Barista FIRE Calculator
Barista FIRE combines financial independence with part-time work. Your investments cover part of your expenses, and part-time income covers the rest — meaning you need significantly less saved than full FIRE. If your expenses are $50K/year and you earn $20K part-time, you only need your portfolio to generate $30K/year.
The name comes from the idea of working a low-stress job (like a barista) for benefits and basic income. It's one of the most practical FIRE strategies because it reduces the savings target dramatically while still providing freedom from full-time work. This calculator shows your Barista FIRE number and how much less you need compared to full FIRE.
Your Barista FIRE number is $750,000 — covering the $30,000/yr gap between your expenses and part-time income. That's $500,000 less than full FIRE ($1,250,000).

How to use this calculator
Annual expenses — Your total yearly spending in retirement. Include housing, food, healthcare, insurance, and discretionary spending. Be realistic — this is the foundation of your Barista FIRE calculation.
Part-time annual income — Income from part-time work, freelancing, consulting, or side gigs. This is what makes Barista FIRE work — it reduces the amount your portfolio needs to generate. Include any income you expect to earn consistently after leaving full-time work.
Current savings — Your total investable assets: 401(k), IRA, brokerage, HSA. Don't include your home equity unless you plan to sell and invest it.
Monthly savings — How much you invest each month while working toward Barista FIRE. Include employer 401(k) matches.
Expected real return — Your after-inflation annual return. 7% is common for a stock-heavy portfolio. Use 5% for a more conservative estimate.
Safe withdrawal rate — The percentage you'll withdraw annually from your portfolio. 4% is the classic rule. Use 3.5% for extra safety.
Real-world examples
$50K expenses, $20K part-time income
Gap: $30K/yr. At 4% SWR: Barista FIRE number = $750K vs full FIRE of $1.25M. That's $500K less to save. If you're saving $2,500/month, reaching $750K takes ~13 years vs ~20 years for full FIRE. Barista FIRE shaves 7 years off your timeline.
$60K expenses, $30K consulting income
Gap: $30K/yr. At 4% SWR: Barista FIRE number = $750K vs full FIRE of $1.5M. Part-time consulting in your field can pay $25–40/hour, and you already have the skills. This halves the savings target.
$40K expenses, $15K side business
Gap: $25K/yr. At 4% SWR: Barista FIRE number = $625K vs full FIRE of $1M. A small online business or freelance practice generating $1,250/month reduces your target by $375K. Many Barista FIRE seekers build this income stream before quitting their day job.
