The NPS is a customer loyalty metric derived from one question posed to customers about how likely they are to recommend a company, product, or service on a scale of 0 to 10. The respondents are then categorized as Promoters (9-10), Passives (7-8), or Detractors (0-6). The percentage of Detractors is then subtracted from the percentage of Promoters to obtain a net score ranging from -100 to +100. NPS serves as a simple but powerful measure for assessing customer satisfaction and loyalty, which is fundamental to tracking sentiment and fostering momentum for business development.
