1. Average Handle Time (AHT)

Average Handle Time (AHT)

2. First call resolution (FCR)

First call resolution (FCR) is a metric used by customer service teams to measure the percentage of customer inquiries or issues that are successfully resolved on the first interaction with the customer support team.


3. Customer satisfaction score (CSAT)

Customer satisfaction levels are measured by post-interaction surveys, which provide insights into the whole customer experience.

4. Net Promoter Score (NPS)

Customer loyalty is measured by the likelihood of customers recommending the company’s products or services. 

The NPS is then calculated by subtracting the Detractor’s percentage from the Promoter’s. 

Net Promoter Score (NPS)

A positive score indicates a positive net sentiment, while a negative score suggests that there are more detractors than promoters.

5. First Response Time (FRT)

FRT measures the time it takes for a customer to receive the first response when reaching out through channels like chat, email, or social media.

The formula for calculating the first response time depends on the specific channel and the period under consideration.

6. Average Speed of Answer (ASA)

The average speed of answer (ASA) is a metric used in call centers to measure the average time it takes for an agent to answer a call.

7. Employee Satisfaction (ESAT)

ESAT evaluates call center agents’ job satisfaction and engagement levels, impacting overall team performance and customer interactions.

The ESAT formula is calculated by taking the number of satisfied employees and dividing it by the total number of employees surveyed, then multiplying that number by 100. 

Employee Satisfaction (ESAT)

8. Retention Rate

Retention rate refers to the percentage of employees that remain with a company over a certain period of time. It is a crucial metric for businesses to track as it indicates how effectively they retain their talent and reduce turnover.

A high retention rate usually indicates that the company has a positive work environment, good benefits, and opportunities for growth and development.

On the other hand, a low retention rate may suggest that employees are dissatisfied with their work, feel undervalued, or lack opportunities for career advancement.
