Call Centre KPIs
Call centre KPIs — Key Performance Indicators — are the metrics that define the targets a contact centre, its teams and its agents are expected to meet in order to achieve the wider business objectives.
In plain terms, a KPI is a measure that tells you whether your contact centre is performing the way it should.
Because contact centres generate an enormous amount of data, there are literally hundreds of possible metrics — but only a handful genuinely matter for any given operation.
The skill isn't measuring more; it's choosing the right KPIs, grouping them sensibly, and making sure each one is tied to a business outcome rather than tracked for its own sake.
This guide explains what KPIs are, how to choose them, and then walks through the key contact centre KPIs — grouped into efficiency, service and quality & experience — with a link to a full definition for each.
What they are
The metrics that measure how well a contact centre, team or agent is performing against its targets and business objectives.
Why they matter
The right KPIs focus effort, drive the right behaviours and connect day-to-day operations to customer and business outcomes.

What are Call Centre KPIs?
In plain English
A Key Performance Indicator (KPI) is a metric that tells you whether your contact centre is meeting its targets.
KPIs define the standards an agent, team, manager or whole operation is expected to reach so the business can achieve its objectives — whether that's answering calls quickly, resolving issues first time, or keeping customers satisfied.
Contact centres are never short of data; the challenge is picking the small set of metrics that actually reflect what matters and acting on them consistently.
KPIs generally fall into two broad types. Quantitative KPIs measure volume and efficiency — things like the number of calls, average handling time and occupancy.
Qualitative KPIs measure how well the work is done — quality scores, customer satisfaction and Net Promoter Score. A healthy scorecard usually blends both, so you're never chasing speed at the expense of the customer experience.
What they are
A deliberately small set of measures — efficiency, service and quality — that together show whether the contact centre is performing and where to focus.
What they aren't
They're not a dashboard of everything you can possibly count. Tracking hundreds of metrics without a purpose creates noise, not insight.
How to Choose KPIs
Choosing KPIs is less about the metrics themselves and more about what you're trying to achieve. Start with the business objective, then work backwards to the handful of measures that tell you whether you're getting there.
Start with strategy
Decide what the contact centre is there to deliver — speed, resolution, experience, cost — and let that shape which KPIs matter.
Balance the categories
Pick a mix across efficiency, service and quality so no single number can be gamed at the expense of the others.
Keep the set small
A few well-chosen KPIs beat a wall of dashboards. If a metric doesn't change a decision, it probably isn't a KPI.
Review and adjust
As the business changes, so should the KPIs. Revisit them regularly to make sure they still drive the right behaviours.
💡 What you need to measure KPIs
To measure KPIs effectively you need a contact centre technology platform to capture the data. Modern cloud contact centre solutions make this cost-effective, but without a platform of some kind you simply won't have the reliable data needed to track KPIs.
Most metrics are then reported by hour, day, week, month or year depending on what they measure.
Efficiency KPIs
Efficiency KPIs measure how productively the contact centre uses its people and time. They're the backbone of workforce management and capacity planning — but they should always be balanced against service and quality.
Handling and productivity
- Average Handling Time (AHT): the average time an agent spends handling a contact end-to-end — talk time, hold time and after-call work combined. A core planning metric, but lower isn't automatically better if it hurts resolution.
- Occupancy: the proportion of an agent's logged-in time spent actively handling contacts versus waiting for the next one. Very high occupancy signals under-staffing and burnout risk.
Scheduling and time management
- Shrinkage: the percentage of paid time agents are not available to handle contacts — breaks, meetings, training, leave and other off-phone activities. Essential for accurate staffing.
- Adherence: how closely agents stick to their rostered schedule — being in the right place, doing the right activity, at the right time.
- Conformance: whether agents work the total amount of scheduled time they're rostered for, regardless of exactly when. A close cousin of adherence, focused on total hours rather than timing.
Service KPIs
Service KPIs measure the experience of getting through to your contact centre — how accessible you are and how many customers you reach before they give up.
Accessibility
- Service Level: the percentage of contacts answered within a target time — for example, 80% of calls answered in 20 seconds. The most widely used measure of contact centre accessibility, and a headline KPI in almost every operation.
- Average Speed of Answer (ASA): the average time callers wait in the queue before an agent answers — a direct measure of how quickly you're getting to customers.
- Abandonment Rate: the percentage of callers who hang up before reaching an agent. A high abandonment rate is an early warning that customers are waiting too long, and it's closely linked to both service level and speed of answer.
💡 Service metrics work as a set
Service level, abandonment rate and average speed of answer move together — improve one and you usually improve the others. Read them side by side rather than in isolation, and always in the context of your staffing and forecast.
Quality & Experience KPIs
Quality and experience KPIs measure how well the work is done and how customers feel about it. These are the metrics that stop an efficiency-only scorecard from quietly damaging the customer experience.
Resolution and quality
- First Contact Resolution (FCR): the percentage of contacts resolved on the first interaction, with no need for the customer to get back in touch. One of the strongest predictors of both satisfaction and cost.
- Quality Assurance (QA): the structured evaluation of contacts against a scorecard to check accuracy, compliance and the quality of the customer interaction. It turns "good service" into something you can measure and coach.
Customer sentiment
- CSAT (Customer Satisfaction): a direct measure of how satisfied customers are with a specific interaction, usually captured through a short post-contact survey.
- NPS (Net Promoter Score): a measure of loyalty based on how likely customers are to recommend you, giving a relationship-level view rather than a single-interaction one.
