Determining Group Size
Michigan law stipulates that group size includes both full-time employees and full-time equivalent employees, also known as FTEs. It is determined each calendar year and generally depends on the average size of an employer's workforce during the prior year.
Group definitions
Small group
A group with 50 or less full-time employees, made up of both full-time employees and FTEs. Groups must consider all related entities, company divisions and locations to determine group size.
Large group
A group with 51 or more full-time employees, made up of full-time employees and FTEs.
Employee types
- Full-time employee: Someone employed on average at least 30 service hours per week – or at least 130 hours per month.
- Full-time equivalent employees: A calculated combination of all non-full-time employees, determined by an equation, as outlined below.
How to calculate the number of FTEs
Add the number of hours of all non-full-time employees for the month but do not include more than 120 hours per employee. Divide the total number of those hours by 120. This is your number of FTEs.
How to calculate the total number of eligible employees
Add the number of FTEs to the total number of existing full-time employees. This is how many eligible employees you have.

Example:
- ABC company has 30 full-time employees (employed 30 or more hours per week on average).
- ABC also has 20 part-time employees who each work an average of 15 hours per week.
- 20 employees × by 15 hours per week × by four weeks = 1,200. This is the total monthly hours worked by part-time
employees. - 1,200 hours ÷ by 120 = 10 FTEs.
- 30 full-time employees + 10 FTEs = 40 total eligible employees.
If the size of your employer group changes, it could result changes to:
- Government reporting requirements
- Health coverage requirements
- Potential tax credits
- Rating methods
- The types of plans available for purchase
