10 Key Metrics to Benchmark Your Call Center Performance




When it comes to operating a call center, benchmarking is a crucial tool for measuring and improving performance. By comparing key metrics against industry standards, businesses can gain valuable insights into their call center’s effectiveness and identify areas for improvement. In this blog post, we will explore the importance of benchmarking call center performance and highlight ten key metrics that play a vital role in assessing success.

Customer Satisfaction Metrics

One of the primary goals of any call center is to ensure customer satisfaction. To measure this, several metrics are commonly used:

Net Promoter Score (NPS)

The Net Promoter Score is a widely used metric that gauges the loyalty and satisfaction of customers. It is calculated based on responses to a simple question: “On a scale of 0-10, how likely are you to recommend our call center to a friend or colleague?” Customers who rate their likelihood as 9 or 10 are considered promoters, while those who rate 0-6 are detractors. The NPS is calculated by subtracting the percentage of detractors from the percentage of promoters.

Customer Satisfaction Score (CSAT)

The Customer Satisfaction Score is another important metric used to measure how satisfied customers are with their call center experience. It typically involves asking customers to rate their satisfaction on a scale of 1-5 or 1-10. This metric provides a snapshot of customer satisfaction levels and can help identify areas that need improvement.

Customer Effort Score (CES)

The Customer Effort Score measures the level of effort a customer had to exert to get their issues resolved. It focuses on the ease of the customer journey, aiming to reduce any unnecessary obstacles or challenges. A lower CES score indicates a better customer experience, as it signifies that customers found it easy and effortless to interact with the call center.

Service Level Metrics

Service level metrics determine how quickly calls are answered and resolved, providing insights into call center efficiency. Here are three key metrics worth monitoring:

Average Speed of Answer (ASA)

ASA measures the average time it takes for calls to be answered by call center agents. It is crucial to track ASA, as excessively long wait times can lead to frustrated customers and decreased satisfaction rates. By analyzing ASA, call centers can identify if they need to adjust staffing levels or optimize call routing processes to improve response times.

Average Handle Time (AHT)

Average Handle Time represents the average duration of a call, including both the time spent speaking with the customer and any associated after-call work. Monitoring AHT helps call centers identify areas for efficiency improvements, such as streamlining call scripts or providing additional training to agents to reduce handling time without compromising service quality.

First Call Resolution (FCR)

First Call Resolution measures the percentage of calls that are resolved without the need for further contact or escalations. A high FCR rate indicates that call center agents are knowledgeable and capable of effectively resolving customer issues on the first attempt. Achieving a high FCR rate not only enhances customer satisfaction but also reduces operational costs by minimizing call volumes and repeat contacts.

Productivity Metrics

Monitoring productivity in a call center is crucial to ensure optimal utilization of resources. Here are three key productivity metrics:


Utilization measures the percentage of time agents are occupied with active calls or tasks compared to their total available working time. Monitoring utilization provides insights into staff capacity and determines whether the call center is optimally staffed or if additional agents are required to meet demand.


Occupancy measures the amount of time agents spend handling calls or engaged in work-related activities. A high occupancy rate indicates that agents are consistently busy, but excessively high rates can lead to agent burnout and decreased productivity. Finding the right balance of occupancy helps maximize agent efficiency while giving them the necessary time to recharge and take breaks.

Agent Adherence

Agent Adherence measures how closely call center agents follow their assigned schedules and adhere to the defined processes and protocols. Low adherence rates can lead to inconsistent customer experiences and impact service levels. Regular monitoring of agent adherence allows call centers to take corrective action, provide additional training, or address any underlying issues affecting agent performance.

Quality Metrics

Ensuring call quality is essential for delivering an exceptional customer experience. Here are two key metrics for monitoring call center quality:

Call Monitoring

Call Monitoring involves regularly evaluating call center agents’ interactions with customers to ensure they adhere to quality standards and customer service best practices. Call monitoring can be conducted in real-time or through reviewing recorded calls. It provides valuable insights into agent performance, identifies areas for improvement, and helps maintain consistent service quality.

Customer Complaints

Customer complaints can be a powerful indicator of call center performance and customer satisfaction levels. Tracking and analyzing the number and nature of customer complaints not only helps identify specific issues but also provides an opportunity to implement corrective measures and prevent similar complaints in the future.

Operational Metrics

Operational metrics measure call center performance from an operational standpoint. Here are two important operational metrics:

Abandonment Rate

The abandonment rate represents the percentage of customers who hang up or disconnect before reaching a call center agent. A high abandonment rate can be problematic, as it may indicate poor call routing, lengthy wait times, or inadequate staffing levels. Monitoring the abandonment rate helps identify potential issues and improve overall call center efficiency.

Service Level Agreement (SLA) Compliance

SLA compliance measures the percentage of calls that are answered within a specified time frame, commonly set as a target in service level agreements. Monitoring SLA compliance ensures that call center operations align with customer expectations and contractual commitments. Understanding any deviations from SLA targets allows call centers to address performance gaps and make necessary adjustments to meet service level requirements.

Cost Metrics

Monitoring cost-related metrics is crucial to achieve optimal cost-efficiency in call center operations. Here are two key cost metrics of interest:

Cost per Call

Cost per Call measures the average cost incurred by the call center for handling each customer interaction. It takes into account various factors, such as agent labor costs, technology expenses, and overheads. Tracking and optimizing cost per call helps call centers identify opportunities for cost reduction without compromising service quality.

Average Call Transfer Rate

The average call transfer rate indicates how often calls need to be transferred to other agents or departments for resolution. High transfer rates can lead to customer frustration and increased handling time, impacting overall call center efficiency. Reducing transfer rates through better training, improved knowledge bases, or enhanced call routing protocols can significantly enhance customer satisfaction and operational effectiveness.

Reporting and Analysis

Tracking and analyzing call center metrics is only the first step. To drive continuous improvement, it is essential to leverage the insights gained from the reported data. By conducting regular reviews and analysis, call centers can identify trends, patterns, and areas where performance falls short. These insights can then be used to implement targeted improvements, whether through agent training, process enhancements, or technology upgrades.


Optimizing call center performance requires a thorough understanding of key metrics and benchmarks. By continuously monitoring and evaluating key performance indicators such as customer satisfaction, service levels, productivity, quality, operations, and costs, call centers can identify areas for improvement and drive customer-centric experiences. Remember, regularly reviewing and updating benchmarks is essential to adapt to changing customer expectations and maintain a competitive edge in the call center industry.
