What is Net Promoter Score (NPS)?

Net Promoter Score (NPS)

Net Promoter Score (NPS) is a customer-satisfaction metric based on a single survey question: ‘How likely are you to recommend us to a friend or colleague?’ on a 0-to-10 scale. Respondents scoring 9–10 are Promoters; 7–8 are Passives; 0–6 are Detractors. NPS = percentage of Promoters minus percentage of Detractors. Introduced by Fred Reichheld in 2003, NPS has become the most widely-used customer-satisfaction benchmark despite ongoing criticism of its statistical properties.

NPS score interpretation

Rough ranges:

Below 0. More Detractors than Promoters. Significant customer-experience problems.

0–30. Typical for most businesses. Room to improve.

30–50. Good. Majority of Promoters.

50–70. Very strong. Top-quartile.

70+. Exceptional. Brands with deep customer loyalty (Apple in its prime, Tesla at various points) hit these numbers.

NPS varies substantially by industry. B2B software often runs higher than consumer retail; insurance and utilities often lower.

Why NPS is popular

Four reasons:

Simple to administer. One question, one scale. Lower friction than longer surveys.

Standardised for benchmarking. Same question across industries allows rough comparison.

Correlates with loyalty and growth. High-NPS companies grow faster on average. The correlation is real even if noisy.

Tracked over time. Trend data is more valuable than absolute values. NPS trends inside a business tell a consistent story.

NPS criticism

Four recurring concerns:

Statistical properties are weak. The 0–10 scale, promoter/detractor cutoffs, and subtraction formula are not particularly defensible from a measurement-theory perspective.

Biased samples. Satisfied and angry customers respond more than neutral ones. Response bias can distort the score.

Gaming pressure. Organisations whose compensation depends on NPS find ways to inflate it (survey timing, question framing, who receives surveys).

Correlation, not causation. High NPS correlates with growth, but causation direction isn’t always clear. Great products get high NPS and grow; NPS isn’t the mechanism.

How to use NPS well

Five disciplines:

Track trend, not absolute. Your NPS trend over time matters more than the absolute number. Compare to yourself.

Always ask follow-up. ‘Why did you give that score?’ open-text response is where the actual insight is. The number is a sorting mechanism.

Segment by customer type. Enterprise NPS, SMB NPS, power-user NPS. Aggregated NPS hides patterns.

Close the loop with detractors. Detractors are telling you what’s broken. Responding and fixing is more valuable than the score itself.

Pair with behavioural data. High NPS + churning customers suggests NPS measurement issues. Check NPS against retention to validate.

Relational vs transactional NPS

Two common variants:

Relational NPS. Asked periodically (quarterly, annually) about overall relationship. Measures long-term loyalty.

Transactional NPS. Asked after specific interactions (support ticket closed, product launch attended). Measures touchpoint-specific satisfaction.

Both are useful; they answer different questions. Many teams run both.

NPS in organisational decision-making

Three common uses:

Executive dashboard inclusion. NPS as one metric in board materials. Signals customer health.

Functional-team KPI. Customer-success, support, product often have NPS targets.

Voice-of-customer programme driver. NPS survey responses feed qualitative research and product decisions.

Alternatives and supplements to NPS

Four metrics sometimes used alongside or instead:

Customer Satisfaction (CSAT). ‘How satisfied were you?’ on a simpler scale. Often more transaction-specific.

Customer Effort Score (CES). ‘How much effort did it take to get your outcome?’ Predicts retention better than NPS in some research.

Retention rate. Ultimate behavioural measure. Customers stay or leave.

Product-usage metrics. Deep engagement is often a better loyalty predictor than stated satisfaction.

NPS in content programmes

Three applications:

Content satisfaction measurement. Asking NPS on content specifically (newsletter, blog) rather than on the overall product.

Customer feedback for content planning. NPS follow-up comments often surface content topics customers care about.

Advocacy identification. Promoters are your referral candidates, review-writers, and case-study prospects.

We built Penfriend to help with the content end of customer-success programmes - the pre-purchase content that sets accurate expectations, the onboarding content that drives activation, the ongoing content that reinforces product value. These content categories correlate with higher NPS because they produce a better customer experience. The feedback loop works both directions: content affects NPS; NPS feedback informs content.
