How It Works
Our FTE Calculator accurately converts employee hours into Full-Time Equivalents, a critical metric for businesses to understand their workforce size. This is particularly vital for determining Applicable Large Employer (ALE) status under the Affordable Care Act (ACA), where exceeding 50 FTEs in 2026 triggers specific health insurance coverage mandates and potential penalties. Understanding your FTE count prevents costly compliance errors and helps with strategic staffing decisions.
The core FTE calculation involves summing all hours worked by full-time employees and then converting all hours worked by part-time employees into full-time equivalents. Specifically, for each part-time employee, their total hours worked in a month are divided by 120 (the ACA-defined threshold of hours for a full-time employee in a month). These individual part-time FTEs are then summed and added to the count of full-time employees to arrive at the total FTE count.
A common mistake is only counting full-time employees and neglecting the significant impact of part-time hours on FTE calculations. Remember that seasonal employees can also contribute to your FTE count during their employment period, potentially pushing you over the ALE threshold. Always use a consistent measurement period (e.g., 12 consecutive months) for ACA compliance to avoid misrepresenting your FTE count.
Example: Q1 2026 FTE Calculation for a Small Business
- 1 Input: For Q1 2026, a business has 35 full-time employees (each working 160 hours/month). Additionally, there are 20 part-time employees who each worked an average of 80 hours/month during Q1 2026.
- 2 Calculation: Full-time employees = 35 FTEs. Part-time employee hours = 20 employees * 80 hours/month = 1600 hours/month. Part-time FTEs = 1600 hours/month / 120 hours/month (ACA full-time threshold) = 13.33 FTEs.
- 3 Intermediate Result: Total FTEs = 35 (full-time) + 13.33 (part-time) = 48.33 FTEs.
- 4 Final Result: The business has 48.33 FTEs for Q1 2026. Based on this, the business is not an Applicable Large Employer for 2026, as its FTE count is below the 50-FTE threshold, and therefore, it avoids ACA employer mandate penalties for this period.
