How many hours is part-time?
The Fair Labor Standards Act does not define part-time or full-time. That call is left to employers, the IRS, and the Bureau of Labor Statistics, and each draws the line in a slightly different place.
The BLS counts anyone working 1 to 34 hours per week as part-time in its Current Population Survey. Most U.S. employers settle on a narrower range, usually 20 to 29 hours per week, often to stay under the ACA full-time threshold.
Typical part-time schedules run from 10 hours per week (a side gig) up to 30 hours per week (a near-full schedule). This calculator lets you model any number of hours, including fractional values like 22.5 or 27.75.
ACA 30-hour rule and benefits eligibility
The Affordable Care Act takes a different view than the BLS. Under the IRS Employer Shared Responsibility rules, an employee who averages 30 or more hours per week, or 130 or more hours per calendar month, counts as full-time for health-coverage purposes.
That creates a gray zone for workers at 30 to 34 hours per week. The BLS still calls the schedule part-time, but Applicable Large Employers may owe health coverage. The calculator flags this band with a callout so you know which classification applies to your situation.
Applicable Large Employers (50 or more full-time equivalents) also calculate FTE on a monthly basis, dividing total monthly part-time hours by 120 and capping at 120 per employee. The calculator's FTE output uses a weekly baseline (default 40 hours), which is the convention most HR teams use for headcount planning.
Converting part-time hours to weekly, monthly, and annual pay
The math is simple. Weekly pay equals hours per week times hourly rate. Annual pay equals weekly pay times weeks worked per year. Monthly pay equals weekly pay times (weeks per year divided by 12), which falls back to about 4.333 weeks per month when you work a full 52 weeks.
Worked example: 22 hours per week at $20 per hour for 50 weeks per year equals $440 per week, $880 biweekly, $1,833.33 per month, and $22,000 per year.
If you take unpaid weeks off, drop the weeks-per-year input below 52 so the monthly and annual figures reflect actual paid time. The calculator's quick-pick chips cover the most common cases (50, 48, 40, and 26 weeks per year).
Part-time hours vs. full-time: pay, benefits, and overtime
A 25 hour per week schedule at $20 per hour runs about $26,000 per year. The same hourly rate at 40 hours per week runs about $41,600 per year, a $15,600 gap before any benefits are factored in. The calculator shows this gap in the "Pay vs. full-time" row.
FLSA overtime still applies to part-time employees once weekly hours pass 40, since the rule is hours-based, not status-based. When your weekly hours exceed 40, the calculator surfaces an overtime multiplier (default 1.5x) and splits regular and overtime pay.

Frequently Asked Questions
Common questions about part-time hours calculator
What is considered part-time hours?
Most employers and the U.S. Bureau of Labor Statistics treat anything under 35 hours per week as part-time. The Affordable Care Act uses a different line, 30 hours per week, as the threshold that triggers full-time employer health-coverage obligations.
How many hours is part-time per week?
Part-time work usually falls between 15 and 30 hours per week, though the FLSA itself does not define part-time. The BLS draws the line at 1 to 34 hours per week.
What is the ACA 30-hour rule?
Under the Affordable Care Act, an employee who averages 30 or more hours per week, or 130 or more hours per month, counts as full-time for the employer shared-responsibility (health insurance) mandate, regardless of internal job title.
Do part-time workers get overtime pay?
Yes. The FLSA overtime rule is hours-based, not status-based. Any non-exempt employee (part-time or full-time) who logs hours past 40 in a workweek is owed overtime at 1.5 times their regular rate. See our overtime calculator for the math.
How do I calculate annual income from part-time hours?
Multiply hours per week by hourly rate, then multiply by weeks worked per year. For example, 25 hours times $18 times 50 weeks equals $22,500. Subtract any weeks you are not paid to keep the number realistic.
Do part-time workers get benefits?
It depends on the employer and applicable law. The ACA may require health coverage at 30 or more hours per week, and some states mandate sick leave or retirement enrollment for part-timers. PTO and 401(k) eligibility are usually set by employer policy.
Is 32 hours considered part-time or full-time?
It sits in a gray zone. The BLS calls 32 hours part-time (under 35), but the ACA considers it full-time for health-coverage purposes (over 30). Many employers cap part-time schedules at 29 hours per week specifically to stay under the ACA threshold.
How many hours a year does a part-time worker work?
A 25 hour per week worker on a year-round schedule logs about 1,300 hours per year, versus roughly 2,080 hours for a typical 40 hour per week full-time worker. Use the annual work hours calculator to model any schedule.
