20 KPIs Your Support Team Should Track for Customer Service Success

Simply meeting customer expectations isn’t enough, outshining competitors requires delivering an extraordinary customer experience (CX).

Whether it’s empowering customers with self-service tools, offering personalized interactions, or ensuring comprehensive support, businesses have countless strategies to elevate their CX game.

Yet, no matter how polished your approach seems, it’s nearly impossible to gauge its success without reliable metrics to back it up. Enter customer service KPIs, key performance indicators that go beyond just numbers.

These metrics serve as your CX compass, revealing how effectively your strategies are resonating with customers, highlighting areas where your support agents can improve, and uncovering opportunities to build stronger relationships.

By tracking the right KPIs, businesses can align their goals with customer satisfaction and loyalty, ultimately driving long-term success.

This blog dives into 21 essential customer service KPIs every organization should monitor to ensure their CX efforts translate into measurable outcomes and lasting value.

Top Customer Service KPIs

When it comes to customer service KPIs, there’s no universal formula. Every business has its unique set of goals, priorities, and challenges.

What works for one company might not be effective for another. To help you tailor your approach, we’ve put together a list of 21 essential KPIs that will give you valuable insights into how your customer service is performing.

Whether you’re looking to fine-tune your team’s efficiency or enhance customer satisfaction, these metrics will guide you toward achieving your business objectives.

1. Average Resolution Time

Average resolution time measures how long it takes for your support team to close a ticket after it’s been created. This KPI is critical for evaluating how quickly customer issues are addressed and resolved.

To calculate it, you’ll need to figure out the average time it takes to resolve all tickets within a specific timeframe. Let’s say you’re looking at an 8-hour workday. To find the average, divide the total time spent resolving all tickets by the number of tickets your team handled during that shift.

Formula:
Average Resolution Time = Total time spent solving tickets / Total number of tickets solved

By tracking this, you get a clear picture of how efficient your team is and whether there’s room to improve response and resolution speeds.

2. Occupancy

Occupancy measures how much of your customer service team’s time is spent directly engaging with customers or working through tickets. This metric is essential for understanding whether your agents are overburdened or underutilized. It includes all active tasks, such as:

– Responding to customer chats
– Handling phone calls with customers
– Resolving any ticket backlogs

To calculate occupancy, divide the total time spent handling these tasks by the total time your team is logged in and available, then multiply by 100 for the percentage.

Formula:
Occupancy = (Total handling time / Total logged-in time) x 100

3. First Response Time

First response time, or FRT, is the time it takes for a customer service rep to provide an initial response after a customer submits a support ticket. This KPI sheds light on how efficiently your agents can juggle multiple tickets and deal with varying ticket volumes.

To calculate it, take the total time spent by all agents responding to tickets and divide it by the total number of tickets.

For example, if agent A responded in 10 seconds, agent B took 17 seconds, and agent C took 38 seconds, the average first response time would be the sum of those (65 seconds) divided by three, which equals about 21.67 seconds.

Formula:
First response time = Total response time / Number of resolved tickets

4. First Contact Resolution (FCR)

First Contact Resolution (FCR) is a key customer service KPI that measures how often an issue is resolved in a single interaction with the customer. Essentially, it’s about providing customers with a one-and-done solution without the need for escalations or follow-up.

The better your FCR rate, the more efficient your team is, and the more satisfied your customers will be.
To calculate this metric, you divide the number of support tickets resolved in a single contact by the total number of tickets received.

For example, if your team resolves 144 out of 213 support tickets in the first interaction, your FCR rate is 68%.

First contact resolution = (Total number of one-touch tickets / Total number of tickets received) x 100

5. Tickets Handled Per Hour

This metric measures the volume of tickets your customer support team can effectively manage within an hour. It sheds light on an agent’s efficiency and the pace at which they can resolve customer inquiries.

The higher the number of tickets an agent handles, the more efficiently they’re processing requests. However, it’s important to balance speed with the quality of responses to avoid sacrificing customer satisfaction.

To calculate, simply tally up the total number of tickets an agent handles within the given hour.

Tickets Handled Per Hour = Total tickets handled / Number of hours worked

This metric is crucial for understanding how well agents are managing their workload, and helps identify if there are resource or training needs within your team.

6. Tickets Solved per Hour

Tickets solved per hour measures the number of tickets your support agents successfully resolve and close within a given time period.

While closely related to tickets handled per hour, this metric focuses specifically on resolutions, giving you a clear view of an agent’s effectiveness in solving issues rather than just managing them.

This metric is a key indicator of productivity, shedding light on how well your team is addressing customer concerns and how efficient they are at clearing their workload. The higher the number, the more efficient your agents are in closing out customer issues.

