How it works
Three groups
Answers of 9 or 10 are promoters, 7 or 8 are passives, and 0 to 6 are detractors. Passives count in the total but not in the score.
NPS = % promoters − % detractors
Reading the score
The score runs from −100, all detractors, to +100, all promoters. 60 promoters, 25 passives and 15 detractors gives 45. Track it over time and by segment rather than against a universal bar.
