Customer Effort Score (CES): What It Is and How to Measure It
What Is Customer Effort Score?
Customer Effort Score (CES) measures how much effort a customer had to expend to accomplish a specific task with your company, such as resolving a support issue, completing a purchase, or finding information. The core idea is simple: the easier you make things for customers, the more loyal they become.
CES was introduced by the Corporate Executive Board (now Gartner) in a landmark 2010 Harvard Business Review article. Their research found that reducing customer effort is a stronger predictor of loyalty than delighting customers. In other words, removing friction matters more than adding wow moments.
The standard CES question asks respondents to rate their agreement with a statement like 'The company made it easy for me to handle my issue' on a scale from strongly disagree to strongly agree. This framing focuses on the experience rather than the company as a whole.
CES vs CSAT vs NPS
CES, CSAT, and NPS each measure different aspects of the customer experience. Customer Satisfaction (CSAT) asks how satisfied a customer is with a specific interaction. NPS measures overall loyalty and likelihood to recommend. CES specifically targets the ease of the experience.
CES is best suited for transactional touchpoints where effort is a key factor: support interactions, onboarding flows, checkout processes, and self-service tasks. NPS is better for gauging overall brand sentiment, while CSAT works well for general post-interaction feedback.
The three metrics complement each other rather than competing. Many organizations use NPS for quarterly relationship health checks, CSAT for broad post-interaction feedback, and CES specifically for processes where reducing friction is a strategic priority.
Designing Effective CES Questions
The most common CES format uses a seven-point Likert scale ranging from strongly disagree to strongly agree. The statement should reference the specific interaction: 'The company made it easy for me to resolve my issue' is better than a vague 'It was easy to work with us.'
Always send CES surveys immediately after the interaction while the experience is fresh. A delay of even 24 hours reduces accuracy because respondents start to forget details and their emotional response fades. Trigger-based delivery, such as automatically sending the survey after a support ticket closes, is ideal.
Follow the CES question with an open-ended question asking what would have made the experience easier. This qualitative data is where you find the specific friction points to fix. Without it, you know effort is high but not why.
Calculating Your CES Score
There are two common methods for calculating CES. The first is a simple average: sum all responses and divide by the number of respondents. On a seven-point scale, a score above five generally indicates a low-effort experience, while below four suggests significant friction.
The second method mirrors NPS by categorizing respondents. Those who selected six or seven are low-effort (positive), four or five are neutral, and one through three are high-effort (negative). Subtract the high-effort percentage from the low-effort percentage for a single score.
Whichever method you choose, be consistent over time so you can track trends. The absolute number matters less than the direction. If your CES improves from 4.2 to 4.8 over two quarters, you know your effort-reduction initiatives are working.
CES Benchmarks and Targets
CES benchmarks vary by industry and interaction type. Support interactions tend to have lower CES scores than purchase experiences because customers contact support when something has already gone wrong. Comparing your CES to your own historical performance is more useful than cross-industry comparisons.
As a general guideline on a seven-point scale, scores above 5.5 indicate a genuinely low-effort experience, scores between 4.0 and 5.5 suggest room for improvement, and scores below 4.0 signal serious friction that is likely driving customers away.
Track CES by channel, interaction type, and customer segment. Your phone support CES might be excellent while your self-service portal CES is poor. Segment-level data tells you exactly where to invest in improvements.
Strategies for Reducing Customer Effort
Map your customer journey and identify every point where customers must exert effort: filling out forms, waiting on hold, navigating menus, repeating information, or switching between channels. Each of these is an opportunity to simplify. Prioritize the friction points that affect the most customers.
Invest in self-service options that actually work. A well-designed knowledge base or FAQ can resolve common questions without any human interaction. However, poorly designed self-service that sends customers in circles is worse than no self-service at all. Test your self-service flows regularly.
Empower frontline staff to resolve issues in a single interaction. Transfers between departments, callback requirements, and escalation processes all multiply customer effort. When an agent can solve the problem right away, CES scores improve dramatically.
Implementing CES in Your Organization
Start with one or two high-impact touchpoints rather than rolling CES out everywhere at once. Support interactions and onboarding processes are common starting points because they are effort-intensive and directly tied to retention outcomes.
Integrate CES data into your operational dashboards alongside other metrics. When managers see real-time effort scores for their team or channel, they can identify and address issues quickly. Set up alerts for unusually low scores so problems do not fester.
Create a closed-loop process for high-effort responses. When a customer reports a difficult experience, trigger a follow-up to understand and resolve the issue. This recovery action can turn a frustrated customer into a loyal one and provides detailed feedback about where your processes break down.
Building a Low-Effort Culture
Reducing customer effort is not a one-time project but an ongoing discipline. Build effort awareness into your product development, process design, and customer service training. Before launching any new process or feature, ask the question: does this make things easier or harder for the customer?
Share CES results and customer verbatims with everyone in the organization, not just customer-facing teams. Engineers, designers, and operations staff all influence the customer experience. When they hear directly from customers about friction, they are motivated to fix it.
Celebrate effort-reduction wins publicly. When a team simplifies a process and CES scores improve, recognize that achievement. Over time, this reinforces a culture where ease of use is valued as highly as new features or cost savings.
