Formula Used
Net Promoter Score measures loyalty by subtracting detractor percentage from promoter percentage. Passives affect total responses, but not the score directly.
NPS = (% Promoters) − (% Detractors)
% Promoters = (Promoters ÷ Total Responses) × 100
% Passives = (Passives ÷ Total Responses) × 100
% Detractors = (Detractors ÷ Total Responses) × 100
- Promoters are respondents scoring 9 or 10.
- Passives are respondents scoring 7 or 8.
- Detractors are respondents scoring 0 through 6.
- Possible NPS values range from -100 to 100.

Frequently Asked Questions
1. What is a good NPS score online?
A positive NPS is usually a healthy sign. Scores above 50 often indicate strong advocacy, while negative scores suggest users are dissatisfied or disconnected from your experience.
2. Why are passives excluded from the final score?
Passives matter because they increase total responses, but they do not push the score up or down. They often represent users who are satisfied, yet not loyal enough to recommend you.
3. Can I use this calculator for landing pages?
Yes. It works well for landing pages, checkout flows, support journeys, email campaigns, and overall website satisfaction tracking across acquisition and retention channels.
4. How many responses do I need?
More responses create a more stable result. Small samples can swing fast. For comparison reporting, use a consistent collection period and enough responses from the same audience segment.
5. Can NPS be negative?
Yes. A negative NPS means detractors outnumber promoters. That usually signals friction in product experience, expectations, support quality, or mismatch between messaging and delivery.
6. Should I compare NPS by traffic source?
Yes. Comparing organic, paid, email, social, and direct traffic can reveal where expectations differ. This helps teams prioritize experience fixes and messaging alignment by channel.
7. What does the completion rate show?
Completion rate measures responses against invites sent. It helps you evaluate survey reach, respondent engagement, and whether the collection method is producing enough feedback volume.
8. Can I download my result for reporting?
Yes. After calculating, you can export a CSV summary for spreadsheets or create a PDF report for meetings, audits, dashboards, and campaign performance reviews.
