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.
NPS Benchmarks by Industry
| Industry | Average NPS | Notes |

| Telecom | 10 – 25 | Consistently the lowest-scoring industry due to contract friction and support issues |
| Insurance | 20 – 40 | Claims experience is the primary score driver |
| Consulting / Professional Services | 40 – 60 | Relationship-driven businesses tend to score well when delivery matches expectations |

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
- 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.
- 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.
- 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.
- 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.
- 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.
