NPS formula and categories
Net Promoter Score uses a single recommendation question, usually “How likely are you to recommend us?” on a 0–10 scale.
NPS = % promoters − % detractors
- Promoters
Ratings 9–10. Enthusiastic respondents who are likely to recommend.
- Passives
Ratings 7–8. Satisfied but not enthusiastic; included in total responses but not in the subtraction.
- Detractors
Ratings 0–6. Unhappy respondents who may discourage others.
- Score range
The final score ranges from -100 to 100 after rounding the percentage-point difference.
Example calculation
If 60 respondents are promoters, 20 are passives, and 20 are detractors, total responses are 100. Promoters are 60%, detractors are 20%, and NPS is 60 − 20 = 40.
How to interpret NPS cautiously
Below 0
More detractors than promoters. Investigate friction, broken expectations, or sampling issues.
0–30
Positive, but there is room to improve the experience and reduce detractors.
31–50
Strong in many contexts; compare with your own trend and segment-level cuts.
51+
Excellent in many contexts, but still validate against industry benchmarks and qualitative feedback.
NPS calculator FAQ
How do you calculate NPS?
NPS is calculated by subtracting the percentage of detractors from the percentage of promoters. Passives count in the total response base but do not directly add or subtract from the score.
Which ratings are promoters, passives, and detractors?
On the standard 0 to 10 recommendation question, ratings 9 and 10 are promoters, 7 and 8 are passives, and 0 through 6 are detractors.
What is a good NPS score?
A positive NPS means promoters outnumber detractors. Scores above 30 are often strong and above 50 are often excellent, but benchmarks vary by industry, sample source, audience, and survey context.
Can NPS diagnose exactly what is wrong?
No. NPS is a directional loyalty metric. Pair it with open-ended feedback, customer segment cuts, and consistent sampling before making big decisions.
