Introducing a New Question Type: Net Promoter Score

Wednesday, April 22, 2009 by Sherrie Mersdorf
We recently added two new question types to our web survey software: Matrix Spreadsheet and Net Promoter Score. If you're not familiar with the Net Promoter Score, here's some quick background. Introduced in 2003 in a Harvard Business Review article by Frederick Reichheld, Net Promoter simplifies the complexity of measuring customer satisfaction. The Net Promoter Score gives a stable measurement of performance that can be compared across the organization or industries.

An organization can obtain their Net Promoter Score by asking customers a single question on an 11 point scale (0-10). Questions typically ask how likely the respondent is to recommend a product or service.

Example of Survey Question: Net Promoter Score

Based on the response, respondents fall into one of three categories: Detractors, Promoters or Passives. Detractors answer with a 0-6 rating. Detractors are unhappy customers who could potentially damage your brand through negative word-of-mouth. Passives answer with a 7 or 8 rating. Passives are individuals who are satisfied but are vulnerable to competitor offerings. When calculating the Net Promoter Score, Passives are ignored. Promoters answer at the top of the scale with a 9 or 10 rating. These people are loyal customers and brand enthusiasts. Promoters will continue to buy your products and refer others, ultimately fueling an organization's growth.

To calculate your Net Promoter Score, simply subtract the percentage of detractors (those who answered with a 0-6 rating) from the percentage of promoter respondents (those who gave a 9 or 10 rating)

Net Promoter Score = (% of Promoters) - (% of Detractors)

The goal is to have a high Net Promoter Score. Typically, 75% is considered a good Net Promoter Score. We recommend using an open ended question after a Net Promoter question. This allows appropriate action to be taken by employees and management to identify and resolve customer issues.

I have a Question about the formula. Do you consider the passives answers to calculate % of promoters or % of Detractors? Is the % promoter calculated by dividing the number of promoters by the total number of answers (including passives) or only by the number of Promoters and Detractors? Best Regards, Eduardo

Eduardo, you do include the passives when calculating percentage of promoters and detractors. So the steps might look more like this: First, salculate the percentage of respondents who are promoters and detractors: % of Promoters = (# of Promoters)/(Total # of Respondents) % of Detractors = (# of Detractors)/(Total # of Respondents) Second, calculate your Net Promoter Score: % of Promoters - % of Detractors = Net Promoter Score Does this help clear up the calculations a bit? Many online survey tools, including Cvent, will be automatically conduct the calculations (which for number fearing people can be a HUGE plus).

Is NPS limited to a single question or it can have more than one question each for a specific area?

Chintan - I'm not sure I understand what you're asking, but I'm going to try to answer the best I can. The NPS is one question with one set of answers to answer a question about likelihood to recommend, satisfaction, excellence, etc. You can ask it any number of times in any given survey (but beware of over using it, as it wont help you get the data you want if everything is an NPS question). At the end, you could manually average all the scores to get a survey-wide NPS, if that's something you needed.
