Occupancy vs utilization: the difference, with numbers
Both divide the time spent handling contacts by a base. The base is what changes: occupancy uses the time agents were logged in and available, utilization uses every paid hour, including training, meetings, coaching and breaks.
| Occupancy | Utilization | |
|---|---|---|
| Formula | Handle time ÷ available time × 100 | Handle time ÷ paid time × 100 |
| Example (108 h handling, 136 h available, 160 h paid) | 79% | 68% |
| Usual target | 75–85% | 60–70% |
| Answers | How busy are agents while on the queue? | How much of the paid shift goes to customer work? |
| Risk when too high | Burnout, errors, longer handle time | No time left for training and coaching |

Put the inputs in column B from row 2, then paste the formulas below. They work the same in Excel and Google Sheets.
| Cell | What | Value or formula | Example |
|---|---|---|---|
| B2 | Handle time (hours) | 1020 | 1020 |
| B3 | Available, logged-in time (hours) | 1200 | 1200 |
| B4 | Agents | 10 | 10 |
| B6 | Occupancy (%) | =ROUND(B2/B3*100,1) | 85 |
| B7 | Idle hours per agent | =ROUND((B3-B2)/B4,1) | 18 |

Frequently asked questions
- How do you calculate occupancy?
- Divide the time agents spent handling contacts (talk, hold and wrap-up) by the time they were logged in and available. 1,020 handle hours out of 1,200 available hours is 85% occupancy.
- What is a good occupancy rate?
- 75–85% is the usual target for voice and chat. Above 90% for long periods leads to burnout and errors; below 70% means you are overstaffed for the volume.
- What is the difference between occupancy and utilization?
- Occupancy uses logged-in available time as the base; utilization uses all paid time, including training, meetings and breaks. Utilization is therefore always lower. An agent paid 160 hours, available 136 hours and handling contacts 108 hours has 79% occupancy (108 ÷ 136) but 68% utilization (108 ÷ 160).
