Eglė Račkauskaitė at Capacity explores the 14 most crucial contact centre KPIs to help you monitor performance and achieve your business objectives. You’ll also find 10 steps to help you implement a sustainable contact centre productivity strategy.
Contact centre KPIs measure how well and how fast your human and AI agents solve customer problems. However, most modern contact centres measure more than just speed and quality. And with AI agents, old KPIs often don’t cut it anymore.
For example, a 2024 March Market Study found that two-thirds of customers say they experience long wait times while dealing with customer service teams. But how do you measure these abstract goals, your call centre productivity, and the team’s efficiency?
Contact center key performance indicators (KPIs) are the measurable metrics used to track how well a contact center is performing against its goals.
They show how effectively agents resolve customer issues, how satisfied customers are with the service they receive, and how efficiently the operation runs day to day.
Keeping track of your contact center analytics helps you spot bottlenecks, improve service quality, control costs, and make staffing and call center training decisions based on data.
They’re typically grouped into three categories:
Below, we go over these in more detail.
The most important customer experience KPIs cover the speed, quality, and accuracy of your support. For example, CSAT, NPS, and CES measure how customers perceive your service.
Let’s go over these and other important CX KPIs, along with their formulas and the ways they improve your customer service.
Contact center CSAT measures how satisfied customers are with a specific interaction, product, or service, usually captured through a short post-contact survey asking them to rate their experience.
You might send a message or ask after the call to rate their experience from 1 to 5. It’s one of the most direct ways to gauge whether a customer left an interaction happy.
Example:
Improving CSAT in a contact center means more customers are walking away from interactions feeling their needs were met, which strengthens trust and loyalty over time.
NPS measures overall customer loyalty by asking how likely someone is to recommend your company to a friend or colleague, typically on a 0–10 scale. Respondents are grouped into promoters (9–10), passives (7–8), and detractors (0–6).
Example:
A higher NPS indicates more customers are enthusiastic advocates rather than critics, which signals stronger relationships and a better long-term experience.
CES is a contact center KPI that measures how much effort a customer had to put in to get their issue resolved, usually by asking them to rate the ease of the interaction on a defined scale. The idea is that low-effort experiences drive loyalty more reliably than “delightful” ones.
Example: Suppose you collect 10 responses with these effort scores:
Lowering customer effort means people get help faster and with less frustration, which removes friction and makes the overall experience feel effortless.
FCR rate tracks the percentage of customer issues resolved during the first interaction, without the need for a callback, follow-up, or escalation.
Example:
Raising FCR means customers get complete answers the first time they reach out, sparing them repeat contacts and the irritation of explaining their problem more than once.
Average wait time measures how long customers wait in the queue before connecting with an agent. It’s a key driver of first impressions, since long waits frustrate customers before the conversation even begins.
Example:
Reducing average wait time gets customers to help sooner, easing frustration and setting a positive tone for the rest of the interaction.
You should track agent performance metrics, like average handle time, agent occupancy rate, quality assurance score, and schedule adherence. Let’s go over how to set up and track these KPIs in practice.
AHT measures the average total time an agent spends on a customer interaction, including talk time, hold time, and after-call work, like logging notes or updating records.
Example:
Optimizing AHT helps agents resolve issues efficiently without rushing, balancing speed with quality so they can handle more contacts without burning out.
The occupancy rate shows the percentage of an agent’s logged-in time spent handling contacts versus sitting idle waiting for the next one. It’s a useful gauge of how well the workload is distributed across the team.
Example:
Keeping occupancy in a healthy range ensures agents stay productive without being overloaded, which sustains performance and reduces the fatigue that comes from being constantly maxed out.
The QA score rates how well agents adhere to standards during interactions, covering things like communication, accuracy, compliance, and proper procedures. After reviewing recorded or live contacts against a scorecard, evaluators assign these scores.
Example:
If your evaluation rubric has a total of 60 possible points across all criteria, and on a reviewed call, an agent earns 54 of them, then the formula goes like this:
Improving QA scores means agents consistently deliver accurate, professional, on-policy service, which raises the overall standard of work and pinpoints where coaching is needed.