7. Customer Satisfaction Score (CSAT)

The CSAT score is a key metric for understanding how well your products or services align with customer expectations. This score directly ties to how customers perceive your business, and ultimately impacts retention rates and churn levels. The higher the CSAT score, the more likely customers are to stay loyal.

There are various methods to measure customer satisfaction, including:

Surveys: Direct feedback from customers on their experiences with your service or product.

Social Media Monitoring: Tracking customer interactions and feedback on social platforms.

First Response Time (FRT) & First Contact Resolution (FCR): These metrics also provide indirect indicators of satisfaction by measuring how quickly and effectively you respond to issues.

Churn Analysis: Observing how many customers leave over a period and the reasons behind it.

Formula for CSAT Score
To calculate your CSAT score, ask customers to rate their satisfaction with a service or product on a scale (typically from 1 to 5 or 1 to 10). Then, calculate the average score.

CSAT Formula:
CSAT= (Total number of satisfied customers / Total number of responses) × 100

A common benchmark is that a score of 80% or higher is considered a positive indicator of customer satisfaction.

While these methods are common, choose the approach that best fits your customer base and business model.

8. Customer Effort Score (CES)

Customer Effort Score (CES) measures how much “work” your customers need to do to get what they want from your company. The simpler the process, the better their experience, and that’s the goal.

Whether they’re hunting for an answer on your website, waiting for help from support, or navigating your service, CES gives you a sense of where customers may be hitting obstacles.

Instead of focusing solely on customer satisfaction, CES zeroes in on how easy or difficult it is for customers to get things done. Companies typically gauge this score by asking customers a few straightforward questions after they interact with support, such as:

– “How effortless was it to resolve your issue with us today, on a scale of 1-10?”
– “What could we have done to make your experience smoother?”
– “Were you able to complete your task successfully with our help?”

The answers to these questions reveal a lot about the friction in your process. A lower CES means your customers are breezing through, while a higher score may indicate that your support flow needs some streamlining.

The focus is simple: reduce customer effort, and you’ll boost satisfaction and loyalty.

9. Employee Satisfaction

Employee satisfaction isn’t just a buzzword, it’s a game-changer for delivering outstanding customer service. A happy, motivated team is more likely to go the extra mile for customers.

Employee satisfaction reflects how engaged, fulfilled, and supported your support agents feel within their roles. It spans everything from job confidence to growth opportunities, work-life balance, and even the overall work environment.

Why does this matter for customer service? It’s simple, when your agents are satisfied, they bring more energy, enthusiasm, and passion to their work, which directly impacts how customers are treated.
To measure and improve employee satisfaction, companies can use:

One-on-one meetings: Personalized conversations where managers can gain deeper insights into individual concerns, provide tailored feedback, and demonstrate their investment in an employee’s growth.

Employee satisfaction surveys: Broad surveys that capture overall sentiment across the team, identifying pain points that might be hindering morale.

Employee Net Promoter Score (eNPS): An insightful metric that gauges how likely employees are to recommend the company to others. A high score indicates a positive, thriving workplace culture.

The key takeaway? Open communication is crucial. Make sure your employees feel heard, supported, and recognized.

When they thrive, your customers do too, after all, happy agents = happy customers.

10. Net Promoter Score® (NPS)

Net Promoter Score® (NPS) is a powerful metric used to gauge customer loyalty and satisfaction by asking one simple, yet profound question: “How likely are you to recommend our product or service to others?”

Scored on a scale from 1 to 10, this survey gives you clear insight into how your customers perceive your business.

Originally developed in 2003 by Fred Reichheld, NPS surveys have become a staple for businesses seeking to understand their customers’ attitudes. This straightforward approach categorizes respondents into three groups:

Promoters (9-10): These are your loyal customers who are likely to recommend your service or product, acting as brand advocates.

Passives (7-8): While they’re satisfied, these customers are not as enthusiastic and may be swayed by competitors.

Detractors (0-6): These customers are unhappy and may share their negative experiences with others, potentially harming your brand’s reputation.

Calculating NPS involves subtracting the percentage of Detractors from the percentage of Promoters, leaving you with a score that can range from -100 to +100. The higher the score, the more loyal your customers are, which can be a strong predictor of business growth.

Understanding your NPS score helps identify where you’re excelling and where you need to improve, making it an invaluable tool for customer experience strategies.

11. Cost per Resolution

Cost per resolution tracks the total expense your business incurs to resolve a single customer issue. This metric gives valuable insight into how cost-effective your customer support operations are, breaking down the financial impact of each solved ticket.

Costs included in this calculation can range from:

Agent salaries: What you’re paying your support staff.

Operational overhead: Rent, utilities, and other day-to-day costs of running your support team.

Tools and software: Subscriptions for help desk tools, analytics platforms, or communication software.

