NPS consumer loyalty index: Secrets to your growth

What is the net promoter score (NPS)?


The Net Promoter Score (NPS) is a widely used metric in business to measure customer loyalty and predict business growth potential. It assesses the likelihood that a customer will recommend a company’s products or services to others.

Developed by Fred Reichheld, it was introduced in his 2003 Harvard Business Review article titled “The One Number You Need to Grow.” NPS has become a benchmark for assessing customer satisfaction and service quality across various industries.


How NPS is calculated

NPS is calculated based on responses to a single question: “On a scale of 0 to 10, how likely are you to recommend our company/product/service to a friend or colleague?”

Based on their ratings, respondents are classified into three categories:

  • Promoters (score 9-10): Loyal enthusiasts who will keep buying and refer others, fueling growth.
  • Passives (score 7-8): Satisfied but unenthusiastic customers who are vulnerable to competitive offerings.
  • Detractors (score 0-6): Unhappy customers who can damage the brand and impede growth through negative word-of-mouth.

To calculate NPS, subtract the percentage of detractors from the percentage of promoters. The score ranges from -100 (if every customer is a detractor) to 100 (if every customer is a promoter).

A positive score is generally good, a score above 50 is considered excellent, and above 70 is exceptional.


Application and importance

Companies use NPS to assess and improve various aspects of the customer experience. It is a simple metric that can be tracked regularly, making it a useful tool for measuring changes in customer perceptions over time.

Companies often correlate NPS with revenue growth, suggesting that a higher NPS indicates a healthier business.

For instance, Apple is frequently cited for its high NPS, often exceeding 70, indicating strong customer loyalty and a high likelihood of repeat purchases and referrals.

This closely correlates with their consistent market success and innovations in customer experience.


Criticism and limitations

While NPS is popular for its simplicity and ease of use, it is not without criticism. Some argue that NPS fails to capture the complexity of customer relationships and can be misleading if used in isolation.

For example, it does not differentiate between passive contentment and true enthusiasm, as both 0 and 6 are treated the same as detractors.

Additionally, NPS does not provide specific information about which aspects of a product or service need improvement.


Despite its limitations, NPS remains a valuable tool for many companies, offering a quick overview of where a company stands in terms of customer loyalty.

When used in conjunction with other metrics, it can provide a comprehensive view of customer experience and business health.

In conclusion, NPS is more than just a number; it reflects a company’s ability to create loyal customers who will act as brand ambassadors.

It is essential to measure NPS regularly and respond thoughtfully to the feedback it generates, allowing companies to better align their strategies with customer needs, leading to sustainable growth and success.



Why understanding the nps loyalty index is crucial


Understanding the Net Promoter Score (NPS) is crucial for companies aiming to assess and improve customer loyalty, service quality, and overall market performance. NPS serves as a simple tool for measuring customer satisfaction and their willingness to recommend a company’s products or services to others.

This is why knowing the NPS loyalty index is vital, supported by real-world examples and statistics.


Forecasting business growth

NPS is a strong predictor of growth. A high NPS indicates that a company has more promoters than detractors, suggesting that referrals from customers are likely to attract new customers without additional marketing costs.

For example, Apple’s consistently high NPS, often exceeding 70, correlates with strong market growth and high customer retention rates, evidencing that their customer-centric approach to product and support innovations has borne fruit in creating loyal customers.


Performance evaluation

Companies use NPS to benchmark themselves against competitors and industry standards. Comparisons help identify strengths and weaknesses in customer service.

For example, an above-industry-average NPS would indicate a competitive advantage in customer service. Telecommunication companies, for example, often face lower NPS scores due to widespread industry issues.

A company scoring above the industry average stands out for its excellent execution of certain aspects, such as providing superior customer service or more reliable servicing.


Improving customer retention

NPS helps identify customers at risk of leaving. Detractors (those who score 0-6) are unhappy customers who are likely to leave and can harm the company’s reputation with negative word-of-mouth.

By understanding NPS, companies can focus on these individuals with specific interventions to improve their experience.

A financial services company noted a 15% improvement in retention after implementing a follow-up service system for detractors, which included resolving their issues and improving service quality based on their feedback.


Enhancing product and service offerings

NPS can direct companies to allocate resources for the most significant improvements. Feedback on ratings helps identify specific product features or service elements that need enhancement.

For example, a consumer electronics manufacturer may find that poor battery life is a common complaint among detractors. Addressing this directly could turn detractors into promoters, improving the overall NPS.


Facilitating employee engagement and performance

Many companies link NPS scores to employee performance metrics, using them to incentivize workers to provide exceptional service. Such alignment can improve staff focus and engagement.

