Net Promoter Score (NPS)

Net Promoter Score (NPS) is a customer loyalty metric ranging from -100 to +100, calculated by subtracting the percentage of detractors from the percentage of promoters.

Key Takeaways

  • NPS = % Promoters (9-10 rating) minus % Detractors (0-6 rating), with Passives (7-8) excluded from the calculation
  • Scores above 0 are acceptable, above 30 is strong, and above 70 is world-class across most industries
  • SaaS companies average an NPS of 30-40, while e-commerce averages 45-55
  • Survey frequency of quarterly or after key touchpoints gives the most useful trend data without survey fatigue
  • NPS alone does not explain why customers feel the way they do. Always pair the score with an open-ended follow-up question.

What Is Net Promoter Score?

Net Promoter Score (NPS) measures customer loyalty with a single question: "On a scale of 0 to 10, how likely are you to recommend us to a friend or colleague?" Responses split into three groups based on the rating given.

NPS = % Promoters - % Detractors

Promoters (9-10) are your most loyal customers. They buy more, stay longer, and refer others. Passives (7-8) are satisfied but not enthusiastic. They will switch to a competitor if given a better offer. Detractors (0-6) are unhappy customers who can damage growth through negative word-of-mouth.

The score ranges from -100 (every respondent is a detractor) to +100 (every respondent is a promoter). If you survey 200 customers and 120 are Promoters (60%), 50 are Passives (25%), and 30 are Detractors (15%), your NPS is 60 - 15 = 45. Passives count toward the total response base but do not directly affect the score.

Why NPS Matters

NPS is a leading indicator of retention. Detractors churn at 2-3x the rate of promoters in most subscription businesses. A SaaS company with an NPS of 20 that drops to 5 over two quarters should expect a churn increase 3-6 months later, well before the revenue impact shows up in financial reporting.

Promoters drive referral revenue. Bain & Company's original research found that in most industries, promoters account for 80%+ of referrals. For a B2B company where 30% of new deals come from referrals, a rising promoter percentage directly reduces customer acquisition cost.

NPS gives every team a shared metric. Product teams use it to prioritize features. Support teams track it after ticket resolution. Sales teams monitor it during renewal cycles. Unlike revenue metrics that lag, NPS moves within weeks of a product change or service failure, giving operators time to react.

How to Improve NPS

  1. Close the loop with detractors. Reach out within 48 hours of a low score. Ask what went wrong and what would fix it. Companies that close the loop convert 10-15% of detractors into promoters. A simple phone call or personalized email from a senior team member is often enough.
  2. Fix the top 3 complaint themes. Export all detractor comments, tag them by theme, and rank by frequency. If "slow support response" appears in 35% of detractor feedback, that is your highest-ROI fix. Do not spread effort across 20 issues. Fix the top 3 and resurvey.
  3. Convert passives to promoters. Passives (7-8) are the easiest group to move. They are already satisfied. Find out what would make them a 9 or 10. Often it is a small thing: better onboarding documentation, a proactive check-in call, or a feature they did not know existed.
  4. Survey at the right moment. Relationship NPS works best quarterly. Transactional NPS should fire after meaningful interactions like onboarding completion, a support case resolution, or a renewal. Avoid surveying during known pain points like billing cycles or system outages unless you want to measure those specifically.
  5. Share scores transparently with the team. Post NPS by segment in a weekly standup or shared dashboard. When support, product, and sales all see the same number, accountability follows. Teams that track NPS weekly improve scores 10-20% faster than those reviewing monthly.

Frequently Asked Questions

What is a good NPS score?

Any score above 0 means you have more promoters than detractors. A score between 30 and 50 is considered strong for most industries. Above 70 is exceptional and typically reserved for brands with cult-like followings. The most useful comparison is against your own industry, not a universal number. SaaS companies averaging 30-40 are performing well; a telecom company hitting 20 is outperforming its peers.

How is NPS calculated?

Ask customers one question: "How likely are you to recommend us to a friend or colleague?" on a 0-10 scale. Group responses into Promoters (9-10), Passives (7-8), and Detractors (0-6). Then calculate NPS = % Promoters minus % Detractors. If 60% are Promoters and 20% are Detractors, your NPS is 40.

NPS vs CSAT: what is the difference?

NPS measures overall loyalty and willingness to recommend. CSAT measures satisfaction with a specific interaction or transaction. NPS is a relationship metric best surveyed quarterly. CSAT is a transactional metric best triggered after a support ticket, purchase, or onboarding event. Most companies track both because they answer different questions.

How often should you survey NPS?

Quarterly is the most common cadence for relationship NPS. This gives enough time for scores to shift meaningfully without burning out respondents. Transactional NPS, triggered after specific events like onboarding or renewal, can run continuously. Avoid surveying the same customer more than once per quarter to prevent fatigue and response bias.

What are promoters, passives, and detractors?

Promoters (9-10) are loyal customers who actively refer others and drive organic growth. Passives (7-8) are satisfied but unenthusiastic, making them vulnerable to competitor offers. Detractors (0-6) are unhappy customers who can damage your brand through negative word-of-mouth. The gap between the 7-8 range and 9-10 is intentionally large because research shows only the highest scores correlate with actual referral behavior.

Does NPS predict growth?

The original Bain & Company research found a correlation between NPS and revenue growth in several industries. However, NPS alone is not a reliable growth predictor. Companies with high NPS but poor pricing, weak distribution, or small addressable markets still struggle. NPS is best used as one signal among several, including retention rate, expansion revenue, and referral volume.

What should I do with NPS detractor feedback?

Close the loop within 48 hours. Contact detractors directly, acknowledge the issue, and explain what you plan to do about it. Companies that follow up with detractors convert 10-15% of them into promoters. Aggregate detractor feedback by theme to identify systemic problems. If 40% of detractors mention onboarding, that is your highest-priority fix.
