NPS Calculator

Turn survey responses into a single loyalty number. Enter your promoters, passives and detractors and this calculates your Net Promoter Score — the standard measure of how likely customers are to recommend you.

Need more than the free basics? Calculating NPS needs responses first. A survey tool like SurveyMonkey runs the 'how likely are you to recommend us?' survey and collects the answers for you.

How NPS works

You ask one question — 'how likely are you to recommend us, 0–10?' — and group answers: promoters (9–10), passives (7–8) and detractors (0–6). NPS is the percentage of promoters minus the percentage of detractors, giving a score from -100 to +100. Above 0 is good, above 50 is excellent. Track it over time; the trend matters more than the absolute number.

Frequently asked questions

What is a good NPS score?

Anything above 0 means more promoters than detractors. Above 30 is great and above 50 is excellent, though benchmarks vary by industry.

How is NPS calculated?

Percentage of promoters (9–10) minus percentage of detractors (0–6). Passives (7–8) count toward the total but not the score. This tool does the maths.
