Calculate Net Promoter Score from survey data. Analyze promoter, passive, and detractor distributions with benchmarks and improvement modeling.
Net Promoter Score (NPS) is the most widely used measure of customer loyalty and satisfaction. It's based on a single question: "On a scale of 0–10, how likely are you to recommend [product/company] to a friend or colleague?" Respondents are grouped into three categories: Promoters (9–10), Passives (7–8), and Detractors (0–6). NPS equals the percentage of Promoters minus the percentage of Detractors.
NPS ranges from −100 (everyone is a detractor) to +100 (everyone is a promoter). Scores above 0 are positive, above 30 are good, above 50 are excellent, and above 70 are world-class. While NPS has its critics, it remains the most benchmarkable measure of customer sentiment available, with published benchmarks for nearly every industry.
This calculator takes your survey responses (either raw counts per score 0–10 or aggregated promoter/passive/detractor counts), computes your NPS, visualizes the score distribution, benchmarks against industry standards, and models the impact of converting detractors or passives to promoters.
NPS is the universal language of customer sentiment. This calculator instantly computes your score, shows the full distribution of responses, and benchmarks against industry leaders. The improvement modeling shows exactly how many detractors you need to convert (and to what level) to reach your target NPS. Use it for quarterly tracking, competitive benchmarking, and setting customer experience goals.
Net Promoter Score = % Promoters − % Detractors Promoters: scored 9 or 10 Passives: scored 7 or 8 Detractors: scored 0 through 6 NPS ranges from −100 to +100
Result: NPS = +31
With 350 total responses: 180 Promoters (51.4%), 100 Passives (28.6%), and 70 Detractors (20.0%). NPS = 51.4% − 20.0% = +31.4, rounded to +31. This is a good score, above the average for most B2B SaaS companies. Converting just 15 Detractors to Passives would push NPS to +40.
The raw NPS number hides important nuances. Two companies can both have NPS of +30 with very different distributions: one might have 50% Promoters and 20% Detractors (healthy), while another has 35% Promoters and 5% Detractors (also healthy but less polarizing). The shape of the distribution tells you about customer experience consistency and the nature of your customer relationships.
Each Detractor converted to a Passive improves NPS by approximately (1/N × 100) points, where N is total responses. Each Passive converted to a Promoter also improves by the same amount. But the strategic value differs: reducing Detractors eliminates negative word-of-mouth and churn risk, while creating Promoters drives referrals and organic growth. Prioritize reducing Detractors first.
NPS benchmarks vary significantly by industry. Technology/SaaS companies average 30–40. Banking averages 20–35. Healthcare averages 25–45. Airlines average 15–30. Retail averages 40–65. Always compare your NPS against industry-specific benchmarks rather than absolute numbers to understand your relative competitive position.
NPS above 0 is positive (more promoters than detractors). Above 30 is good. Above 50 is excellent. Above 70 is world-class. Industry context matters: B2B SaaS averages around 30–40, while consumer products vary widely. Compare against your specific industry benchmarks rather than absolute numbers.
Users scoring 7–8 are satisfied but not enthusiastic. Research shows they're unlikely to actively recommend your product and are vulnerable to competitor offers. They're "passively satisfied" rather than loyal advocates. True advocacy (word-of-mouth, referrals) comes overwhelmingly from 9–10 respondents.
Most companies survey NPS quarterly. Some use "transactional NPS" triggered by specific interactions (support tickets, feature launches). Avoid surveying too frequently (monthly fatigue) or too rarely (miss trends). Quarterly relationship NPS combined with event-triggered transactional NPS provides the best signal.
Bain & Company's research shows correlation between industry-leading NPS and revenue growth. Promoters have higher retention, larger contract values, and generate referrals. However, NPS alone doesn't guarantee growth — product-market fit, pricing, and market timing matter too. NPS is one signal among several.
While Passives don't directly affect the NPS formula, they're your biggest opportunity. They're already somewhat satisfied; understanding what would make them Promoters is often easier than converting Detractors. Small improvements that move Passives to Promoters have an outsized effect on NPS.
They measure different things. NPS measures loyalty and likelihood to recommend. CSAT (Customer Satisfaction Score) measures satisfaction with a specific interaction. CES (Customer Effort Score) measures ease of use. NPS is best for strategic tracking and benchmarking. CSAT and CES are better for specific interaction optimization.
Common mistakes include surveying too narrow a sample (only happy users), survey fatigue from over-surveying, ignoring qualitative follow-up data, comparing NPS across wildly different industries, and using NPS as the sole metric for customer health. NPS is most valuable as part of a broader customer sentiment framework.
