FTE Calculator (Full-Time Equivalent)

Quick answer

The FTE calculator converts a mix of full-time and part-time employees into full-time equivalents (the number of full-time staff the hours add up to) and shows the total hours worked.

Full-time equivalents
23
Total hours per week
920
Part-time FTE
5
ACA full-time equivalents (30-hour basis)
25.22

FTE is used for budgeting, staffing ratios and legal thresholds. For example, U.S. employers with 50 or more full-time equivalents must offer health coverage under the Affordable Care Act (which counts 30 hours as full time).

  1. Full-time employees
  2. Hours per full-time employee per week

Field What to enter
Full-time employees A number
Hours per full-time employee per week A number
Part-time employees A number
Average hours per part-time employee per week A number
Hours in a full-time week A number

What each result means

  • Full-time equivalents = ([Full-time employees]×[Hours per full-time employee per week] + [Part-time employees]×[Average hours per part-time employee per week])÷[Hours in a full-time week]
  • Total hours per week = [Full-time employees]×[Hours per full-time employee per week] + [Part-time employees]×[Average hours per part-time employee per week]
  • Part-time FTE = [Part-time employees]×[Average hours per part-time employee per week]÷[Hours in a full-time week]
  • ACA full-time equivalents (30-hour basis) = [Full-time employees] + [Part-time employees]×[Average hours per part-time employee per week]×52÷12÷120
