Net Promoter Score (NPS)

TIL of a metric that helps measure customer engagement and loyalty: Net Promoter Score

This morning at Syndio we had our monthly team meeting where we examine how each business function stacked up against its set of KPIs from the previous month. One of the KPIs the implementation function is beginning to measure is Net Promoter Score (NPS).

What is Net Promoter Score?

NPS is a measurement of how loyal your user base is, and how much they are willing to advocate to their friends and family for your product. At Syndio, Implementation is in charge of measuring this metric, since they are the first point of contact for maintaining customer relationships: if a customer reports poor NPS, implementation is the most appropriate business function to respond.

NPS should be visible to all business functions, though, to ensure all employees understand how the product is currently viewed by the customer.

How is it measured / calculated?

NPS is measured by periodically asking customers:

How likely is it that you would recommend our product to a friend of colleague?

The customer is provided a scale from 0-10 on which to indicate their response.

  • Promoters - Respondents in the 9-10 range.
    • These are loyal customers who actively support your brand and are likely to refer others, keeping the growth engine going.
  • Passives - Respondents in the 7-8 range.
    • These are happy customers, but are not as enthusiastic about the brand, and could likely jump ship if another competitor came along…
  • Detractors - Respondents in the 0-6 range.
    • Unhappy customers who have negative opinion of your brand / product. These customers could actually harm growth by bad word-of-mouth

NPS is calculated by subtracting the percentage of respondents who are Detractors from the number of respondents who are Promoters.


Out of a survey of 100 respondents, 45 responded 9-10 and 40 responded 0-6.

NPS = 45% - 40% = 5% Promoter

What can be done with the score?

NPS should be one component of a broader customer satisfaction strategy, but it is a quick way to gain insight in to how much brand loyalty your current customers have. Once calculated, it would be interesting to look at users on edges of each spectrum: Those who responded 0 for example would likely have a particularly negative experience to share, and should be reached out to by frontline employees (ideally those already with relationships to the customer).

Understanding customer satisfaction is an important component towards shaping product strategy and development, and NPS can help clarify what parts of the product cause the most frustration / value for your customers.
