Customer Effort Score
Customer Effort Score (CES) is a metric that measures how easy customers find it to interact with your company. It asks customers to rate the effort required to resolve an issue, complete a transaction, or get a question answered. The idea is simple: low-effort experiences drive loyalty and repeat business, while high-effort interactions push customers away. Companies track CES to identify and remove friction from the customer journey.
Formula: Ask "How easy was it to [solve your issue / complete your task]?" on a scale from 1 (very difficult) to 7 (very easy), or as agree/disagree with "The company made it easy for me to handle my issue."
How is Customer Effort Score calculated?
CES is measured with a single-question survey, sent immediately after a customer interaction. The two most common formats are:
| Format | Method | Calculation |
|---|---|---|
| 7-point scale | "On a scale of 1 to 7, how easy was it to [task]?" | Average score, or % scoring 5 to 7 (low effort) |
| Agree/disagree | "The company made it easy for me to handle my issue." (5-point: strongly disagree to strongly agree) | % who agree or strongly agree |
Some teams track CES as an average (mean score). Others report it as the percentage of customers who found the experience easy (scoring in the top 2 or 3 points of the scale). The second method is clearer for benchmarking.
Why does Customer Effort Score matter?
CES predicts customer loyalty more reliably than satisfaction alone. Research shows that customers who have low-effort experiences are more likely to renew, buy again, and speak positively about your company. When customers have to repeat themselves, wait on hold, or dig through a confusing help center, they remember the friction. Reducing that effort is one of the most direct levers you have to improve retention and word of mouth.
CES is part of good customer support metrics and helps you identify where the experience breaks down so you can fix it.

Frequently asked questions
What is a good Customer Effort Score?
Most companies aim for a CES above 5 on a 7-point scale, or above 70 percent agreement on the statement-based format. Higher scores mean customers find interactions easier. What matters most is the trend: steady improvement means you are removing friction from the experience.
How is Customer Effort Score different from CSAT or NPS?
CSAT measures satisfaction with a specific interaction. NPS measures loyalty and willingness to recommend. CES measures effort: how hard customers had to work to get what they needed. Low effort predicts retention better than high satisfaction alone.
When should you measure Customer Effort Score?
Measure CES immediately after a service interaction, like closing a support ticket, completing a return, or finishing onboarding. The question is most accurate when customers can still recall how easy or hard the interaction felt.