For example, an airline might link crew incentives to the NPS of flights they serve. These practices encourage employees to contribute positively to customer experiences, evidenced by improved service quality and increased NPS scores.


Effective marketing

Promoters are likely to recommend the company to others, serving as a powerful form of free advertising. Higher NPS scores often correlate with increased word-of-mouth promotion, reducing the need for costly marketing campaigns.

A software development company reported a 25% increase in new customers from referrals alone after focusing on strategies to turn passive customers into promoters, thereby improving their NPS.


Long-term strategic planning

Understanding NPS helps companies shape long-term strategies, focusing on sustainable growth. This approach reflects the overall opinion and loyalty of customers, which are critical for long-term success.

A retail chain might use consistently improving NPS scores as validation of its customer service strategies, confirming that investments in training and technology are enhancing customer satisfaction.

Knowing the NPS loyalty index is important because it provides a clear and quantifiable measure of how likely customers are to recommend a company’s products or services.

This metric is not just a reflection of customer satisfaction but a beacon guiding companies in improving customer relations, enhancing product quality, and ultimately, increasing growth.

Companies that actively track and strive to improve their NPS often see a direct impact on their financial results, making NPS an invaluable tool in today’s competitive business landscape.



How to determine the net promoter score (nps) of customer loyalty


Establishing the loyalty index, also known as the Net Promoter Score (NPS), is a systematic process based on surveying customers and analyzing data to determine their willingness to recommend a company’s products. This metric is a critical measure of customer loyalty and can serve as a key indicator of potential business growth.

Here’s a detailed approach to calculating and understanding NPS:


Conducting the NPS survey

The first step is to ask customers a single question: “On a scale from 0 to 10, how likely are you to recommend our company/product/service to a friend or colleague?” This question is designed to assess overall customer satisfaction and loyalty.

Surveys can be distributed through various channels, including email, websites, post-service feedback forms, or even directly within the product or app.


Categorizing responses

Responses to the question are divided into three groups: promoters, passives, and detractors.

Suppose a company received the following feedback from customers:

  • Total responses: 100
  • Promoters: 70
  • Passives: 20
  • Detractors: 10

The calculation would be as follows:

  • Promoters: 70%
  • Detractors: 10%
  • NPS = 70% – 10% = 60

An NPS of 60 is generally considered very good. It indicates a high level of loyalty and customer satisfaction compared to the number of detractors.


Analysis and actions based on feedback

After calculating the NPS, it is important to delve deeper into the feedback from customers to understand the reasons behind their ratings.

This includes asking additional questions to detractors to identify areas for improvement and to promoters to understand their strengths.

For example, a retail company might find out through additional questioning that detractors are dissatisfied with slow delivery. By resolving this issue, they could potentially convert detractors into promoters, improving the overall NPS.


Continuous monitoring and improvement

NPS should not be a one-time measure. Regular tracking and analysis over time allow for monitoring changes in customer loyalty.

This continuous process helps tailor products, services, and customer interactions. For instance, a SaaS (Software as a Service) company might track NPS monthly, correlating changes in scores with recent product updates or improvements in customer service.


Gaining and understanding the NPS loyalty index provides valuable insights into where a company stands in terms of customer loyalty and satisfaction.

This resolution helps identify what drives customers to recommend and what may deter them. Acting on this information, companies can make targeted improvements that foster customer loyalty and, ultimately, ensure sustainable business growth.


Interesting facts about the NPS


Origin and global adoption

Introduced by Fred Reichheld in 2003 in a Harvard Business Review article titled “The One Number You Need to Grow,” NPS has since been widely adopted by thousands of companies worldwide as the standard metric for measuring and managing customer loyalty.

Companies across various sectors, from retail to technology, use NPS to assess their customer relationships.


Simplicity and power

One of the most striking features of NPS is its simplicity. It categorizes customers into three groups based on a single simple question, making it incredibly easy to implement.

Despite this simplicity, NPS is a strong predictor of growth. For example, a telecommunications company might find that a 7-point increase in its NPS correlates with a 1% increase in growth rate, highlighting how small improvements can have a significant impact.


Wide range of acceptable scores

NPS can vary significantly across different industries. For instance, the luxury hotel sector might have an average NPS of 70 or higher, reflecting high customer expectations and satisfaction.

Conversely, cable and internet providers might have an average NPS around 0 or even negative due to widespread customer dissatisfaction in these industries. This diversity underscores the importance of industry standards rather than universal standards.


Connection to revenue

NPS is not just a vanity metric. It directly correlates with revenue growth.

