How the headcount calculator works

Ending headcount:
The calculator starts with beginning headcount, adds new hires and transfers in, then subtracts separations and transfers out.

Average headcount:
Average headcount is calculated by adding starting headcount and ending headcount, then dividing by two.

FTE headcount:
Full-time employees are added to part-time FTE, where part-time FTE is based on average weekly hours divided by full-time weekly hours.

Workforce cost:
The calculator estimates salary cost, loaded payroll cost, monthly cost, and cost per employee.
