How to use NPS Calculator (Net Promoter Score)
Enter the number of promoters, passives and detractors, or paste the raw scores from 0 to 10.
How it works
NPS = % promoters (9–10) − % detractors (0–6). The margin of error comes from the variance of that difference.
Example
180 promoters, 70 passives and 50 detractors give an NPS of 43.3, ±8.6 at 95 % confidence.
