Survey calculations
NPS & satisfaction calculator
Calculate scores from response counts.
How to use this tool
Enter whole response counts. Choose which ratings count as satisfied for CSAT.
Shared links can include your settings and text. Share only information you want others to see.
Net Promoter Score
Promoters answer 9–10, passives 7–8 and detractors 0–6 on the recommendation question.
Enter at least one response to calculate a score.
NPS = 100 × (promoters − detractors) ÷ all responses. Passives count in the total.
Customer satisfaction (CSAT)
Enter at least one response to calculate a score.
Save or share your calculation
A share link includes your entered counts. These scores do not establish a trend, a representative sample or a universal good/bad benchmark. Bain explains the NPS method.
Understand a small feedback survey
Try the labelled example, then replace its counts with your own. NPS includes passives in the total; CSAT uses your selected satisfied ratings.
A score describes the responses entered here. It does not show whether a sample is representative.
