NPS (Net Promoter Score) – an indicator of the quality of customer service and consumer loyalty index. It shows how likely customers are to recommend a product, service, or organization to others. The simplicity and versatility of the NPS methodology make it widely used in industries ranging from retail to healthcare.

NPS was developed in 2003 by Bain and Company and is considered the gold standard for measuring customer experience. In traditional marketing, NPS is calculated using a one-question survey and a numerical scale from 0 (not at all likely) to 10 (extremely likely).

As a result of the responses, customers fall into one of 3 categories for determining the NPS score:

  • Promoters (score 9 or 10) – loyal customers who are ready to recommend you;
  • Liabilities (score 7 or 8) – satisfied customers but not motivated to be considered your promoter.
  • Detractors (0 to 6) – Dissatisfied customers who are unlikely to buy from you again and may even discourage others from buying from you.

How to Calculate NPS Loyalty Score

To calculate NPS, you need to subtract the number of ill-wishers from the number of loyal customers. For example, if 13% of respondents are detractors, 17% are passive, and 70% are promoters, your NPS score would be 70-13 = 57.

Why is customer loyalty important?

A loyal customer will make repeat purchases and recommend the brand to their friends. In this case, advertising campaigns will pay off faster. By constantly monitoring and improving their NPS, a business can increase customer loyalty, drive sales growth, and build a positive reputation in the marketplace. To work with the NPS indicator, a company needs to set up tools to optimize the strategy to retain customers and reduce customer churn.