Schedule adherence measures how closely agents follow their assigned schedules, including shift start times, breaks, lunches, and availability windows. It reflects reliability and helps ensure the right number of agents are staffed at the right times.
Example:
If your agent works an 8-hour shift (480 minutes), and over that shift they work as scheduled for 456 minutes, then the formula goes like:
Strengthening adherence keeps staffing aligned with demand, so agents are available when they’re needed most, and the team’s performance stays predictable and dependable.
Contact center efficiency shows up in KPIs like service level, average speed of answer (ASA), abandonment rate, cost per contact, and deflection rate. Let’s see the formulas and how they actually improve your contact center.
Service level measures the percentage of contacts answered within a defined target time, often expressed as a goal like “80% of calls answered within 20 seconds.” It’s a benchmark for how reliably the center meets its responsiveness commitments.
Example:
If your team answers 1,000 contacts per day, and 850 of them are answered within a 20-second window, the formula goes like:
Hitting service level targets means staffing and routing are well matched to demand, allowing the center to handle volume smoothly without bottlenecks or excess idle capacity.
ASA measures the average time customers spend waiting in the queue before an agent picks up.
Example:
If in an hour you answer 120 contacts, and the combined time all those customers spent waiting in the queue totals 1,800 seconds, then the formula goes like:
Lowering ASA signals that resources are being used effectively to clear the queue faster, which increases throughput and lets the center serve more customers in less time.
Abandonment rate tracks the percentage of customers who leave the queue before reaching an agent, usually because they’ve waited too long. High abandonment often points to understaffing or inefficient routing.
Example:
Over a day you receive 1,500 incoming contacts, and 90 of those customers hang up before being answered, so your abandonment rate would be:
Reducing abandonment means fewer wasted contacts and callbacks clogging the system, so capacity is spent resolving issues the first time rather than absorbing repeat attempts.
Cost per contact measures the average total cost of handling a single customer interaction, factoring in labour, technology, and overhead. It’s a foundational metric for understanding the financial efficiency of the operation.
Example:
Driving down cost per contact without sacrificing quality shows the center is getting more value from its resources, freeing up budget and improving the overall return on every interaction.
Deflection rate measures the percentage of contacts resolved through self-service or automated channels (like knowledge bases, chatbots, or IVR) before they ever reach a live agent. It indicates how well lower-cost channels absorb demand.
Good KPI benchmarks show how well your contact center and teams are performing compared to the industry standard.
It’s something to strive for, but every company is different, and the benchmarks are more like a guide, not a standard for every contact center. With that being said, here are industry benchmarks for each KPI we listed above.
Raising deflection rate shifts routine inquiries away from agents, letting them focus on complex issues while the center handles higher volumes at a lower cost per interaction.
| KPI | Industry Benchmark | Notes |
|---|---|---|
| CSAT | Good: 75-84%; world- class: 85%+ | Varies by call type and industry; few businesses hit world-class |
| NPS | Global average +42; leading centres +30 to +50 | Tech and services tend to score higher than telecom or hospitality |
| CES | 5.3 out of 7 | Keep “difficult” responses below 10–15% of resolved interactions |
| FCR | Good: 70-79% | Dropping below 70% often signals a need for better knowledge access |
| Average Wait Time (ASA) | Global average – 28 sec; excellent: ≤20 sec | 20 seconds or less is excellent; 28 seconds is average |
| AHT | ~3–7 min | Varies by call type and industry; don’t sacrifice quality for speed |
| Occupancy Rate | 75–85% | Pushing above 85% can burn out your team and hurt other KPIs |
| QA Score | 80-90% | No industry standard — best to define your own rubric |
| Schedule Adherence | ~85%+ | No solid standard; depends on your team’s operating rhythm |
| Service Level | 80/20 | Most businesses target 80% of calls answered within 20 seconds |
| ASA | ~28 sec | Lower is better, but balance against staffing costs |
| Abandonment Rate | <5% good; 5–8% acceptable | 5–8% is acceptable; below 5% is excellent |
| Cost Per Contact | Global baseline ~$6–7 | Regulated industries like finance, SaaS, and healthcare often spend 3x to 10x+ more |
| Deflection Rate | ~25–90% | Varies by channel — chatbot deflection often outperforms voice and SMS |
AI improves contact center metrics and KPIs by lowering average handle time, giving your customers convenient self-service options, and helping your agents in real-time. Let’s go over the main AI benefits for contact center KPIs in more detail
Real-time agent assist tools listen to or read a live conversation and surface help to the agent in the moment, without the customer ever knowing.
