The Net Promoter Score (NPS) is an easy way to measure an organization's customer loyalty. It measures the extent to which your customers would recommend your organization to their friends and family. The concept has been developed by Satmetrix, Bain & Company en Fred Reichheld at the start of the 21st century.
The Net Promoter Score is an index ranging from -100 to 100 that measures the willingness of customers to recommend a company’s products or services to others. It is used as a proxy for gauging the customer’s overall satisfaction with a company’s product or service and the customer’s loyalty to the brand. preprocess
Net Promoter Score Calculation
Customers are surveyed on one single question. They are asked to rate on an 11-point scale the likelihood of recommending the company or brand to a friend or colleague.
“On a scale of 0 to 10, how likely are you to recommend this company’s product or service to a friend or a colleague?”
Based on their rating, customers are then classified in 3 categories: detractors, passives and promoters.
‘Detractors’ gave a score lower or equal to 6. They are not particularly thrilled by the product or the service. They, with all likelihood, won’t purchase again from the company, could potentially damage the company’s reputation through negative word of mouth.
‘Passives’ gave a score of 7 or 8. They are somewhat satisfied but could easily switch to a competitor’s offering if given the opportunity. They probably wouldn’t spread any negative word-of-mouth, but are not enthusiastic enough about your products or services to actually promote them.
‘Promoters’ answered 9 or 10. They love the company’s products and services. They are the repeat buyers, are the enthusiastic evangelist who recommends the company products and services to other potential buyers.
The Net Promotor Score Formula
The Net Promoter Score (NPS) is determined by subtracting the percentage of customers who are detractors from the percentage who are promoters. What is generated is a score between -100 and 100 called the Net Promoter Score. At one end of the spectrum, if when surveyed, all of the customers gave a score lower or equal to 6, this would lead to a NPS of -100. On the other end of the spectrum, if all of the customers were answering the question with a 9 or 10, then the total Net Promoter Score would be 100.
