Top 10 Most Used Call Center Metrics and KPIs

Call centers track specific metrics and KPIs (Key Performance Indicators) to improve customer service processes and increase operational efficiency. Measuring the right metrics increases customer satisfaction while allowing call center operations to be managed more efficiently. Here are the 10 most commonly used metrics and KPIs in call centers:

1. Average Abandoned Call Rate

The average call abandonment rate indicates the percentage of customers who end the call before meeting with a representative. A high dropout rate may indicate long wait times or insufficient agent capacity.

How to Heal?

• Optimize the IVR system (Interactive Voice Response).
• Assign enough representatives to reduce waiting times.
• Increase customer satisfaction by offering a callback option.

2. Percentage of Blocked Calls

The percentage of blocked calls is the rate that customers get busy tone before they can reach the call center or are blocked by the system. This metric assesses the adequacy of the call center infrastructure.

How to Heal?

• Increase system capacity.
• Offer alternative communication channels to balance the call center's rush hour load.

3. Average Queue Standby Time

This metric shows how long customers wait on average before connecting with an agent. Long wait times can reduce customer satisfaction.

How to Heal?

• Do call forecasting and workforce planning.
• Strengthen self-service options.

4. Service Level

The level of service refers to the percentage of calls answered in a certain period of time. For example, a target of “80% of calls answered within 20 seconds” can be set.

How to Heal?

• Optimize call routing systems.
• Adjust the number of agents according to the call volume.

5. Average Speed of Answer (ASA)

ASA measures the time it takes for a representative in the call center to answer the call. Low ASA is a positive indicator in terms of customer satisfaction.

How to Heal?

• Develop automated call distribution systems.
• Improve call center workforce planning.

6. Average Handling Time (AHT)

The average processing time is the total time it takes for a call to complete. Includes call time and post-call operations.

How to Heal?

• Get access to better information for agents.
• Automate customer service processes.

7. Average After Call Work (ACW)

ACW is the amount of time the agent spends completing transactions after the end of a call. High ACW duration can reduce the efficiency of the agent.

How to Heal?

• Provide automation by integrating CRM systems.
• Speed up operations by training agents.

8. First Call Resolution (FCR)

First contact resolution rate measures the percentage of a customer problem being solved on the first call. High FCR increases customer satisfaction and reduces repeat calls.

How to Heal?

• Increase the level of training of representatives.
• Use systems that provide quick access to customer history.

9. Customer Satisfaction Score (CSAT)

Customer satisfaction score measures how call center service is evaluated by the customer. It is usually collected through surveys.

How to Heal?

• Improve the communication skills of representatives.
• Offer more personalized services.

10. Net Promoter Score (NPS)

The NPS measures how likely customers are to recommend the company to others after their call center experience. It is determined by a rating of 1-10.

How to Heal?

• Pay attention to customer feedback.
• Provide proactive customer support services.
