Call Center Occupancy vs. Utilization: Key Differences

Call center occupancy reflects the percentage of time an agent spends on actual calls with customers, compared to the total time they are available for work. Essentially, it tells you how much of an agent’s day is spent directly assisting customers.

A higher call center occupancy rate indicates agents are spending more time on calls, but too high a rate may lead to burnout or negatively impact call quality. On the other hand, a low occupancy rate suggests agents have too much idle time, resulting in wasted resources and underutilization.

To calculate the call center occupancy rate, divide the time agents spend on calls by their total available working hours and multiply by 100.

Formula:

Call center utilization is a Key Performance Indicator (KPI) that measures the total productive time an agent spends on both calls and other important tasks during their shift. This includes time spent on customer calls, after-call work, training, administrative tasks, and any other job-related duties.

Tracking utilization helps ensure that agents are effectively managing their time across all tasks. However, as with occupancy, too high a utilization rate can lead to overwork, potentially causing stress and reducing the quality of service.

To calculate call center utilization, divide the total productive time agents spend on tasks (including calls and non-call work) by the total time they are available for work, and then multiply the result by 100.

Formula:

Call center occupancy measures the time agents spend on actual calls, while utilization tracks the overall productive time, including calls and other after-call work and administrative duties. While these terms may seem similar, they measure different aspects of an agent's time and productivity.

Here’s a breakdown of the key differences between call center occupancy and utilization.

Call center occupancy primarily measures the percentage of time agents are actively engaged with calls. This includes talk time, hold time, and after-call work (ACW).

On the other hand, call center utilization measures the total productive time an agent spends during their shift. This includes time spent on calls and non-call tasks such as meetings, training, and administrative work.

The ideal range for call center occupancy is usually between 70% and 85%, depending on the call center’s type and workload. If occupancy is too low, it may indicate agents aren’t being fully utilized, while a very high rate could mean they’re overwhelmed, with no time for breaks or after-call work.

For call center utilization, the ideal range is typically 85% to 95%, though this can vary based on the agent's tasks. If utilization exceeds this range, it signals call center burnout, where agents are being overburdened by too many tasks.

The goal of occupancy is to make sure agents are engaged and actively working on calls. It ensures that there’s uniform call distribution among agents and no wasted time.

Utilization, however, is more about maximizing productivity across the board. The goal is to ensure that agents are not only busy on calls but also engaged in other tasks, like after-call work and administrative duties.

Occupancy is helpful for making real-time adjustments in staffing. For example, if agents aren’t able to spend enough time on calls, more staff might be needed. If occupancy is too high, agents might need to be given breaks.

In contrast, call center utilization helps with long-term planning. It lets managers understand how agents are using their time over a longer period. This insight helps in task assignment, training schedules, and employees' workload management.

Occupancy is often measured in short intervals, such as every hour or during each shift. It provides a quick snapshot of how agents are handling calls in real-time.

Whereas utilization is tracked over a longer period, such as daily, weekly, or even monthly. This gives a clearer picture of how agents are spending their entire workday, allowing managers to identify patterns and areas for improvement.

Here’s a quick comparison between call center occupancy and utilization:

Deciding whether to prioritize occupancy or utilization depends on the specific goals and operational needs of your call center. If your focus is on call engagement and ensuring agents are actively speaking with customers, track the occupancy rate. For optimizing overall agent productivity, including both call and non-call tasks, monitor the utilization rate.

Track Occupancy When:

• You need to track how much time agents are actually spending on calls with customers.
• Quick adjustments are needed to ensure efficient call routing and availability.
• You want to reduce wait times during peak hours.

Track Utilization When:

• You want to understand how agents are spending their time throughout the day.
• You need to ensure workloads are balanced across various tasks.
• You are looking for long-term performance insights.

Understanding the difference between call center occupancy and utilization is essential for optimizing operations. Occupancy focuses on how much time agents spend on calls, while utilization gives a broader view of their overall productivity, including after-call tasks.

Tracking both metrics together allows you to make smarter staffing decisions, balance workloads, and ensure high service quality. By focusing on the right performance indicators, you can create a call center that not only meets operational goals but also keeps both agents and customers satisfied.
