Calculating Net Promoter Score (NPS)

The Net Promoter Score (NPS) introduced in 2003 by Frederick F. Reichheld, is a simple but powerful metric to show how the organization is performing in terms of customer satisfaction and customer loyalty. More and more organizations are applying the NPS as a means of increasing loyalty and recommendation factor.

The Net Promoter Score measures with customers to what extent they would recommend a particular company, product or service to others (friends, colleagues, family, etc.). The idea behind it is simple: customers will only recommend you to their friends or acquaintances if they are truly satisfied with your company. So the better you score on this question the more customers are really satisfied and the more customers will recommend you. Specifically, the respondent is asked the following question:

To what extent would you recommend company/brand/product X to friends, family or colleagues?

The respondent answers via an 11-point scale: from 10 (very likely) to 0 (very unlikely).

Based on the answers given, we distinguish three categories of respondents:

Promoters = respondents who gave a score of 9 or 10
Passives = respondents who have given a score of 7 or 8
Detractors = respondents who have given a score of 0 to 6

The Net Promoter Score is the difference between the percentage of Promoters and Detractors. Suppose the organization has 30% Promoters and 20% Detractors, then the NPS is +10.

Feeddex helps organizations apply the NPS method and takes it one step further. It is also important to know which knobs to turn in order to improve the NPS. It is also important to understand the underlying reasons why someone gives a certain score. This information can be obtained with the following in-depth questions:
  • Why are you so excited (10-9)?
  • How can we make you even more enthusiastic? (8-7)
  • Why you are not enthusiastic (6-0).
The greatest strength of the NPS Score, the question and calculating the NPS is its simplicity. Thereby, there are considerably many companies, which use the score.
