How it's calculated

CSAT score
CSAT = (responses rated 4 + responses rated 5) / total responses x 100
Average rating
Average = sum of (rating x count) / total responses
Customer effort score
CES = sum of (rating x count) / total responses, on a 1 to 7 scale
Example: 80 satisfied responses out of 100 is a CSAT of 80%.
Worked examples

CSAT and CES calculation examples

Four survey results worked through, including why the headline score is not the whole story.

Post-chat survey

100 responses to "How satisfied were you with this conversation?"

Ratings 1 to 5: 5, 5, 10, 30, 50.

30 + 50 = 80 satisfied responses out of 100, a CSAT score of 80%. The average rating is 4.15 out of 5.

Satisfied and total

Your helpdesk only reports the headline counts.

412 satisfied responses out of 500.

412 / 500 x 100 = a CSAT score of 82.4%.

Same CSAT, different story

Two teams that both score 80%.

Team A: 0, 10, 10, 80, 0. Team B: 10, 5, 5, 10, 70.

Both are 80% CSAT, but Team B has 10% of customers at "very unsatisfied" and Team A has none. Always look at the spread, not just the headline score.

Customer effort score

100 responses on a 1 to 7 scale, where 7 means very easy.

Ratings 1 to 7: 2, 3, 5, 10, 20, 30, 30.

The average is 5.53 out of 7. 80% found it easy (5 to 7) and 10% found it hard (1 to 3).

Benchmarks

How to read your CSAT and CES

General rules of thumb. Your industry, survey timing and channel all shift what a typical score looks like.

01

80% CSAT and above is strong

Most support teams land somewhere between 70% and 85%. Scoring above 80% consistently is a good sign as a general rule of thumb.

02

Below 70% deserves a closer look

Read the comments on the 1 and 2 ratings first. Low scores usually cluster around a few specific problems, like slow first replies or one confusing policy.

03

CES of 5.5 or higher means low effort

On a 1 to 7 scale where 7 is very easy, an average above 5.5 suggests customers rarely struggle. Below 4.5 points to friction worth fixing.

04

Compare like with like

CSAT varies with survey timing, wording and channel. Track your own score over time and compare teams using the same survey, not against someone else's number.
