What is the difference between NPS and CSAT?
NPS (Net Promoter Score) measures long-term loyalty by asking how likely you are to recommend a company (0-10 scale, reported −100 to +100). CSAT (Customer Satisfaction Score) measures satisfaction with one specific interaction (typically 1-5, reported as a percentage). NPS gauges the overall RELATIONSHIP; CSAT gauges a single TRANSACTION.
The full answer
Relationship vs transaction
NPS and CSAT both survey customers, but they answer different questions over different time horizons. NPS asks about loyalty to the whole company ("How likely are you to recommend us?"). CSAT asks how a SPECIFIC moment went ("How satisfied were you with this support chat / this purchase / this onboarding?"). NPS is relational and long-term; CSAT is transactional and immediate.
Side-by-side comparison
| Property | NPS | CSAT |
|---|---|---|
| Question | "How likely to recommend?" | "How satisfied with [X]?" |
| Scale | 0-10 | Typically 1-5 (sometimes 1-7) |
| Score range | −100 to +100 | 0% to 100% |
| Measures | Long-term loyalty / relationship | Short-term satisfaction / one interaction |
| Timing | Periodic (quarterly, relational) | Right after an interaction (transactional) |
| Calculation | % Promoters − % Detractors | % positive responses ÷ total |
| Predicts | Growth, referral, retention | Interaction quality, immediate friction |
How each is calculated
NPS: ask "On a 0-10 scale, how likely are you to recommend us to a friend or colleague?" Scores of 9-10 are Promoters, 7-8 are Passives (ignored in the math), 0-6 are Detractors. NPS = %Promoters − %Detractors, producing a result from −100 (everyone a detractor) to +100 (everyone a promoter). Above 0 is "good," above 50 is "excellent," above 70 is "world-class" per Bain benchmarks.
CSAT: ask "How satisfied were you with [specific interaction]?" on a 1-5 scale. CSAT % = (responses of 4 or 5) ÷ (total responses) × 100. A CSAT of 80% means 80% of respondents were satisfied or very satisfied. There is no negative range.
When to use which
- Use CSAT to measure a specific touchpoint: support tickets, post-purchase, onboarding completion, feature usage. It is immediate and pinpoints WHERE friction lives.
- Use NPS to measure the overall health of the customer relationship over time. It correlates with referral behavior and growth — the basis of Fred Reichheld's "The One Number You Need to Grow" (HBR, 2003).
The third sibling: CES
A common companion is Customer Effort Score (CES): "How easy was it to get your issue resolved?" CES, from Gartner/CEB's "The Effortless Experience," predicts loyalty better than CSAT for SERVICE interactions specifically — because reducing effort drives repeat business more than delight does. Many teams run CSAT + CES on support and NPS on the relationship.
Why not just use one?
They answer different questions. A customer can rate a support chat 5/5 (high CSAT) yet still be a Detractor on NPS because the product is too expensive or missing a feature — the interaction was great, the relationship is not. Conversely, a Promoter might rate one slow support ticket 2/5. Tracking both catches both failure modes: relationship erosion (NPS) and interaction friction (CSAT).
Benchmarks (directional)
- NPS: SaaS median ~30-40; top quartile 50+; consumer brands vary widely (some premium brands ~60, airlines often under 20).
- CSAT: 75-85% is typical "good"; world-class support orgs sustain 90%+.
- The American Customer Satisfaction Index (ACSI) tracks national CSAT by industry as a 0-100 academic index — a useful external benchmark.

Time ranges by condition
| Condition | Duration | Note |
|---|---|---|
| NPS scale | 0-10 question → −100 to +100 score | — |
| CSAT scale | 1-5 question → 0 to 100% score | — |
| NPS quality bands (Bain) | good >0 · excellent >50 · world-class >70 | — |
| CSAT quality bands | good 75-85% · world-class 90%+ | — |
| NPS segments | Promoter 9-10 · Passive 7-8 · Detractor 0-6 | — |
What changes the time
- Time horizon. NPS is relational/long-term; CSAT is transactional/immediate
- What is measured. NPS = likelihood to recommend (loyalty); CSAT = satisfaction with one interaction
- Scale + range. NPS 0-10 maps to −100..+100; CSAT 1-5 maps to 0..100%
- Survey timing. NPS is sent periodically; CSAT is sent right after a specific interaction
Common questions
Is NPS better than CSAT?
Neither is "better" — they measure different things. NPS measures long-term loyalty and predicts referral and growth; CSAT measures satisfaction with one specific interaction and pinpoints friction. Use CSAT to improve touchpoints like support and onboarding, and NPS to track the overall relationship. Most mature teams run both.
Can a customer have high CSAT but low NPS?
Yes, and it is common. Someone can rate a support chat 5/5 (high CSAT) but still be an NPS Detractor because the product is too expensive or missing features — the interaction was great, the relationship is not. The reverse happens too. Tracking both metrics catches relationship erosion and interaction friction separately.
How is NPS calculated?
Ask "0-10, how likely are you to recommend us?" Promoters score 9-10, Passives 7-8 (ignored), Detractors 0-6. NPS = %Promoters − %Detractors, producing a score from −100 to +100. Passives count toward the total response base but not the subtraction, which is why adding neutral responses lowers the score.
What is CES and how does it relate?
Customer Effort Score (CES) asks "how easy was it to resolve your issue?" From Gartner/CEB's "The Effortless Experience," CES predicts loyalty better than CSAT for SERVICE interactions because reducing effort drives repeat business more than delight. Many teams pair CES + CSAT on support and NPS on the relationship.
