Understanding CES

The Customer Effort Score (CES) is a customer experience metric that measures the ease of interaction with a company from the customer's perspective. It specifically gauges the effort a customer has to exert to get an issue resolved, a request fulfilled, an issue fixed, or a question answered.

How CES is Measured

CES is typically measured by asking customers a single question after an interaction, such as: "On a scale from 'very easy' to 'very difficult,' how easy was it to interact with [Company/Service]?" This question can be adjusted to fit the specific context or type of interaction being evaluated. Responses are usually given on a scale from 1 (very difficult) to 7 (very easy), although some businesses may use different scales, such as 1 to 5.

Calculating CES Score

The CES score is calculated by taking the average of all customer responses. For instance, if customers are asked to rate their experience on a scale of 1 to 7, the CES would be the average rating across all respondents. A higher average indicates that customers found it easier to interact with the company, suggesting better customer experience and potentially higher loyalty.

Uses of CES

The Customer Effort Score is used to:

  • Identify pain points in customer interactions that may affect their loyalty.

  • Measure the effectiveness of support teams and customer service processes.

  • Evaluate the user experience across various touchpoints, such as websites, apps, or physical stores.

  • Optimize processes and touchpoints to reduce customer effort, thereby improving satisfaction and potentially increasing loyalty.

Advantages and Limitations


  • Specific focus: By focusing specifically on the effort exerted by the customer, CES provides clear insights into operational efficiency and customer satisfaction related to service interactions.

  • Predictive of loyalty: Research suggests that reducing customer effort can significantly boost customer loyalty, as easier experiences are more likely to lead to repeat interactions.


  • Narrow scope: CES mainly focuses on service and support interactions and might not capture overall satisfaction or emotional connection with the brand.

  • Cultural biases: Perceptions of effort can vary widely across different cultures, which may affect the accuracy of CES in international contexts.

By focusing on how much effort customers expend in their interactions with a company, CES serves as a critical metric for businesses looking to streamline operations, improve customer interactions, and enhance overall customer satisfaction.
