Understanding Call Metrics

Call metrics and KPIs are two terms that are connected to analyzing call data. It’s important to understand both terms as you build your call center so you can maximize your results. While the terms are intrinsically connected, there are some distinct differences between them.

Call metrics track the status of your calls. On the other hand, KPI stands for key performance indicator. Call center KPIs reflect measurable values that track performance toward your business goals. In a nutshell, call metrics track call center processes and KPIs tell you how close you are to hitting your targets.

Analytics give you a goldmine of information for running a successful call center. There is so much to gain when you learn which metrics to follow and how to set goals for KPIs. The right software solutions help you track the metrics that provide the greatest amount of insight in real-time, regardless of the teams location.

Advanced call metrics and KPIs give you specific insight to target areas for improvement, which will help your business overall. The right data is extremely beneficial for your call agents too because it gives you detailed information about each call agent’s performance and valuable insight as to how they handle calls. The right data helps you form the basis for giving each call agent specific feedback and work with them to make regular progress toward meeting established goals.

There are so many insights that you can gain from call metrics and so many ways to use the data you collect, so we’ll focus next on the top 10 metrics that are most important for your business.

What Metrics Should You Be Tracking?

There’s no doubt that a well-performing call center is the key to addressing your callers’ needs professionally and expediently. You’ll be well on your way to improving your call centers’ performance when you track and evaluate the following call metrics and KPIs.

  1. Average call length

  2. This metric is helpful for understanding how long your call agents spend on an average call. It’s most useful when you use it to establish a baseline for call length that prevents wasting time and still allows enough time for call agents to deliver personalized service and resolve customer issues professionally.

  3. Number of calls answered

  4. Use this metric to identify which call agents are answering too many or too little calls. When you know the average number of calls each agent can answer, you can better plan to scale up or down and plan more accurately for peak periods.

  5. Average speed of answer

  6. While customers prefer phone contact, they’re not always patient. states that the industry standard is for call center agents to answer 80% of calls within 20 seconds. If you’re already there, the next goal could be to answer 90% of calls within 15 seconds.

  7. Average wait times

  8. The 2019 eCommerce Customer Experience Study showed that 89% of customers will drop off the line if they have to wait up to five minutes. If your calls aren’t being answered quickly enough or customers are waiting too long on hold, it may be time to hire more call agents, add shifts, or shift your resources.

  9. Number of missed calls

  10. A missed call is a missed opportunity to resolve a problem or make a sale. Even if customers use an alternative channel to contact you, if it’s too difficult for customers to reach you, they’ll be irritated when they make contact. Too many missed calls could mean it’s time to scale, answer calls more quickly, or shorten the average length of calls.

  11. Average amount of time to return a missed call

  12. If you miss a call, you can call a customer back. A quick callback may relieve some of a customer’s frustration. You’re apt to lose the loyalty of callers that feel ignored.

  13. Conversion rate

  14. This metric tell you how many calls it takes to make a sale. Additionally, you can use it to pinpoint training issues for salespeople that are struggling.

  15. First-call resolution

  16. This metric tells you whether customers are getting help on the first call. If the percentage is too low, using call routing or an IVR can help route calls to someone that can help right from the start.

  17. Customer call frequency

  18. Customers that call repeatedly usually have a problem they need help with. Too many calls about the same problem give you a place to target for improvement.

The Importance of Call Center Agent Performance Metrics
