NPS: One Number From Three Groups

Net Promoter Score sorts customers into promoters, passives, and detractors, then subtracts detractors from promoters. The result fits on a scale from -100 to 100.

What is the NPS Calculator?

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.

How to use it

  1. Enter promoter, passive, and detractor counts.
  2. Click Calculate NPS.
  3. Read the score alongside survey comments.

Worked example

With 60 promoters, 25 passives, and 15 detractors from 100 responses, NPS is 45.

What is a good NPS?

It depends on industry and context, so track your own trend over time rather than chasing a universal target.

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.
