Customer Effort Score (CES): Definition, Actionable Tips, and Measurement Guide

Think about the last time you tried to fix a billing error or solve a technical glitch. Did you have to explain your problem to three different people? Did you have to wait on hold for twenty minutes only to be disconnected?

In those moments, you didn’t want a “delightful” experience. You didn’t want a discount code. You just wanted the issue resolved without having to fight for it. This is the core of the Customer Effort Score (CES).

For decades, customer experience management was obsessed with “wowing” the customer. But in 2010, a landmark study changed everything. The research proved that customer loyalty isn’t built on grand gestures; it’s built on how little work the customer has to do.

The Shift of Customer Effort Score

To truly get the definition of customer effort score and understand customer journey management, you need to read the original research from Gartner (formerly CEB) published in the Harvard Business Review. This was not just a minor survey; it was a complete paradigm shift in the way we consider loyalty.

The researchers, led by Matthew Dixon, Karen Freeman, and Nicholas Toman, analyzed over 75,000 customer interactions. They were looking for the “secret sauce” of loyalty. What they found was a shock to the system: delighting customers does not build loyalty. Most companies spend a fortune on “extra” service, but the data shows it has almost zero ROI.

The 96% vs. 9% Reality

The study revealed two devastating statistics that still define cx metrics today:

1. 96% of customers who had a “high-effort” experience became disloyal. This means they would spread negative word of mouth or switch to a competitor.
2. Only 9% of customers who had a “low-effort” experience showed any disloyalty. The easiest way to keep a customer is the best.

In short, a customer service representative singing a song doesn’t make up for a 30-minute wait time. Don’t make it difficult for anybody to deal with your business, or they will go elsewhere. It’s that simple.

What Is Customer Effort Score (CES)?

Customer Effort Score (CES) is a customer experience metric based on the effort required for a particular interaction. The customer effort score (CES) is transactional, unlike the Net Promoter Score (NPS), which is based on overall satisfaction and the relationship.

It asks one fundamental question: “How easy was it to get your problem solved today?” It is widely used in call centers, support centers, and for digital experience tracking.

The Evolution: CES 1.0 vs. CES 2.0

The way we ask the question has changed over time to improve survey results.

• CES 1.0: The original customer effort score question was: “How much effort did you personally have to put forth to handle your request? on a scale of 1 to 5.
• CES 2.0: Gartner found the old version was confusing. If a customer says 1, does that mean 1 effort (good) or a low score (bad)?

To rectify this, they developed Customer Effort Score (CES) 2.0, the standard used in the industry today. It asks you to agree or disagree with the following statement: “The company made it easy for me to deal with my issue.” It has a Likert scale attached (1-7 typically).

CES vs. NPS vs. CSAT: The Battle of CX Metrics

A common mistake in experience management is trying to pick just one metric. To truly understand your customer journey, you need a combination of NPS and CSAT alongside CES data.

5 Reasons Why CES Often Wins as a Predictor

1. It is a leading indicator: While NPS tells you how they feel now, Customer Effort Score (CES) tells you if they will come back after their next interaction.
2. It identifies friction points: Because it is transactional, it tells you exactly which channel or step in the process is broken.
3. It correlates with repurchase rates: High ease is more closely tied to repeat product purchase than high “happiness.”
4. It reduces service costs: By identifying where customers struggle, you can implement self-service options and reduce call center volume.
5. It is highly actionable: If a customer gives a low score on a support interaction, you know exactly which customer service team needs better training.

How to Measure and Calculate Your Customer Effort Score

The customer effort score formula is relatively simple, but the customer effort score analysis is where the value lies. You need to look at the results across different touchpoints.

1. The Average CES Formula

To find your average score, use this formula:

(Total Sum of Scores) ÷ (Total Number of Responses) = Your CES Score

For example, if you collect 150 responses and the sum of all scores is 900, your score is 6.0. This would be considered an excellent benchmark.

2. The Net Effort Score (NES)

Some businesses prefer a more aggressive calculation similar to Net Promoter Score.

