The Net Promoter Score is obtained by asking customers a single question on a 0 to 10 rating scale: “How likely is it that you would recommend our company to a friend or colleague?” Based on their responses, customers are categorized into one of three groups: Promoters (9-10 rating), Passives (7-8 rating), and Detractors (0-6 rating). The percentage of Detractors is then subtracted from the percentage of Promoters to obtain a Net Promoter score. A score of 75% or above is considered quite high. Companies are encouraged to follow this question with an open-ended request for elaboration, soliciting the reasons for a customer’s rating of that company or product. These reasons can then be provided to front-line employees and management teams for follow-up action.
