How to use the customer effort score calculator
Customer Effort Score (CES) measures how much work a customer had to do, usually with a single question such as "how easy was it to handle your request?". Enter how many people gave each score and this calculator returns the average, the low- and high-effort shares, and a 0β100 ease index.
The part that most often goes wrong is the scale and its direction. Some teams use 1β5, others 1β7, and a high score can mean either easy or hard depending on the wording. You pick both here, and the values you picked are printed back into the result labels so the basis of the calculation is visible on screen.
An average alone hides movement, because very easy and very hard replies offset each other. The tool therefore reports the share of the two easiest scores and the two hardest scores separately, and names those score numbers in the label so there is no doubt about what was grouped.
No "good CES" threshold is offered, because scores from different scales and different question wordings are not comparable in the first place. Enter your own target average instead and the gap is shown; tracking the same question on the same scale over time is the most reliable reading.
Frequently Asked Questions
There is no agreed benchmark. Scale (1β5 or 1β7), question wording, and survey timing differ between companies, so another companyβs number is not comparable. This tool asserts no benchmark and lets you enter your own target instead.
Look at both. Averages hide movement because very easy and very hard answers cancel out. The low-effort and high-effort shares show whether the group that struggled actually got smaller.
Depending on the wording, a high score can mean easy or hard. Get the direction wrong and the same average reads the opposite way, so the labels name which scores were counted as low effort under the direction you chose.