- CES (Customer Effort Score): how easy it was for the customer to get their issue resolved. Low effort is strongly linked to loyalty, making CES a valuable complement to CSAT and NPS.
💡 Build the customer into your scorecard
Efficiency KPIs are easy to measure, so they tend to dominate. Deliberately weighting quality and experience KPIs — FCR, QA, CSAT, NPS and CES — keeps the customer visible in your numbers, not just your intentions.
Benchmarking & the Industry
KPIs tell you how you're performing. Benchmarks tell you how that compares with everyone else.
In Australia, ACXPA independently measures contact centre performance through the Australian Call Centre Rankings — real customer interactions, scored against the Contact Centre CX Standards.
Accessibility metrics
The rankings capture accessibility — answerability and wait times — showing how easily customers actually get through, sector by sector. It's the independent view your own service level and abandonment figures can't give you.
Soft skills (Agent Mastery)
Hard metrics miss how an interaction felt. The CX Standards score Agent Mastery — listening, helping and respecting the customer — so soft skills are measured, not assumed.
💡 Measuring agent performance
Don't reduce an agent to a single number. ACXPA's Call Centre Performance Matrix plots output against quality, so you coach the whole picture — not just the fastest or the busiest.

⚠️ Benchmarks are context, not targets
It's tempting to chase a leaderboard position or copy someone else's numbers. Resist it.
What matters is what you want to deliver for your customers, and the balance of cost and outcome that's right for your business. Use a benchmark to interpret your own KPIs — not as a target to adopt blindly.
Avoiding Over-Measuring
The most common KPI mistake isn't measuring the wrong things — it's measuring too many things, or measuring in a way that drives the wrong behaviour.
📉 Don't measure everything
Just because you can track a metric doesn't mean you should. Hundreds of KPIs create noise, dilute focus and make it harder to see what actually matters.
⚖️ Watch for gaming
Any single metric in isolation can be gamed. Balancing efficiency, service and quality stops agents optimising one number at the expense of the customer.
🎯 Align to strategy
Every KPI should trace back to a business objective. If you can't explain why a metric matters, it probably shouldn't be a KPI.
⚠️ KPIs drive behaviour — choose carefully
People manage to what's measured. Over-weight average handling time and agents rush customers; over-weight occupancy and you burn people out. Because KPIs shape behaviour so directly, the metrics you choose — and how you balance them — matter as much as the targets you set.
The goal is a small, balanced set of KPIs that reflects your strategy and drives the outcomes you actually want.
Frequently Asked Questions About Call Centre KPIs
What are call centre KPIs?
Call centre KPIs (Key Performance Indicators) are the metrics that define the targets a contact centre, its teams and its agents are expected to meet to achieve business objectives. They typically fall into efficiency measures (like average handling time and occupancy), service measures (like service level and abandonment rate) and quality and experience measures (like first contact resolution, CSAT and NPS).
What are the most important call centre KPIs?
There's no universal list — it depends on your strategy — but a balanced scorecard usually includes a service metric (service level or abandonment rate), an efficiency metric (average handling time or occupancy) and an experience metric (first contact resolution, CSAT or NPS). The key is choosing a small set that spans efficiency, service and quality rather than focusing on one category.
How many KPIs should a call centre track?
Fewer than most teams think. While hundreds of metrics are available, a good scorecard focuses on a handful of KPIs that genuinely drive decisions — typically a balanced mix across efficiency, service and quality. Tracking too many metrics creates noise, dilutes focus and makes it harder to act on what matters.
What's the difference between a metric and a KPI?
Every KPI is a metric, but not every metric is a KPI. A metric is anything you can measure; a KPI is a metric you've chosen because it's tied to a business objective and used to manage performance. Contact centres capture many metrics, but only elevate a small number to KPIs that teams are actively managed against.
How are call centre KPIs measured?
KPIs are measured using a contact centre technology platform that captures call, agent and customer data. Cloud contact centre solutions make this cost-effective, but without a platform of some kind you can't reliably capture the data. Depending on the metric, KPIs are typically reported by hour, day, week, month or year.
What are efficiency, service and quality KPIs?
They're the three broad categories of contact centre KPIs. Efficiency KPIs (average handling time, occupancy, shrinkage, adherence, conformance) measure how productively time is used. Service KPIs (service level, average speed of answer, abandonment rate) measure accessibility. Quality and experience KPIs (first contact resolution, quality assurance, CSAT, NPS, customer effort score) measure how well the work is done and how customers feel about it.
Why is it a mistake to over-measure KPIs?
Because KPIs drive behaviour. Tracking too many metrics creates noise and dilutes focus, and over-weighting any single metric encourages people to optimise that number at the expense of the customer — for example, rushing calls to reduce handling time. A small, balanced set of KPIs aligned to strategy avoids these traps and keeps effort pointed at real outcomes.
Where to Next
Summary: Call Centre KPIs
Call centre KPIs are the metrics that define the targets a contact centre, its teams and its agents are expected to meet to achieve business objectives.
They group naturally into three categories. Efficiency KPIs — average handling time, occupancy, shrinkage, adherence and conformance — measure how productively time is used.
Service KPIs — service level, average speed of answer and abandonment rate — measure accessibility. Quality & experience KPIs — first contact resolution, quality assurance, CSAT, NPS and customer effort score — measure how well the work is done.
The real skill is choosing a small, balanced set that spans all three categories, ties back to your strategy, and avoids the trap of over-measuring.
Because KPIs drive behaviour, the metrics you pick — and how you weight them — matter as much as the targets you set.
