Definition
Occupancy is total handle time divided by total staffed (available) time. If an agent is available for 60 minutes and spends 51 handling contacts, occupancy is 85%; the remaining nine minutes are idle time spent waiting for the next contact.
Staffed time excludes breaks, meetings, training and absence, those belong in shrinkage. Putting them in the occupancy denominator makes the number look much lower than agents actually experience.
Crucially, occupancy is an outcome rather than a lever. It is set by the relationship between arriving workload and scheduled agents, which is exactly what queueing theory models. Small teams mathematically run at lower occupancy because one agent cannot be half busy.
Why it matters
- The healthy planning band is 85–92%. Above 95% agents move straight from one contact to the next all day, and quality, absence and attrition all deteriorate.
- Target occupancy sits in the denominator of capacity planning, so it directly affects how many FTE you fund.
- Occupancy that is too low is expensive; occupancy that is too high is a hidden liability that shows up months later as attrition cost.
