How many hours is full time? 30, 35 and 40 hours explained

How many hours is full time? Ask three agencies and you get three answers. The U.S. Department of Labor says the Fair Labor Standards Act does not define full-time or part-time employment and leaves it to the employer. The IRS, enforcing the Affordable Care Act, treats 30 hours a week as full time. The Bureau of Labor Statistics counts 35 hours when it publishes employment figures. Meanwhile most job ads, handbooks and payroll systems still assume 40 hours and a 2,080-hour year. This guide sorts out which number applies to you, whether you are checking your own eligibility for benefits or writing the policy for your team.

How many hours is full time? Three answers

Each definition exists for a different reason, so none of them is wrong. The trick is knowing which one a given rule uses.

• Federal wage law: no number. The Department of Labor’s Wage and Hour Division states plainly that the FLSA does not define full-time or part-time employment, and that it is “a matter generally to be determined by the employer.” The FLSA cares about hours worked, minimum wage and overtime after 40, not labels.
• The Affordable Care Act: 30 hours a week or 130 a month. For the employer shared responsibility rules, the IRS defines a full-time employee as one with an average of at least 30 hours of service a week, or 130 hours in a calendar month. This is the only federal definition that creates an obligation, and it only binds employers with 50 or more full-time equivalent employees.
• Bureau of Labor Statistics: 35 hours. In its Current Population Survey, BLS classifies people who usually work 35 or more hours a week as full-time workers and everyone under 35 as part-time. BLS says the definition is for statistical purposes only. It does not give anyone rights, but it is why “35 hours” shows up so often in news coverage.
• Common employer practice: 40 hours. Five 8-hour days is the schedule most US employers mean by full time, and 40 × 52 = 2,080 hours a year is the standard payroll converts salaries with. Plenty of employers use 37.5, 35 or 32 instead, and that is legal.

If you only need one rule of thumb: an employer can draw its own full-time line anywhere, but once an employee averages 30 hours a week, a large employer owes them a health coverage offer under the ACA regardless of what the handbook calls them.

Is 32 hours full time? 35? 37.5? 40?

These are the full time hours per week people search for most, with how each standard treats them. The annual figures assume a 52-week year, and the monthly figure is the annual total divided by 12, which is how the IRS 130-hour threshold lines up with 30 hours a week.

Is 32 hours full time?

It depends on the employer. A 32-hour schedule, often four 8-hour days, is full time under the ACA because it clears 30 hours, so a large employer must treat that person as full time for health coverage. BLS would count the same person as part time. Whether 32 hours earns the full-time PTO rate, holiday pay or a 401(k) match depends entirely on the written policy. Bills proposing a 32-hour federal standard workweek have been introduced in Congress, but none has become law, so 40 remains the overtime line.

Is 37.5 hours full time?

Yes, under every standard. A 37.5-hour week is five 7.5-hour days: an 8:30 to 5:00 day with a 30-minute unpaid lunch. It is the most common “full time” schedule that is not 40, and payroll converts it with 1,950 hours a year instead of 2,080. The thing to watch is overtime. Hours 37.5 to 40 are paid at straight time under federal law, because overtime starts after 40 hours actually worked, unless the employer promises otherwise.

Is 35 hours full time?

Yes for the ACA and BLS, and yes at most employers that use a 35-hour schedule, which is common in offices, schools and nonprofits. At an employer whose policy says 40, a 35-hour employee may be classified as part time for PTO purposes while still being full time for health coverage. That gap is exactly why the policy has to be written down.

The sibling question, how many hours is part time, has the same answer from the other side: anything under the employer’s line, under 30 for the ACA, under 35 for BLS. And for the annual totals and how to convert a salary to an hourly rate, see how many work hours are in a year.

Full time vs part time: what full-time status usually changes

Full time vs part time matters because of what hangs on it. Almost none of it is required by federal law, which is why the policy is yours to write, with one big exception.

• Health coverage (the exception). If you have 50 or more full-time equivalent employees, the ACA requires you to offer affordable minimum-value coverage to employees averaging 30 or more hours a week, and their dependents, or risk an employer shared responsibility payment. Smaller employers have no federal mandate, though many offer coverage to full-time staff anyway.
• PTO accrual. No federal law requires vacation pay, so employers decide who earns it. A common policy gives full-time staff a fixed bank (for example 80 hours a year) and gives part-time staff a prorated amount, or accrues PTO per hour worked for everyone so the proration happens on its own. Our paid time off guide shows the accrual math. Note that most state and city paid sick leave laws cover part-time employees too, so sick time usually cannot be limited to full-timers.
• Paid holidays and other benefits. Holiday pay, retirement plan matches, life and disability insurance, and tuition help are typically full-time benefits by policy. Retirement plans have their own hours-based eligibility rules under federal law, so check plan documents before excluding part-timers.
• Scheduling guarantees. Some employers promise full-time staff a minimum number of weekly hours. That promise lives in the handbook and offer letter, and a few cities with predictive scheduling laws add rules about offering extra hours to existing part-time staff before hiring.

What full-time status does not change: FMLA. Eligibility for federal family and medical leave has nothing to do with the full-time label. The Department of Labor’s test is 12 months with the employer, 1,250 hours actually worked in the 12 months before leave starts, and a worksite with 50 or more employees within 75 miles. That 1,250 hours is about 24 hours a week, so a regular part-time employee can qualify and a full-time new hire with eight months of service cannot. Our FMLA leave guide covers the rules for employers in detail.

Full-time status vs exempt status: two different questions

The most expensive confusion in this area is treating “full time” and “exempt” as the same thing. They answer different questions.

