Customer Effort Score

In depth

Customer effort score (CES) is a survey metric that captures how easy, or how hard, it was for a customer to get their issue resolved. The idea behind it is simple but powerful: customers rarely reward you for a smooth experience, but they punish a difficult one, so the effort they had to spend is a sharper predictor of loyalty than a general satisfaction rating.

It is measured with a single question asked just after an interaction, most often a statement the customer agrees or disagrees with, such as "the company made it easy to handle my issue", rated on a scale. The score is then the average of all those ratings: sum the effort ratings and divide by the number of responses. On the widely used seven-point agreement scale, a higher average means lower effort, which is the good direction.

That last point trips people up, so it is worth stating plainly. Older versions of CES asked customers to rate the effort itself, where a high number meant more effort and was therefore bad. Most teams now use the agreement-scale version, where a high number means the customer agreed it was easy, and is good. Whichever you pick, label it clearly so nobody reads the trend upside down.

How the survey works

CES is deliberately lightweight. One question, asked at the moment the experience is fresh, typically right after a support chat, a checkout, or a self-service session. Because it asks for so little, it tends to earn high response rates and honest answers, which is part of its appeal.

The real value comes from where you ask it. CES is a transactional, journey-level measure: it tells you how much effort a particular interaction demanded, not how a customer feels about your brand in general. Attach it to specific journeys, resolving a billing query, returning an item, setting up the product, and the low-scoring ones point straight at customer friction worth removing.

It rarely lives alone. CES sits alongside CSAT, which measures satisfaction with an interaction, and NPS, which measures overall willingness to recommend. Each answers a different question, so teams commonly run them together: CES tells you how hard the experience was, and the others tell you how the customer felt about it and about you.

What's a good customer effort score?

There is no universal benchmark, and any single number is close to meaningless without knowing the scale behind it and the journeys being measured. A seven-point agreement score and a five-point effort score are not comparable, and even on the same scale, a returns process and an onboarding flow will naturally score differently.

The useful comparison is your own score over time, broken down by journey. A steady figure with one journey dragging is far more actionable than a single company-wide average. Read it as part of your wider voice of the customer programme, so effort is one input among several rather than a lone target.

Reducing effort is mostly about removing steps and waiting. The journeys that score worst tend to share the same culprits: long queues, having to repeat information, and answers that are hard to find. Strong customer self-service tackles all three by letting people resolve routine questions instantly, without a queue or a hand-off. When they get an accurate answer on the first try, and reach a resolution in the first interaction, the effort they spend, and their score, both move in the right direction.
