What is Net Promoter Score
Customer loyalty index
NPS (Net Promoter Score) is a metric for measuring customer loyalty based on one question: "How likely are you to recommend us to a friend or colleague?" on a scale from 0 to 10.
Customer Categories
- Promoters (9-10) — loyal enthusiasts who recommend and return
- Passives (7-8) — satisfied but may switch to competitors
- Detractors (0-6) — unhappy customers who can damage reputation
Calculating NPS
NPS = % Promoters - % Detractors
Range: from -100 to +100
