All the call center metrics and KPIs are measured using particular algorithms and formulae. There is a simple formula to evaluate your agent’s productivity that will help you monitor the productivity of all your customer-related services.

Top Call Center Metrics and KPI

Now, let’s finally dive into some metrics and performance evaluators to calculate your agent’s and the call center’s productivity.

1. Average Handle Time(AHT)

Average Handle Time is a KPI that helps you handle the average time that your agent spends on each call. You can know the progress by the duration of the call, and the shorter it is, the faster the problem is solved.

This KPI tracks the call duration from which the agent receives it until the ticket is closed. The measure includes the total amount of time the agent spends on one customer.

The main intention of using this KPI is to measure the minimum and maximum call duration it takes to solve your customer’s problem, pin their address, and everything necessary. After you know the extreme time points, you can brief your agents to try to finish the call within them.

2. First Response Time

First Response Time is a KPI that measures the time between a problem issued by the customer to when an agent addresses it. The FRT should be encouraged to have less time so that productivity is increased.

The sooner you address your customer’s problems, the better customer service they experience. It is crucial to make your customers have a good service by providing them with an instant solution to their problem addressed on time.

3. Average Speed to Answer

The average time speed to answer is a metric that can evaluate your agents’ time to answer a customer’s call. Making your customer wait for a long time will degrade the customer experience, not giving you a good outcome.

According to the study done by a Call center helper, 80% of the calls are answered in 20 seconds, making the average time the calls are answered 28 seconds. 

4. Call Abandonment Rate

The call abandonment rate refers to the average number of callers who hang up the phone before getting addressed by any agent or reaching out to them. The hang-up call phenomenon is very common among call centers.

You will not show great performance to your callers if they don’t reach your agents. The increasing call abandonment rate shows some problems with all of the agent’s productivity instead of individual agents.

Not all employees will remain active and productive throughout the day. Due to tardiness and long breaks during office working hours, their productivity diminishes greatly. These types of behaviors due to which call center agents are unable to perform their tasks despite being paid for the job is called call center shrinkage.

Shrinkage in a call center is a measure of the number of agents available to make calls vs the number of agents needed to make calls. It can be calculated by using the following formula.
