Customer satisfaction metric based on likelihood to recommend.
Ask: How likely to recommend (0-10)? Promoters (9-10) minus Detractors (0-6) = NPS. Range: -100 to +100.
B2B SaaS: 30-50 is good; 50+ is excellent. Consumer: varies widely by category.
100 responses: 60 promoters, 20 passives, 20 detractors → NPS = 60% - 20% = 40.
Low response rates skew results; not following up on detractor feedback; measuring too infrequently.
Traction slide: NPS with sample size and trend if improving.
NPS 52 (n=340); up from 38 six months ago.
