Understanding key performance indicators (KPIs) is crucial for optimizing call center operations. KPIs are specific metrics used to measure performance and assess how effectively a call center is achieving its objectives. By monitoring these KPIs, call center leaders can identify areas for improvement, enhance customer satisfaction, and boost overall efficiency.

In this guide, we’ll introduce the most important KPIs for call centers, explain how to measure them, and provide practical tips for using these metrics to drive success.

1. Average Handle Time (AHT)

Average Handle Time (AHT) is a fundamental KPI in call centers. It measures the average duration of a customer interaction, including hold time, talk time, and after-call work (ACW). Essentially, AHT helps assess the efficiency of your call center agents in handling customer inquiries.

A lower AHT indicates that calls are resolved quickly, but if it’s too low, it might suggest that agents are rushing through calls, potentially impacting customer satisfaction.

Why It Matters

AHT is crucial for both operational efficiency and customer experience. When AHT is optimized, it ensures that customers are not kept waiting and that agents are productive. However, it is important to balance speed with quality. For instance, if agents are too focused on reducing AHT, they might not fully address customer needs, leading to dissatisfaction.

How to Measure AHT

To calculate AHT, use the following formula:

AHT = (Total Talk Time + Total Hold Time + Total After-Call Work Time) / Total Number of Calls Handled

This formula provides the average time, in seconds or minutes, that an agent spends on each call. Monitoring AHT regularly allows you to identify trends and make necessary adjustments. Moreover, tracking AHT helps in planning training sessions and optimizing call handling procedures.

Best Practices for Measuring AHT

• Use Workforce Management (WFM) Tools: Tools like NICE IEX and Verint provide real-time data on AHT. These tools help identify patterns and training opportunities. For example, if AHT is consistently high, it might indicate a need for additional training.
• Automate Repetitive Tasks: Using CRM tools can reduce the time agents spend on manual tasks and after-call work, thereby lowering AHT. Automation tools can help streamline processes, allowing agents to focus on customer interactions.
• Offer Regular Training: Providing agents with training on communication and call-handling skills can help reduce unnecessary call time and improve overall efficiency. Regular training ensures agents are equipped with the skills needed to handle calls effectively.

If your team is on a budget, consider using Google Sheets to manually track AHT. This method allows you to calculate AHT using built-in formulas without the need for costly software solutions. While it may require more manual effort, it can be a cost-effective starting point for small teams.

What to Expect

AHT can vary depending on the type of call center. For example, a technical support center may have a higher AHT due to the complexity of issues handled, while a customer service center might aim for a lower AHT. Typically, a good benchmark for AHT in most customer service centers is between 4-6 minutes.

The goal is to find a balance that ensures efficiency while maintaining high-quality service.

2. First Call Resolution (FCR)

First Call Resolution (FCR) is another key KPI that measures the percentage of customer issues resolved on the first call. It reflects the effectiveness of your agents in handling customer inquiries without the need for follow-up interactions. A high FCR rate indicates that agents are well-trained and capable of solving problems quickly, leading to improved customer satisfaction.

Why It Matters

FCR is a critical indicator of customer satisfaction and operational efficiency. When customers’ issues are resolved on the first call, it reduces the need for repeat contacts, which can save time and resources. Moreover, high FCR rates contribute to customer loyalty, as customers appreciate quick and effective problem resolution. Conversely, low FCR rates may indicate gaps in training or resources.

How to Measure FCR

To calculate FCR, use this formula:

FCR = (Total Number of Calls Resolved on First Contact / Total Number of First Contacts) * 100

Ensure your call tracking system captures this data accurately. Use disposition codes or after-call surveys to confirm resolution status. Additionally, regularly reviewing this data can help identify areas for improvement, such as specific issues that are not being resolved on the first contact.

