Coast FIRE vs Barista FIRE: Both Involve Part-Time Work — Which Fits?
Reference FIRE Number
$1.2M
Target Age
65
Monthly Needed
$800
Coast FIRE and Barista FIRE are often confused because both involve working part-time or in lower-income work after the traditional aggressive accumulation phase ends. The critical difference: Barista FIRE has a larger required portfolio (sufficient to fund a partial retirement with work supplementing), while Coast FIRE only requires the present value of the eventual FIRE number — a much smaller amount that grows entirely through compounding.
Barista FIRE: you accumulate enough portfolio to cover most retirement expenses (say, $900K for $36K/year at 4%) and supplement with part-time work ($15K–$20K/year). The portfolio alone isn't enough for full retirement, but combined with work income, total income is sufficient. This requires meaningful portfolio size — $600K–$900K for typical spending. Coast FIRE's threshold at age 35 for a $1.2M goal is only $185K — dramatically smaller.
The income requirement differs between the two strategies. Barista FIRE requires only $15K–$25K/year from work — flexible part-time employment. Coast FIRE requires enough income to cover full expenses ($48K/year for $4K/month spending) since the portfolio makes zero distributions during the coast period. Barista FIRE is easier on the income requirement; Coast FIRE requires more earned income but from a smaller starting portfolio.
Timeline to the "starting point" differs dramatically. Barista FIRE requires saving $600K–$900K before beginning — maybe 15–20 years from zero. Coast FIRE requires only $185K before beginning — potentially 5–8 years. This makes Coast FIRE accessible much earlier in a career. However, Barista FIRE's lower income requirement during semi-retirement may suit certain lifestyles better. The right choice depends on how long you can wait and how much income you need in the semi-retirement phase.
