The right metrics create accountability across your organization. They give agents clear targets to work toward and provide managers with objective criteria for evaluating performance. When everyone understands how success is measured, your entire operation becomes more focused and efficient.
Now, let’s jump into the 20 most essential metrics to track in your call center.
Customer Experience Metrics
Customer experience metrics examine how well customers perceive their experiences when calling into your call center. These measures affect customer retention and loyalty. Higher customer experience leads to longer customer life spans and more positive word of mouth advertising.
1. Customer Satisfaction Score (CSAT)
Customer Satisfaction Score (CSAT) measures how satisfied customers are with a specific interaction or service experience. It's typically collected through post-interaction surveys asking customers to rate their satisfaction on a scale.
- Ideal score: 80% or higher is considered good, while 90% or above indicates excellent customer satisfaction.
- Why it matters: High CSAT scores correlate with customer retention and repeat business. Low scores indicate problems with agent training or processes that need immediate attention.
- How to improve it: Train agents on active listening and empathy. Gather feedback immediately after service calls to identify patterns in customer dissatisfaction.
2. Net Promoter Score (NPS)
Net Promoter Score (NPS) measures customer loyalty by asking how likely customers are to recommend your company to others. Respondents rate their likelihood on a scale from 0 to 10, then are categorized as promoters, passives, or detractors.
- Ideal score: Above 0 is acceptable, above 50 is excellent, and scores above 70 are considered world-class.
- Why it matters: NPS predicts business growth through word-of-mouth referrals and provides a single metric to benchmark against competitors.
- How to improve it: Follow up with detractors to understand their concerns and address specific pain points. Focus on creating consistent positive experiences across all customer touchpoints.
3. Customer Effort Score (CES)
Customer Effort Score (CES) measures how much effort a customer had to expend to get their issue resolved. Lower effort typically leads to higher loyalty, as customers prefer quick and easy problem resolution.
- Ideal score: 5 or higher on a 7-point scale, where 7 represents "very easy" and 1 represents "very difficult."
- Why it matters: Customers who experience low-effort interactions are more likely to remain loyal and make repeat purchases. High-effort experiences drive customers to competitors.
- How to improve it: Improve self-service options and give agents better tools to resolve issues quickly. Minimize transfers between departments and eliminate unnecessary verification steps.
4. First Contact Resolution (FCR)
First Contact Resolution (FCR) measures the percentage of calls (or contacts) resolved during the initial interaction without follow-up. It's one of the most important indicators of call center efficiency.
- Ideal score: 70% to 75% is average, while 80% or higher indicates excellent performance.
- Why it matters: High FCR reduces operational costs by eliminating repeat contacts and improves customer satisfaction by solving problems quickly.
- How to improve it: Invest in comprehensive call center training so representatives can handle a wider range of issues. Provide agents with access to knowledge bases and decision-making authority to resolve problems on the first call.

Service Level & Responsiveness Metrics
Service level and responsiveness metrics track how quickly your call center answers customer calls. These measures directly affect customer satisfaction and call abandonment rates. Fast, consistent response times create positive customer experiences and reduce the number of callers who hang up before reaching an agent.
5. Average Speed of Answer (ASA)
Average Speed of Answer (ASA) measures the average time it takes for call center agents to answer incoming calls. This metric tracks the seconds or minutes customers spend waiting before connecting with a live representative.
- Ideal score: 20 seconds or less is considered excellent, while 28 seconds is the industry average.
- Why it matters: Long wait times frustrate customers and increase call abandonment rates. Fast answer speeds improve customer satisfaction and create positive first impressions.
- How to improve it: Optimize agent scheduling to match peak hours. Consider implementing callback options for inbound calls during high-volume periods so customers don't have to wait on hold.
6. Service Level Rate
Service Level Rate measures the percentage of answered calls within a specific timeframe, typically expressed as a ratio like 80/20 (80% of customer calls answered within 20 seconds). This metric helps managers understand how consistently the team meets response time goals.
- Ideal score: 80% of calls answered within 20 seconds is the standard industry benchmark.
- Why it matters: Consistent service levels ensure customers receive reliable support experiences regardless of when they call. Meeting service level targets reduces customer frustration.
- How to improve it: Use real-time monitoring dashboards to identify when call queues are building and adjust staffing accordingly. Cross-train agents to handle multiple call types so you can redistribute workload during volume spikes.
7. Call Abandonment Rate
Call Abandonment Rate measures the percentage of callers who hang up before reaching an agent. High abandonment rates indicate customers are unwilling to wait for service and may take their business elsewhere.
- Ideal score: 5% to 8% is considered acceptable, while rates below 5% indicate excellent performance.
- Why it matters: Abandoned calls represent lost sales opportunities and frustrated customers who may switch to competitors.
- How to improve it: Reduce wait times through better staffing and scheduling practices. Offer callback options so customers can request a return call instead of waiting on hold.
Operational Efficiency Metrics
Operational efficiency metrics measure the performance of your call center over a specific time. These benchmarks reveal the peak periods with the highest call volume and define staffing needs. Managers then know how well your call center operates each day and can determine ways to optimize operations.
8. Call Arrival Rate
Call Arrival Rate measures the total number of calls your center receives during a specific time period. This metric helps predict staffing needs and identify patterns in customer contact behavior.
- Ideal score: There is no universal ideal score, as call volume varies by industry and business size. Focus on tracking trends to identify peak periods.
