Net Promoter Score (NPS) subtracts the detractor share from the promoter share on a 0–10 survey.

NPS = Promoters % − Detractors % (range −100 to +100).

Tip: Enter “Promoters %” and “Detractors %” as percents of respondents (not raw counts) before you calculate.

Nps — understanding Net Promoter Score

What is NPS?

Net Promoter Score (NPS) measures customer loyalty by asking how likely they are to recommend your product (0-10 scale). It predicts business growth.

  • Promoters (9-10): Loyal fans who drive growth
  • Passives (7-8): Satisfied but vulnerable
  • Detractors (0-6): Unhappy customers who hurt brand

The Formula

NPS Calculation
NPS = % Promoters - % Detractors (range: -100 to +100)

Worked Example

Scenario: 100 responses: 60 promoters, 25 passives, 15 detractors.
Step 1: % Promoters = 60/100 = 60%
Step 2: % Detractors = 15/100 = 15%
Step 3: NPS = 60% - 15% = 45
NPS = 45 - Great score!
