Call Center KPIs to Track for Success

Share This

The term “call center” today has a diverse meaning, especially in our new age of remote work and self-help tools available through government, school, healthcare and customer service outlets. While each industry has different goals, analyzing call center key performance indicators (KPIs) is imperative when assessing the effectiveness and efficiency of a call center. While it is clear to most call center managers and decision-makers that they need to analyze call center KPIs, what is often not so clear is which contact center metrics to measure and track over time. This blog post will help with just that. It lists and describes the top 12 call center KPIs to track for success.

1. Percentage of Calls Blocked

A call center KPI that has a large impact on customer satisfaction is the percentage of calls blocked. This is the percentage of inbound callers that received the busy tone when they call and is often caused by one of the following:

  • There are no available agents and no call queues configured (or the call queues are full) so callers hear a busy tone when they call or are routed directly to voicemail
  • The call center software can not adequately handle the call volume

As even one blocked call can be a missed opportunity to connect with a customer or prospect, this is a call center KPI that should never be ignored.

2. Average Time in Queue

No one wants to wait in a queue for a long period of time. Thus, in order to ensure your callers’ wait time is within an acceptable range – and customer satisfaction is as well – you must keep track of the average time in queue. This metric is the total time callers wait in call queues divided by the total number of calls answered by agents. It is a great indicator of whether or not your team is providing their callers with the service they deserve.

3. Average Abandonment Rate

Call abandonment, or the percentage of callers who hang up before reaching an agent, is a common occurrence in the call center and has a detrimental impact on customer retention. It is therefore imperative that customer-centric call centers keep track of this KPI and make sure that it remains below a target threshold.

4. Service Level

Service level is the percentage of calls answered within a specified number of seconds. This call center KPI is typically displayed in real-time to both agents and managers in their call center software metrics dashboard so they can make data-driven decisions that will have an impact on keeping this KPI within an acceptable range.

5. Average Speed of Answer

The average speed of answer is the average time it takes for calls to be answered in the call center during a specific time frame. This includes time spent waiting in a queue and while the agent’s phone rings however does not include the time it takes to navigate through the IVR system. It is a call center KPI typically referenced by managers when assessing their team’s efficiency and degree of accessibility to their callers.

6. Average Handle Time

Average handle time is the elapsed time from when an agent answers a call until the agent disconnects. It is one of the most commonly analyzed KPIs in the call center industry as it is directly related to caller satisfaction.

7. Average After Call Work Time

In most call centers, an agent’s work does not end when they finish a call. In fact, they often spend quite a bit of time updating databases, sending emails and informing teammates about the call. This time an agent spends completing a transaction after the caller has disengaged is called after call work time. Managers often seek to reduce after call work so that they can maximize the time their team spends interacting with customers while they are on the clock.

8. First Call Resolution

First call resolution is another KPI that is directly related to customer satisfaction – and it is easy to see why. It is the percentage of calls that the agent completely addresses the caller’s needs without having to transfer, escalate or return the call. Resolving an issue on first contact is so important, that many claim that first call resolution is the single most important KPI related to a customer’s level of satisfaction with a company. It therefore should be at the top of any list of call center metrics to track over time.

9. Customer Satisfaction

Customer satisfaction is a KPI that can be acquired from many different sources. Call centers typically arrive at a customer satisfaction score by conducting customer surveys as well as obtaining quality assurance measurements. Regardless of the methodology used to arrive at this KPI, it is one that should always be considered when analyzing call center effectiveness and efficiency.

10. Occupancy Rate

Occupancy rate measures the amount of time agents are on live calls, as well as any work associated with the calls. While most call center managers seek to optimize occupancy rates, they must also be cognizant of agent stress, as well as agent workload, when setting targets for this call center KPI. One of the best ways to set targets for employees to try and optimize work is by using OKR software like that of Profit. It allows you to choose key result action types, before adding milestones and a value measured through KPI, all with an accompanying target date

11. Agent Absenteeism

Agent absenteeism, or the number of days lost per year due to agents being absent as a percentage of the total number of contracted days, can have a major impact on call center scheduling and staffing as well as their bottom line. It is therefore a KPI that can be helpful in developing a budget as well as optimizing workforce management practices.

12. Agent Turnover Rate

The final call center KPI that should be included in every call center manager’s list of metrics to track over time is agent turnover rate. This is the percentage of agents who leave the call center to work elsewhere. Agent turnover rate significantly impacts customer satisfaction, call center scheduling and team morale, thus it should be included on a list of contact center metrics to track over time.

Key Takeaways

Measuring call center KPIs that are associated with customer satisfaction, agent effectiveness and call center efficiency should be the main objective of any manager seeking to optimize their call center’s performance. And keeping track of the 12 aforementioned KPIs is a great place to start.
