Net Promoter Score (NPS) Question, Formula, Calculation and Example

What is Net Promoter Score?

Ever saw a puppy or kitten video that you found so adorable that you just had to share it with your friends? What you experienced while watching that video was “delight,” which pushed you towards sharing. In other words, you are promoting that video. Now elevate this experience to a service or product provider. As a business, you would like to know how good or bad was the experience of a consumer, such that they would: Promote your brand, stay Passive, or even Detract from your brand.

But what if you had to measure such a response in the most scientific way? This is where we bring in the Net Promoter Score.

Net Promoter Score is a mathematical classification of a consumer’s brand loyalty. Usually measured within the scale of 1-10, it provides a simplified, yet highly effective vision of a provider’s brand popularity and share-ability amongst its consumers.

What is Net Promoter Score Question

The Net Promoter Score Question is an industry tested standard question which asks the user of a product/service the following:

Considering your complete experience with our company, how likely would you be to recommend us to a friend or colleague?

In most cases of the answer options are arranged horizontally on a scale from 0-10. Respondents are then measured based on 3 response categories:

  • Promoters – Respondents who gave a score of 9 or 10.
  • Passive – Respondents who gave a score of 7 or 8.
  • Detractor – Respondents who gave a score from 0 to 6.

The Net Promoter Score Question is simple, but the responses collected to this one question could be critical to your organization’s growth strategy. This is especially the case when you are considering the future of your product/service and how it can grow “organically” through word-of-mouth.

In terms of financial decisions, responses to the Net Promoter Score Question can offer unique forecast into how much you may have to allocate towards paid outreach and advertisements based on the current state of organic growth.

What is the Net Promoter Score Formula for Calculation?

Calculating Net Promoter Score manually for small responses can be done with ease.

Net Promoter Score Formula for Promoters  =  
Total responses - (Detractors + Passive)Total responses
 *  100
Net Promoter Score Formula for Passive  =  
Total responses - (Promoters + Detractors)Total responses
 *  100
Net Promoter Score Formula for Detractors  =  
Total responses - (Promoters + Passive)Total responses
 *  100

Typical Net Promoter Score Example

Let's use a quick example to explain Net Promoter Score – how, when and why!
Let's take a business which wants to calculate Net Promoter Score for product X amongst its 50 consumers.

Now let's say after the responses are collected, 25 of the respondents are Promoters, 15 are passive and 10 are detractors.

So based on the Net Promoter Score formulae:

Promoters  =  
50 - (15 + 10)50
 *  100 = 50%
Passive =  
50 - (25 + 10)50
 *  100 = 30%
Detractors =  
50 - (25 + 15)50
 *  100 = 20%
