Understanding Net Promoter Score

What Is NPS?

Net Promoter Score measures customer loyalty by asking one simple question: "How likely are you to recommend our company/product/service to a friend or colleague?" Respondents rate 0-10. The score ranges from -100 to +100 and predicts business growth better than satisfaction metrics alone.

How NPS Is Calculated

NPS = % Promoters - % Detractors. Passives count toward total respondents but do not affect the score. For example, if 60% are Promoters and 20% are Detractors, NPS = 60 - 20 = 40. The score ignores Passives because they are satisfied but not enthusiastic enough to drive growth.

Why NPS Matters

Promoters buy more, stay longer, and refer new customers. Detractors spread negative word-of-mouth and can damage your brand. Tracking NPS over time reveals whether customer experience improvements are working. High NPS correlates with organic growth and lower customer acquisition costs.

Tips for Improving Your NPS

Follow up with Detractors immediately

Contact unhappy customers within 24 hours. Listen to their concerns and fix what went wrong.

Ask Promoters for referrals

Happy customers are your best salespeople. Make it easy for them to refer friends with incentives.

Close the loop on feedback

Act on what customers tell you. Share insights across teams and track improvements over time.

Survey at the right moment

Ask after key interactions (purchase, support call, onboarding). Timing affects response quality.

Frequently Asked Questions

What is a good NPS score?

Scores above 0 are positive (more Promoters than Detractors). 30-50 is good, 50-70 is excellent, and above 70 is world-class. However, context matters — compare to your industry average. Some industries naturally have lower NPS due to customer expectations.

How often should I measure NPS?

Survey quarterly for trend tracking. Some companies survey continuously and report rolling averages. Avoid surveying the same customers too frequently — wait at least 90 days between surveys to the same person to prevent survey fatigue.

Should I track NPS by customer segment?

Yes. Overall NPS can hide important differences. Segment by product line, customer tenure, geography, or account size. You might discover that new customers love you while long-term customers are becoming Detractors — critical insight for retention.

What is the difference between NPS and CSAT?

CSAT (Customer Satisfaction) measures satisfaction with a specific interaction. NPS measures overall loyalty and likelihood to recommend. CSAT is transactional; NPS is relational. Both are useful — CSAT for operational improvements, NPS for strategic health.

Can NPS be negative?

Yes. Negative NPS means you have more Detractors than Promoters. This is a warning sign that requires immediate attention. Focus on understanding why customers are unhappy and fixing root causes before trying to acquire new customers.
