Net Promoter Score Calculator

NPS is the percentage of promoters minus the percentage of detractors. Group survey responses to the 0–10 "how likely are you to recommend us" question into promoters (9–10), passives (7–8), and detractors (0–6). Each group's percentage is its share of all responses, and NPS = %promoters − %detractors. Passives count toward the total but not the score directly.

NPS runs from -100 to +100. You get -100 when every respondent is a detractor and +100 when every respondent is a promoter. It is reported as a whole number, not a percentage, so a score of 45 is written "45", not "45%".

It depends heavily on your industry, region, and how you survey, so there is no universal benchmark. As a rough guide, any positive score means you have more promoters than detractors. Comparing your score over time, or against direct competitors surveyed the same way, is far more useful than a single absolute number.
