What is Customer Effort Score?
Customer Effort Score, or CES, measures how much work someone had to do to get something done. You ask a version of “how easy was it to do X?” and they answer on a scale.
It came out of research finding that reducing effort keeps customers better than exceeding expectations does. People rarely leave because you failed to delight them. They leave because something was harder than it needed to be, repeatedly.
How CES is calculated
CES = sum of all responses Ă· number of responses
The usual scale is one to seven, where seven is very easy, and the score is the average. Some teams use a five-point scale, and some report the percentage of respondents choosing the top two options, which is closer to how CSAT works.
All three are valid. Mixing them across quarters is not, because the numbers stop being comparable.
What is a good CES score?
On a seven-point scale, above 5 is generally treated as good and above 6 as strong. As with every experience metric, the useful comparison is your own previous measurement on the same question and the same audience.
What matters more than the absolute number is which touchpoints score worse than the others. A CES of 5.2 overall is not a finding. A CES of 5.2 overall with 3.4 on the cancellation flow is.
When to ask for CES
Immediately after the task, while the effort is still fresh. The usual moments are after a support interaction, after onboarding, after a self-service task like changing a plan, and after anything that involves a form.
Asking later produces a general impression rather than a measurement of the thing you wanted to measure.
CES vs CSAT vs NPS
All three ask a customer to rate something and they answer different questions.
- CES asks how hard it was. Best predictor of whether someone stays.
- CSAT asks how satisfied they were. Good for spotting a broken step.
- NPS asks whether they would recommend you. Good as a slow relationship measure.
CES is the one most teams under-use, partly because a high-effort experience does not generate complaints. People just quietly do less.
How to reduce customer effort
Find the steps people repeat. Repetition is the clearest effort signal there is. Anyone doing something three times is telling you it did not work the first two.
Remove the handoffs. Every transfer between channels, teams or tools adds effort the customer pays for.
Answer the next question before it is asked. Most follow-up contacts are predictable from the first one.
Ask why, not just how much. A low CES score with no comment tells you where to look and nothing about what to change.
Measuring CES with Usersnap
CES runs as a micro-survey at the end of the task you want to measure, inside the product rather than in a separate email. The free-text follow-up arrives with the score, and AI-powered automations group those comments by topic so the source of the effort is visible without reading every response individually. Scores and comments sit alongside bug reports and feature requests, which matters because high effort is often caused by something already reported as a bug.
CES FAQ
How is Customer Effort Score calculated?
Add all responses and divide by the number of responses, giving an average on whatever scale you used. Some teams instead report the percentage choosing the top two options.
What is a good CES score?
On a seven-point scale, above 5 is generally good and above 6 strong. Your own trend on the same question matters more than the benchmark.
What is the difference between CES and CSAT?
CES measures how much effort something took. CSAT measures how satisfied someone was with it. A task can be satisfying and still exhausting, and the effort is what predicts churn.
When should you send a CES survey?
Straight after the task, while the person still remembers what it took.
