Demonstrating the success of the Net Promoter Score methodology to skeptical senior management can sometimes be difficult.  It is especially so if you are trying to prove it before your organisation has implemented any changes.

One way to prove the value of NPS® is to use external success stories and case studies to show what has been done by other organisations.  Unfortunately, finding those case studies can be very difficult.

To overcome this issue, I have decided to create a list of case studies and references that are public domain.  This blog post will be updated whenever I have new material.

This is an adjunct to my other source list post: Net Promoter Score Research: the “for” and “against” list

If you have results or a link to a published article, presentation or other source please let me know (Adam Ramshaw) and I’ll add it to this list so we can all benefit.

NPS Correlates With Expansion Revenue (B2C)

ProfitWell looked at data from two thousand companies and over ten thousand subscription consumers to identify links between NPS and customer retention and expansion.

Where as a company has higher NPS there is a stronger correlation to having more expansion revenue…

Interestingly they also interpreted some of the other data to suggest that NPS does not correlate with retention rate, see below.

They posit that high NPS companies have higher retention than low or middle NPS companies and so NPS does not predict retention.

An alternative interpretation is that to drive customer loyalty, companies need to have a higher NPS than their competitors.

Leading Retailer Proves a 1% Lift in NPS = 0.5% Increase in Revenue (B2C)

In this comprehensive study (The Effect of The Net Promoter Score on Sales: A Study of a Retail Firm Using Customer) DFS, the leading retailer in the UK living room furniture market demonstrate that increases in NPS are linked to substantial improvements in revenue.

In addition, we find that (ii) a sustained one percentage point (pp) increase in NPS across all UK stores corresponds to approximately a 0.5% increase in the company’s annual revenue. In financial terms, for DFS, this means that a one pp increase in NPS in each of its UK stores would result in an additional £3 million of company sales revenue per year. To put this in perspective, the additional annual sales revenue as a result of a one pp increase in the NPS amounts to more than the equivalent of an average infill store’s annual profit. In other words, more profit is generated by a one pp increase in NPS than by opening a new store, without having to invest the capital expenditure.
