The way to monitor performance and progress in every aspect of a call center setting is through call center metrics. These measurements are used by businesses to report on call center KPIs (key performance indicators) when aggregated and contrasted across time.
A few important questions can be addressed with the aid of call center performance metrics
- How simple is it for a client to contact us?
- How effectively and swiftly are their problems being handled?
- How satisfied are they with the encounter?
- What areas need work on our end?
Call center software, which can track and analyze both the quantitative side of things (such as the number of calls answered and active waiting calls) and more qualitative data, is typically used to measure call center performance indicators. (such as client sentiment and effort).
Without first assessing how things are currently doing and then comparing those results to past and future performance, it is impossible to improve any aspect of your company. There are pertinent metrics to monitor in every department of your company, and the call center is no exception.
This is because the call center, which serves as the hub of a conventional customer support system, is still a crucial component of the customer experience. This means that creating an exceptional customer experience requires monitoring performance across a variety of measures, from agent productivity to customer issue resolutions, and acting on the data that these indicators reveal.

Common Call Center KPIs
In the dynamic environment of call centers, Key Performance Indicators (KPIs) are crucial for monitoring and enhancing various aspects of operations. These KPIs are categorized into several groups, each reflecting critical areas of focus that contribute to the overall effectiveness and efficiency of call center services.
Below, we delve into the essential KPIs categorized under Customer Experience, Agent Productivity, Call Initiation, and Call Center Operations, providing insights into how each metric directly influences the quality of service and operational success.

Customer Experience
Explore how KPIs such as First Contact Resolution (FCR), Customer Satisfaction Score (CSAT), and Net Promoter Score (NPS) are instrumental in gauging and improving the customer experience in call centers. These metrics provide invaluable insights into customer satisfaction and service quality.

- First Contact Resolution (FCR): Measures the ability of agents to resolve a customer’s issue during the first interaction.
- Customer Satisfaction Score (CSAT): Assesses the satisfaction level of customers after a call or interaction.
- Customer Effort Score (CES): Evaluates how easy it is for a customer to get their issue resolved.
- Net Promoter Score (NPS): Gauges customer loyalty based on their likelihood to recommend the service to others.
Agent Productivity
Focus on key performance indicators that measure agent efficiency and effectiveness, such as Average Handling Time (AHT) and Agent Utilization Rate. These metrics help manage performance and ensure agents are maximizing their impact on customer interactions.

- Average Handling Time (AHT): The average duration from the start to the end of a transaction, including hold time and after-call work.
- Agent Utilization Rate: Measures the percentage of time agents spend in active calls compared to idle time.
- Average Speed of Answer (ASA): The average time it takes for an agent to answer an incoming call.
Call Initiation
Examine the critical KPIs involved in the initial stages of customer interaction, including First Response Time (FRT) and Percentage of Calls Blocked. Understanding these metrics can help optimize how quickly and efficiently customers are connected to agents.

- First Response Time (FRT): The average time it takes for the first response to a customer inquiry.
- Percentage of Calls Blocked: The percentage of incoming calls that cannot be connected due to capacity issues.
- Average Call Abandonment Rate: The rate at which customers disconnect before reaching an agent.
- Active Waiting Calls: The number of calls that are actively waiting to be connected to an agent.
Call Center Operations
Delve into the operational metrics that keep a call center running smoothly, such as Calls Handled, Cost Per Call (CPC), and Call Arrival Rate. These indicators are essential for managing the overall operational health and efficiency of call center services.

- Calls Handled: The total number of calls received and managed by the call center.
- Cost Per Call (CPC): The average cost incurred for each call handled.
- Call Arrival Rate: The number of calls arriving at the call center within a given time frame.
- Peak Hour Traffic: Measures call volume during the busiest hours.
- Average Call Lengths: The average duration of calls within a specific period.
- Average Age of Query: Indicates the average time unresolved customer queries remain open.
- Callback Messaging: Tracks the number of customers opting for a callback option.
- Repeat Calls: Measures the frequency of customers calling back regarding the same issue.