• Full time or part time describes how many hours someone is scheduled. The employer defines it.
• Exempt or non-exempt describes whether the FLSA minimum wage and overtime rules apply to the job. Federal law defines it with a salary basis test, a salary level test and a duties test. Under the Department of Labor’s current rule, the salary level for the executive, administrative and professional exemptions is $684 a week ($35,568 a year), and several states set higher thresholds. Read exempt vs non-exempt for the tests and the state figures.

All four combinations exist. A full-time barista is non-exempt. A part-time bookkeeper paid hourly is non-exempt. A full-time general manager on a qualifying salary with management duties is exempt. A part-time salaried professional can be exempt too, as long as the full weekly salary threshold is paid regardless of the reduced schedule.

Overtime kicks in after 40 hours worked no matter what the schedule is called. A non-exempt employee on a 37.5-hour “full-time” schedule who works 44 hours earns 4 hours of time and a half, not 6.5. A part-time employee who picks up extra shifts and hits 43 hours earns 3 hours of overtime that week even though the handbook calls them part time. Only hours actually worked count: PTO, holidays and sick time do not push anyone over 40 under federal law. The step-by-step math, including the regular rate when bonuses or two pay rates are involved, is in how to calculate overtime, or run the numbers in the overtime calculator.

The ACA 30-hour rule and the look-back measurement method

If your business is at or near 50 full-time equivalent employees, the ACA definition is the one that can cost you money, so it is worth knowing how the IRS measures it.

Hours of service, not just hours worked. The IRS counts every hour an employee is paid or entitled to pay for working, plus paid time when no work is done: vacation, holidays, illness, disability, layoff, jury duty, military duty and leaves of absence. So a 28-hour-a-week employee who takes a paid vacation week still accrues hours of service that week. This is the opposite of the FLSA overtime rule and the FMLA 1,250-hour rule, which count only hours actually worked.

Two ways to measure. The IRS allows either method:

1. Monthly measurement method. Check each calendar month: 130 or more hours of service makes the employee full time for that month. Simple, but an employee can flip between full time and part time from month to month, which makes coverage offers messy.
2. Look-back measurement method. Measure hours over a past “measurement period” and lock the result in for a following “stability period.” Under the regulations (26 CFR 54.4980H-3), the standard measurement period runs between 3 and 12 months, an optional administrative period of up to 90 days can sit between the two, and the stability period must be at least six consecutive calendar months and no shorter than the measurement period for employees who measured as full time. Most employers with variable-hour staff use a 12-month measurement period and a 12-month stability period. Someone who averaged 30 hours over last year’s measurement period is treated as full time for all of this year’s stability period, even if their hours drop.

The look-back method can only be used to decide who must be offered coverage. The IRS does not allow it for the separate question of whether you are an applicable large employer in the first place; that count uses actual monthly hours. Check the IRS employer shared responsibility pages for the current rules before you rely on either method.

Full-time equivalents (FTE): the formula and an example

A full-time equivalent turns part-time hours into whole full-time positions. Two formulas are in common use, and they give different answers, so always say which one you mean.

Budgeting and staffing FTE (40-hour basis): FTE = total weekly hours ÷ 40. Over a year the same thing is total annual hours ÷ 2,080, which is also how the IRS counts FTEs for the small business health care tax credit (hours above 2,080 for one person are not counted).

ACA applicable large employer FTE (30-hour basis): for each month, add the hours of service of all employees who were not full time that month, counting no more than 120 hours for any one person, and divide by 120. Add the result to the number of full-time employees, do that for each month of the prior year, then divide by 12. If the average is 50 or more, you are an ALE. The IRS says a fraction is rounded down to the next lowest whole number.

Here is an illustrative example. Suppose Northfield Coffee in Austin, Texas grows to 14 people: 6 full-time employees scheduled 40 hours a week each, and 8 part-time employees scheduled 24, 24, 20, 20, 16, 16, 12 and 12 hours a week.

On a staffing basis the shop runs 9.6 FTEs, which is the number to use for labor budgets and for comparing locations. On the ACA basis it is 11.2, because the IRS divisor assumes a 30-hour full-time week. Either way Northfield is far below 50 and has no coverage mandate. A business with 35 full-timers and 30 part-timers, on the other hand, should run the ACA math every month, because the part-time hours alone can carry it over the line.

A couple of details trip people up. Owners who draw a salary count as employees for FTE purposes in some tests and not others, and seasonal workers have their own exception for ALE status, so read the IRS instructions for the test you are applying. And an FTE count says nothing about any individual’s rights: two 20-hour employees equal one FTE for a budget, but neither of them is a full-time employee for coverage.

Writing the full-time policy for your handbook

Since the FLSA leaves the definition to you, the handbook is where full-time status is actually created. A good policy answers four questions: what the hours line is, whether it is measured on scheduled or actual hours, how long someone has to average over or under the line before their status changes, and what the status affects. The wording below fits section 3 of our employee handbook templates. Fill in the brackets, delete the options you do not use and have counsel review it with the rest of the handbook.

Three things to get right before you paste this in. First, make sure the hours line matches what payroll and your benefits carrier use; a handbook that says 32 while the carrier enrolls at 30 creates employees who are owed coverage nobody offered. Second, if you give part-time staff a lower PTO rate, confirm your state does not treat the difference as a problem for legally required sick leave. Third, the FMLA, overtime and ACA rules override the handbook wherever they are more generous, so never write a policy that promises less than the law. Our guide to the attendance policy and the hybrid work schedule cover the related sections, and a PTO tracker that accrues per hour worked removes most of the proration arguments on its own.
