About this tool
Enter counts of promoters, passives, and detractors, and the tool gives the NPS from -100 to 100. This is a simple score from your own survey counts, not a full customer research result, so read it alongside the comments behind it.
Frequently asked questions
Why are passives ignored in the score?
Passives are counted in the total but add to neither side, which is why a survey with many passives gives a muted score.
Is NPS enough on its own?
No. Pair it with the reasons customers gave, or you will know the score moved without knowing why.
