What is Net Promoter Score?

Net Promoter Score (NPS) is a mathematical classification and measurement of a consumer’s brand loyalty such that it would lead to brand recommendations and promotions. Usually measured within the scale of 1-10, it provides a simplified, yet highly effective vision of an organization's brand popularity and share-ability amongst its consumers.

For example, ever saw a YouTube video that impressed you so much that you just had to share it with your friends? What you experienced while watching that video was “delight,” which psychologically encouraged you towards sharing it with friends whom too you would like to enjoy it or benefit from it. In other words, you are promoting that video because of the service it provided, be it to delight you, make you laugh or educate you, invariant of it, the "experience" was good. Now elevate this experience to a service or product provider. As a business, you would like to know how good or bad was the customer experience in using your product or service, 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 Net Promoter Score (NPS) Survey Question and Analytics.

What is Net Promoter Score Question?

Net Promoter Score(NPS) 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?

The answer options are arranged horizontally on a scale from 0-10. Respondents are then measured based on 3 response categories where the score of Promoters is considered a good Net Promoter Score (9-10):

Respondents who gave a score of 9 or 10
Respondents who gave a score of 7 or 8
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.

How to calculate your Net Promoter Score?

Net Promoter Score Calculation is done using the Net Promoter Score Formula that calculates the overall Net Promoter Score by subtracting the percentage of Detractors from the percentage of Promoters.

Net Promoter Score Calculation with Formula
Total responses - (Detractors + Passive)Total responses
Total responses - (Promoters + Passive)Total responses
Total responses - (Promoters + Detractors)Total responses

As explained, Net Promoter Score calculation and formula is based on Promoters and Detractors calculation. NPS calculation for detractors is done with the formula as a percentage of respondents who gave 0 to 6 rating. Similarly, NPS calculation for promoters is done with the formula as a percentage of respondents who gave 9 and 10 ratings.

Net Promoter Score Example

Let's use a quick example to explain Net Promoter Score calculation using the formula!
Let's consider a scenario where 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 formula:

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