As you see in the image above, Amazon and Zappos use an ‘online only/in-house supply,’ while IKEA, Walmart, and other retailers use brick-and-mortar stores as distribution channels. Small and medium-sized e-commerce businesses usually rely on sales when it comes to measuring success.
And that’s a good thing if someone is monitoring the website’s performance by tracking key indicators such as conversion rate, cart abandonment rate, and revenue per visitor.
While tracking basic metrics like conversion rates and cart abandonment provides a snapshot of website performance, it’s imperative to dig deeper to fully understand customer behaviors and business outcomes. Advanced analytics such as customer lifetime value, return on advertising spend, and customer retention rates offer more detailed insights.
These metrics allow businesses to fine-tune their strategies, better predict future trends, and allocate resources more effectively. Integrating call center data with these analytics can enrich understanding, enabling a more responsive and customer-focused strategy that drives repeat business and sustainable growth.
However, these are just the basic metrics that could give an overview of the website’s performance. The truth is that they do not help marketers predict repeat purchases, sales, profits, or churns. The measure of performance varies wildly from one industry or business model to another. Furniture, for example, is not as easy to sell online as shoes, electronics, books, and other similar products are.
Thus, retailers have to consider call center services, and, more importantly, they should focus on recruiting experienced strategists or managers who will measure and monitor their team’s results.
The 5 Call Center Metrics That You Should Care About

The First Call Resolution Rate
It is the percentage of completed transactions within a single contact call from the total number of calls. This indicator is a measure of quality because it relies on the person’s skills to give all of the required information and to convince customers to complete the purchase.
The customer’s perception of the quality of a company’s services is highly influenced by his interaction with the call center. Regardless of the quality of the products and the website’s offers, the customer’s perception of the company’s brand is influenced by all of the factors that may appear during a completed purchase.
Thus, call center managers should always recruit experienced hands. The alternative is to train the recruits, but the opportunity cost is the one that will decide the most suitable approach for the company’s benefit.
Forecasted Average Handle Time vs. Actual Average Handle Time
Firstly, the average handle time is the total amount of work hours related to calls. It involves the Average Talk Time and the Average After Call Work Time. It is important to understand the need to include the after-call work time in calculating this indicator due to the well-known fact that time is the most precious resource. No matter how good your team is at closing a deal on the phone, you should know the after-call work time because it will determine the workforce required.
Comparing the forecast of the average handle time with the actual time is a measure of performance both for the call center team and the manager. The manager is the one responsible for his team’s motivation level and results. Thus, the comparison is the second most important to determine the appropriate workforce required.
Cost Per Contact
It is probably the most popular indicator within many industries. In pay-per-click campaigns, its equivalent is the Cost per Click, while lead generation marketers name it Cost per Lead. Therefore, do not confuse “contact” with “customer acquired within a phone call”.
Calculating the cost per contact does not take into account whether the call ended up with a conversion or not. In this case, conversion is the successful attempt of the company’s employee to close up the deal.
Customer Satisfaction
It is the measure of the overall satisfaction with the customer’s interaction with the call center. Not only that measuring satisfaction involve getting feedback from the company’s customers, but it also gives insights on improving either the products, the offers, or other aspects that could determine or maintain a competitive advantage.
Measuring customer satisfaction is not an easy task, because of the difficulty of scaling and measuring attitudes, opinions, and behaviors in marketing research. The time invested into getting feedback from customers and analyzing their suggestions and complaints is more valuable than investing in online marketing campaigns meant to drive more traffic to the website.
Keeping an existing customer satisfied counts for 7 newly acquired customers. It is clear now why this indicator plays a vital role in achieving success in the tough competitive retail market.
Service Level
It is the percentage of calls answered within a specific period(in seconds). It is often reported daily or weekly, due to its importance regarding the customer experience. The average value for this indicator is 80% of calls answered within 20 seconds.
Managing an e-commerce business is not an easy thing to do, and everyone involved in this industry knows it. Even though the focus should go on the 20% of the business resources that drive 80% of sales, the company’s brand is more valuable in the long run than sales. Thus, make sure to hire professional people for your call center and pay attention to every communication that your company is addressing to its target audience.
How is the effectiveness of call centers measured?