To calculate:
Cost per resolution = Total cost of customer support / Total number of resolved issues

Tracking this KPI regularly helps identify opportunities for cost optimization while maintaining excellent support quality. Whether it’s streamlining workflows or reassessing resource allocation, lowering this metric without sacrificing customer satisfaction is the ultimate goal.

12. Abandon Rate

The abandon rate, commonly associated with call centers, represents the percentage of customers who hang up or leave while waiting for assistance. This metric shed light on customer patience levels and the efficiency of your customer support system.

High abandon rates may indicate long wait times or insufficient staffing, making it crucial to address this issue promptly.

To calculate the abandon rate, you subtract the number of handled calls from the total calls received, divide the result by the total calls received, and then multiply by 100 for the percentage.

Formula:
Call Abandonment Rate = (Number of Calls Received – Number of Calls Handled) / Number of Calls Received) x 100

A high abandonment rate can lead to poor customer satisfaction and tarnished brand loyalty. By analyzing this KPI, you can make informed decisions, like hiring additional agents, improving your IVR system, or offering alternatives like callback features or self-service options.

13. Customer Churn

Customer churn, or attrition, represents the percentage of customers who decide to part ways with your business during a specific timeframe. It’s a critical metric for understanding customer retention and identifying gaps in your CX strategy.

Churn can manifest in various forms, and businesses often use different methods to gauge its impact:

Customer churn: The simplest formula, focusing purely on the number of customers lost.

Gross revenue churn: A deeper dive into how losing customers affects overall revenue.

Adjusted churn: This calculation accounts for new customer acquisitions, offering a more nuanced view for growing organizations.

Seasonal churn: Ideal for industries with predictable demand cycles, like tourism or retail during holidays.

To calculate the standard churn rate, use this straightforward formula:
Customer churn rate = (Customers lost during a period / Total number of customers at the start of that period) x 100

Monitoring this KPI regularly can help you pinpoint issues causing customer loss and implement strategies to boost retention. Addressing churn effectively ensures a healthier customer base and more predictable revenue streams.

14. Ticket Reopens

Ticket reopens measure how often a previously resolved support ticket is reopened by a customer or agent. This KPI provides insight into the quality of issue resolution and the overall customer experience.

A high number of reopens may highlight inefficiencies in first-time resolutions, gaps in product functionality, or miscommunication between support agents and customers.

To calculate the ticket reopen rate, use this formula:
Ticket Reopen Rate = (Number of Reopened Tickets / Total Number of Resolved Tickets) x 100

A lower reopen rate indicates that agents are resolving issues effectively on the first attempt, ensuring customer satisfaction and reducing operational strain.

15. Agent Touches

In customer service, “Agent touches” refers to any action taken by your support team on a ticket. The specific definition of what qualifies as a touch may vary, but generally, it involves tasks like:

– Responding to a customer’s inquiry or updating a ticket with relevant comments
– Providing status updates to the customer or internally to the team
– Closing, reopening, submitting, or reassessing tickets as needed

Simply put, agent touches track every time a support rep directly engages with a ticket. It’s a useful metric for understanding how involved agents are in resolving issues, as well as the number of interactions required to address a single case.

16. Number of Replies

The number of replies is a key customer service metric that tracks how many interactions it takes for an agent to close a support ticket. In customer service, efficiency is everything, less back-and-forth means your team is on point.

If your organization can resolve tickets with fewer replies, it usually suggests that your agents are not only effective but also well-versed in handling customer issues promptly.

17. Customer Wait Time

Customer wait time tracks how long a customer has to wait before a support agent responds to their ticket. It measures the time a ticket spends in open, new, or on-hold statuses.

If this metric is high, it could indicate slow response times, which can lead to frustrated customers.
By using AI Assistants and automated responses you can improve customer satisfaction and demonstrate efficiency in your support team.

18. Customer Retention Rate

Customer retention rate tracks the percentage of customers who stick with your business over time. It’s a key indicator of how well your company is keeping customers satisfied and loyal. Higher retention often signals that your customer experience is on point.

While retention rate is one crucial metric, there are a few other key figures that can also help gauge your retention success, such as:

– Customer churn
– Customer lifetime value
– Repeat customer rate
– Purchase frequency rate

To calculate customer retention rate, use this formula:
Customer retention rate = [(Customers at the end of a period – New customers acquired during a period) / Customers at the start of the period] x 100

19. Volume by Channel

Volume by channel is a customer service metric that tracks how many support tickets come through various channels, such as calls, emails, live chats, and other communication platforms your business uses.

In today’s world, where omnichannel engagement is key, this metric helps you understand where your customers are reaching out from, so you can optimize your support strategies accordingly.

This data can reveal trends in customer behavior, like whether they prefer phone support over chat or email. It can also help you allocate resources effectively, making sure the right team is available on the right channel at peak times.

20. Agent Feedback

Agent feedback is crucial to understanding the pulse of your customer service team.

