Net promoter score
The Net Promoter Score (NPS) is often used as a 'gold standard' customer experience metric and is useful for comparing across a range of events. It is a 'customer loyalty index' whose values range from -100 to +100. A NPS of over 0 is good, over 50 is great and over 70 is ‘top-notch’. A score below 0 is bad news. Our NPS is the figure we get when we subtract the % of detractors (score 0-6) from the % of promoters (score 9-10).
