Net Promoter Score

What is Net Promoter Score?

Net Promoter Score is a simple question with powerful implications: “On a scale of 0-10, how likely are you to recommend this product to a colleague?” Customers who answer 9-10 are promoters (loyal enthusiasts). Those who answer 7-8 are passives (satisfied but not enthusiastic). Those who answer 0-6 are detractors (unhappy, likely to churn and share negative feedback).

The NPS is calculated as: % of Promoters - % of Detractors. If 60% are promoters and 20% are detractors, your NPS is 40. High-performing companies typically have NPS above 50. Low-performing companies have negative NPS (more detractors than promoters).

Why NPS Matters

NPS correlates strongly with growth and retention. Companies with high NPS grow faster because customers recommend the product. They also have lower churn because satisfied customers stay longer. Companies with negative NPS struggle—detractors are telling others the product isn’t good.

NPS is also simple to track over time and compare across competitors. This simplicity has made it a standard metric in many industries. You can see whether NPS is improving, stable, or declining, and benchmark against competitors and industry peers.

NPS by Segment

Like other metrics, NPS is more useful when segmented. Your overall NPS might be 40, but enterprise customers might be 60 (very satisfied) while SMB customers might be 20 (less satisfied). This reveals where your product creates value and where it doesn’t. Understanding that enterprise values your system reliability while SMB values ease of use helps you prioritize features.

NPS by product feature is also informative. Customers who use Feature A might have NPS of 50. Customers who don’t use Feature A might have NPS of 25. This suggests Feature A creates value and should be promoted, or customers who need it should be attracted, or customers who don’t use it need help.

Using NPS for Product Decisions

NPS is most valuable when paired with follow-up questions: Why did you give that score? What would improve your score by one point? What feature is most important? These open-ended questions turn a simple number into actionable insight. You learn what matters to customers and what to improve.

High-NPS companies also track NPS among lost customers. These detractors left for a reason. Understanding why (too expensive, missing feature, switched to competitor) helps you decide whether to win them back or focus on customers with higher LTV.

NPS Limitations

NPS is a single metric and shouldn’t be your only measure of success. A company with high NPS might be growing slowly (not acquiring fast enough). A company with lower NPS might have strong unit economics (high price point means some churn is acceptable). NPS measures customer satisfaction, not business outcomes. Use it alongside retention, LTV, and revenue metrics.

NPS can also be gamed. Incentivizing customers to give high scores corrupts the metric. Better to ask the question authentically and accept honest answers, including when customers are unhappy.

Why It Matters for Product People

NPS is powerful because it connects product quality to business outcomes. If your product changes improve NPS, you’re likely improving retention and growth. If NPS declines, you have a problem that needs investigation.

NPS also creates a feedback loop. You measure satisfaction, identify what’s driving it, make improvements, and measure again. This cycle forces discipline—you can’t ignore customers who are unhappy, and you must understand what matters to customers.

Related Concepts

NPS is a component of product metrics frameworks—tracking satisfaction alongside business metrics. It correlates with retention and churn rate. High-NPS products typically have better activation (first-time users understand the value). NPS tracking should inform product reviews and product council discussions. When NPS declines, it signals something is wrong and requires investigation and course-correction.
