How the NPS is worked out

Ask one question: how likely is someone to recommend you, from 0 to 10?

  1. Sort each answer. A 9 or 10 is a promoter. A 7 or 8 is a passive. A 0 to 6 is a detractor.
  2. Divide the promoters by all answers. Divide the detractors by all answers. Turn both into percentages.
  3. Subtract the detractor percentage from the promoter percentage.

Passives count in the total but do not move the score.

A worked example

90 customers answered: 48 promoters, 27 passives and 15 detractors.

  • Promoters: 48 of 90 is 53.33%.
  • Detractors: 15 of 90 is 16.67%.
  • NPS: 53.33 minus 16.67 is 36.67.

How to read your score

The score always sits between -100 and 100.

  • Above 0: more promoters than detractors.
  • Below 0: more detractors than promoters.
  • 100 means every answer was a 9 or 10. -100 means every answer was a 6 or lower.

Watch how the score moves between surveys and read what people wrote.

Common questions

Sort answers into promoters (9 or 10), passives (7 or 8) and detractors (0 to 6). Subtract the detractor share from the promoter share. The result is your NPS, from -100 to 100.
