illustrative only): with a $1,000,000 target in today's dollars, 25 years to go, and an assumed 5% real return, the Coast number is about $1,000,000 ÷ 1.0525, or roughly $295,000. If you have that invested, growth alone could get you there if returns cooperate.

Who it suits: people in their 30s or 40s with a good start who want to take a lower-paying but more meaningful job, start a business, or cut hours, while still working full-time-ish.

Watch out for: the math is very sensitive to the assumed return and time horizon. A few weak market years, or deciding you want to retire earlier after all, can leave you short. Many people keep a cushion above their Coast number or keep contributing a little.

Barista FIRE: part portfolio, part paycheck

Barista FIRE means you've stopped full-time career work and live on a combination of portfolio withdrawals and part-time or flexible income. The name comes from the idea of working at a coffee shop partly for the health benefits, but the work can be anything: consulting, seasonal work, tutoring, a small business.

The target is lower than full FIRE because your job covers part of your spending. Roughly:

Barista number ≈ (annual spending − expected part-time income) ÷ withdrawal rate

Illustration: spending $50,000, earning $20,000 part-time, and using a 4% withdrawal rate gives ($50,000 − $20,000) ÷ 0.04 = $750,000, versus $1,250,000 for full FIRE.

Who it suits: people who are ready to leave their career now, enjoy some work, and want a portfolio that's already supporting them.

Watch out for: your plan depends on that income continuing. Health issues, a weak job market, or simply losing interest can change things. Have a plan B.

The key difference

  • Coast FIRE: you're not withdrawing. Work pays all current bills; the portfolio is left to grow.
  • Barista FIRE: you are withdrawing. The portfolio and part-time work share the load starting now.

Coast is about when you stop saving; Barista is about when you start spending your portfolio.

Tax considerations

Both paths usually mean lower earned income than your career peak, which opens tax planning opportunities:

  • Lower brackets can make Roth contributions or Roth conversions more attractive than pre-tax contributions. See Roth conversion ladders explained.
  • Self-employment (common in Barista FIRE) brings self-employment tax, but also access to a SEP IRA or solo 401(k) and potentially the qualified business income deduction. Rules and limits change, so check the current year.
  • Earned income keeps IRA eligibility. You generally need earned income to contribute to an IRA, so part-time work lets you keep funding tax-advantaged accounts.
  • Estimated taxes may be needed if you're self-employed or withdrawing from investments without withholding.

The health insurance angle

This often decides the question. A Coast FIRE worker in a full-time job usually has employer coverage. A Barista FIRE worker may have it only if the part-time employer offers benefits; otherwise they're likely on an ACA marketplace plan, where income matters. Under 2026 rules, premium tax credits phase out entirely above 400% of the federal poverty line, so wages plus withdrawals need to be planned together. See Health insurance before Medicare.

So which fits you?

  • Choose Coast if you like (or can tolerate) working most of the week, want a lower-stress or more meaningful job, and have a long time horizon.
  • Choose Barista if you want to leave full-time work soon, are comfortable relying on a smaller paycheck, and have a plan for health coverage.
  • Many people do both in sequence: coast for a while, then shift to Barista, then fully retire.

Run your own numbers with the FIRE number calculator. For a Barista estimate, subtract your expected part-time income from annual spending.

Frequently asked questions

What is Coast FIRE?

Coast FIRE is when your investments are large enough that, with no further contributions, they could grow to your full FIRE number by your target retirement age. You still work to cover current spending.

What is Barista FIRE?

Barista FIRE means your portfolio covers part of your spending and part-time work covers the rest, often including access to health insurance.

How do I estimate my numbers?

Use the FIRE number calculator. For a rough Barista estimate, subtract expected part-time income from your annual spending before calculating.
