How Much Part-Time Income Would Barista FIRE Require?

Required part-time income is the spending gap left after other income and the portfolio withdrawal you are willing to test—not a universal percentage of your old salary.

Short answer

Calculate the job's contribution after taxes, work expenses and healthcare changes.
Turn the annual gap into paid hours using realistic weeks and wages.
Always test the year that part-time income ends.

Choose a portfolio draw to test, not to certify

Assume a household needs $54,000 a year for living expenses and healthcare, excluding any incremental taxes already netted from income below. It has $600,000 invested. Suppose it wants to test a $15,000 net annual portfolio contribution—2.5% of the balance if the withdrawal is tax-free in this illustration—and has no other income.

The job must supply $39,000 after tax: $54,000 − $15,000. The 2.5% figure is an input chosen for analysis, not a safe-rate finding. If withdrawals come from pretax accounts, the gross draw needed to net $15,000 may be larger; access before 59½ is another separate question.

Convert the gap into a plausible work schedule

At $25 an hour and an illustrative 20% combined effective tax haircut, each paid hour contributes $20 before job expenses. Earning $39,000 net requires 1,950 paid hours a year, or 39 hours a week over 50 paid weeks. Calling that a part-time plan does not make the hours part-time.

If the desired schedule is 20 hours a week for 50 weeks, gross pay is $25,000 and illustrative take-home pay $20,000. The spending gap then requires $34,000 from the portfolio, or about 5.67% of $600,000 before any extra withdrawal taxes. The shortfall is visible before a long-range simulation is needed.

A wage offer is not a net-income estimate

Include commuting, licensing, equipment, unpaid time and any loss of benefits. A consulting rate is not comparable to an employee wage unless you account for business expenses, payroll taxes and paid leave. The 20% haircut above is only a transparent arithmetic assumption, not a tax calculation for either arrangement.

Healthcare can move both sides of the equation. A job with eligible coverage may lower premiums, while a role without benefits can leave Marketplace premiums and out-of-pocket costs in the household budget. Premium assistance depends on household income; adding earnings can affect it. Check actual plan eligibility rather than assuming a particular employer or occupation includes coverage.

Specify the bridge's last paycheck

If part-time work ends at 60 and Social Security starts at 67, seven years remain with neither source. At the example's unchanged $54,000 annual real spending and zero real return, that interval alone requires $378,000 before additional withdrawal taxes. This is a cash-demand illustration, not a recommendation to set aside that amount in cash.

Use the Barista FIRE calculator to test earnings and the transition to full retirement. Compare an earlier end to work, lower hourly pay and a year with no work. A plan that only works if the exact role remains available for decades deserves a larger margin.

Choose which variable you are willing to change

If the required hours are too high, compare a smaller spending budget, another period of full-time saving, a later full-retirement date or a different role. Keep these changes separate so you can see which actually closes the gap. Do not silently assume higher returns to compensate for an unwanted work schedule.

For stopping contributions without drawing down assets, use the Coast FIRE guide. For household context, view the sample demo before considering paid planning. These calculations are educational and cannot establish sustainable withdrawals or insurance eligibility for you.

A part-time label can hide full-time hours

Net annual job-income need: $39,000
Hourly wage / assumed tax haircut: $25 / 20%
Paid weeks: 50

39 paid hours per week

$39,000 ÷ ($25 × 0.80) ÷ 50 = 39. Work expenses would increase the requirement.
