How NPS is calculated
Net Promoter Score comes from a single question: 'How likely are you to recommend us to a friend or colleague?' answered on a 0–10 scale. Respondents are grouped into Promoters (9–10), Passives (7–8), and Detractors (0–6).
The score is the percentage of Promoters minus the percentage of Detractors: NPS = %Promoters − %Detractors. Passives count toward the total response count but not toward the score itself. The result is a whole number between −100 and +100.
A worked example
Imagine 100 responses: 60 Promoters, 25 Passives, and 15 Detractors. That's 60% Promoters and 15% Detractors, so your NPS is 60 − 15 = 45.
Note that NPS is reported as an absolute number, not a percentage — it's '45', not '45%'. Two companies can share the same score with very different distributions, which is why it's worth looking at the promoter and detractor percentages alongside the headline number.
What counts as a good score
Any score above 0 means you have more promoters than detractors. Above 30 is generally good, above 50 is excellent, and above 70 is world-class. Benchmarks vary widely by industry, so the most useful comparison is usually your own score over time.
Always pair the number with the open-ended follow-up question, 'What's the main reason for your score?' The rating tells you how customers feel; the comments tell you why — and that's where the actions live.
Frequently asked questions
- What is a good NPS?
- Above 0 is positive, above 30 is good, above 50 is excellent, and above 70 is world-class. Context matters: a 'good' score in one industry can be below average in another, so track your own trend rather than chasing a universal target.
- Are passives included in the NPS calculation?
- Passives (scores of 7–8) count toward your total number of responses but are not added or subtracted in the score. NPS is simply the percentage of promoters minus the percentage of detractors.
- Can NPS be negative?
- Yes. If you have more detractors than promoters, your score is negative, down to a minimum of −100 when every respondent is a detractor. The maximum is +100 when everyone is a promoter.
- How many responses do I need for a reliable NPS?
- There's no fixed minimum, but scores from fewer than about 100 responses can swing a lot. For segment-level NPS, aim for enough responses in each segment that one or two answers don't move the number dramatically.
