One of the best forms of advertising is word-of-mouth. When your customers love your products and services, they will tell their family and friends about them. Personal recommendations carry a level of credibility that traditional advertising often cannot match. Consumers tend to trust the opinions of people they know, making positive referrals incredibly valuable for long-term business growth. However, it can be difficult to determine what customers will recommend your products and services to their friends.
That’s where the Net Promoter Score (NPS) comes in. The NPS is based on one key survey question on your customer satisfaction survey: “How likely are you to recommend us to your friends and colleagues?”. The response scale ranges from 0 to 10.
This single question provides a simple yet powerful indicator of customer loyalty. Rather than asking multiple complex questions, NPS focuses on the likelihood of recommendation—a strong predictor of repeat business and organic growth. Because the scale is standardized, it also allows organizations to benchmark their performance over time and, in some cases, against industry peers.
Participants are classified based on their response. Those who respond with a 9 or a 10 are called active Promoters. These individuals discuss your products or services without being prompted or asked. They are enthusiastic supporters of your brand and are more likely to generate positive word-of-mouth and referrals. Promoters often demonstrate higher lifetime value, greater retention rates, and increased purchasing frequency.
Participants who respond with a 7 or 8 are considered Passives. These individuals may think highly of your products or services but would not provide information about them to others unless asked. Passives are not included in the NPS calculation. While they are generally satisfied, they may be vulnerable to competitive offers. Converting Passives into Promoters can significantly improve your overall score and strengthen customer loyalty.
Participants who answered with a score from 0 to 6 are called Detractors. Detractors are individuals who sway others away from your products or services. They may have experienced dissatisfaction, unmet expectations, or poor customer service. It’s important to consider what exactly went wrong with Detractors and why they feel the way they do. Identifying patterns in their feedback can reveal operational gaps, service breakdowns, or product issues that require attention.
You can easily calculate the NPS by subtracting the percentage of individuals who are Detractors from the percentage of individuals who are Promoters. The result is a score that can range from -100 to +100. A positive score generally indicates that you have more Promoters than Detractors, while a negative score signals potential challenges in customer experience that need to be addressed.
The NPS can be a crucial part of your customer satisfaction surveys. The score tells you how you’re doing as a business. If you do repeat customer satisfaction surveys, you can gain insight into trends. Are things getting better, worse, or staying the same? Tracking NPS over time allows you to measure the impact of strategic initiatives, product enhancements, and service improvements.
Beyond tracking trends, NPS can also be segmented to provide deeper insights. For example, you can analyze scores by customer demographics, purchase type, location, or service channel. This level of detail helps pinpoint strengths and weaknesses within specific areas of your organization. By understanding which groups are most satisfied—and which are not—you can prioritize targeted improvements.
A question assessing NPS should always be accompanied by a question asking for elaboration. This is best accomplished by an open-ended question that solicits customer feedback. Asking respondents to explain the reason behind their rating provides valuable qualitative context that numbers alone cannot capture. For example, a Promoter might highlight exceptional customer service, while a Detractor might identify a recurring delivery issue.
Qualitative feedback helps transform NPS from a simple metric into an actionable strategy. Reviewing comments allows you to identify recurring themes, celebrate strengths, and address concerns quickly. Sharing positive feedback internally can also boost employee morale, while constructive criticism can guide process improvements and training initiatives.
