How is NPS calculated?
- Ask the NPS question: "How likely are you to recommend [Company] to a friend or colleague?" Scale 0-10.
- Categorize responses: 9-10 = Promoters, 7-8 = Passives, 0-6 = Detractors.
- Calculate percentages: %Promoters = Promoters ÷ Total × 100. %Detractors = Detractors ÷ Total × 100.
- Subtract: NPS = %Promoters − %Detractors. Result is between −100 and +100.

FAQs
What is a good NPS score?
Above 0 is positive. Above 30 is good. Above 50 is excellent. Above 70 is world-class. Industry-dependent.
Should I include Passives in the calculation?
No. Passives count in the total response base but are excluded from the score itself. Only Promoters and Detractors contribute to the NPS number.
What scale should I use for the NPS question?
The standard NPS scale is 0-10 (11 points). Don't substitute with 1-5 or 1-7 — that's a different scale entirely and not comparable to standard NPS benchmarks.
How often should I run an NPS survey?
Quarterly is standard for relationship NPS. Transactional NPS can be sent immediately after specific interactions (post-purchase, post-support).
