What is Net Promoter Score
Net Promoter Score (NPS) is a customer loyalty metric that measures how likely customers are to recommend a product or service to others. It's based on responses to a single question using a 0-10 scale, creating a standardized way to measure customer satisfaction.
How NPS works
NPS categorizes respondents into three groups:
- Promoters (9-10): Loyal enthusiasts who recommend to others
- Passives (7-8): Satisfied but unenthusiastic customers
- Detractors (0-6): Unhappy customers who can damage brand
How to calculate NPS
Calculate NPS by subtracting the percentage of Detractors from the percentage of Promoters. The score ranges from -100 (all detractors) to +100 (all promoters). This simple calculation provides a clear metric for tracking customer satisfaction over time.
When to use NPS
Implement NPS surveys at key interaction points to measure overall satisfaction, after significant updates, or at regular intervals to track changes in customer sentiment. Use it alongside other metrics for a comprehensive view of user satisfaction.

Scores vary by industry, but generally: above 0 is good, above 20 is favorable, above 50 is excellent, and above 80 is world-class. Compare against industry benchmarks for context.
For digital products, measure quarterly or after significant feature releases. Consider your product's usage patterns and user lifecycle when determining frequency.
No, complement NPS with other metrics like CSAT, CES (Customer Effort Score), and qualitative feedback to get a comprehensive view of user satisfaction and experience.
