About this tool
Calculate NPS from the number of promoters, passives and detractors.
NPS = % promoters (scores 9–10) − % detractors (scores 0–6). Passives (7–8) count only in the total. The result ranges from −100 to +100.
Formula: NPS = %P − %D
Example: Promoters (9–10) = 120, Passives (7–8) = 50, Detractors (0–6) = 30 → Responses = 200, NPS = 45.
Small samples give unstable scores; collect enough responses before comparing.
