How Many Hours Is Considered Part Time in the US
Ever been told you’re “part-time” but work 32 hours a week? Or had your hours cut from 30 to 28 to avoid health insurance? The line between part-time and full-time is fuzzier than you might think.
There’s no federal legal definition of part-time in the FLSA. Part-time is whatever the employer says it is, with one big exception under the ACA.
The FLSA Stays Silent
The Fair Labor Standards Act regulates minimum wage, overtime, and recordkeeping, but it never defines “part-time” or “full-time.” For FLSA purposes, what matters is whether an employee is non-exempt (entitled to overtime over 40 hours) or exempt (passes the salary basis, level, and duties tests). The hourly cutoff is irrelevant to those rules.
Effective May 15, 2026, the federal exempt salary threshold is $684/week ($35,568/year). Anyone paid below that is non-exempt, regardless of how many hours they work.
BLS: Under 35 Hours
The Bureau of Labor Statistics uses 35 hours per week as its line. Anyone working fewer than 35 hours at all jobs is counted as part-time for survey and statistical purposes. BLS further splits part-time into “economic” (want full-time, can’t find it) and “non-economic” (choosing part-time) reasons.
BLS data shows roughly 27 to 30 million Americans work part-time in any given month. The non-economic group is consistently larger.
ACA: 30 Hours Means Full-Time
The Affordable Care Act’s employer mandate uses a stricter cutoff. An employee averaging 30 or more hours per week (or 130+ per month) is full-time for ACA purposes, and applicable large employers (50+ full-time-equivalent employees) must offer them health coverage or face penalties.
Those penalties are steep: roughly $2,000 to $3,000 per affected employee per year. This 30-hour line is why so many retail, food service, and gig schedules cap at 28 or 29 hours.
Actually, I’ve seen this play out with a friend who worked at a chain restaurant. She was scheduled for 30 hours a week for months, then suddenly her hours were cut to 28 because the company was worried about hitting the ACA threshold. It meant she lost out on health insurance and took a pay cut — all because of a 2-hour difference.
Typical Part-Time Ranges
In practice, part-time schedules cluster in two bands:
- 20-29 hours/week: retail, food service, gig work, kept under the ACA threshold
- 30-34 hours/week: skilled part-time roles, school staff, professional part-time, and reduced-schedule workers
A 25-hour-per-week worker at $18/hour earns $450/week, or $23,400 per year before taxes (25 x $18 x 52 = $23,400). The same worker at 30 hours/week earns $28,080 per year. The 5-hour gap is worth $4,680 per year.
Benefit Implications
Part-time status affects more than base pay:
- Health insurance: employer mandate kicks in at 30 hours/week
- Paid time off: most employer plans require 30 to 32 hours/week to accrue
- 401(k) eligibility: often 1,000 hours/year under ERISA safe harbor rules
- FMLA: requires 1,250 hours in the prior 12 months and 50 employees within 75 miles
A worker averaging 25 hours/week hits 1,300 hours per year, enough to clear the 1,000-hour 401(k) threshold but well short of the 1,250-hour FMLA mark.
Overtime Still Applies
Part-time doesn’t exempt anyone from FLSA overtime. A part-time worker who picks up extra shifts and crosses 40 hours in a workweek is owed 1.5x pay for hours over 40, same as full-time.
A 28-hour/week worker who covers a coworker and hits 48 hours gets 8 hours of overtime. At $18/hour that’s $216 in premium pay ($18 x 1.5 x 8) added to the regular $864 weekly check.
The 130-Hour ACA Month
For variable-hour employees, ACA status is measured look-back style over 3 to 12 months. An employee averaging 130 hours per month is full-time for the next “stability period.” The 130-hour monthly threshold equals about 30 hours per week (130 / 4.33 weeks).
FTE math uses 120 hours per month or 2,080 hours per year as one full-time equivalent. Two 20-hour-per-week workers count as one FTE.
Scheduling Around the Thresholds
Employers set schedules with these cutoffs in mind. A 29-hour cap avoids the ACA trigger. A 34-hour cap can still call itself “part-time” for PTO purposes while remaining close to full-time hours.
Does this mean you should always aim for 30 hours? Not necessarily — it depends on your priorities. If health insurance is important, 30 hours might be worth it. If flexibility matters more, 25 hours could be a better fit.
For workers, knowing the thresholds is leverage: 30 hours unlocks ACA coverage, 32 unlocks most PTO plans, and 40 unlocks overtime. Estimate pay at any part-time schedule with the Part-Time Salary Estimator and convert headcount to FTEs with the Full-Time Equivalent (FTE) Calculator.
