Net Promoter Score (NPS)
Net Promoter Score (NPS) is a customer loyalty metric calculated by asking customers how likely they are to recommend a business on a scale of 0 to 10. Respondents are categorized as Promoters (9-10), Passives (7-8), or Detractors (0-6). The NPS is calculated by subtracting the percentage of Detractors from the percentage of Promoters, yielding a score between -100 and +100.
Key Statistics
Companies with an NPS above 50 grow at 2x the rate of those with average scores (Bain & Company).
A 7-point increase in NPS correlates with a 1% increase in revenue growth (London School of Economics).
Only 5% of dissatisfied customers actually complain — NPS captures the silent majority (TARP Research).
Why It Matters
NPS is one of the most widely used benchmarks for customer satisfaction and loyalty. A high NPS correlates with organic growth through word-of-mouth referrals, while a declining NPS signals customer experience issues that need your immediate attention. Tracking NPS over time reveals whether your operational changes are improving or harming customer relationships.
Real-World Examples
A fitness chain tracked NPS by location and discovered one gym scored 15 while others averaged 55. Investigation revealed a staffing issue unique to that location, and after addressing it, NPS climbed to 48 within three months.
An online retailer with an NPS of 72 correlated their promoter segment with review behavior and found that 60% of promoters had also left a public 5-star review, validating the link between NPS and organic advocacy.
Best Practices
Survey customers at consistent touchpoints — after purchase, after support interactions, or at regular intervals — to get comparable data over time.
Follow up with detractors within 48 hours to understand their specific concerns and attempt recovery.
Segment NPS by customer cohort, location, or product line to identify specific areas needing improvement.
Combine NPS with qualitative review data for a complete picture — the score tells you how many are unhappy, reviews tell you why.
Common Mistakes
Obsessing over the NPS number rather than analyzing the reasons behind promoter and detractor scores.
Surveying too frequently, which causes survey fatigue and reduces response rates and data quality.
Only acting on detractor feedback while ignoring passive scores (7-8), which represent the largest improvement opportunity.

Frequently Asked Questions
An NPS above 0 means you have more promoters than detractors. Scores above 30 are considered good, above 50 is excellent, and above 70 is exceptional. However, benchmarks vary significantly by industry, so compare against your direct competitors.
NPS measures likelihood to recommend on a 0-10 scale and produces a single composite score. Star ratings measure satisfaction on a 1-5 scale for individual transactions. NPS better predicts long-term loyalty, while star ratings reflect immediate experience quality.
A minimum of 100 responses per measurement period provides a statistically reliable NPS. For businesses with smaller customer bases, aim for at least a 30% response rate. Lower sample sizes increase the margin of error, making trends less reliable.
Both have value. Transactional NPS measures satisfaction with a specific interaction and helps identify process issues. Relationship NPS measures overall loyalty and is better for strategic planning. Most businesses benefit from running both in parallel.
