How it is calculated

Hours available = number of employees × hours per employee. Hours deficit = hours required − hours available. Positive means hours are short; negative means there's a surplus.

Deficit in headcount = hours deficit ÷ hours per employee — how many additional (or excess) full-time positions are needed to close the gap.

A fractional headcount figure (e.g. 0.4) in practice usually means either part-time staffing, redistributing tasks among current employees, or bringing in a contractor for part of the volume — not always a full new hire.