It gives insight into employee satisfaction and engagement, as well as offering a chance to gather valuable suggestions for improving processes or products.

Collecting feedback can be done through surveys, one-on-one interviews, or regular team meetings.

When employees feel heard and valued, it not only boosts morale but can also lead to more productive and efficient customer interactions. By actively seeking their input, businesses can fine-tune their strategies to better support both the team and customers.

Best Practices for Hitting Your Customer Service KPIs

Achieving success with customer service KPIs isn’t just about tracking numbers; it’s about creating a strategy that’s both effective and sustainable.

Every business operates differently, but there are some fundamental practices that will help you not only track your performance but continually improve it.

Here’s your roadmap to success:

Set Data-Driven Goals
It’s easy to say you want to improve your service quality, but that’s too vague to work with. The key to success is setting precise, measurable goals.

For example, instead of improving customer satisfaction, aim for increase in customer satisfaction by 10% through faster response times and issue resolution. This makes it easier to track progress and know exactly where to direct your focus.

Invest in Consistent Agent Training and Development
Your agents are the backbone of your customer service. Without the right skills, even the best tools can’t save the day.

Regular training sessions on communication, problem-solving, and handling difficult customers will empower your team to deliver exceptional service.

Remember, an agent who feels confident and capable will work faster and with greater enthusiasm, improving both efficiency and the overall customer experience.
 
Monitor KPIs and Actively Adjust Strategies
Don’t set KPIs and then simply forget about them. Performance should be actively tracked and analyzed on a regular basis. Use insights from your data to refine your processes.

If you’re consistently missing targets, ask why and pivot. Sometimes it’s a matter of better resource allocation, other times it’s about identifying bottlenecks or inefficiencies in your workflows.
Keep evolving your approach based on real-time feedback.

Solicit Regular Customer Feedback and Actually Act on It
While customer surveys are helpful, you can’t just stop there. You need to create a feedback loop that’s integrated into your support process.

Set up automated surveys, monitor reviews, and engage with customers directly via social media to get their honest opinions.

More importantly, show your customers that their feedback isn’t just heard, it’s acted upon. This will foster loyalty and help you make tangible improvements.

Leverage Technology to Scale Efficiently
By using Conversational AI Assistants for repetitive tasks and 24×7 support, you can save agents’ time for more complex issues. This gives you both greater efficiency and enhanced accuracy when measuring performance.

Foster a Culture of Accountability and Ownership
When your team is fully bought into the company’s goals, they’ll put more effort into reaching those KPIs.
Establish clear ownership of goals and hold everyone accountable, not just agents, but managers and team leaders as well.

When agents know that their performance is tied directly to their team’s success, they’re more likely to give their best.

Prioritize Personalization in Customer Interactions
Customers today expect more than a generic “thank you” at the end. By empowering your agents to provide personalized experiences such as using a customer’s name or referencing previous conversations, you create stronger connections and improve satisfaction.

Personalized service also helps reduce response time by making your agents more familiar with customer history, leading to quicker resolutions.

Maintain a Flexible Approach to Adapt to Changing Needs
The needs of your customers can change quickly, and so should your approach. Flexibility in managing KPIs is essential.

If you notice that certain KPIs, like first response time, are being impacted by higher-than-usual demand, it’s important to adapt, whether that means adjusting workflows, hiring temporary support, or adding shifts.

Recognize and Reward High Performers
When agents hit or exceed their KPIs, reward them for their hard work. Recognition can be a simple thank-you note, a bonus, or even just public acknowledgment of their contribution.

Rewarding employees not only boosts morale but also motivates others to reach higher performance levels, which directly impacts your KPIs.

Continuous Process Improvement
Think of your customer service operations as a living, breathing entity that can always improve. Regularly evaluate processes for inefficiencies or outdated practices.

Even small tweaks, like adjusting call scripts or refining ticket categorization, can have a big impact on your KPIs. Continuous improvement creates a culture of innovation that helps your team stay ahead.

By combining these best practices with a proactive approach, you’ll be setting yourself up for sustained success. Keep refining your processes, investing in your team, and listening to your customers, and soon you’ll find yourself not just hitting your KPIs but exceeding them.

Final Say

Achieving customer service excellence isn’t just a one-time effort; it’s an ongoing journey that requires focus, strategy, and continuous improvement. By tracking and optimizing KPIs, you’re not just measuring performance, you’re enhancing every interaction between your team and your customers.

Setting clear, actionable goals, investing in agent training, and leveraging the right tools can help transform customer service into a seamless experience that delights.

At the heart of this process is a customer-centric mindset, consistently gathering feedback, analyzing performance, and adapting to new challenges. With these steps, you can not only meet your KPIs but exceed them, all while building stronger, lasting relationships with your customers.
