Headcount versus full-time equivalent
Headcount counts people. Full-time equivalent counts capacity. A café with 4 full-timers and 16 casuals averaging six hours a week has a headcount of 20 and an FTE closer to 6.5.
Both numbers are correct and they answer different questions. Headcount matters for anything measured per person — licences, inductions, culture surveys, engagement. FTE matters for anything measured by capacity — labour budgets, productivity, staffing ratios.
Reporting only headcount in a casual-heavy business overstates the workforce, sometimes by a factor of three.
Where headcount is the right measure
Use headcount when the thing you are counting attaches to a person rather than to their hours:
- Licence and certification tracking — every individual needs their own
- Induction and policy acknowledgement completion
- Survey response rates
- Turnover, which is calculated against average headcount
- Per-employee software licensing, including most HR platforms
Counting it consistently
The awkward question in Australian businesses is casuals. A casual who has not worked a shift in four months is still technically employed. Counting them inflates headcount and depresses every per-head metric derived from it.
Pick a rule — commonly "worked at least one shift in the period" — write it down, and apply it every period. As with any HR metric, consistency matters more than which rule you choose.
Key takeaways
- Headcount counts people; FTE counts capacity
- In casual-heavy workforces headcount can overstate capacity several times over
- Use headcount for anything that attaches to a person, FTE for anything measured in hours
- Decide once how you count inactive casuals, and apply it consistently
RosterElf reports rostered hours alongside headcount, so you can see capacity rather than just how many names are on the list.
