What is Net Promoter Score?

The Net Promoter Score (NPS) is a widely used metric in business and marketing to measure customer loyalty and satisfaction. It is designed to gauge the likelihood that customers will recommend a company’s products or services to others


Let’s say a company named XYZ Corp. conducts an NPS survey among its customers. The survey asks the following question: “On a scale of 0 to 10, how likely are you to recommend XYZ Corp.’s products and services to a friend or colleague?”

Out of the 1000 customers who respond:

  • 400 customers rate 9 or 10 (Promoters)
  • 300 customers rate 7 or 8 (Passives)
  • 300 customers rate 0 to 6 (Detractors)

Now, let’s calculate the NPS:

Percentage of Promoters = (400 / 1000) * 100 = 40%

Percentage of Detractors = (300 / 1000) * 100 = 30%

NPS = Percentage of Promoters – Percentage of Detractors

NPS = 40% – 30% = 10

So, in this example, the Net Promoter Score for XYZ Corp. would be +10. This means that the company has more promoters than detractors, indicating a generally positive customer sentiment. However, the NPS of +10 suggests there is room for improvement in converting more customers into promoters and reducing the number of detractors to enhance overall customer loyalty and satisfaction.


The Net Promoter Score (NPS) offers several advantages that make it a popular metric for businesses to assess customer loyalty and satisfaction:

  • NPS is easy to understand and administer.
  • It involves asking a single straightforward question, making it less burdensome for both customers and businesses.
  • NPS specifically targets customer loyalty by measuring the likelihood of recommending a company.
  • Since NPS is widely adopted, it allows for easy benchmarking and comparison across different industries and companies.
  • NPS categorizes customers into promoters, passives, and detractors. This segmentation offers valuable insights into various customer segments and helps businesses understand areas that need improvement or enhancement.
  • Research has shown that NPS correlates with customer behavior such as repurchasing, referral generation, and overall customer lifetime value.
  • Higher NPS scores often correspond to better business outcomes.
  • NPS scores are easy to communicate within an organization.
  • NPS results guide businesses in making data-driven decisions, prioritizing improvements, and focusing on customer-centric strategies.
  • Compared to more elaborate customer satisfaction surveys, NPS is relatively cost-effective and requires fewer resources to implement.


While the Net Promoter Score (NPS) offers several benefits, it also has some limitations and disadvantages that businesses should consider:

  • The single-question nature of NPS can oversimplify the complex factors that contribute to customer satisfaction and loyalty.
  • It might not capture the full range of emotions and experiences that customers have with a company.
  • NPS doesn’t provide context for why customers give a certain rating. Businesses might not fully understand the reasons behind a customer’s rating without additional feedback.
  • While NPS allows for benchmarking across industries and companies, the methodologies for calculating NPS can vary. This makes direct comparisons less accurate.
  • While there is a correlation between NPS and certain customer behaviors, it might not always be a perfect predictor of customer actions like repurchasing or referrals.
  • While NPS identifies promoters, passives, and detractors, it might not offer clear guidance on how to address issues or enhance satisfaction for each group.
  • Factors outside of a company’s control, such as industry trends, macroeconomic conditions, or competitors’ actions, can influence NPS scores.
  • Some businesses might focus too heavily on improving the NPS number itself without adequately addressing underlying issues that affect customer satisfaction.
  • In some cases, organizations might fear negative feedback and discourage customers from providing honest low ratings, skewing the results.
  • NPS surveys might not reach all customer segments equally, leading to potential bias in the collected data.

What is Customer Satisfaction Score?

The Customer Satisfaction Score (CSAT) is a metric used to measure the level of satisfaction that customers have with a product, service, or overall experience provided by a company. It typically involves asking customers to rate their satisfaction with a specific interaction, purchase, or experience on a predefined scale.


Certainly, here’s an example of how a Customer Satisfaction Score (CSAT) survey might be used:

Let’s say a company named ABC Electronics recently released a new smartphone model, and they want to assess how satisfied customers are with their purchase experience. They decide to conduct a CSAT survey among a sample of their recent customers.

The CSAT survey question they ask is: “How satisfied are you with your recent purchase of our new smartphone?”

Customers are asked to rate their satisfaction on a scale of 1 to 5, with 1 being “Very Unsatisfied” and 5 being “Very Satisfied.”

Out of the 200 customers who respond:

  • 50 customers choose “Very Satisfied” (Rating 5)
  • 80 customers choose “Somewhat Satisfied” (Rating 4)
  • 40 customers choose “Neutral” (Rating 3)
  • 20 customers choose “Somewhat Unsatisfied” (Rating 2)
  • 10 customers choose “Very Unsatisfied” (Rating 1)

To calculate the CSAT score:

Number of Positive Responses = Number of Very Satisfied + Number of Somewhat Satisfied Number of Positive Responses = 50 + 80 = 130

Total Number of Responses = Sum of all responses Total Number of Responses = 200

CSAT Score = (Number of Positive Responses / Total Number of Responses) * 100 CSAT Score = (130 / 200) * 100 = 65%

In this example, the CSAT score for ABC Electronics’ new smartphone purchase experience is 65%. This means that 65% of customers reported being either “Very Satisfied” or “Somewhat Satisfied” with their purchase. The company can use this score to understand customer sentiment, identify areas of improvement, and track changes in customer satisfaction over time.


