Headcount is the number of people employed at a point in time. It sounds simple, but which people you count, and when, changes which laws apply to you.
A team of 10 full-time employees and a team of 20 half-time employees have different headcounts (10 vs. 20) but the same FTE (10). Headcount matters for anything per person: equipment, uniforms, onboarding, software seats and management span. FTE matters for anything per hour: labor cost, coverage and productivity. See FTE and the FTE calculator.

| Law | Threshold | How it counts |
|---|---|---|
| Title VII | 15 or more employees | For each working day in 20 or more calendar weeks in the current or preceding year |
| COBRA | At least 20 employees | On more than 50% of typical business days in the previous calendar year |
| FMLA (employer coverage) | 50 or more employees | In 20 or more workweeks in the current or previous calendar year |
| ACA employer rules | At least 50 full-time employees, including full-time equivalents | Average over the prior year; full-time means 30 hours a week or 130 hours a month |
| WARN Act | 100 or more employees | Excluding part-time employees (with a second test based on total hours) |
Notice that the ACA uses full-time equivalents, WARN leaves out part-timers, and the others count people over weeks or days. A headcount on one day does not answer any of these on its own. Many states also have their own thresholds, often lower.
A restaurant has 46 people on payroll: 30 who average 34 hours a week and 16 who average 20 hours a week. Headcount is 46, below 50. Under the IRS rules for applicable large employers, the 30 are full-time (30 or more hours a week). The 16 part-timers work about 20 times 52 divided by 12, or roughly 87 hours a month each, about 1,387 hours a month in total. Dividing by 120 gives about 11.6 full-time equivalents.
So the restaurant has about 30 + 11.6 = 41.6 full-time employees for ACA purposes if this held all year: still under 50. But if it adds 9 more 30-hour employees for the summer, the average for the year could cross the line. Monthly hours from time records are the input that answers the question; a headcount on one day is not.
One headcount number rarely answers a question by itself. Report it with the details that explain it: full-time and part-time, by location, new hires and leavers in the period, and total hours. Then a change in headcount can be read correctly, such as more people working fewer hours each.
| Measure | This month | Last month |
|---|---|---|
| Headcount at month end | 64 | 60 |
| Full-time / part-time | 38 / 26 | 38 / 22 |
| New hires / leavers | 7 / 3 | 4 / 5 |
| Total hours worked | 7,420 | 7,380 |
The table is from a garden center in spring. Headcount rose from 60 to 64, which looked like growth, but total hours barely moved.
The four extra people are all part-time seasonal staff covering weekends, while some full-time staff work fewer overtime hours. The owner sees that the labor budget is unchanged, but onboarding, uniforms and scheduling work went up with headcount, and plans for that in the next spring. She also adds a line to the report for average hours per person, which fell from 123 to 116, so the next change is easy to read.
The number of individual employees on payroll at a point in time, each counted once regardless of hours worked.
Headcount counts people. FTE counts hours converted into full-time units. Two part-time employees can be 2 in headcount and 1 in FTE.
Yes, each person counts once. Whether they count for a specific law depends on that law’s method. WARN excludes part-time employees, while the ACA converts their hours into equivalents.
Add the headcount at the start and end of a period and divide by two, or average the headcount for each month. Use the same method every time.
Not usually. Headcount counts employees on payroll. Some companies report contractors separately so the full workforce is visible.
For internal reporting, many companies list them separately. Whether they count for a specific law depends on that law’s rules.
