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.