- Why it matters: Understanding call arrival patterns allows you to schedule the right number of agents for busy periods and avoid understaffing.
- How to improve it: Use historical data to predict volume patterns and adjust staffing levels. Implement self-service options like Interactive Voice Response (IVR) to handle simple requests.
9. Average Wait Time
Average Wait Time measures how long customers spend in the queue waiting for an agent to pick up their call. This differs from Average Speed of Answer by focusing on individual customer wait experiences.
- Ideal score: Under 1 minute is excellent, while 2 to 3 minutes is acceptable for most call centers.
- Why it matters: Wait time is one of the strongest predictors of customer satisfaction and directly influences whether customers abandon calls.
- How to improve it: Forecast call volume accurately and staff appropriately during peak periods. Implement virtual queuing or callback systems that let customers hold their place in line.
10. Average Handle Time (AHT)
Average Handle Time (AHT) measures the total time an agent spends on customer interactions, including talk time, hold time, and after-call work. This is one of the most commonly tracked call center efficiency metrics.
- Ideal score: 6 minutes or less is typical for most industries, though complex technical support may require longer times.
- Why it matters: Lower AHT means agents can help more customers per shift, reducing operational costs. However, rushing calls to improve AHT can hurt service quality.
- How to improve it: Provide agents with scripts and templates for common scenarios. Automate after-call documentation and simplify internal systems so agents spend less time on administrative tasks.
11. Average Talk Time
Average Talk Time measures how long agents spend actively speaking with customers, excluding hold time and after-call work. This metric isolates the conversation portion of customer interactions.
- Ideal score: 3 to 5 minutes is average for most call centers, though this varies based on call complexity and industry.
- Why it matters: Talk time reveals how efficiently agents communicate and resolve issues during active conversation. Unusually high talk times may indicate agents need better training.
- How to improve it: Train agents on effective communication techniques that get to the point quickly without sacrificing courtesy. Create standardized procedures for common issues.
12. After-Call Work (ACW)
After-Call Work (ACW) measures the time agents spend completing tasks after ending a call with a customer. This includes tasks like updating records, documenting issues, scheduling follow-ups, and processing orders.
- Ideal score: 30 to 90 seconds is typical, though complex cases may require more time for thorough documentation.
- Why it matters: Excessive after-call work reduces the number of calls agents can handle per shift and increases operational costs.
- How to improve it: Use process automation for repetitive data entry and pair it with templates for common documentation scenarios. Provide agents with streamlined CRM systems that require fewer clicks.
13. Cost Per Call (CPC)
Cost Per Call (CPC) measures the average cost of handling each customer interaction, including agent salaries, call center technology costs, facilities, and overhead. This metric helps managers understand the true financial impact of call center operations.
- Ideal score: $2.70 to $5.60 per call is average for most industries, though this varies significantly based on call complexity and business model.
- Why it matters: Understanding cost per call helps justify technology investments and identify opportunities to reduce expenses without sacrificing quality.
- How to improve it: Increase first contact resolution to eliminate costly repeat calls and implement self-service options for simple inquiries. Invest in agent training to reduce handle time.

Agent Performance Metrics
Agent performance metrics evaluate how well individual representatives handle their responsibilities and follow call center procedures. These measures help managers identify training needs, recognize top performers, and maintain consistent service quality across the team.
14. Schedule Adherence
Schedule Adherence measures how closely agents follow their assigned work schedules, including start times, breaks, and lunch periods. This metric tracks the percentage of time agents are available when they're supposed to be.
- Ideal score: 95% or higher indicates strong schedule compliance and reliable staffing coverage.
- Why it matters: Poor adherence creates staffing gaps that increase customer wait times and burden other agents who are following their schedules.
- How to improve it: Use workforce management software to send automated reminders about breaks and shifts. Address underlying causes like burnout or scheduling conflicts.
15. Agent Utilization Rate
Agent Utilization Rate measures the percentage of an agent's shift spent on productive work like handling calls, responding to emails, or completing after-call tasks. This excludes idle time between interactions.
- Ideal score: 85% to 90% is optimal, as 100% utilization leads to agent burnout and quality issues.
- Why it matters: Low utilization means you're paying agents for idle time, while excessively high utilization causes stress and performance problems.
- How to improve it: Balance call routing to distribute work evenly across agents. Adjust staffing levels to match actual demand patterns.
16. Agent Turnover Rate
Agent Turnover Rate measures the percentage of agents who leave your call center within a specific period, typically annually. High turnover disrupts operations and increases recruiting and training costs.
- Ideal score: 30% to 45% annually is average for call centers, though lower rates indicate better retention and workplace satisfaction.
- Why it matters: Replacing agents costs thousands of dollars in recruiting, hiring, and training expenses. High turnover also reduces service quality.
- How to improve it: Offer competitive compensation and clear career advancement paths. Improve work conditions by providing better tools and supportive call center management.
17. Quality Assurance (QA) Score
Quality Assurance Score measures agent performance based on call evaluations completed by supervisors or quality analysts. Using call center quality assurance best practices, evaluators review factors like accuracy and adherence to company standards.
- Ideal score: 90% or higher indicates strong performance, though scoring criteria vary by company and industry.
- Why it matters: QA scores identify training gaps and ensure agents consistently deliver high-quality service that meets company standards and customer expectations.
- How to improve it: Provide specific feedback from QA evaluations and create targeted coaching plans for agents with low scores. Use call recordings to demonstrate best practices.
