Customer effort score (CES).

The loyalty signal that asks a smarter question than how much do you like us. Here is what customer effort score is and why low effort predicts retention.

Definition
Customer effort score (CES) measures how hard a customer had to work to get value or resolve an issue, usually on an ease scale after a key interaction.

The insight behind CES is simple, effort drives disloyalty more than delight drives loyalty. Customers rarely leave because you failed to wow them. They leave because you made things hard. CES targets the friction that actually causes churn.

How to calculate it

Use CES at friction points, NPS for overall sentiment, see net promoter score.

Benchmarks

Why customer effort score beats NPS at friction points.

NPS asks how customers feel overall. CES asks how hard a specific moment was, which is more actionable. Research consistently finds that reducing effort predicts retention better than increasing delight, because friction is what pushes people out the door.

CES and NPS answer different questions, so use both. CES diagnoses the painful step, the clunky onboarding or the slow support resolution. NPS reads the relationship overall. Measuring effort at the moments that matter surfaces the churn drivers a satisfaction score hides.

How to improve it

How to use customer effort score well.

01

Measure at friction points

Fire CES after onboarding, support or a key task, where effort actually happens.

02

Act on the worst moments

A high-effort step is a churn driver wearing a survey result. Fix it first.

03

Pair it with NPS

CES diagnoses the painful moment. NPS reads the overall relationship. Use both.

04

Reduce effort, do not chase delight

Cutting friction protects retention more reliably than trying to wow people.

Common questions

Questions about customer effort score.

What is customer effort score?+

A metric measuring how much effort a customer had to expend to get value or resolve an issue, usually on an ease scale.

How is customer effort score calculated?+

Ask customers to rate how easy a specific interaction was, often on a 1 to 7 scale, then average the responses.

Why does customer effort score matter?+

Because effort drives disloyalty more than delight drives loyalty. Customers churn when things are hard and CES targets that friction.

Should I use CES or NPS?+

Both. CES diagnoses the effort of a specific moment, while NPS reads the overall relationship. They answer different questions.
