Net Promoter Score
A survey measure based on a zero-to-ten recommendation question. Ratings of nine or ten are promoters, seven or eight are passives, and zero through six are detractors. Subtract the percentage of detractors from promoters using all valid responses as the denominator. The score is not a purchase forecast or proof of loyalty.
