The Net Promoter Score (NPS) is a loyalty metric developed by Friedrich Reichheld. It is based on a question posed to customers: “How likely are you to recommend [company or brand X] to a friend or colleague?” Responses are given on a scale from 0 (“Very unlikely”) to 10 (“Very likely”). The NPS is calculated by subtracting the percentage of customers giving a score of 0 to 6 from the percentage of customers giving a score of 9 to 10. This score, often negative, assesses the likelihood of customers recommending a given company or brand to their network.
