Net Promoter Score (NPS)
Net Promoter Score (NPS) is a customer loyalty metric derived from a single survey question: 'On a scale of 0 to 10, how likely are you to recommend this company (or product/service) to a friend or colleague?' Respondents are bucketed into Promoters (9-10), Passives (7-8), and Detractors (0-6). NPS = percentage of Promoters minus percentage of Detractors, yielding a score from -100 to +100. Scores above 0 are generally considered acceptable, above 50 excellent, and above 70 world-class. NPS is most useful as a trend metric tracked over time and broken out by customer segment, product line, or geography rather than as a single point-in-time number.
Problem & Application
A campground reservation platform surveys 500 guests after checkout. 200 score 9-10 (Promoters, 40%), 150 score 7-8 (Passives, 30%), and 150 score 0-6 (Detractors, 30%). NPS = 40 - 30 = +10. A competitor in the same market scores +45. The gap signals a meaningful loyalty deficit. Breaking down the Detractor responses reveals that late check-in communication and site cleanliness drive most low scores -- actionable issues distinct from pricing complaints. For SaaS companies, NPS by pricing tier often reveals that enterprise customers are Promoters while SMB customers churn faster -- driving segmented roadmap investment decisions. Importantly, NPS alone does not explain the 'why.' Pairing it with follow-up open-text questions and correlating NPS cohorts with actual retention and lifetime value data converts a soft sentiment metric into a hard financial planning input.
In Short
NPS is a valuable tool for understanding customer loyalty, and improving it can lead to higher retention, repeat business, and referrals.
How it works
The arithmetic ignores Passives entirely: you subtract the percentage of Detractors from the percentage of Promoters, so a business can lift its score either by converting Detractors upward or by turning Passives into Promoters. Beyond the boardroom number, operators use NPS to flag at-risk accounts (any Detractor triggers a follow-up call) and to forecast referral-driven growth, since Promoters are the people most likely to send word-of-mouth bookings. The most common misunderstanding is treating NPS as a percentage or an average score; it is a net difference between two groups, which is why a +30 and a -30 can both arise from very different distributions of responses.
Calculating NPS for a multi-property RV resort group
A regional operator running four RV resorts emails a post-stay survey to 1,200 guests over a season and receives 600 responses. Of those, 330 score 9-10 (Promoters), 150 score 7-8 (Passives), and 120 score 0-6 (Detractors). Convert each bucket to a percentage of total responses: Promoters = 330 / 600 = 55%, Detractors = 120 / 600 = 20%. NPS = 55 - 20 = +35. The 25% Passives drop out of the formula but represent the biggest upside; nudging even a third of them to 9-10 would push the score toward +43. Segmenting by property shows the newest resort scoring +12 while the flagship scores +52, isolating where operational fixes (slow check-in, weak Wi-Fi) will move the needle. Tracked season over season, that property-level breakout tells the owner whether capital improvements are actually translating into guest loyalty.
Frequently asked
What is a good NPS score?
Any score above 0 means you have more Promoters than Detractors. As a rough rule of thumb, above 20 is favorable, above 50 is excellent, and above 70 is world-class. Benchmarks vary widely by industry, though, so comparing against direct competitors and tracking your own trend over time matters more than the absolute number.
How is NPS calculated?
Survey customers on a 0-10 likelihood-to-recommend scale, then sort responses into Promoters (9-10), Passives (7-8), and Detractors (0-6). Calculate the percentage of total respondents in each group and subtract the Detractor percentage from the Promoter percentage. Passives are not added in. The result ranges from -100 to +100.
What is the difference between NPS and customer satisfaction (CSAT)?
CSAT measures satisfaction with a specific interaction or transaction, usually rated 1-5 and reported as a percentage of positive responses. NPS measures broader loyalty and likelihood to recommend the overall brand. CSAT is best for pinpointing a single touchpoint, while NPS gauges long-term relationship strength and referral potential.
