What is a Full-Time Equivalent (FTE)?

FTE is a standardized measurement equating part-time employee hours to full-time workers. For example, two employees working 20 hours per week equal 1.0 FTE in a 40-hour work week.

Why is the 50 FTE threshold important for US businesses?

Under the Affordable Care Act (ACA), businesses with 50 or more FTEs are classified as Applicable Large Employers (ALEs) and must offer affordable health insurance to full-time staff or face tax penalties.

How many hours per week count as 1.0 FTE?

For general workforce capacity planning, 40 hours per week (2,080 hours annually) is standard. For ACA regulatory compliance, 30 hours per week (120 hours per month) is the statutory threshold.

How do seasonal workers impact FTE counts?

Under IRS rules, seasonal workers employed for 120 days or fewer during the year are generally excluded when determining whether an employer meets the 50 FTE threshold.

Can an employee count as more than 1.0 FTE if they work overtime?

For HR capacity planning, overtime hours can push an individual above 1.0 FTE; however, for regulatory tax compliance (such as ACA), individual employees are capped at 1.0 FTE.

How does FTE simplify project budget planning?

FTE allows project managers to estimate labor effort by person-months or person-years rather than managing individual shift schedules.
