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.

  1. 01Promoter % = 60/100 = 60%
  2. 02Detractor % = 15/100 = 15%
  3. 03NPS = 60% - 15% = 45
