Short answer
Part-time pay can reduce withdrawals, but it eventually stops. In the default example, the Barista path first cannot fund spending at age 78; staying full-time until 65 funds the selected horizon and ends with about $780,602 at age 90.

Barista path: first spending shortfall at age 78. Staying full-time: no shortfall within the horizon.
All amounts are in today’s dollars. Full retirement starts at 65; part-time wages stop then. Both paths stop work at that same age. End balances cannot erase an earlier shortfall.

A single smooth path, not a retirement recommendation. All amounts are today's dollars and stay constant in purchasing power. Ages mark the start of each year; the end age is exclusive.
This is an educational estimate, not tax or financial advice. Figures reflect the law year shown and the inputs you provide. Consult a qualified professional before acting.

How it’s calculated
- Until part-time starts, add the selected full-time savings at each year end. This savings figure is already net of living costs, healthcare and taxes.
- During part-time work, compare take-home wages with living costs plus part-time healthcare. Withdraw any deficit at year start; invest any surplus at year end.
- At the part-time end age, stop all wages and fund living costs plus retirement healthcare from the portfolio. Apply real growth after beginning-year withdrawals.
- Run a second path that continues the same full-time annual savings until the same full-retirement age. Record the first spending shortfall in each path, even if later surpluses replenish the balance.

- Part-time / retired healthcare
- $6,000 / $8,000 a year
- Return / inflation

Result
Barista path first falls short at age 78 and ends at $0. Staying full-time ends at about $780,602, with no shortfall within the horizon.
Five years of full-time saving are followed by 20 years drawing a $16,000 annual gap. This leaves about $567,379 at age 65 versus $1,444,533 with continued full-time saving. Each path then funds $48,000 a year for 25 years, at real growth of 1.05 ÷ 1.03.
What this calculator does not cover
- No income-tax calculation, Social Security, pensions, ACA subsidy, Medicare eligibility transition, account-access penalties or withdrawal ordering.
- Enter after-tax part-time income and net out-of-pocket healthcare. Coverage is not assumed to come with a part-time job.
- No changing spending phases beyond the healthcare change at full retirement, investment fees, market simulation or success probability.
- Full retirement can start immediately or after a part-time phase. A zero-length part-time phase compares identical work schedules.
Frequently asked
- How is Barista FIRE different from Coast FIRE?
- Coast FIRE assumes work pays the bills while investments grow without new deposits. This tool also allows a gap between part-time income and spending that must be drawn from investments.
- What happens when the part-time job ends?
- Part-time income becomes zero at the selected full-retirement age. Living costs and the retirement healthcare amount must then come entirely from the portfolio.
