How to Calculate Net Promoter Score
Formula
NPS = % Promoters - % Detractors
NPS is based on one question: "How likely are you to recommend us?" Responses fall into three groups: Promoters (9-10), Passives (7-8), and Detractors (0-6). The score ranges from -100 (everyone is a detractor) to +100 (everyone is a promoter). Passives are excluded from the final calculation but still factor into the denominator.
Example Calculation
Out of 100 survey responses: 60 are promoters, 25 are passives, and 15 are detractors.
- 01Promoter % = 60/100 = 60%
- 02Detractor % = 15/100 = 15%
- 03NPS = 60% - 15% = 45
