How NPS is calculated

NPS = % Promoters − % Detractors

  • Promoters are respondents who scored you 9 or 10.
  • Passives scored 7 or 8. They're counted in the total but not in the score itself.
  • Detractors scored 0 through 6.

The result is a whole number between -100 and +100. A negative number means more detractors than promoters; a positive number is the inverse. For the full explainer, see What is NPS?

What to do after you calculate

A score is a starting point, not an ending one. Once you have your NPS:

  • Look at the detractors. Their open-ended responses tell you where to focus.
  • Set a recovery process. Detractors who get a follow-up convert at higher rates.
  • Track the trend. A single score is noise. A trend over time is signal.
  • Segment. NPS rolled up across all customers hides where the problem actually lives.
