Definition
NPS classifies respondents as promoters (9-10), passives (7-8) or detractors (0-6), subtracting detractors from promoters. Blunt but universally comparable - and the open follow-up question is where the actual intelligence lives.
Why it matters
Tracking NPS alongside cohorts reveals whether growth is buying satisfaction or masking erosion.

% Promoters - % Detractors
