What is customer satisfaction score?

Also known as: CSAT

Customer satisfaction score (CSAT) measures how satisfied a customer is with a specific interaction, product, or service, usually by asking them to rate it on a scale of 1 to 5. It is expressed as the percentage of responses that are satisfied — typically the top two ratings.

Formula

How to calculate customer satisfaction score

CSAT = (Satisfied responses ÷ Total responses) × 100
Satisfied responses
Count of responses in the top two boxes — 4 and 5 on a 5-point scale
Total responses
All responses received

Worked example

Of 300 responses, 240 rate 4 or 5. CSAT = (240 ÷ 300) × 100 = 80%.

Benchmarks

In practice

What you need to know about customer satisfaction score

CSAT vs NPS vs CES

CSAT measures satisfaction with a specific interaction and is transactional and immediate. NPS measures overall loyalty and is relational and longitudinal. Customer effort score measures how hard a task was, and tends to predict repeat behavior better than either. They answer different questions, and a team tracking all three without knowing which decision each informs is generating reporting rather than insight.

Scale choice changes the number

A 5-point scale and a 7-point scale produce different CSAT figures for identical underlying sentiment, and the definition of "satisfied" — top box versus top two boxes — shifts it again. Neither is wrong, but comparing your CSAT to an external benchmark computed differently is meaningless. Fix your methodology and compare against yourself.

How to improve it

Improving customer satisfaction score

01

Ask immediately after the interaction

CSAT decays fast as memory fades. Surveys sent days later measure general mood rather than the specific interaction.

02

Keep it to one question

Every additional question measurably reduces completion. If you need more detail, use a single optional free-text follow-up.

FAQ

Customer satisfaction score questions, answered

What is a good CSAT score?+

75–85% is generally good, and B2B SaaS support teams often target 85–90%. Because the figure depends heavily on scale design and on whether you count top-box or top-two-box responses, your own trend is far more meaningful than an external benchmark.

How do you calculate CSAT?+

Divide the number of satisfied responses — conventionally ratings of 4 and 5 on a 5-point scale — by total responses, then multiply by 100. Document whether you use top-box or top-two-box, since the choice materially changes the result.

What is the difference between CSAT and NPS?+

CSAT measures satisfaction with a specific recent interaction and is transactional. NPS measures overall willingness to recommend and is relational. A customer can report high CSAT on every support ticket while being a detractor overall, because the product is not delivering strategic value.
