Full time has no single legal number. Federal wage law leaves it to each employer. The IRS counts 30 hours a week as full time for its health coverage rules, the Bureau of Labor Statistics counts 35 or more, and overtime starts after 40. Whatever number you pick for your own team, XShift AI’s Autopilot holds each person’s scheduled week to it, for one named person or everyone.
Full-time hours per week: why you get seven different answers
Full time is not one number because it is not one rule. Each government office that uses the term picked a line for its own job. Federal wage law never picked one at all.
So the useful question is not how many hours is full time. It is full time for what. Here is where each line sits on a normal week.
That is why one person can be full time and part time in the same week. For example, if you have an employee who works 32 hours every week, the IRS health coverage rules count them as full time, because 32 is over 30. The Bureau of Labor Statistics counts them as part time, because 32 is under 35. And they never reach overtime, because 32 is under 40.
Same person, same week, three answers. Mix them up and you can tell somebody they are part time while a government rule counts them as full time.
The 7 answers to how many hours is full time
Here is every answer, who uses it, and what it actually decides.
Answer 1
Federal wage law
No number
The Fair Labor Standards Act does not define full-time or part-time work. The Department of Labor leaves it to the employer.
Source: US Department of LaborAnswer 2
ACA full-time employee definition
30 hours a week
Or 130 hours a month, on average. The IRS uses this line to decide who counts as full time under its health coverage rules.
Source: IRSAnswer 3
Government job figures
35 hours or more
So is 35 hours full time? In government job figures, yes. The Bureau of Labor Statistics counts anyone who usually works 35 hours or more as full time, and says this is for its surveys, not a legal definition.

Overtime
Over 40 hours
This is a pay rule, not a definition of full time. Covered employees earn time and a half for every hour over 40 in a workweek.

Federal government jobs
40 hours a week
The traditional federal workweek is 40 hours. Federal part-time jobs run from 16 to 32 hours a week.

Full-time equivalent
120 hours a month
When the IRS adds part-time hours together, every 120 hours a month is one full-time person. Over a year, 40 hours for 52 weeks is 2,080 hours.

Your company
Your number
Your handbook, your offer letters and your benefits plan decide what full time means inside your business. Even the government’s own survey of employer pay uses each employer’s definition instead of an hour count.

- No federal law sets one number for full time.
- Thirty hours is the IRS line for health coverage rules.
- Thirty-five hours is how the government counts full-time workers in its job numbers.
- Forty hours is where overtime starts.
- Everything else is your call, so write your number down.
Full time vs part time hours: which number answers your question?
Choose the number by the question you are asking, not by the one you heard last. Find your question on the left. The number that answers it is on the right.
Does this person count as full time for health coverage rules?
30 hours a week on average

When do I start paying time and a half?
After 40 hours in a workweek

How does the government count full-time workers in its job numbers?
35 hours or more

How many full-time people do my part-time hours add up to?
120 hours a month each
IRS
What does full time mean on my job posting or in my handbook?
Whatever number you choose
You
If your question is not on the list, the answer is usually the last row. Your state can also add its own rules on top of these, so check with your state labor department before you change how you classify anyone.
How many hours is part time?
Part time is anything below the full-time line of the rule you are using. So when the rule moves, part time moves with it.
What counts as part time, hours per week
Look at where the white mark lands. For example, the employee on 32 hours sits inside the BLS bar and inside the federal jobs bar, so both of those call them part time. It sits outside the IRS bar, so the health coverage rules do not.
So when somebody asks whether a job is part time, ask one thing back. Part time for what?
How to calculate full-time equivalent employees
A full-time equivalent, or FTE, turns part-time hours into a count of full-time people. The FTE calculation the IRS uses for its health coverage count takes three steps.
- 1
Add up the hours
Add up the hours worked in the month by every employee who is not full time.
- 2
Cap each person at 120
Count no more than 120 hours for any one person.
- 3
Divide by 120
Divide the total by 120. The answer is your number of full-time equivalents for that month.
For example, the IRS uses an employer with 20 part-time employees who each work 60 hours a month.
20 people × 60 hours
1,200 hours
1,200 ÷ 120
10
The answer
10 full-time equivalents
Twenty part-time people count as ten full-time ones. The IRS then adds those ten to the employer’s full-time employees for its count (IRS).
Before you rely on it: this count can decide real tax questions for your business. Run your own numbers past your accountant or benefits adviser.
How to keep each person at the weekly hours you set
Once you know your number, the job is keeping every week at it. That takes three habits, and you can do all three with a spreadsheet.
First, write the number down for each person. Put the weekly hours you agreed in the offer letter and in your own notes. Second, add up every person’s week before you post it. One total per row, every single week. Third, recount whenever a shift changes. An extra shift, a covered call-off, or a repeating shift all change the total.
The third habit is the one that breaks. A spreadsheet only adds the hours when somebody remembers to add them. That Friday call-off you covered in a hurry is how a 32-hour week turns into 40, and you find out when payroll runs.
XShift AI’s Autopilot does that recount for you, on every shift, before the shift is saved. You write the limit the way you would say it out loud.
What you type into Autopilot
For one person
“[Employee name] can’t work more than 32 hours a week.”
For the whole team
“Nobody works more than 38 hours a week.”
What happens to every shift after that
- 1
It finds every shift already on that person’s schedule for the week.
- 2
It adds up those hours.
- 3
It adds the hours of the shift somebody is trying to give them.
- 4
It compares the new total with your limit.
- 5
If the total would go over, it turns the shift away and shows the hours behind it: where the person is now, where this shift would take them, and how far past your limit that is.
You choose whether going over stops the shift outright or lets a manager push it through. When XShift AI is building your week, filling open shifts or covering a call-off, the person is simply skipped and it moves on to somebody who fits.
If you also want nobody going past 40, say that too. Autopilot will turn away any shift that would take somebody into overtime. Book a demo and watch it turn a shift away live.
The same week, two ways
By hand, in a spreadsheet
With XShift AI Autopilot
Adding up the week
You add each person’s hours only when you remember to.
Every shift is added to that person’s week before it saves.
Building next week
You type names into a grid and total the rows at the end.
XShift AI builds the week and skips anyone a shift would push past their limit.
A call-off on Friday
You give it to whoever answers, and nobody recounts their week.
The person covering is checked against their limit before they get the shift.
A repeating shift
It copies forward every week, and so does any mistake in it.
Each copy is checked against the week it lands in.
When you find out
On payroll, after the hours are already paid.
On the screen, while the shift is being saved, with the numbers.
What you get back
You post next week’s schedule, and every person is already at or under the hours you agreed with them. Nobody added up a column. Nobody found a surprise on payroll.
Zero columns
No more adding up hours by hand before you post.
Friday is safe
A covered call-off cannot quietly push somebody past their limit.
Nobody past 40
Nobody goes into overtime unless you allow it.
One sentence
One sentence covers one person. One more covers the whole team.

