How to calculate your NPS ®?

Even if our online NPS ® calculator has done it for you,
let’s go through the steps you need to know your Net Promoter Score ®.

Responses collected

First of all, gather all the answers you received to the question ” How likely would you be to recommend … to a friend or colleague?”. Identify the scores obtained and categorize them:


Score 9 or 10: your promoters. In other words: your fans. They won’t miss a chance to talk about you (and that’s a good thing).


Score 7 or 8: your passives. Basically, they’re happy with you, but open to other possibilities.


Score between 0 and 6: your detractors. They are clearly not happy. And, unfortunately, they probably want to share their bad experience with others.

Responses collected
NPS ® = % of promoters - % of detractors

Calculate NPS ®

NPS ® = % of promoters – % of detractors

To do this, you first need to determine the percentages of promoters and detractors. And you can calculate them using the formula below:


% promoters = number of promoters / number of participants * 100


% detractors = number of detractors / number of participants * 100

You got it?

Then subtract the 2 results and that’s it, you have calculated your NPS ®!
