How CSAT is calculated

Customers answer one question — usually how satisfied were you with…? — on a scale from 1 to 5. Your CSAT is the share of people who chose 4 or 5, the two “satisfied” answers:

CSAT = (number of 4s and 5s ÷ total responses) × 100

So 120 satisfied answers out of 160 responses is a CSAT of 75%. The average rating is shown as well, but most teams track the percentage: it's easier to explain and harder to skew with a few extreme answers.

What's a good CSAT score?

It depends heavily on your industry and on when you ask. As a loose guide, scores above 80% are generally seen as good — but the number that matters most is your own trend from one survey to the next.

Ask the same question, the same way, at the same moment (for example straight after a support ticket closes), and compare month to month. Then read the comments from people who gave 1 or 2: they tell you what to fix.

Need questions to go with it? Here are ready-written customer satisfaction survey questions.

Common questions

What's the difference between CSAT and NPS?
CSAT measures how satisfied someone was with one experience — a purchase, a support call. NPS asks how likely they are to recommend you, which measures loyalty to the business overall. Many teams use CSAT after interactions and NPS once a quarter.
My survey uses a 1–10 or 1–7 scale. Does this work?
This calculator is for the standard 1–5 scale. For other scales the same idea applies: count the top answers (for example 6–7 on a 7-point scale) as satisfied and divide by the total.
Is what I type sent anywhere?
No. The calculation happens in your browser, and nothing you enter leaves your device.
