What is Net Promoter Score (NPS) and how do you use it to measure customer satisfaction?

What is Net Promoter Score (NPS)?

The Net Promoter Score is a simple but powerful metric that indicates how likely customers are to recommend your product or service to others. The concept was introduced in 2003 by Fred Reichheld of Bain & Company and has since become a globally used standard for measuring customer satisfaction and loyalty.

NPS is measured with one simple question:
"How likely would you be to recommend us to a friend or colleague?"

Customers answer this question on a scale of 0 to 10, where 0 means very unlikely to recommend and 10 means very likely to recommend.

Based on their answers, customers are classified into three groups:

• Promoters (score 9-10): These are your most satisfied customers. They are enthusiastic about your brand and are likely to actively recommend you to others.
• Passives (score 7-8): These customers are satisfied but not enthusiastic enough to recommend your company. They may be sensitive to competitor offers.
• Detractors (score 0-6): These are dissatisfied customers who may give negative feedback and will not recommend your company.

The NPS score itself is calculated by subtracting the percentage of Detractors from the percentage of Promoters. The result is a score that can range from -100 to +100.

How do you calculate the Net Promoter Score?

Calculating the NPS is quite simple. Let's look at how this works using an example:

Suppose you have 100 customers answering your NPS question. The result is as follows:

60 customers give a score of 9 or 10 (Promoters).
30 customers give a score of 7 or 8 (Passives).
10 customers rated from 0 to 6 (Detractors).
The NPS is then calculated as follows:

• Calculate the percentage of Promoters: (60/100) x 100 = 60%.
• Calculate the percentage of Detractors: (10/100) x 100 = 10%.
• Subtract the percentage of Detractors from the percentage of Promoters: 60% - 10% = NPS of 50.

In this example, your NPS score would be 50. In general, the higher your NPS, the better your customer loyalty and satisfaction.

Why is NPS important?

The Net Promoter Score is a valuable indicator of customer satisfaction for several reasons:

• Simple and direct: NPS is easy to understand and implement. With just one question, you can gather valuable insights.
• Focus on loyalty: Instead of just looking at satisfaction, NPS focuses on loyalty and recommendations, which is a strong indicator of future growth.
• Comparability: Since NPS is a widely used metric, you can compare your score with that of other companies in your industry. This helps you see where you stand compared to the competition.
• Action-oriented: The NPS not only provides a score, but also allows you to ask follow-up questions. This allows you to better understand why a customer gave a certain score, so you can make targeted improvements.

How do you use NPS to improve customer satisfaction?

Collecting your NPS data is the first step, but the real benefit of NPS comes from what you do with that data. Here are some ways you can use NPS to improve customer satisfaction and loyalty:

• Analyse feedback: Always include an open-ended question after the NPS question, such as: "What is the main reason for this score?" This helps you understand why customers promote or criticise you. You will get concrete feedback that you can use immediately to improve your services or products.
• Segment your customers: By dividing customers into Promoters, Passives and Detractors, you can take targeted actions. Promoters you can reward and use as ambassadors for your brand, while you can communicate with Detractors to find out what is going wrong and how you can help them.
• Monitor trends: By monitoring your NPS over time, you can spot trends in customer satisfaction. If your score drops, it may indicate a problem you need to address. If your score rises, you know you are on the right track.
• Encourage word of mouth: Customers who promote you like to do so based on positive experiences. Make it easy for these Promoters to share their recommendations, for example through social media or customer reviews.
• Strengthen customer relationships: Focus your attention on Detractors. By actively approaching them and solving their problems, you may be able to convert them into satisfied customers. This can not only increase your NPS, but also strengthen your customer loyalty.

Conclusion: NPS as a tool for sustainable growth

The Net Promoter Score is a simple but powerful tool for understanding your customers' satisfaction and loyalty. By regularly measuring your NPS and taking action based on the feedback you receive, you can improve your service and strengthen customer relations.
