In a call center, tracking the right performance metrics is essential for boosting productivity, maintaining agent engagement, and delivering a standout contact center experience.
But without the right tools, metrics don’t always accurately capture the full picture.
By focusing on both on-call and off-call activities, workforce management and QA tools provide valuable insights that go beyond the basics, helping you optimize workflows, support agents, and enhance customer satisfaction.
In this guide, we’ll break down the key inbound call center metrics, why they matter, and how to measure them with the right tools to transform your operations.
Manual vs. Tool-Based Metric Tracking
Whether your agents are on-site or working remotely, tracking call center metrics is essential for understanding performance, improving workflows, and ensuring agents stay productive. But how you track these metrics can make all the difference.
- Manual Tracking: Relies on spreadsheets, call logs, and agent feedback, making the process time-consuming and prone to errors. Managers often spend hours calculating metrics like Average Handle Time (AHT) after the fact, missing opportunities to make real-time improvements.
- Tool-Based Tracking: Automates data collection and provides real-time insights. Workforce management tools like QA monitoring software tracks AHT automatically, flag inconsistencies, and send performance alerts—helping you spot trends and make adjustments as needed
Let’s examine 15 essential call center metrics and how QA workforce management tools can streamline the process.
Key Inbound Call Center Metrics
Efficiency Metrics
Here’s a closer look at two critical efficiency metrics and how the right tools can make a difference.
Average Wait Time (AWT)
- What it is: The average time customers spend on hold before speaking to an agent.
- Why it matters: No one likes to wait, and long hold times are one of the quickest ways to frustrate customers and damage their perception of your service. A lower AWT not only improves the customer experience but also reflects efficient call routing, well-balanced staffing, and streamlined workflows.
Call Abandonment Rate (CAR)
- What it is: The percentage of calls customers hang up before speaking to an agent.
- Why it matters: A high CAR often signals customer frustration, which can lead to lost business and harm brand loyalty. When customers give up before getting help, it’s a clear sign that wait times, call routing, or staffing levels need attention.
How Workforce Management & QA Tools Help
Workforce management and QA tools provide visibility into how agents spend their time on off-call tasks, such as after-call work or administrative duties, which directly impacts efficiency metrics like AWT and CAR.
When agents are tied up with lengthy post-call tasks, fewer are available to take new calls, leading to longer hold times and higher abandonment rates. These tools help you streamline workflows to boost agent availability by identifying bottlenecks, like excessive documentation or manual processes.
Resolution Metrics
Resolution metrics help measure how effectively your call center addresses customer issues and keeps interactions productive. These metrics directly impact customer satisfaction, call volume, and overall agent performance.
First Call Resolution (FCR)
- What it is: The percentage of customer issues resolved during the first call, without requiring follow-ups or transfers.
- Why it matters: A high FCR means your agents can solve problems efficiently, which leads to happier customers and lower overall call volume. Customers expect fast, effective service, and resolving issues on the first call builds trust, reduces repeat interactions, and improves operational efficiency.
Average Handle Time (AHT)
- What it is: The average amount of time an agent spends on a call, including after-call tasks such as updating records and sending follow-up emails.
- Why it matters: Balancing AHT ensures that agents handle calls efficiently without rushing customers or compromising service quality. While shorter calls may seem ideal, a low AHT shouldn’t come at the expense of thorough issue resolution. The goal is to maintain both speed and quality.
How Workforce Management & QA Tools Help
Call center tools help you identify opportunities to simplify workflows by tracking the time your agents spend on post-call tasks and spotting where things slow them down.
If tasks like logging notes or sending follow-up emails are taking longer than they should, it could mean your agents need better tools, clearer processes, or a bit of extra training. These insights let you provide the right support to boost FCR and cut down on follow-ups.
You can also use productivity data to play to your agents' strengths, assigning complex issues to agents who thrive on problem-solving and ensuring they have the time and space to get it right the first time.
With balanced workloads, you can reduce AHT without making your team feel rushed, keeping productivity high and customers happy.
Customer Satisfaction Metrics
Customer satisfaction metrics provide direct feedback on how well your call center meets customer expectations. These metrics are essential for building loyalty, improving the overall contact center experience, and strengthening your brand reputation.
