Net Promoter Score (NPS)


The Net Promoter Score is calculated based on responses to a single question: How likely is it that you would recommend our company/product/service to a friend or colleague? The scoring for this answer is most often based on a 0 to 10 scale.

Those who respond with a score of 9 or 10 are called Promoters, and are considered likely to exhibit value-creating behaviors, such as buying more, remaining customers for longer, and making more positive referrals to other potential customers. Those who respond with a score of 0 to 6 are labeled Detractors, and they are believed to be less likely to exhibit the value-creating behaviors. Responses of 7 and 8 are labeled Passives, and their behavior falls in the middle of Promoters and Detractors.

The Net Promoter Score is usually calculated by subtracting the percentage of customers who are Detractors from the percentage of customers who are Promoters. For purposes of calculating a Net Promoter Score, Passives count towards the total number of respondents, but do not directly affect the overall net score.

1: How to Calculate the NPS Score

Using the below recommendation question as an example; we will use the respondent's answer to this question to calculate the NPS Score.

<radio label="Q1" type="rating">
  <title>How likely would you be to recommend <u>Company A</u> to a friend, family member or colleague?</title>
  <comment>Please select one.</comment>
  <col label="c0" value="0">0 = Not at all likely</col>
  <col label="c1" value="1">1</col>
  <col label="c2" value="2">2</col>
  <col label="c3" value="3">3</col>
  <col label="c4" value="4">4</col>
  <col label="c5" value="5">5</col>
  <col label="c6" value="6">6</col>
  <col label="c7" value="7">7</col>
  <col label="c8" value="8">8</col>
  <col label="c9" value="9">9</col>
  <col label="c10" value="10">10 = Extremely Likely</col>

To calculate the NPS Score we can either first calculate what type of respondent they are, or go straight into the score. The below is a quick and easy way to track your Promoters, Passives, and Detractors in the report. Using a Single Select (Radio) type question, we can use the below code:

<radio label="NPS" title="NPS Promoter, Passives, Detractors">
if Q1.val != None:
    if Q1.val in [9,10]:
        NPS.val = NPS.r0.index
    elif Q1.val in [7,8]:
        NPS.val = NPS.r1.index
        NPS.val = NPS.r2.index
  <row label="r0">Promoter</row>
  <row label="r1">Passive</row>
  <row label="r2">Detractor</row>

Note: we are using a virtual, this only runs when the report runs. Please see “virtuals” for more information. You can run this as a “hidden question” (where=”execute”), but make sure you put it place before launching the survey.

The actual score of the respondent is going to be calculated using a Float question type. We are going to just assign a value of 100 for Promoters, 0 for Passives, or -100 for Detractors, we use the above virtual question to determine what score to assign, please see the code below:

<float label="NPS_Score" title="NPS Score" size="1">
if NPS.r0:
    data.val = 100
elif NPS.r1:
    data.val = 0
elif NPS.r2:
    data.val = -100
