Net Promoter Score (NPS)
Net Promoter Score (NPS) is the customer loyalty metric calculated by subtracting the percentage of Detractors from the percentage of Promoters. Customers answer a single question, "How likely are you to recommend this product/company to a friend or colleague on a 0-10 scale?", with Promoters scoring 9-10 and Detractors scoring 0-6. The resulting number ranges from -100 to +100 and is used as the headline metric for customer loyalty and satisfaction. Developed by Fred Reichheld at Bain & Company in 2003, NPS has become one of the most-used (and most-criticized) customer metrics in business.
The math:
NPS = % Promoters (9-10) - % Detractors (0-6)
Passives (7-8) are excluded from the calculation but represent customers who are satisfied-but-not-enthusiastic.
| Response distribution | Promoters | Passives | Detractors | NPS |
|---|---|---|---|---|
| 50/30/20 | 50% | 30% | 20% | +30 |
| 60/30/10 | 60% | 30% | 10% | +50 |
| 30/30/40 | 30% | 30% | 40% | -10 |
| 80/15/5 | 80% | 15% | 5% | +75 |
NPS benchmarks by industry (2025 data):
| Industry | Median NPS | World-class NPS |
|---|---|---|
| Consumer tech (Apple, Tesla) | +50 to +70 | +70+ |
| SaaS (enterprise) | +30 to +50 | +60+ |
| SaaS (SMB) | +20 to +40 | +50+ |
| Financial services | +10 to +30 | +50+ |
| Telecom | -10 to +20 | +30+ |
| Cable/internet providers | -30 to +10 | +20+ |
What NPS actually measures (and what it doesn't):
What it measures: aggregate customer sentiment at a moment in time. Loosely correlates with retention and word-of-mouth growth.
What it doesn't measure: actual referral behavior (people who say "10" don't always refer), churn risk (a "6" can churn or stay forever), feature satisfaction (the score is global, not specific).
The criticism: NPS is too crude for product decisions. A +50 NPS doesn't tell you what to improve. Detailed feedback (open-text comments, follow-up questions) is where the actionable value lives.
The defense: NPS works as a directional indicator. Tracking NPS over time reveals trends. Comparing NPS across segments (enterprise vs SMB, by tenure cohort) reveals segment-specific issues.
How to use NPS well:
Track trends, not absolute number: NPS comparison across companies is misleading due to industry, survey methodology, and sampling biases. Tracking your own NPS over time is meaningful.
Segment NPS: tenure cohorts (0-3 months, 3-12 months, 12+ months), customer size, product line, geography. Segment NPS reveals more than aggregate NPS.
Follow up on Detractors: every 0-6 should trigger a CSM outreach to understand the issue. Detractor recovery is a real activity.
Survey at meaningful moments: post-onboarding (30 days), post-renewal, post-major-feature-adoption. Random NPS surveys produce noise.
Pair with open-text: "Why?" question after the 0-10 score produces the actionable insights.
Ryan's Take
NPS is the most-cited and most-abused customer metric there is. The trend line is useful. The absolute number is mostly theater. Track it by segment over time, call every Detractor personally, and pair it with open-text feedback that actually moves the roadmap. Putting 'NPS of 50!' on a slide with no methodology or sample size fools no one, and since world-class consumer brands hit +70 while enterprise SaaS at +50 is excellent, comparing your score across industries tells you nothing.
What founders get wrong: Treating NPS as a number to optimize rather than a signal to investigate. A founder sees NPS drop from +45 to +35 and panics, when the real value is investigating what changed (new customer cohort? recent product change? specific segment regression?). The right discipline: use NPS as the trigger for investigation, not the answer to satisfaction.

FAQ
What is Net Promoter Score (NPS)?
A customer loyalty metric measured by asking "How likely are you to recommend us on a 0-10 scale?" then subtracting % Detractors (0-6) from % Promoters (9-10). Result ranges from -100 to +100.
What's a good NPS score?
Depends heavily on industry. Consumer tech (Apple, Tesla): +50-+70. Enterprise SaaS: +30-+50. SMB SaaS: +20-+40. Financial services: +10-+30. World-class is industry-specific.
Why is NPS criticized?
The score is global, not specific (doesn't tell you what to improve). Doesn't measure actual referral behavior. Comparing across industries is misleading. Best used as directional indicator + open-text feedback, not as the answer.
How should I use NPS?
Track trends over time (not absolute number); segment by tenure cohort, customer size, product; follow up personally on every Detractor; pair with open-text "Why?" feedback; survey at meaningful moments (post-onboarding, post-renewal).
