What Is CSAT? Definition, Formula, and Why It Matters

CSAT (Customer Satisfaction Score) is a metric that measures how satisfied a customer is with a specific interaction, product, or service. It is one of the most widely used customer experience metrics because it is simple to collect, easy to understand, and directly tied to the moments that drive loyalty or churn.

Most teams ask one direct question such as: “How satisfied were you with your experience?” Respondents pick a score — typically 1 to 5 or 1 to 10. You then calculate the percentage of positive responses to get your CSAT score.

The CSAT formula

CSAT (%) = (Satisfied responses ÷ Total responses) × 100

On a 1-5 scale, scores of 4 and 5 are counted as satisfied. On a 1-10 scale, 9 and 10 are typically used. The result is expressed as a percentage. A score of 80% means 80 out of 100 respondents were satisfied.

For a worked example and scale-by-scale breakdown, see How to calculate CSAT.

Why CSAT is useful

• It is easy for customers to answer — one question takes under ten seconds.
• It captures feedback right after key touchpoints, when memory is freshest.
• It helps teams detect service or product issues before they become churn signals.
• It pairs with open comments to explain the score, not just report it.
• It is comparable over time, making trend analysis straightforward.

When to use CSAT

CSAT works best at specific, transactional moments:

• After a support ticket is resolved
• After onboarding or setup is complete
• After an order is delivered or picked up
• After a key product feature is used for the first time
• After a subscription renewal or upgrade

It is less useful as a general “how do you feel about us?” question sent at random intervals. That is better handled by NPS. See CSAT vs NPS vs CES for guidance on when to use each.

What a good CSAT workflow looks like

1. Choose a specific touchpoint (support resolution, onboarding, delivery).
2. Send one rating question immediately after the event.
3. Add one optional open comment field.
4. Segment responses by team, channel, product area, or customer tier.
5. Review trends weekly and route low scores to the responsible team.
6. Close the loop — tell customers when their feedback led to a change.

Common CSAT mistakes to avoid

• Surveying too late: Sending feedback requests hours or days after the event drops response rates and score accuracy.
• Using too many questions: More than two questions in a CSAT survey increases abandonment.
• Ignoring the comments: The score tells you there is a problem; the comment tells you what to fix.
• Chasing a single number: One score in isolation has little meaning. Track direction over time.

Frequently asked questions

What does CSAT stand for? CSAT stands for Customer Satisfaction Score. It is a percentage that represents the share of respondents who rated their experience positively.

What is a good CSAT score? Typical targets range from 75% to 90% depending on industry and touchpoint. Scores above 85% are generally considered strong. For industry-specific ranges, see CSAT benchmarks by industry.

How is CSAT different from NPS? CSAT measures satisfaction after a specific interaction. NPS (Net Promoter Score) measures long-term loyalty and likelihood to recommend. They answer different questions and are best used together. See CSAT vs NPS vs CES.

How often should you measure CSAT? Measure CSAT at every qualifying event (support resolution, order completion, onboarding), not on a fixed calendar schedule. This gives you more data and makes results more actionable.
