What is NPS?
Net Promoter Score (NPS) measures customer experience and predicts business growth.
Formula:
NPS = % Promoters - % Detractors
Scores can range from -100 (everyone is a detractor) to +100 (everyone is a promoter).
- Promoters: Loyal enthusiasts who will keep buying and refer others.
- Passives: Satisfied but unenthusiastic customers.
- Detractors: Unhappy customers who can damage your brand.

Frequently Asked Questions
What is Net Promoter Score (NPS)?
NPS measures customer loyalty via one question: "How likely are you to recommend us?" (0-10 scale). Scores 9-10 = Promoters (loyal), 7-8 = Passives (satisfied), 0-6 = Detractors (unhappy).
How is NPS calculated?
NPS = (% Promoters) - (% Detractors). Passives are ignored in the calculation. Example: 100 responses, 50 Promoters, 30 Passives, 20 Detractors → NPS = 50% - 20% = 30.
What is a good NPS score?
NPS > 50: excellent (world-class). 0-50: good (healthy). 0: neutral/at-risk. Negative: serious problems. Industry varies: software 30-40, consumer goods 40-50, luxury brands 70+.
What is the difference between NPS, CSAT, and CES?
NPS measures loyalty/recommendation. CSAT measures overall satisfaction (1-5 scale). CES measures effort (easy vs hard). Use all three for complete customer insights.
What should I do with NPS results?
Follow up with detractors to understand problems and resolve them. Identify and replicate what promoters love. Track NPS over time to measure improvement. Set improvement targets.
How often should I measure NPS?
Monthly or quarterly is common. More frequently shows short-term fluctuations; less frequently may miss trends. Annual is minimum. Consistency matters for trend tracking.
How many responses do I need for reliable NPS?
At least 100-200 responses for statistical validity. Smaller samples (20-50) show trends but aren't reliable. Larger samples (500+) give more confidence, especially for segments.
Can NPS be negative?
Yes. NPS ranges from -100 to +100. Negative means more detractors than promoters — a serious warning sign requiring immediate action to improve customer satisfaction.
