Key Call Metrics

 As you just read, there are numerous call center metrics to track, but just a few key performance indicators (KPIs) should be monitored regularly.

Below is a list of the 3 most important and relevant call metrics you must keep track of.

Call Metrics to track

1. Customer Satisfaction (CSAT)

It is probably the most important call center KPI. This indicator assesses how satisfied your consumers are with your service. According to a poll of 350 professionals, 93.1 percent of employees say CSAT is the essential overall data point for determining the success of their department.

CSAT is also one of the most straightforward measures to estimate. To collect results, send a follow-up survey to your customers through text or email. Then you’ll compute your score using a simple equation: the number of satisfied customers divided by the total number of customers evaluated.

There is no “cutoff point” for the CSAT score that you should obtain. Finally, your team should use this number to keep track of milestones and performance. In an ideal scenario, your CSAT would always be 100 percent; if not the case, you should consider what you can do to improve your score. Assume for a moment; your CSAT score is approximately 90 in a month; then, you should work on improving that score and take it to 95 in the next month, and then from there, strive to improve on a regular basis.

2. First Call Resolution (FCR)

The capacity of your staff to handle a customer’s issue the first time they call is referred to as first call resolution (FCR). 

Customers want their concerns resolved fast, and they don’t want to waste a day or more time on hold with your contact center employees. They would prefer to call your staff only once in a while and have their problem fixed without having to hang up, redial, or be transferred.

You can also get FCR statistics by asking how many calls it needed to address an issue in a follow-up survey or by looking at customer data to see how often a customer called about the same issue until it was tagged as resolved.

3. Call Source

Knowing which campaigns and ads generate the most calls allows you to allocate your marketing budget and efforts where they are most effective.

But how can you get this information if your phone number appears on your website, in newspapers, on a social media platform, or in advertisements?

You should utilize unique tracking numbers to advertise in various channels to ensure a successful call tracking and reporting strategy. Instead of using a static monitoring number for online activity, you should use dynamic phone numbers.

You can see which of your advertising channels produces the most calls by looking at detailed information for the dialed number. With a quick setup, you can easily track the performance of each campaign.

When you choose Dynamic Number Insertion (DNI) over average static phone numbers, you receive many benefits. Dynamic phone numbers provide the user with a tracking number based on their online journey trip and reveals which ad, keyword and campaign they clicked to get to your website.


Call metrics are one of your company’s most vital and influential aspects that should not be overlooked. It affects your company’s performance to a significant extent. To get a more transparent idea of your team’s efficiency, set KPIs and track these call center indicators. After you’ve achieved a baseline number, you may begin defining improvement targets at regular intervals. Every change takes time. Hence, if you wish to maintain a stable agent turnover rate, make sure to set realistic and short-term goals and implement changes gradually.
