15 Call Center Metrics Every Manager Should Track

August 9, 202415 MIN READ

In today's fast-paced, innovation-driven world, call centers remain a critical touchpoint for customer service, yet they often operate under significant stress. The reality of call center agent burnout is undeniable, making it crucial to balance agent workload while maintaining top-notch customer service. Accurate and regular measurement of call center metrics is essential to achieving this balance.  

In this blog, we will explore call center metrics from two key perspectives: overall call center performance and individual agent performance. Additionally, we'll share some expert tips on effectively improving these metrics. Let's dive in. 

What are call center metrics 

Call center metrics are quantitative measurements used to evaluate a call center's and its agents' performance. These metrics provide insights into various aspects of call center operations, from efficiency and effectiveness to customer satisfaction and agent performance.    

The key stakeholders responsible for effective measurement of call center metrics are:  

  • Head of CX and customer service: These leaders oversee the call center's overall performance. They use call center metrics to assess strategic effectiveness, allocate resources and drive improvements in customer service strategies.   
  • Customer service managers: They are directly involved in day-to-day operations and use call center metrics to monitor agent performance. Their goal is to ensure SLAs are met and identify areas where additional training or support may be needed.  
  • Call center supervisors: Supervisors focus on operational aspects and use metrics to track real time performance, manage schedules and ensure adherence to processes and standards.  
  • Data analysts: These specialists interpret data from various call center metrics to provide actionable insights and recommendations for performance improvements. 

The importance of tracking call center performance metrics 

Tracking call center performance metrics is essential for several reasons. Here are six key benefits you must know about.   

Driving business impact   

Beyond operational efficiency, call center metrics directly influence the bottom line. Forbes reports that 88% of customers consider customer service more important than ever.  
By identifying trends, bottlenecks and areas of improvement, you can optimize resource allocation, reduce costs and enhance revenue generation.  

For instance, tracking average handle time (AHT) can highlight opportunities to streamline processes, while customer satisfaction scores (CSAT) can inform product or service enhancements.     

Identifying issues early   

Metrics such as call drop rate and customer complaint frequency can indicate potential problems early. For example, a sudden spike in dropped calls might indicate technical issues requiring immediate attention. By dealing with these issues early, managers can take corrective action to check escalations and minimize negative impacts on customer experience.    

Elevating customer satisfaction     

According to call center statistics, 73% of consumers feel that brands valuing their customers' time is a sign of good customer service experiences. You can identify areas where customer needs are unmet by closely monitoring metrics like first call resolution (FCR) and customer satisfaction scores. This data-driven approach enables targeted improvements in call center agent training and results in higher customer satisfaction.    

Optimizing operations   

Call center metrics provide a clear lens into a call center's operational efficiency. By tracking metrics such as call abandonment rate, average hold time and service level, managers can identify bottlenecks, optimize staffing levels and implement process improvements. For example, a high abandonment rate might indicate the need for additional agents or improved IVR systems.     

Empowering agents and boosting morale     

Metrics are not just about the big picture; they also play a crucial role in empowering agents and boosting morale. Call centers can foster a culture of excellence by recognizing and rewarding top performers based on customer satisfaction and first-call resolution metrics. Tracking agent performance metrics can identify training needs and provide call center coaching and development opportunities.     

Data-driven decision making   

The power of call center metrics lies in their ability to inform data-driven decision-making. By analyzing trends and patterns, you can make informed choices about resource allocation, technology investments and process improvements.  

Call center metrics vs. Contact center metrics 

Call centers and contact center metrics assess performance but differ in their approach to customer service. Call centers traditionally handle voice calls, while contact centers manage a variety of communication channels, including calls, emails, live chats and social media interactions. Understanding these metrics’ distinctions can help you better tailor your strategies to meet specific operational needs.

15 Top call center metrics to track   

Let's get to the point now. As discussed earlier in the blog, the key call center metrics are divided into two types: call center performance metrics and agent performance metrics. Let's examine call center performance metrics first.     

  • Call center performance metrics  
    It focuses on metrics that measure the call center's overall health and efficiency. Let's examine the key call center metrics that fall under it.    

1. Service level  

Service level is a key performance indicator that measures a call center's ability to answer calls within a specific timeframe (e.g., 80% of calls are responded to within 20 seconds). It's typically expressed as a percentage. 

Loading...

Interpretation: A higher service level signifies better call center efficiency and customer satisfaction. It's widely used to benchmark performance against competitors and industry standards. It is often linked to customer satisfaction and loyalty.

💡 Fun fact! 
 
Many call centers set aggressive service level targets to meet customer expectations. The "80/20 rule" is a commonly cited industry benchmark for call center service levels, which aims to answer 80% of calls within 20 seconds. While this might sound like a strict target, it's actually a fairly common standard in many call centers!

2. Average handle time (AHT) 

Average handle time (AHT) measures the average length of customer interaction, including talk time, hold time and after-call work (ACW). It's a key indicator of agent efficiency and call center productivity. 

Loading...

Interpretation: A lower AHT generally indicates higher agent efficiency and faster call resolution. However, balancing AHT with other metrics like customer satisfaction is essential to ensure efficiency doesn't compromise quality. Also, AHT is a widely used and closely monitored metric in the call center industry. It's often tied to agent performance evaluations and used to calculate labor costs. 

🤓 Expert’s take 
 
While reducing AHT is often a priority, it's essential to consider the potential impact on customer satisfaction. Excessive pressure to reduce AHT might lead to rushed interactions and negatively impact customer experience. 

