NPS vs CSAT: which to use and when
NPS and CSAT measure different things — and they work best together. See the practical differences and discover which to use at each moment.
What NPS is (short version)
NPS (Net Promoter Score) measures overall customer loyalty with a single question: "On a scale of 0 to 10, how likely are you to recommend our company to a friend?". The calculation is the difference between the percentage of promoters (9–10) and detractors (0–6). It's a top-line, strategic metric used to track base health over time.
What CSAT is (short version)
CSAT (Customer Satisfaction Score) measures point-in-time satisfaction after a specific interaction — a support ticket, a purchase, a delivery. The typical question is "How satisfied were you with [interaction]?" on a 1–5 scale. It's an operational, tactical metric used to evaluate processes and teams.
Side-by-side comparison
The two measure different angles of the experience. NPS focuses on loyalty and intent to recommend; CSAT focuses on satisfaction with a specific moment. NPS is more strategic and less sensitive to daily swings; CSAT is more immediate and helps spot bottlenecks quickly.
- ✓Focus — NPS: loyalty and recommendation · CSAT: interaction satisfaction
- ✓Scale — NPS: 0 to 10 · CSAT: 1 to 5 or % satisfied
- ✓Calculation — NPS: % promoters − % detractors · CSAT: average or % top-2
- ✓Moment — NPS: relational or post-event · CSAT: right after the interaction
- ✓Use — NPS: executive view · CSAT: operational view
Can you use both together?
Yes — and most mature CX companies do. The most common combination is: CSAT after each interaction (support, sales, purchase) to measure operational quality in real time, and relational NPS quarterly or semi-annually to track overall base health. Together they give the full picture: CSAT shows where to improve in the short term, NPS shows whether those improvements are turning into loyalty.
What about CES?
A third metric completes the picture: CES (Customer Effort Score) measures how much effort the customer spent to solve something. The question is like "How easy was it to resolve your issue today?". While CSAT measures satisfaction and NPS measures loyalty, CES measures friction. Used together, the three give the most complete view of customer experience.
Frequently asked questions
NPS or CSAT: which is better?
Neither is "better" — they're complementary. If you have to pick one, NPS is better for long-term strategic view; CSAT is better for immediate operational evaluation. Ideally, use both.
Can I send both surveys to the same customer?
Yes, with different frequencies. CSAT can go out after every interaction (support, purchase). Relational NPS should go out much less often — quarterly or semi-annually — to avoid fatigue.
Which has the higher response rate?
Usually CSAT — because it's tied to a recent interaction and the respondent knows exactly what they're rating. Relational NPS has lower response rates but captures overall loyalty. WhatsApp delivery boosts response rate on both.
Does WiseData NPS also send CSAT surveys?
