What Is CES? Customer Effort Score Explained

Most CX programmes are built around a flawed assumption: that delighting customers is what keeps them. However, the research says otherwise. What actually drives loyalty is not exceeding expectations. Instead, it is removing the barriers that make normal interactions unnecessarily hard.

That is what Customer Effort Score measures. Not happiness. Not loyalty. Effort.

Where CES Came From, and Why It Matters

Matthew Dixon and his colleagues at CEB (now Gartner) published "Stop Trying to Delight Your Customers" in Harvard Business Review in 2010. The findings were uncomfortable for every company investing in "wow moments":

• 96% of customers with a high-effort service experience became more disloyal
• 88% of high-effort customers spread negative word of mouth
• Reducing effort was a stronger driver of loyalty than trying to exceed expectations

The implication is stark. Therefore, your priority should not be making things wonderful. It should be making things easy. Delight is a bonus. Ease is the foundation.

The CES Question

The standard CES question is a statement, not a question:

"The company made it easy for me to handle my issue."

Customers respond on a 7-point scale:

• 1 = Strongly disagree (high effort, bad)
• 7 = Strongly agree (low effort, good)

Common variants include "How easy was it to resolve your issue today?" with a difficulty scale. Either works, but pick one and stick with it. After all, changing the wording breaks your trend data.

Scale: 1-7 Low effort (good): Score 5-7 High effort (risk): Score 1-3 Measures: Friction and customer effort Best for: Support, checkout, onboarding, complaints Typical frequency: Immediately after interaction

Calculating CES

Straightforward:

CES = Average score of all responses

Five customers score 6, 7, 5, 4, and 6:

CES = (6 + 7 + 5 + 4 + 6) / 5 = 5.6

You can also segment responses into low effort (5-7), neutral (4), and high effort (1-3) to see the distribution. In fact, the distribution often tells you more than the average. A mean of 5.4 with 20% scoring 1-3 is a different situation than a mean of 5.4 with 5% in the danger zone.

Where CES Belongs (and Where It Does Not)

CES is a transactional metric. It measures friction at specific touchpoints. It is not a substitute for NPS as a relationship metric and it does not measure emotional satisfaction the way CSAT does.

Where CES works best

Customer support. This is CES territory. After every support interaction, whether chat, email, phone, or self-service, measure how hard it was to get help.

Checkout and payment flows. Cart abandonment is overwhelmingly caused by friction, not indecision. CES pinpoints whether your checkout is the problem.

Onboarding. Customers who struggle in the first weeks are at severe risk of quietly churning at renewal. CES tells you if onboarding is too complex before the customer tells you by leaving.

Returns and complaints. These are already negative experiences. Making them hard as well is a guaranteed path to losing the customer. CES here can preserve relationships that would otherwise end.

Self-service portals. If your knowledge base is supposed to reduce support load, CES tells you whether it actually does.

Where CES does not work

Do not use CES to measure overall brand perception, emotional connection, or long-term loyalty. Those are NPS and CSAT territory. CES is surgical, not strategic.

CES vs. CSAT vs. NPS

Question	Best Metric
Will this customer recommend us?	NPS
Was this specific experience satisfactory?	CSAT
Was this process easy?	CES
Is this customer likely to churn?	CES
Which touchpoints need work?	CSAT + CES

CES Benchmarks by Industry

CES benchmarks are less established than NPS benchmarks because the metric is younger and calculation methods vary. These figures are indicative on a 7-point scale:

Industry	Typical CES Average
SaaS / Tech Support	5.0-5.8
E-commerce / Returns	4.8-5.5
Financial Services	5.2-5.7
Telecommunications	4.5-5.2
Healthcare	5.0-5.5

Above 5.5 is solid. Below 4.5 is a clear signal that friction is actively driving customers away.

What We See in Practice

Among the B2B companies we work with, a few patterns recur:

CES reveals problems that CSAT hides. A customer can report being "satisfied" with a support interaction that took three transfers and two days. The outcome was fine, but the effort was high. CSAT scores 4 out of 5. CES scores 2 out of 7. The CSAT score suggests everything is working. The CES score shows the process is broken.

Moreover, onboarding CES is the strongest early-churn predictor. Companies that measure CES at day 7 and day 30 of onboarding can intervene before the customer mentally disengages. By the time you send a quarterly NPS survey, a struggling customer has already decided to leave.

Self-service CES is consistently underused. Most companies build a knowledge base and assume it works. Measuring CES on self-service usage reveals whether customers actually find what they need, or whether they give up and call support anyway.

Common Mistakes with CES

Treating CES as a relationship metric. CES is transactional. Sending a CES survey once a quarter to your whole customer base makes no sense. Trigger it after specific interactions.

Only looking at the average. A CES of 5.2 sounds acceptable. Yet if 25% of respondents scored 1-3, you have a serious friction problem with a specific subset of customers. Always look at the distribution.

Not asking the follow-up question. A CES score tells you effort was high. It does not tell you why. Always include one open-ended question: "What could we have done to make this easier?"

Measuring without ownership. If nobody owns the CES score for a specific process, nobody improves it. Assign process owners before you start measuring.

Five Ways to Reduce Customer Effort

1. Invest in self-service. Most customers prefer to solve problems themselves. A well-structured knowledge base, clear documentation, and an effective search function reduce effort for the customer and load for your support team.
2. Remove unnecessary steps. Walk through your most important customer-facing processes and ask: can we remove a step here? Can we pre-fill this form? Can we eliminate this approval? Every extra step is effort, and effort drives churn.
3. Reduce support handoffs. Being transferred from agent to agent is one of the highest-effort experiences a customer can have. Track first-contact resolution as a KPI and give agents the authority and tools to resolve issues without escalation.
4. Communicate proactively. Shipping updates, status notifications, known-issue alerts. Every proactive message is a support ticket that never gets created. That is effort removed before the customer even notices.
5. Optimise for mobile. A large and growing proportion of customer interactions happen on phones. If your flows are clunky on mobile, you are generating effort for the majority of your users. Test every critical process on mobile devices.

CES and Churn

This is the core argument for CES. Gartner's research found that:

• Customers with low-effort experiences had a 94% likelihood of repurchasing
• Low-effort customers were 88% likely to increase their spending
• High-effort customers were 4 times more likely to become disloyal than merely dissatisfied customers

Satisfaction does not retain customers. Ease does. Consequently, if you are serious about reducing churn, CES should be part of your measurement stack. Pair it with NPS for the strategic view and CSAT for touchpoint detail, and you have a complete picture.
