How is NPS calculated?

The NPS survey asks customers “How likely are you to recommend *|COMPANY|* to a friend or colleague?” and they respond on a scale from 0 (very unlikely) to 10 (very likely).

Customers who answer lower than 6 are detractors, while those who respond with a 9 or higher are promoters. Customers responding 7-8 are passives

NPS is calculated by subtracting the % of detractors from the % of promoters.

NPS scores range from -100 (very bad) to +100 (very good).