It lowers AHT by cutting out search time, hold time, and after-call work. AI can also auto-summarize the interaction and draft the wrap-up notes when the call ends.
It lifts FCR because agents have the full context and the correct answer on the first attempt, so fewer issues get escalated, transferred, or left unresolved.
QA used to evaluate just 1-3% of customer interactions, which isn’t enough to make any conclusion about how your team is doing.
AI-powered call centre quality monitoring and assurance change the math by evaluating 100% of interactions against a defined scorecard automatically.
Using speech and text analytics, conversational intelligence technology checks whether agents followed procedures, hit compliance requirements, showed empathy, and resolved the issue, then assigns consistent scores across every contact.
AI sentiment analysis can infer satisfaction from every interaction by reading tone, word choice, and frustration cues in the conversation itself, which can help predict CSAT score for 100% of contacts rather than the few who respond to surveys.
On the deflection rate side, AI chatbots, virtual agents, and intelligent IVR resolve password resets, order status, billing questions, and other routine questions through self-service, before they ever reach a live agent.
To build a contact centre KPI framework for your business, you first need to know what your contact centre is trying to achieve.
For some businesses, speed is of utmost importance, while others focus on excellent quality and first call resolutions. You also don’t need to track all of the KPIs that exist.
They might tell you nothing about how your business is doing and only add more to your busy schedule. Let’s see 10 steps to start building an effective KPI framework that brings results.
Before choosing any KPI, define what your contact centre is trying to achieve, whether it’s to reduce churn, control costs, improve loyalty, or support a product launch.
Every KPI you track should ladder up to one of these goals. If a metric doesn’t connect to retention, revenue, or cost, drop it.
Avoid optimizing one dimension at the expense of others. Pick a handful of KPIs spanning customer experience like CSAT and FCR, agent performance like AHT and QA score, and operational efficiency like service level and cost per contact. Tracking AHT alone, for instance, can push agents to rush calls and quietly damage FCR and CSAT.
Choose a small set of primary KPIs that drive decisions, and treat the rest as diagnostic measures you consult only when a primary KPI moves.
Document the exact formula, data source, and what counts and what doesn’t. For example, whether after-call work is included in AHT, or what window qualifies as “first contact” for FCR.
Use industry benchmarks as a sanity check, but always go back to your current performance and operational realities. A regulated financial services center will rightly prioritize FCR and compliance over raw speed.
Technical or multi-party issues will have lower FCR and longer AHT than simple billing questions, and chat behaves differently from voice. Set ranges by channel and contact type so targets stay fair and actionable.
Every primary KPI needs an owner accountable for it, and the numbers should be visible to the people who influence them.
Supervisors and agents should be able to access real-time dashboards for supervisors and agents, while leadership should get summary views.
Match the review frequency to how fast each metric moves: daily for volume, AHT, and ASA; weekly for FCR trends, occupancy, and abandonment patterns; monthly for CSAT, NPS, and cost per contact. Set threshold alerts so managers can react to SLA risks before they become breaches.
When a metric slips, figure out why that happened. A falling FCR might trace to a knowledge gap, a confusing script, or a system outage.
KPIs aren’t set in stone. As AI absorbs routine volume, customer expectations shift, or business priorities change, retire metrics that no longer drive decisions and add ones that do. Review the framework itself at least once or twice a year, not just the numbers inside it.
Measuring KPIs is the first step to knowing where your business stands and where it’s headed. But knowing isn’t enough. As standards rise across industries, traditional methods don’t always get you there.
That’s where AI and smart automation come in. They can help your contact center reduce average handle time, increase first contact resolution, improve customer satisfaction scores, and lower operational costs.
The savings are significant: a live interaction costs roughly $7 and can easily reach $13.50, compared to just $0.50 to $2.00 with AI self-service.
