Among the most widely used metrics for measuring customer experience are CSAT, NPS, and CES. Despite their popularity, incorrect use of these metrics is just as common. When discussing customer experience, these metrics may seem distinct, as each highlights a different aspect of the interaction. True success, however, lies in understanding this data and leveraging it to continuously improve the customer experience.
With increasing competition among organizations, precise measurement becomes an essential tool for building long-term loyalty, enhancing internal processes, and strengthening brand trust. The better you interpret these indicators, the closer you get to delivering a superior experience that encourages customers to return and recommend your services.
In this article, we will clarify the differences between these metrics, when each should be used, and which is most suitable to meet your business needs.
1. Customer Satisfaction Score (CSAT)
The Customer Satisfaction Score (CSAT) is one of the most commonly used customer experience metrics. It aims to measure a customer’s satisfaction with a specific experience or interaction at a given point in time, such as a support service, a purchase, or product usage.
This metric relies on a simple and direct question, making it easy to understand and implement across both operational and managerial teams.
What does CSAT measure?
CSAT focuses on the customer’s immediate feeling following a specific experience rather than the long-term relationship with the brand. It is thus suitable for evaluating performance quality at daily touchpoints and identifying problems quickly before they escalate.
A typical question might be:
“How satisfied are you with your experience?”
Customers rate their experience on a scale from 1 to 5, with higher values indicating higher satisfaction.

CSAT Use Cases
CSAT is highly flexible, allowing use in various contexts, such as:
Measuring customer satisfaction after a direct interaction (purchase, technical support, appointment booking).
Tracking overall satisfaction over regular intervals.
Evaluating product experience after a period of use.
The question format can also be customized easily to assess the company as a whole or a specific interaction within the customer journey.
When? CSAT Surveys
The timing of survey distribution depends on the measurement objective:
Immediately after interaction: to evaluate the quality of service or support
After using the product for a period: to assess whether expectations are met
Periodically: to monitor the evolution of the customer relationship over time
Choosing the correct timing ensures more accurate and analyzable results.
How to Calculate CSAT Score
Use a scale of 1–5 or 1–10. The CSAT score is calculated as the percentage of respondents who rated their experience as:
• 4 – Satisfied
• 5 – Very Satisfied
Divide the number of these positive ratings by the total number of responses, then multiply the result by 100 to get the satisfaction percentage.
What is Considered a Good CSAT Score?
A score above 80% often indicates a high level of satisfaction, but this number is not a fixed standard. Acceptable CSAT levels vary depending on the industry and nature of the service, as some sectors naturally record higher or lower rates than others.
Advantages of CSAT
Easy to implement and quickly understandable across the organization.
Customizable through open or closed questions to identify reasons for satisfaction or dissatisfaction.
Suitable for quick evaluations immediately after an interaction.
Helps detect operational issues as they occur.
Considered a fundamental element in measuring service quality.
Limitations of CSAT
Sometimes may not provide honest responses due to proximity to the event.
Focuses on short-term experience and does not necessarily reflect long-term loyalty.
Satisfaction does not equal loyalty; a satisfied customer may not return, whereas a loyal customer contributes to long-term business growth.