Frequently asked questions
How many hours is full time?
There is no single legal number. Federal wage law does not define full time, so each employer decides what it means in their own business. Government rules that do use a number use different ones: the IRS counts 30 hours a week on average as full time for its health coverage rules, the Bureau of Labor Statistics counts 35 hours or more in its job figures, and federal overtime starts after 40 hours in a workweek.
Is 30 hours a week full time?
For the IRS health coverage rules, yes. The IRS counts an employee who works on average at least 30 hours a week, or 130 hours a month, as full time under the Affordable Care Act. For the Bureau of Labor Statistics, no, because it counts full time as 35 hours or more. Inside your own business, it is full time if your policy says it is.
Is 32 hours a week full time?
It depends on which rule you are asking about. The IRS health coverage rules count 32 hours as full time, because it is over 30. The Bureau of Labor Statistics counts it as part time, because it is under 35. A federal government job at 32 hours is part time, because federal part-time jobs run from 16 to 32 hours a week.
Is 40 hours a week full time?
Yes, under every rule on this page that uses a number. Forty hours is over the IRS line of 30 and the BLS line of 35, and it is the traditional full-time week for federal government jobs. It is also the overtime line: covered employees earn time and a half for every hour over 40 in a workweek.
How many hours is part time?
Part time is anything under the full-time line of the rule you are using, so there is no single number. The Bureau of Labor Statistics counts fewer than 35 hours a week as part time. The IRS health coverage rules treat anyone averaging under 30 hours a week as not full time. Federal government part-time jobs run from 16 to 32 hours a week, and federal wage law does not define part time at all.
How many hours a year is full time?
A 40-hour week worked for 52 weeks is 2,080 hours a year. The IRS uses 2,080 hours as one full-time equivalent employee when it works out who qualifies for its health care tax credit for smaller employers. Paid time off and holidays are part of how those hours are counted, so check the form instructions for the exact rules.
How do I calculate full-time equivalent employees?
For the IRS health coverage count, add up the hours worked in the month by everyone who is not full time, count no more than 120 hours for any one person, and divide the total by 120. For example, 20 part-time employees working 60 hours a month each is 1,200 hours, and 1,200 divided by 120 is 10 full-time equivalents. That count can decide real tax questions, so check your own numbers with your accountant or benefits adviser.
When does overtime start, and is it the same as full time?
Federal overtime starts after 40 hours in a workweek, and it is not the same thing as full time. Full time is a label an employer or a government rule gives a job. Overtime is a pay rule: covered employees earn at least time and a half for every hour over 40, whether their job is called full time or part time.
What scheduling software keeps staff under a weekly hour limit I set?
XShift AI does. You type the limit into Autopilot in plain English, for one named person or your whole team, and every shift is checked against it before it saves. It finds the shifts already on that person’s schedule for the week, adds up their hours, adds the hours of the new shift, and compares the total with your limit. If the total would go over, the shift is turned away and the numbers are shown, or a manager can push it through if you allow that. The check runs when XShift AI builds your week, fills open shifts, covers a call-off, lays down a repeating shift, and when a manager adds a shift by hand.
Can I set my own full-time hours for my company?
Yes, federal wage law leaves the definition of full time to the employer. Once you pick your number, use XShift AI’s Autopilot to set it as a weekly hour limit for one named person or your whole team, and it turns away any shift that would go past it. Keep in mind that the IRS health coverage rules and federal overtime still use their own numbers, whatever your handbook says.
