How to Calculate FTE

What is FTE?

Full-Time Equivalent (FTE) standardises headcount by expressing part-time workers as fractions of full-time. Essential for budgeting, ACA compliance (US ≥ 50 FTE triggers mandate), and workforce planning.

Formula

FTE = (Hours worked / Standard full-time hours) | e.g., 20 hours/week ÷ 40 hrs/week = 0.5 FTE

Worked Examples
