ACA FullTime Equivalent (FTE) Calculator

The Affordable Care Act (ACA) requires applicable large employers (ALEs) to offer affordable health coverage to at least 95% of their fulltime employees and fulltime equivalents (FTEs). Determining whether you meet the employer shared responsibility provisions hinges on an accurate calculation of FTEs. This page explains the rules, shows how to compute FTEs, and provides an interactive calculator.

Why FTEs Matter

An ALE is defined as any employer with **50 or more fulltime employees** (including fulltime equivalents) on average during the calendar year. If you fall below that threshold you are not subject to the employershared responsibility penalties. Conversely, if you are at or above the threshold, you must offer affordable coverage that meets minimum value to your fulltime employees and their dependents.

Key Definitions

• Fulltime employee: An employee who works **30 hours or more per week** on average.
• Fulltime equivalent (FTE): A construct that converts parttime work into fulltime units. The ACA uses a twostep method:
  1. Count each fulltime employee (30+ hours/week) as 1 FTE.
  2. Group parttime employees (fewer than 30 hours/week) by total hours worked. Every **120 hours** of service by parttime employees equals 1 FTE.
• Applicable Large Employer (ALE): An employer with an average of 50+ FTEs during the measurement period.

How to Calculate FTEs

The calculation is performed on a **measurement year** (typically a calendar year). Follow these steps:

1. Identify each employees average weekly hours worked during the year.
2. Classify employees:
   • 30 hours or more fulltime employee (counts as 1 FTE).
   • Less than 30 hours parttime employee.
3. Sum the total hours worked by all parttime employees for the year, divide by 52 to get an average weekly total, then divide by 120 to convert to FTEs.
4. Add the number of fulltime employees to the parttime FTE total.
5. Divide the result by 12 (months) to obtain the **average monthly FTE count**. If that average is 50 or more, you are an ALE.

Example Calculation

Suppose a company has:

• 40 fulltime employees (30+hours/week each)
• 80 parttime employees who each work an average of 20hours per week.

Stepbystep:

1. Fulltime FTEs = 40
2. Total parttime weekly hours = 8020=1,600 hours
3. Parttime FTEs = 1,60012013.33
4. Total FTEs = 40+13.3353.33
5. Average monthly FTEs = 53.33124.44 (the employer would average about 4.44FTEs per month, which is far below the ALE threshold).

Interpretation of Results

The calculator displays three numbers:

• Total FTEs sum of fulltime employees and parttime equivalents.
• Average monthly FTEs total divided by 12.
• Employer status Applicable Large Employer if the average monthly FTEs are 50or higher; otherwise Not an ALE.

Common Pitfalls

• Seasonal workforce: Use the full years data; a temporary spike can push the average over the threshold.
• Multiple job titles: Count each individual employee only once, using their combined weekly hours across all roles.
• Volunteer hours: Hours performed by volunteers are not counted toward FTE calculations.
• Contractors: Independent contractors are outside the definition of employees for ACA purposes.

What to Do If You Are an ALE

1. Offer a health plan that is **affordable** (employee contributions do not exceed 9.12% of household income for 2024) and provides **minimum value** (covers at least 60% of total allowed costs).
2. Track employee enrollment each month to ensure at least 95% of fulltime employees and FTEs receive qualifying coverage.
3. File Forms 1094C and 1095C with the IRS and provide statements to employees.
4. Understand the two potential penalties:
   • Penalty for not offering coverage to at least 95% of fulltime employees.
   • Penalty for offering coverage that is not affordable or does not meet minimum value.
