NPS stands for Net Promoter Score which is a metric used in customer experience programs.

Each customer is asked to answer the following question: “On a rating from 1 to 10, how likely would you recommend our services to a friend?”.

Usually marks from 1 to 6 are categorized as “Detractors”, marks from 7 to 8 are categorized as “Passives” and marks from 9 to 10 are categorized as “Promoters”

NPS = “Promoters %” - “Detractors %”
