Net Promoter Score

‍A net promoter score is a customer satisfaction metric in marketing that measures the likelihood that a customer would recommend a product or company to a colleague, family member or friend. It indicates stronger loyalty than just customer satisfaction, because it measures active promoters of a company. It is calculated by subtracting the percentage of detractors from the percentage of supporters, with -100 indicating that a company only has detractors, and 100 being only promoters. An NPS score can be determined with just one question: "How likely are you to recommend company or product X?"
