Method and definitions

NPS = percentage of promoters − percentage of detractors. All three response groups are included in the denominator. The result ranges from −100 to +100 and is a score, not a percentage.

Use one response per respondent to the standard 0–10 recommendation question. Passives remain in the denominator. Small or unrepresentative samples can mislead; the tool does not declare a score good or bad. Net Promoter Score and NPS are registered trademarks of their respective owners.

Reference: Bain Net Promoter System overview.

Worked example

70 promoters, 20 passives and 10 detractors among 100 responses gives NPS +60.
