How is NPS calculated?
Subtract the percentage of detractors from the percentage of promoters. Passives count toward the total but not toward either side.

Ask one question, how likely are you to recommend us on a 0 to 10 scale, with an optional follow-up. The survey form generator builds a form you can connect and send.
