About the NPS Calculator
Calculate Net Promoter Score from promoter, passive, and detractor response counts.
How the NPS Calculator Works
Response counts are totaled, each response class is converted to a percentage, and the detractor percentage is subtracted from the promoter percentage.
Formula
NPS = 100*(promoters/total - detractors/total).
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.
Required Inputs
- Promoters (scores 9-10) (required).

Accuracy and Limitations
NPS depends on question wording, sample selection, response rate, and survey timing. It should be reported with the response count and method.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
