Net Promoter Score (NPS) asks one question: "How likely are you to recommend this event to a colleague or friend?" on a 0–10 scale. Respondents are classified as Promoters (9–10), Passives (7–8), or Detractors (0–6). NPS equals the percentage of Promoters minus the percentage of Detractors. For events, a score above +50 is considered excellent and correlates strongly with high re-registration rates and organic word-of-mouth growth.
NPS is most valuable when tracked across multiple editions of the same event, revealing whether experience improvements are translating into measurably higher satisfaction. A sudden drop in NPS for a specific session track or ticket category points to a specific area to fix, not a vague sense that "things could be better."
EventHex's post-event survey tool calculates NPS automatically and segments results by ticket type, session track, or attendee cohort — so organisers see not just the overall score but which parts of the programme drove it up or down.
