About the Net Promoter Metric

  • A Net Promoter Score is a simple satisfaction metric that is based on the single 11 point scale survey question "how likely are you to recommend XYZ Company to a friend or colleague?" Survey respondents are broken into 3 categories, depending on the score they give:
  • Promoters - respondents who answer a 9 or 10 to the recommend question represent a firm's strongest allies and are most likely to promote the firm to others.
  • Passives - respondents who answer a 7 or 8 to the recommend question are likely satisfied with the firm, but not out actively promoting it to others.
  • Detractors - respondents who answer with a 6 or lower are likely to be un-satisfied and may even be looking to switch to a new firm.
  • The Net Promoter Score is calculated by taking the % of promoters minus the % of detractors. The Net Promoter Score was developed by Bain consultant and author Frederick Reicheld. More information on Net Promoter Score can be found at
