Want to improve customer service? Then you need to measure the right metrics. To help, we compiled a list of 12 incredibly useful customer service KPIs you need to start tracking for your business.
Generally, customer service KPIs can be useful for:
So, key performance indicators (KPIs) have various good uses. It’s down to you to use each customer service performance metric in a way that works best for your business.
Let's get started.
Net Promoter Score (NPS) reflects how likely customers are to recommend your company to others. Essentially, it’s a proxy for customer satisfaction and brand loyalty.
NPS surveys can be administered via pop-up or email. Customers are asked “How likely is it for you to recommend us to someone else?” and can reply on a scale from 0 to 10. Based on their answer, customers are classified as promoters (9-10), detractors (0-6), or passives (7-8).
You can also ask for feedback on their score, plus follow-up questions. This will give you a better understanding of your customer's perspective.
Net Promoter Score is the percent of promoters minus the percent of detractors, which can be a number between -100 and +100.
Track your scores internally over time and, if possible, compare your scores to averages in your industry or direct competitors. For example, you can use benchmarks like the one below; a breakdown of NPS scores in different sectors:
Usually, if your company has more promoters than detractors, it’s good news. But, a really encouraging NPS score would be above 50.
NPS is still only one metric, though. It's best to use it as a guide to dive deeper into performance. Don’t get hung up on the numbers like “we have an average NPS of 70 percent”.
Also, use qualitative customer feedback as part of your customer service KPIs to help you improve NPS.
The CRR of a specific period is the percentage of customers you retained from the beginning of the period to the end. This excludes all customers you acquired within that period.
To measure Customer Retention Rate (CRR), you will need three key numbers:
CRR can be calculated by taking customers at the end of the period minus new customers divided by customers at the beginning of the period multiplied by 100%.
The closer this customer service KPI is to 100 percent, the better.
Ensure you are retaining customers through multiple periods and cultivate customer loyalty.
NRR measures your revenue at the end of a specific period from existing customers (including upgrades) after all churn and downgrades have been accounted for.
NRR is calculated by taking revenue plus upsells plus cross-sells minus downgrades minus cancellations divided by revenue multiplied by 100%.
You can track this metric both monthly and annually.
Generally, if NRR is higher than 100 percent, it means your business more than makes up for customer churn by acquiring new revenue from existing customers. If it’s less than 100 percent, then you’re losing business.
For reference, the median net retention of publicly traded software companies was 104.0 percent in 2018.
Let's continue this customer service KPIs list...
GRR shows you what percentage of revenue you’ve managed to keep from existing customers. That's without counting any additional revenue from upsells and cross-sells.
GRR is the revenue at the beginning of a period minus the lost revenue from churn in that period, divided by the initial revenue multiplied by 100%.
The same calculations apply to the annual GRR or comparing GRR between the same month year over year, as described for NRR.
Your GRR can go up to 100 percent, meaning you retain all customers and there are no downgrades in a given period.
Conversion rate shows the percentage of users completing a desired action such as booking a demo or purchasing a product.
Addressing CR can save you big time when it comes to paid advertising. It will help you discover your ideal customers and this will translate into the ability to further refine your marketing.
The conversion rate is calculated by taking the number of sales divided by the number of visits multiplied by 100.
Say an eCommerce site receives 200,000 visits in October. During that month, 4,000 users purchased online. Then, the conversion rate is: 4000/200000 * 100 = 2%.
Pro tip: If your conversion rate seems low or not reaching your marks, check out these 7 effective ways to increase conversion rates.
Conversion rate is one of the most popular customer service KPIs.
Also called “mean time to resolve (MTTR)", time-to-resolution (TTR) helps companies track the average time it takes to solve customer issues.
TTR is normally measured in hours or days, depending on the nature of the business. It takes into account the handling time elapsed from the moment a query comes in, to the time it gets resolved and closed.
Customer support teams are tasked with keeping TTRs short because that corresponds to better customer experiences.
MTTR is all times to resolution divided by the number of cases resolved.
Thankfully, you don't have to track this manually. With customer support software, time to resolution per agent is tracked automatically, among other customer service metrics.
This will help you see whether there are some customer service agents that take longer than others. Then you can dig deeper to see whether these support agents need more training or if they happen to take over the more complex customer issues.
Pro tip: creating a customer service knowledge base will free up agents and improve TTR.
First call resolution (FCR) refers to the number of times that an agent was able to resolve an issue on the very first call. Or, if you have an omnichannel contact center, the very first interaction or “contact.”
The first call resolution rate is the number of customers who had their issue resolved in one interaction divided by the number of customers who called in, multiplied by 100%.
Your customer service teams can internally decide on the nuances of calculating this rate, like whether abandoned or escalated calls should count. Or, what is the period of time that should pass before you count a call in your FCR. Once you decide on the exact definition, make sure it stays consistent over time.
The higher the FCR the better. Thirty-three percent of consumers (the biggest group) indicate that resolving their issues in one interaction is the most important part of a good customer experience.
One way to get data on first call resolution is through customer surveys. Customers can tell you directly whether their issue was resolved and after how many interactions.
You can also use tracking capabilities in your technology solutions such as customer support analytics or repeat call trackers.
Here's some customer service KPIs you've probably heard of.
Customer satisfaction reflects the level at which a customer is satisfied with a product, service, or experience.
Creating new customers costs at least 5 times more than retaining existing ones. This means a satisfied customer saves you money.
To obtain a customer satisfaction score means creating CSAT surveys. Effective surveys contain an average number of 5 to 10 questions relating to customer experience, service delivery, and measure overall satisfaction.
Customer satisfaction can be calculated by taking the number of positive responses and dividing by the total number of responses.
For example, if 85 of your 100 responses have a rating of 4 or 5 out of 5, your CSAT score would be 85.
To administer an effective CSAT survey, research the best survey questions to ask customers.
Monitoring your social media means observing social media platforms for brand mentions, competitors, or general industry trends.
Examples of social media monitoring can entail:
Pro tip: You can even use social media for customer service.
The engagement of customers start from the first touchpoint and incorporates all interactions, including the time customers spend with your brand and the actions they take throughout their journey.
These engagement metrics measure service accessibility and the quality of customer experience. For example, activation rate is triggered when a visitor takes a specific action and becomes an active user.
Activation rate can be calculated by taking the number of user sessions divided by the number of activities completed by users.
To do this correctly, try the following:
Pro tip: adding live chat software can measure customer engagement, the total number of chats, and top-performing agents.

What are active users? They're users interacting with your business within a specific period. Active users give a clue to the success of your customer service approach.
As this is a broad definition, it may be more practical to break it down, considering every important point on the customer journey.
Here's a checklist you can use:
Daily, weekly, and monthly active users indicate who is actively using your product or service in a given time period.
And now onto our final metric of customer service KPIs.
The conversation abandonment rate shows abandoned interactions across multiple platforms. These abandonments provide invaluable insights into customer behavior.
Segment customer conversation by channels and consider whether they are text-based or voice-based.
Segmenting text-based conversations on the basis of channel helps you get insights like number of customer requests per channel or how many agents are needed to handle a particular channel and meet KPI and SLA requirements.
Conversion abandonment rate can be calculated by taking the total number of completed transactions divided by the number of initiated checkouts, subtracting it from 1, and multiplying it by 100.
Calculating voice-based customer conversations helps you analyze:
It’s useful to know the formulas and definitions of KPIs for customer service to help you measure customer service success. But, remember to evaluate each metric both by itself and in relation to other relevant metrics.
At the end of the day, customers expect a great experience. Keeping a keen eye on customer service KPIs will help you see what works and what can be improved.