The amount of calls handled at a call center has historically been used to gauge its efficiency. Your “Call Center Service Level” can be calculated by simply keeping note of the number of calls that are answered within a specified period.
It is simple to detect that performance is tracking below normal if, for example, you establish that, based on existing averages, your call center personnel should be answering 50 calls per hour, but they are only answering 30 at any given hour. And in that situation, you should increase your efficiency.
In addition to this, contact centers have consistently worked to meet several industry-standard benchmarks, such as making sure that ringing calls are returned within 20 seconds.
However, in the contemporary call center setting, customer experience and efficiency are inextricably linked since they influence each other constantly. In practical terms, this means that monitoring more than simply operational data in its raw form is essential.
As many indicators as you can track at the same time, and then pay close attention to any trends or related metrics that indicate areas of concern. Using call center software, which can automatically monitor everything from raw operational information to more experienced, human data, is the best method to accomplish this.
In light of this, let’s examine several ways that the appropriate software can help to optimize and enhance every call center measure.
Why Call Center Metrics Are Vital for Business Success

The significance of call center metrics cannot be overstated; they are the backbone of understanding and improving your call center’s performance. With accurate tracking and analysis, you can make informed decisions that directly influence customer satisfaction and business outcomes.
Impact of Effective Metric Management
When call center metrics are managed effectively, they provide critical insights into how customers interact with your business, highlighting areas of strength and those needing improvement. An efficient call center translates to happy, loyal customers who are likely to share positive experiences, enhancing your brand’s reputation and customer loyalty.
Consequences of Poor Metric Management
Conversely, inadequate attention to these metrics can lead to customer dissatisfaction. Studies, such as those by Accenture, show that around 52% of customers in the US and UK will switch to a competitor following poor customer service experiences. Of these, 90% indicated that an immediate response from the call center is crucial to their satisfaction.
The Role of First Contact Resolution
The importance of resolving issues on the first call cannot be understated. Data shows that companies achieving this see nearly 99% of those customers remain loyal, whereas if follow-up calls are necessary, loyalty drops significantly to 85%. Ensuring that customer problems are resolved quickly and effectively not only maintains loyalty but also reduces the operational cost associated with multiple follow-ups.
The Enduring Value of Human Interaction
While digital channels continue to grow in popularity for customer service, the value of direct human interaction remains high. Many customers still prefer the clarity and immediacy of speaking to a person, especially for complex issues. Research indicates that 41% of Americans still use a landline to contact customer service, expecting the same level of service as digital channels.
Consistency Across Channels
Providing a consistent customer experience across all channels is now a baseline expectation, with Salesforce reporting that 75% of consumers expect uniformity across interactions. Failure to meet these expectations can lead to a 73% customer turnover rate. Thus, integrating digital solutions without compromising the quality of traditional call center interactions is essential.
Navigating Economic Challenges
In economically tight times, expanding digital offerings without sacrificing call center quality becomes even more crucial. Routine measurement of call center metrics allows businesses to identify and address gaps in customer experience proactively, ensuring that every interaction adds value to the customer journey.
Quote to Reflect On
Jim Rohn once remarked, “One customer well taken care of could be more valuable than $10,000 worth of advertising.” This underscores the intrinsic value of excellent customer service and the profound impact of effective call center management on a business’s success.
By focusing on these key points, you can ensure your call center continues to contribute positively to your overall customer service strategy, driving satisfaction and loyalty even in challenging economic times.

Say what you want about the BPO/ call center industry, but one thing that we can’t deny is the business model works like a charm. It’s a good idea to channel some of their best practices in other businesses, including e-commerce, as you’ve pointed out here. And excellent Bieber GIF, by the way. Got me chuckling.
Well call centers are now an essential part of e-commerce businesses so a good know-how of all the metrics could add an advantage event if you outsource your call center operations.
I agree that customers’ satisfaction is essential and getting good feedback from them is token for any business since it will give you insights for improvement. And you make a good point that by getting feedback from customers, it gives you a chance to analyze and think about all their suggestions and that to me is valuable.
Great article Elena! I have to say that people usually underestimate the BPO in general but they don’t understand the whole story about it. How the BPO industry is a big help in the economy of a specific country. For starters, it gives several individuals who couldn’t afford to study opportunities to actually help lift the economy without having a degree by being a taxpayer. It can be a stepping stone for other people to actually obtain one if one strives for it.