Research shows that leaders in NPS grow more than twice as fast as their competitors.

For example, a major e-commerce platform found that its most loyal customers (Promoters) are five times more likely to make a repeat purchase and seven times more likely to try new offerings compared to Detractors.


Application beyond customers

While traditionally used to measure customer loyalty, NPS is also applied within companies to assess employee satisfaction and loyalty, known as eNPS (Employee Net Promoter Score).

Companies such as a European bank have implemented eNPS to measure employee engagement and found that higher eNPS scores closely correlate with higher customer NPS scores, evidencing that employee satisfaction directly affects customer satisfaction.


Impact on securities

Investors and analysts sometimes consider NPS data as part of their assessment of a company’s health and prospects. Studies have shown that companies with excellent NPS scores generally perform better in the stock market, indicating that the market recognizes the link between customer satisfaction and long-term profitability.


Predictive nature

NPS not only reflects current customer loyalty but can also predict future business performance. For instance, an automobile manufacturer discovered that regions with higher NPS scores at dealership points show stronger sales growth in subsequent months, marking NPS as a leading indicator of future sales success.



Cultural differences in ratings

Cultural differences can significantly influence NPS, as customers in different regions may have different tendencies in scoring. For example, Japanese customers are generally more conservative in high ratings, which could lead to lower NPS scores for businesses in Japan compared to their branches in more emotive cultures such as the United States.

These facts about NPS underscore its value as a versatile and powerful tool for assessing customer loyalty and predicting business performance. Its ability to simplify complex customer emotions into actionable data makes it an integral part of modern business strategies.


Errors in calculating the net promoter score (NPS)


Incorrect timing of surveys

Conducting an NPS survey at the wrong time can distort the results. For example, surveying customers immediately after a purchase can capture their excitement and lead to artificially high scores.

Conversely, if the survey is delayed too long after the experience, the customer’s enthusiasm may have faded, leading to lower scores.

Ideally, the survey should be sent after the customer has had enough time to evaluate the product or service but while their impressions are still fresh in their memory.


Survey fatigue

Survey fatigue occurs when customers are asked too many questions or surveyed too often, which can lead to a lack of interest and unrepresentative responses. For example, a retail company noticed a decrease in response rates and lower NPS scores when they increased the frequency of their surveys from quarterly to monthly.

Reducing the frequency and number of questions can help maintain high-quality and accurate responses.


Sampling bias

Failing to obtain a representative sample of customers can lead to skewed NPS results.

If only specific types of customers are surveyed (e.g., those who have contacted customer support), the results may not reflect the overall customer base.

A financial firm improved accuracy by expanding its surveys to include a broader demographic that was previously unaccounted for.


Misinterpretation of the score

Understanding what NPS actually measures is critical. NPS measures the likelihood that customers will recommend a business, not overall satisfaction or loyalty.

For example, a high NPS score in a monopolistic industry may not necessarily indicate high customer satisfaction but rather a lack of alternatives.

Companies should use NPS alongside other metrics to gain a more comprehensive view of customer attitudes and behaviors.


Lack of action on feedback

Collecting NPS data without taking action based on the insights can be a critical error. NPS should be a starting point for deeper investigation into customer satisfaction and loyalty.

For example, a telecommunications company initially ignored qualitative feedback associated with its NPS surveys, leading to recurring issues that were not addressed, ultimately slowing NPS growth despite various promotional efforts.


Overlooking passives

Ignoring or mismanaging passive scores (7-8) can be a mistake. These customers are satisfied but not enthusiastic enough to become promoters.

However, they are at risk of turning into detractors if their issues are not resolved. A software development company realized that it could significantly improve its overall NPS by focusing on turning passives into promoters through targeted follow-ups and special offers.


Cultural differences in interpretation

Cultural differences can affect how customers respond to surveys. In some cultures, it’s uncommon to give top marks, which can lead to lower NPS scores compared to more expressive cultures.

A global e-commerce platform adjusted its interpretation of NPS scores by region, finding that scores from customers in Japan were systematically lower than those from customers in the U.S., despite similar levels of customer satisfaction.


Inconsistent survey methods

Changing the survey delivery method across different customer segments can lead to inconsistencies in data collection, affecting NPS. A multinational company standardized its survey methods, using uniform questions and mediums across all regions, ensuring more reliable and comparable NPS data.

By avoiding these common errors in calculating NPS, businesses can obtain more accurate, meaningful, and actionable measures of customer loyalty. By carefully designing the survey process, correctly interpreting results, and integrating feedback into business operations, companies can effectively use NPS to stimulate business growth and improve customer satisfaction.