Customer Satisfaction Score (CSAT)
- What it is: A measure of customer satisfaction with their interaction, typically collected through post-call surveys.
- Why it matters: High CSAT scores indicate that customers feel valued and their issues have been resolved effectively. Positive customer experiences foster loyalty and drive repeat business, while low CSAT scores highlight areas where service improvements are needed.
Net Promoter Score (NPS)
- What it is: A measure of how likely customers are to recommend your service to others, typically asked as a simple post-interaction survey question: “On a scale of 0 to 10, how likely are you to recommend us?”
- Why it matters: NPS provides an overall indicator of customer satisfaction and brand perception. A higher NPS shows that customers trust and value your service, which can lead to referrals and long-term growth. A low NPS, on the other hand, can signal deeper service issues that need immediate attention.
How Workforce Management & QA Tools Help
Workforce management tools may not track survey feedback, but they ensure your agents have the time and support to deliver high-quality service. Monitoring workloads and off-call tasks like after-call work can prevent agents from feeling rushed, leading to more meaningful customer interactions.
When agents have the space to focus on customers instead of juggling tasks, you’ll see improvements in CSAT and a stronger NPS, building loyalty and enhancing your brand’s reputation.
Productivity Metrics
Productivity metrics measure how efficiently your agents handle tasks and maintain responsiveness throughout the day. These metrics ensure your team can handle call volumes without sacrificing service quality or agent well-being.
Average After-Call Work Time
- What it is: The average time an agent spends completing follow-up tasks after a call, such as logging details, updating records, or sending follow-up emails.
- Why it matters: Lower after-call work times free up agents to handle more calls, improving overall productivity and reducing customer wait times. However, if after-call work is rushed, critical details may be missed, affecting call resolution and customer satisfaction.
Service Level
- What it is: The percentage of calls answered within a specific time frame (e.g., 80% of calls answered within 30 seconds).
- Why it matters: High service levels indicate a responsive, well-staffed contact center and contribute to positive brand perception. On the other hand, low service levels can lead to longer wait times, customer frustration, and potential churn.
How Workforce Management & QA Tools Help
Workforce management tools track how long your agents spend on post-call work, directly impacting productivity metrics like ACW and Service Level. If agents spend too much time documenting interactions, introducing automation or pre-filled forms can help reduce ACW, freeing agents to handle more calls and improving overall responsiveness.
These tools also provide insights into task-related productivity trends, helping you ensure agents are available to meet service-level targets during high-volume periods. If you're figuring out how to monitor employees working from home, these tools give you the same visibility into remote teams, allowing you to spot performance trends and optimize workloads to keep service levels consistent.
Agent Performance Metrics
Agent performance metrics provide insights into how well your team adheres to schedules and remains engaged over time. Tracking these metrics helps maintain adequate staffing, reduce operational disruptions, and foster a more stable, productive team.
Agent Schedule Adherence
- What it is: A measure of how closely agents follow their assigned schedules, including start times, breaks, and after-call work.
- Why it matters: High adherence ensures that the right number of agents are available to handle incoming calls, preventing gaps in coverage that can lead to longer wait times and frustrated customers. Poor adherence can create bottlenecks during peak times and increase the workload for other team members, potentially causing burnout.
Agent Attrition Rate
- What it is: The percentage of agents who leave the organization within a specific time frame.
- Why it matters: High attrition rates increase recruiting and training costs and can negatively impact team morale. When experienced agents leave, it creates knowledge gaps and increases the burden on remaining team members, potentially affecting customer service quality.
How Workforce Management & QA Tools Help
Workforce management tools track real-time agent activity, showing when agents are active, on break, or logged out—key data for measuring Schedule Adherence. This visibility helps you spot adherence trends and address scheduling issues before they disrupt coverage or lead to longer wait times. By making proactive adjustments, you can keep your team aligned and ensure customers aren’t left waiting during peak times.
Tools like Insightful also reveal productivity patterns that can indicate early signs of disengagement or burnout, which ties directly to Agent Attrition Rate. If you notice agents taking longer idle periods or missing key tasks, you can step in with personalized support or workload adjustments to re-engage your team and foster a more productive, balanced work environment.