The Customer Satisfaction Score (CSAT) offers several advantages that make it a valuable metric for businesses to assess customer satisfaction and make informed decisions:

  • CSAT surveys involve a single straightforward question, making it easy for customers to understand and respond.
  • CSAT surveys can be administered quickly, allowing businesses to gather feedback on time and make prompt adjustments if needed.
  • CSAT surveys are often targeted at specific interactions or experiences, providing detailed insights into customer satisfaction related to a particular product, service, or touchpoint.
  • The direct nature of CSAT questions allows businesses to collect actionable data.
  • CSAT scores can be compared over time or across different interactions or products. This helps businesses identify trends and track improvements.
  • Customer-Centric Focus
  • CSAT scores provide a quantitative measure of customer satisfaction.
  • Addressing concerns raised in CSAT surveys can lead to higher customer retention rates by demonstrating responsiveness and commitment to improvement.
  • CSAT scores guide businesses in prioritizing improvement efforts and allocating resources where they are most needed.
  • CSAT results can be used to evaluate and reward employees based on customer satisfaction, fostering a customer-centric work environment.


While the Customer Satisfaction Score (CSAT) offers several benefits, it also has some limitations and disadvantages that businesses should consider:

  • CSAT surveys typically involve a single question and a rating scale, which can lead to a lack of depth in understanding the specific reasons behind a customer’s satisfaction or dissatisfaction.
  • The lack of context in CSAT surveys can make it difficult to pinpoint exactly what aspects of a product, service, or interaction contributed to a customer’s satisfaction or dissatisfaction.
  • CSAT surveys often result in a binary classification of satisfied or unsatisfied customers, ignoring nuances and subtleties in between.
  • A single negative experience might disproportionately impact a customer’s CSAT rating, even if they generally have positive experiences overall.
  • Customers might interpret the rating scale differently, leading to inconsistent responses across different individuals or demographics.
  •  Some customers might simply choose a middle-of-the-road rating (e.g., “Neutral”) without providing additional feedback, providing limited insights.
  • CSAT scores might indicate dissatisfaction, but they don’t inherently offer guidance on how to address the issues that led to low scores.
  • Customers who are extremely satisfied or dissatisfied are more likely to respond, leading to a sample that might not accurately represent the entire customer base.
  • CSAT might not differentiate between relatively small improvements that lead to a slightly better experience and major changes that significantly enhance satisfaction.
  • CSAT surveys are often centered around immediate experiences, potentially missing out on longer-term trends and shifts in customer sentiment.

What is Customer Effort Score?

The Customer Effort Score (CES) is a metric used to measure the ease or difficulty of a customer’s experience while interacting with a company’s products, services, or support systems. CES is designed to assess the level of effort a customer had to exert to achieve a desired outcome, such as resolving an issue, making a purchase, or using a service.


Here’s an example of how a Customer Effort Score (CES) survey might be used:

Imagine a telecommunications company called XYZ Telecom that offers internet services. XYZ Telecom wants to assess the ease of its customer support process when customers encounter technical issues. They decide to conduct a CES survey among a sample of customers who recently contacted their customer support for assistance.

The CES survey question they ask is: “How much effort did you have to put forth to resolve your technical issue with our customer support?”

Customers are asked to rate their effort on a scale of 1 to 5, with 1 being “Very Low Effort” and 5 being “Very High Effort.”

Out of the 150 customers who respond:

  • 60 customers choose “Very Low Effort” (Rating 1)
  • 50 customers choose “Low Effort” (Rating 2)
  • 30 customers choose “Moderate Effort” (Rating 3)
  • 8 customers choose “High Effort” (Rating 4)
  • 2 customers choose “Very High Effort” (Rating 5)

To calculate the CES score:

Number of Low Effort Responses = Number of Very Low Effort + Number of Low Effort

Number of Low Effort Responses = 60 + 50 = 110

Total Number of Responses = Sum of all responses Total Number of Responses = 150

CES Score = (Number of Low Effort Responses / Total Number of Responses) * 100 CES Score = (110 / 150) * 100 = 73.33%

In this example, the Customer Effort Score for XYZ Telecom’s technical issue resolution process is approximately 73.33%. This means that around 73.33% of customers found the process to be of low effort. The company can use this score to evaluate the efficiency of its customer support process and identify areas for improvement to make resolving technical issues easier and more hassle-free for customers.


  • CES directly measures the ease of customer interactions, providing insights into the level of effort customers need to expend.
  • It offers targeted insights into specific tasks, interactions, or touchpoints, enabling businesses to identify pain points and areas for improvement.
  • CES results provide actionable insights that guide businesses in making targeted improvements to enhance customer experiences.
  • High CES scores pinpoint areas of high customer effort, allowing businesses to proactively address issues before they escalate.
  • Reducing customer effort can streamline processes, leading to operational efficiencies and improved resource allocation.
  • Higher CES scores correlate with greater customer loyalty, indicating that low-effort experiences contribute to customer retention.
  • Focusing on minimizing customer effort aligns businesses with customer-centric values and improves overall satisfaction.


  • CES primarily assesses effort, potentially overlooking other important aspects of the customer experience.
  • The CES question might lack context, making it difficult to understand the specific reasons behind a customer’s rating.
  • CES scores might not capture the broader customer journey or the cumulative impact of multiple interactions.
  • The survey question often yields binary responses, which might not fully capture the nuances of customer sentiments.
  • CES might not differentiate between relatively small improvements and major changes in customer experience.
  •  While minimizing effort is crucial, overemphasis on ease might lead to a reduction in the quality or depth of customer interactions.
  • CES might not be suitable for assessing more complex or multifaceted interactions that require deeper analysis.
  • The CES scale might not capture the subtle differences in effort experienced by customers.
