Frequently Asked Questions
How is NPS calculated?
Subtract the percentage of detractors, who score 0 to 6, from the percentage of promoters, who score 9 or 10. Passives at 7 or 8 count toward the total but not the score. Results range from minus 100 to plus 100.
What is a good NPS in 2026?
Anything above zero means you have more promoters than detractors. Scores above 30 are generally strong, and above 50 is excellent in most industries. The trend over time matters more than any single reading.
