Coast FIRE vs Barista FIRE Comparison Calculator 2027
Compare Coast FIRE (stop saving, let compound) vs Barista FIRE (part-time work + portfolio) — see which lets you quit earlier in 2027.
Coast FIRE Math
Save aggressively until portfolio = future retirement need / (1+r)^years. After that, your contributions stop helping much — compound growth alone reaches the goal. You still work for living expenses but no retirement savings needed.
Barista FIRE Math
Quit corporate job, take low-stress part-time work (think barista, librarian, ski instructor). Part-time income covers some living costs. Portfolio covers the rest. Smaller portfolio needed because barista income reduces withdrawal need.
Coast vs Barista Tradeoff
Coast = keep full income, less stress about saving, lifestyle inflation tempting. Barista = lower income but free time and lifestyle change immediately. Pick based on: do you hate current job? (Barista) Or just hate saving? (Coast).
Healthcare Bridge
Both paths face healthcare gap until Medicare (65). Barista jobs sometimes include benefits (Starbucks, REI). Coast keeps employer health insurance. Otherwise budget $800-1,500/mo for ACA + dental.

Frequently Asked Questions
What return rate should I use?
7% real (after inflation) for diversified stock-heavy portfolio. 5% for 60/40. 3% for retiree bond-heavy. Trinity Study used 7% nominal which is 4% real after inflation.
What if I hit Coast and market crashes?
You'd need to resume saving to recover. Or push retirement age out 2-3 years. Why most Coast FIRE folks keep contributing 'just in case' even past coast number.
Can I do both — Coast then Barista?
Yes. Hit Coast FIRE at 40, work full-time 5 more years just for healthcare, then drop to barista at 45 while portfolio compounds in background. Hybrid is common.
