The NPS formula
Customers answer “How likely are you to recommend us to a friend or colleague?” from 0 to 10. Scores of 9–10 are promoters, 7–8 are passives and 0–6 are detractors.
In the example above, 116 of 200 people are promoters (58%) and 32 are detractors (16%), so the NPS is 58 − 16 = +42.
What the score means
These are common rules of thumb, not industry benchmarks. Your own trend over time matters more.
- Below 0: more detractors than promoters.
- 0 to 30: positive, with room to grow.
- 30 to 50: good.
- 50 to 70: excellent.
- Above 70: exceptional.

How do you calculate NPS?
Subtract the percentage of detractors (scores 0–6) from the percentage of promoters (scores 9–10). Passives (7–8) count towards the total number of responses but not the score.
Can NPS be negative?
Yes. NPS runs from −100 (everyone is a detractor) to +100 (everyone is a promoter). A negative score means you have more detractors than promoters.
Is NPS a percentage?
No. Although it is worked out from percentages, NPS is reported as a whole number between −100 and +100, like +42.
How many responses do I need?
There is no fixed minimum, but with only a few dozen responses the score can swing a lot from one survey to the next. Compare trends over larger samples.
Can Rirofeed calculate NPS for me?
Yes. Every Rirofeed NPS form calculates your score, the promoter, passive and detractor split and a 30-day trend automatically. See NPS surveys.