Best Practices for Measuring FCR

• Use Call Tracking and Analytics: Tools like Salesforce Service Cloud offer detailed insights into call outcomes, helping you track FCR accurately. Analyzing these insights can highlight common problems and provide opportunities for targeted training.
• Review Call Logs Regularly: Frequently analyze call logs to identify common issues and trends in agent performance. This practice helps in targeting specific areas for improvement and enhancing overall FCR rates.
• Empower Agents with Knowledge Bases: Providing comprehensive knowledge bases and ongoing training helps agents resolve issues on the first call, thereby improving FCR rates. Knowledge bases act as a quick reference guide for agents, reducing the need for escalations.

Case Study: Veev’s FCR Improvement

Veev improved their FCR from 65% to 82% in six months by implementing a new knowledge base and offering regular training on common customer issues. As a result, this led to a 20% reduction in repeat calls and a 15% increase in customer satisfaction scores.

What to Expect

A good FCR rate is typically above 70-80% in most industries. However, this can vary depending on the complexity of the issues handled. For example, technical support centers might have a lower FCR due to the nature of the inquiries. Higher FCR rates generally lead to increased customer satisfaction and reduced operational costs because fewer repeat calls are needed.

3. Occupancy Rate

Occupancy Rate measures the percentage of time agents are actively engaged with customers, whether talking or performing after-call work, compared to their total logged-in time. This metric helps determine how effectively your agents are utilized and whether there is room to improve productivity. A balanced occupancy rate ensures agents are neither overworked nor underutilized.

Why It Matters

Understanding occupancy rates is essential for managing agent workload and optimizing staffing. If the occupancy rate is too high, agents may experience burnout, which can lead to increased turnover and decreased service quality. Conversely, if the rate is too low, it might suggest under-utilization, resulting in higher operational costs. Thus, finding the right balance is crucial for maintaining an efficient and healthy work environment.

How to Measure Occupancy Rate

To calculate Occupancy Rate, use this formula:

Occupancy Rate = (Total Talk Time + Total After-Call Work Time) / (Total Logged-In Time) * 100

This formula provides a percentage that represents how much time your agents spend actively working compared to being idle or on break. Additionally, by monitoring occupancy rates over time, you can identify staffing needs and optimize agent schedules more effectively.

Best Practices for Measuring Occupancy Rate

• Monitor in Real-Time: Use real-time dashboards to track occupancy rates and adjust staffing as needed. Tools like Five9 and Genesys Cloud CX provide robust monitoring capabilities. Real-time monitoring helps in making quick decisions to prevent both overstaffing and understaffing.
• Balance Workload: Ensure agents have a balanced workload to prevent burnout and maintain service quality. Workforce management tools can help distribute workload evenly across all shifts, ensuring optimal performance.
• Analyze Historical Data: Review past occupancy data to identify patterns and make informed staffing decisions based on trends. For instance, understanding peak call times can help in planning shifts more effectively.

4. Customer Satisfaction (CSAT)

Customer Satisfaction (CSAT) measures how happy customers are with the service they received. It is usually collected through surveys conducted immediately after a customer interaction. CSAT is a direct reflection of your team’s performance and the quality of customer experience provided.

Why It Matters

CSAT is a vital metric because it provides direct feedback from customers about their experiences. High CSAT scores typically indicate satisfied customers who are more likely to remain loyal and recommend your services to others. Conversely, low scores can signal dissatisfaction, potentially leading to customer churn. Therefore, understanding and improving CSAT is crucial for long-term success.

How to Measure CSAT

To calculate CSAT, use the following formula:

CSAT = (Number of Satisfied Customers / Number of Survey Responses) * 100

Surveys usually ask customers to rate their satisfaction on a scale, such as 1 to 5. The highest ratings (4 and 5) are considered “satisfied.” By regularly collecting and analyzing CSAT scores, you can identify areas for improvement and take actionable steps to enhance the customer experience.

