Questions fréquentes

What is a good NPS?

NPS ranges from -100 to +100. A score above 0 is generally good, above 50 is excellent, and above 70 is world-class.

How is NPS calculated?

NPS = (Percentage of Promoters) - (Percentage of Detractors). Passives are not counted in the score.

What if I have zero responses?

The calculator returns 0 to avoid division by zero, but you should not calculate NPS without responses.
