TL;DR
Net Promoter Score (NPS) measures customer loyalty via the question "How likely are you to recommend [product] to a friend or colleague?" on a 0–10 scale. Formula: % Promoters (9–10) − % Detractors (0–6), giving a score from −100 to +100. B2B SaaS best-in-class: 50+; median: 30–50; below 20 indicates product or CS issues (Delighted 2025 NPS Benchmarks).
What is Net Promoter Score?
Net Promoter Score (NPS) is a customer-loyalty metric introduced by Fred Reichheld in a 2003 Harvard Business Review article ("The One Number You Need to Grow"). It asks one question — "On a scale of 0–10, how likely are you to recommend our product to a friend or colleague?" — and segments respondents into Promoters (9–10), Passives (7–8), and Detractors (0–6).
The score is calculated as % Promoters minus % Detractors, giving a single number from −100 (every customer is a Detractor) to +100 (every customer is a Promoter). It is the most widely reported customer-loyalty metric in B2B SaaS and consumer brands — used in board decks, executive reviews, and customer-success forecasts.
NPS is best understood as a directional loyalty signal, not a precise predictor. It correlates with net revenue retention and churn, but the relationship is noisy at the customer-level — a 9 doesn't guarantee renewal, a 4 doesn't guarantee churn. It works best as a cohort-level trend and as a qualitative trigger (a Detractor warrants a CS conversation, not a renewal panic).
Why NPS matters
NPS is universally understood — every executive, board member, and investor knows what it is, which makes it the lingua franca of customer-loyalty reporting. That alone is valuable: it lets cross-functional teams align on customer health without translating between metrics.
For operators, NPS is most useful as a leading indicator of brand strength and word-of-mouth. Companies with NPS above 50 typically see 15–30% of new business come from referrals; companies below 20 see <5%. The metric also surfaces product issues earlier than churn — Detractor verbatims often flag the breakage 3–6 months before it shows up as a renewal loss.
The criticism of NPS — that it doesn't cause retention, it correlates with it — is fair but doesn't make NPS useless. Pair NPS with customer health score (composite) and CSAT (interaction-level) for a complete picture. NPS captures relationship loyalty; CSAT captures interaction satisfaction; health score captures behavioural reality.
NPS formula
Two methodological choices matter: relationship vs. transactional NPS, and the survey cadence. Relationship NPS asks about overall loyalty once or twice a year. Transactional NPS asks about a specific interaction (post-onboarding, post-support ticket). Most teams report relationship NPS; sophisticated teams track both.
NPS = % Promoters − % Detractors Where: - Promoters = respondents scoring 9–10 - Passives = respondents scoring 7–8 (not counted) - Detractors = respondents scoring 0–6 Example: - 1,000 respondents - 520 Promoters (52%) - 280 Passives (28%) - 200 Detractors (20%) NPS = 52 − 20 = +32

Common mistakes
- Ignoring response-rate bias. A 5% response rate skews toward extremes — happy customers and angry ones — and overstates score volatility. Pursue 25%+ response rates via incentives and short surveys, and report response rate alongside the score.
- Reading the number without the verbatims. The score tells you the direction; the open-ended follow-up question ("What is the primary reason for your score?") tells you why. Skipping the verbatims wastes the metric's most useful output.
- Treating Passives as Promoters. A 7 or 8 is not a Promoter — it's a customer who could go either way at renewal. Operators who optimise for "% non-Detractor" miss the most actionable segment.
- Setting NPS as a comp metric for CS teams. When NPS becomes a bonus driver, response rate gaming and customer pressure ("could you give us a 10?") become rampant. Use NPS for diagnosis, not compensation.
- Single-cadence reporting. A quarterly relationship-NPS misses post-incident bumps and onboarding fall-offs. Pair it with transactional NPS after key moments (onboarding, expansion, support resolution).
Related metrics
NPS sits inside the customer-loyalty metric stack alongside CSAT (interaction satisfaction), CES (effort-based loyalty), and customer health score (composite, behavioural). Retention outcomes: churn rate, gross retention, and NRR. For B2B specifically, pair NPS with land-and-expand expansion velocity to validate that loyalty signal translates to revenue growth.

Frequently asked questions
What is a good NPS score?
For B2B SaaS, 50+ is best-in-class, 30–50 is median, and below 20 indicates product or CS issues. For ecommerce, 40+ is healthy. The right benchmark depends heavily on industry — telecoms run 0–20 and that's normal; consumer subscriptions run 50+ and below 30 is a warning sign. Always benchmark within your category.
What's the difference between NPS, CSAT, and CES?
NPS asks about likelihood to recommend (relationship loyalty). CSAT asks about satisfaction with a specific interaction (e.g., a support ticket, an onboarding step). CES asks how much effort the customer had to put in. NPS is best for executive reporting; CSAT for support quality; CES predicts retention better than the other two for transactional products.
How often should you measure NPS?
Relationship NPS once or twice per year (annual or semi-annual). Transactional NPS triggered by specific events — post-onboarding, post-support ticket, post-expansion. Monthly relationship NPS is too frequent and produces noisy data without enough signal change to act on.
Is NPS still relevant in 2026?
Yes, but with caveats. NPS is a useful directional signal and remains the lingua franca of customer-loyalty reporting. It is not, however, a precise predictor of churn or revenue. Modern CS orgs pair NPS with composite customer health scores (which incorporate behaviour, not just self-report) for actionable account-level decisions.
Why do you exclude Passives in NPS?
Passives (scores 7–8) are excluded by design — Reichheld's original research found that only customers scoring 9 or 10 reliably refer new business, and customers scoring 0–6 actively warn others away. The 7–8 range represents satisfied customers who don't strongly advocate, so they aren't counted as drivers in either direction.