Best Practices for Measuring CSAT

• Use Post-Call Surveys: Send automated surveys immediately after a call to capture customer sentiment while the experience is still fresh. This approach ensures more accurate feedback.
• Collect Feedback from Multiple Channels: Gather feedback from various channels such as phone, email, and chat to get a comprehensive view of customer satisfaction across all touchpoints. This helps in identifying channel-specific issues.
• Analyze Feedback Regularly: Use tools like Qualtrics or SurveyMonkey to analyze feedback and pinpoint areas for improvement. Regular analysis can help track progress over time and measure the impact of any changes implemented.

It’s important to compare your CSAT against industry standards and continuously work on improving customer satisfaction through regular feedback and process enhancements.

5. Net Promoter Score (NPS)

Net Promoter Score (NPS) measures customer loyalty by asking one simple question: “How likely are you to recommend our service to a friend or colleague?” NPS helps you understand the overall perception of your brand and predict future customer behavior. This metric is particularly valuable for identifying promoters (loyal customers who advocate for your brand) and detractors (unsatisfied customers who may spread negative feedback).

Why It Matters

NPS is crucial because it provides a clear indicator of customer loyalty and long-term satisfaction. High NPS scores typically mean that customers are happy with your service and likely to recommend your company, driving positive word-of-mouth and growth. Conversely, low NPS scores can highlight areas of dissatisfaction that may require immediate attention to prevent customer churn.

Thus, NPS serves as both a measure of current performance and a predictor of future growth.

How to Measure NPS

To calculate NPS, subtract the percentage of detractors (customers who rate their likelihood to recommend at 0-6) from the percentage of promoters (customers who rate 9-10):

NPS = % Promoters - % Detractors

This formula provides a score ranging from -100 to 100, indicating the overall sentiment of your customer base. A higher score is better, reflecting a larger number of promoters versus detractors. Regularly measuring NPS allows you to track changes in customer loyalty over time and implement strategies to improve it.

Best Practices for Measuring NPS

• Segment Your NPS Surveys: Divide your surveys by customer type (e.g., new vs. returning) to gain more detailed insights into different customer groups. This segmentation can help tailor your strategies to each group’s unique needs.
• Follow Up with Detractors: Reach out to detractors to understand their concerns and address any issues quickly. For example, a follow-up email or call can help turn negative experiences into positive ones.
• Use NPS Software: Platforms like Medallia and Delighted specialize in NPS tracking and provide advanced analytics to help you understand customer sentiments better. These tools can automate survey distribution and provide deep insights into customer loyalty.

6. Service Level (SLA)

Service Level (SL) or more commonly referred to as SLA (Service Level Agreements) measures the percentage of calls answered within a specified time frame, such as 30 seconds. This metric is essential for understanding how responsive your call center operations are to incoming call volumes. Maintaining a high service level ensures that customers are not kept waiting for too long, which can enhance their overall experience.

Why It Matters

Service Level is a key measure of call center performance, reflecting how well your team manages incoming calls. A high service level indicates that your call center is responsive, meeting customer expectations efficiently. On the other hand, a low service level could point to staffing or process issues that might result in customer dissatisfaction. Thus, maintaining an optimal service level is crucial for customer retention and satisfaction.

How to Measure Service Level

Service Level is typically expressed as the percentage of calls answered within a target time frame. For example, you might aim for 80% of calls to be answered within 30 seconds. Use this formula to calculate Service Level:

Service Level = (Number of Calls Answered Within Target Time / Total Number of Calls) * 100

This formula helps determine if your staffing levels and call management processes are sufficient to meet customer expectations. Moreover, maintaining a high service level can improve overall customer satisfaction by ensuring prompt responses to inquiries.

Best Practices for Measuring Service Level

• Set Clear Targets: Define service level targets based on industry standards and customer expectations. For instance, the 80/30 rule (80% of calls answered within 30 seconds) is a common benchmark.
• Use Real-Time Monitoring Tools: Utilize tools like Twilio Flex and Amazon Connect to monitor service levels in real-time and adjust staffing as needed. Real-time monitoring enables swift adjustments to maintain service levels.