3. Abandonment rate 

The abandonment rate measures the percentage of callers who hang up before their call is answered. It's a critical indicator of customer impatience and call center capacity.

Loading...

Interpretation: A high abandonment rate indicates potential issues with call volume, staffing, or wait times. Lowering the abandonment rate is crucial for improving customer satisfaction.

📞 Behind call abandonment  

Call centers often experience peak call volumes during specific times of the day or week. Monitoring abandonment rates during these peak periods can help identify staffing needs and improve resource allocation. 

4. First call resolution (FCR) 

First-call resolution measures the percentage of customer issues resolved entirely on the initial call without requiring subsequent contact. It’s a critical indicator of customer satisfaction and call center efficiency. 

Loading...

Interpretation: A high FCR rate signifies efficient agents, effective problem-solving and improved customer satisfaction. A low FCR rate indicates potential agent training, knowledge, or system limitations issues. 

💡 Pro Tip 

Improving FCR often requires a holistic approach. This includes continuous agent training, regular knowledge base enhancements and timely system upgrades. Additionally, implementing incentive programs can encourage agents to achieve higher FCR rates, thereby contributing to overall improvement. 

5. Average speed of answer (ASA) 

The average speed of answer measures the average time a caller spends waiting on hold before speaking to an agent. It's a critical metric for evaluating call center responsiveness. 

Loading...

Interpretation: A lower ASA suggests better call center responsiveness and customer satisfaction. A higher ASA might signal staffing issues, call volume spikes or system problems. ASA is widely used to measure call center performance against industry benchmarks. 

🔧 How to reduce ASA 

Reducing ASA involves a combination of strategies, including optimizing staffing levels, improving call routing and implementing effective call queuing systems. 

6. Occupancy rate 

The occupancy rate measures the percentage of time agents spend actively engaged in call-related activities, including talk time, hold time and after-call work (ACW). 

Loading...

Interpretation: Occupancy rate indicates how effectively agents utilize their scheduled time. A high occupancy rate suggests efficient use of labor resources, while a low occupancy rate might indicate understaffing or idle time. 

 🔦 Why occupancy rate is tricky 

The occupancy rate is a crucial metric for workforce management and cost optimization. It's often used to determine staffing requirements and schedule adherence.  

An excessively high occupancy rate can lead to agent burnout and negatively impact customer satisfaction. On the other hand, a very low occupancy rate indicates inefficient call center agent utilization

7. Cost per call (CPC) 

The total cost of handling a single call includes agent salaries, infrastructure, technology and other overhead expenses.

Loading...

Interpretation: A lower CPC indicates better cost efficiency. It's essential to balance cost reduction with maintaining service quality. CPC also compares performance across different call centers and identifies cost-saving opportunities.  

Now that you know the key call center performance metrics, let's find out the call center metrics that reflect agent performance and how this works. 

  • Agent performance metrics:
    Call center agent performance metrics assess how effectively your agents handle daily customer interactions. They measure the responsiveness and accuracy of agents in addressing customer inquiries. Let’s examine these metrics. 

8. Adherence to schedule 

Adherence to schedule measures an agent's ability to adhere to their assigned work schedule, including login and logout times, breaks and lunch periods.

Loading...

Interpretation: High adherence indicates discipline and reliability, which contribute to efficient call center operations and help call centers maintain service levels and operational efficiency.

💡 Pro Tip 

In the industry, adherence to schedule is seen as a critical metric for workforce management and is often linked to effective scheduling. While adherence to schedule is crucial for efficient call center operations, a rigid focus on it can backfire. Instead of solely monitoring adherence, consider a more holistic approach that incorporates: 

  • Realistic scheduling: Account for buffer time between calls and potential call volume fluctuations. 
  • Open communication: Encourage agents to communicate scheduling challenges proactively.

9. Average talk time (ATT) 

Average talk time (ATT) measures the average duration an agent spends talking to a customer during a call. This metric helps evaluate the efficiency of interactions and can provide insights into the complexity of customer inquiries. 

Loading...

Interpretation: A moderate ATT indicates that agents resolve customer issues efficiently without rushing. Extremely low ATT might suggest that agents are not spending enough time to fully address customer needs, while very high ATT could indicate that agents are struggling with complex issues or are not managing call time effectively. 

10. After-call work time 

After-call work (ACW) time measures the average amount of time an agent spends completing tasks related to a call after the call has ended. These can include updating customer records, processing transactions and completing any required follow-up actions. 

Loading...

Interpretation: A reasonable ACW time indicates that agents efficiently handle post-call activities without unnecessary delays. However, excessively long ACW times can reduce the overall availability of agents to take new calls, leading to increased wait times for customers. Learn about different types of after-call work

11. Customer satisfaction score (CSAT)  

It measures customer satisfaction with service. This metric is usually gathered through post-call customer surveys, where customers rate their satisfaction on a scale (e.g., 1 to 5 or 1 to 10).

Loading...

12. Net promoter score (NPS) 

Net promoter score (NPS) gauges customer loyalty and how likely they are to recommend your service to others. Customers are asked to rate on a scale of 0 to 10 how inclined they are to recommend the product or services to family, friends or colleagues. 

Typically, the customer’s score determines whether they are promoters, passives or detractors. Here’s how they are categorized.   

- Promoters are satisfied, happy customers who give a score of 9 or above.  

- Detractors are customers unhappy with their experience and give a score between 0 and 6.  

- Passives are satisfied but not fully engaged customers who give a score of either 7 or 8. 

Loading...

Interpretation: A high NPS score indicates that an agent has created a loyal customer. A low NPS score suggests opportunities for improvement in customer experience.