2. Net Promoter Score (NPS)
The Net Promoter Score (NPS) is used to measure customer loyalty and overall brand perception, rather than evaluating a single experience or interaction. It is one of the most widely adopted customer experience indicators globally for tracking the strength of the relationship between an organization and its customers over the long term.
This metric focuses on how willing a customer is to recommend the brand, serving as a strong indicator of trust and engagement, rather than just temporary satisfaction.
What does NPS measure?
NPS measures the likelihood of recommendation as a direct reflection of customer loyalty. Based on customer responses, they are categorized into three main groups:
Promoters: Enthusiastic customers who are likely to recommend the brand.
Passives: Relatively satisfied customers who are not emotionally engaged.
Detractors: Unsatisfied customers who may negatively impact the brand’s reputation.
This classification helps identify the groups that require reinforcement or intervention.
The core NPS question
A single, direct question is asked:
“On a scale from 0 to 10, how likely are you to recommend [company] to a friend or colleague?”
The scores are interpreted as follows:
9–10: Promoters
7–8: Passives
0–6: Detractors
When to use NPS
NPS reflects the overall relationship with customers, and it is preferred to use it periodically rather than after every interaction to obtain a stable view of customers’ perception of the brand.
It is typically used for:
Tracking loyalty development over time.
Assessing brand positioning.
Measuring the impact of long-term strategic improvements.
It can also be converted into a transactional metric when needed by linking it to a recent interaction question.
How to calculate the NPS score
The NPS score is calculated by subtracting the percentage of detractors from the percentage of promoters:
% Promoters − % Detractors = NPS score
The result ranges from -100 to +100, with higher values indicating stronger loyalty.
What is considered a good NPS score?
Generally:
Any score above 0 is considered positive.
Above 50 indicates strong performance.
Exceeding 70 is considered world-class.
However, benchmarks vary by industry and market, so it is always recommended to compare results against industry averages.
Advantages of Net Promoter Score (NPS)
Provides a clear indicator of long-term loyalty.
Less affected by individual experiences or temporary incidents.
Facilitates customer segmentation and tailored strategies for each group.
Suitable for periodic tracking and trend measurement.
Low cost and quick to implement.
Limitations of NPS
Does not explain the reasons behind the score without follow-up questions.
Requires effective management of detractors to prevent accumulation of negative experiences.
May create a false sense of success if not analyzed thoroughly.
Does not necessarily guarantee actual customer behavior, such as repeat purchases.
How NPS complements other metrics
NPS works best when combined with other metrics such as CSAT and CES. While NPS provides a broad view of loyalty, other metrics help understand satisfaction and ease of interaction, allowing for a deeper understanding of the customer experience from multiple perspectives.

3. Customer Effort Score (CES)
The Customer Effort Score (CES) focuses on measuring how easy the customer’s experience is during their interaction with a service, rather than directly assessing satisfaction or loyalty. The fundamental premise of this metric is that the less effort a customer needs to exert to accomplish what they want, the more likely they are to continue engaging with the brand.
Specialized research has shown that complex or frustrating interactions not only lead to customer loss but also encourage customers to share negative experiences with others, even if the issue is not related to the product itself.
Why is CES important?
Studies by the Corporate Executive Board (CEB) have revealed that the factor most closely linked to customer loyalty is not delight or special offers, but the efficiency and speed of problem resolution. From this insight, CES emerged as a practical tool that helps organizations assess the level of effort customers perceive during their interactions.
This metric helps identify obstacles that hinder the customer experience, whether they are complex procedures, unclear steps, or delays in resolution, enabling the organization to address them directly.
How does CES measure customer experience?
The Customer Effort Score relies on a single, direct question focusing on a specific task or interaction, such as solving an issue or completing a process. It is rated using a numerical scale, where higher scores reflect an easier experience and less effort.
Examples of CES questions:
How easy was it to complete your request or resolve your issue?
To what extent was the service clear and straightforward?
CES is usually applied immediately after the interaction, making the results accurate and closely tied to the actual experience.
When? CES surveys
CES is a transactional metric and is preferably sent immediately after the interaction, such as:
After resolving a complex technical issue.
After completing a purchase.
After the customer uses a self-service option.
This timing helps capture friction points accurately before the details of the experience fade from the customer’s memory.
Calculating the CES score
CES scores are typically calculated as a percentage or average of customer responses, focusing on positive answers that reflect ease of interaction. High scores indicate a smooth experience, while low scores highlight difficulties that require attention.
Advantages of Customer Effort Score
Provides clear indicators for improving processes and services.
Helps identify operational issues that directly affect the customer experience.
Offers actionable feedback when supported by follow-up questions.
Enhances the efficiency of customer service teams and improves interaction quality.
Supports short- and long-term customer experience initiatives.
Limitations of CES
Focuses on the service experience and does not reflect overall performance or organizational loyalty.
Does not explain the reasons behind high effort without further analysis or supplementary questions.
Does not consider factors such as price, competition, or product quality.
Does not provide detailed customer segmentation as NPS does, so it is recommended to use it alongside other metrics.