• Step 1: Calculate the % of “Agree” (scores 6 and 7).
• Step 2: Calculate the % of “Disagree” (scores 1, 2, and 3).
• Step 3: Subtract Disagree from Agree.

3. Distribution Analysis

Don’t just look at the average; look at the score distribution. If half your customers give a 7 and the other half give a 1, your average is a 4, but your business is in trouble. You need to find out why that 50% is having a “high-effort” nightmare.

4. Cross-Channel Comparison

Measure Customer Effort Score (CES) across email, chat, phone, and social media support. You might find that your chat is a 6.5, but your phone support is a 3.0, indicating a major process issue in your call center.

5. Follow-up “Why” Questions

Be sure to have an open-ended text box at the end of the survey. The number indicates their emotion, the comment indicates their reasoning, giving you the opportunity to complete the cycle.

What Is a Good Customer Effort Score Benchmark?

Benchmarks are tricky because they change based on your industry. However, looking at Gartner and Qualtrics data, we can set some general goals for a 1-7 scale.

5 Levels of CES Performance

1. Below 4.0 (The Danger Zone): This is a massive warning sign. Your customers are facing significant obstacles, and your attrition rates are likely climbing.
2. 4.0 to 5.0 (The Neutral Zone): You are meeting basic customer expectations, but you aren’t creating a competitive advantage.
3. 5.0 to 6.0 (The Good Zone): You have a solid customer experience strategy. Most interactions are smooth, but there is still some friction.
4. Above 6.0 (The Gold Standard): You have created a low-effort experience that drives customer retention. This is where loyalty is built.
5. Steady Improvement: More important than the static benchmark is the trend. Is your score higher this month than it was after your last product update?

5 Actionable Tips: How to Reduce Customer Effort

Knowing your Customer Effort Score (CES) score is useless if you don’t use the data to change your business strategy. Here is how modern companies are improving your customer effort.

1. Embrace Real Self-Service Options

Modern users hate picking up the phone. A vast majority of people prefer to fix the issue on their own rather than communicating with a member of customer service.

• The Fix: Create a comprehensive knowledge base, self-help, and troubleshooting flows. Ensure your search functions actually lead to answers.
• The Result: You reduce wait times for those who actually need to speak to an agent, lowering the amount of effort for everyone.

2. Solve the Channel Switching Problem

So if a customer sends a message and you respond with “Please call our customer service”, you’ve just double-worked the customer. It’s a major pain point on the customer journey.

• The Fix: Use an omnichannel contact center like Dialaxy. This ensures the conversation history follows the customer.
• The Result: If they move from social media support to a phone call, the call center agent already has the context and history.

3. Eliminate Repetition with CRM Integration

Nothing drives a high amount of effort like a customer having to repeat their account number or issue four times. It makes the company look disorganized and frustrates the customer.

• The Fix: Use CRM integration so that when a call comes in, your system automatically pulls up purchase history and previous support tickets.
• The Result: Your staff can start the conversation with, “I see you’re calling about your recent order status,” instead of “Who are you?”

4. Practice Next Issue Avoidance.

Don’t just fix the current issue. Predict the next one to prevent a second request.

• The Fix: When a customer calls to ask for the setup of a new product, don’t simply complete the setup. Offer to sync it with their mobile devices if they would like it to be.
• The Result: This prevents a second interaction and lowers the overall effort of the relationship over time.

5. Empathetic Engineering of Processes

Sometimes the friction isn’t the representative; it’s the process. If a manager’s approval is required for a $5 credit, you are making things hard for no reason.

• The Fix: Empower your customer service representatives to make small decisions without escalation paths.
• The Result: The interaction is resolved in one step, drastically increasing your CES score and reducing the risk of call center burnout. 

The Future: Agentic AI and Generative AI in CES

We are entering the era of Agentic AI. Unlike old chatbots that just gave pre-written answers, modern AI agents can actually take action on behalf of the user.

5 Ways AI is Lowering Customer Effort

1. Predict Intent: Generative AI can read customer behavior and anticipate what he or she wants to say before they even begin speaking.
2. Personalized Routing: route a customer to the specific Customer Experience Expert for the unique customer issue using NLP.
3. Automate Resolution: Handle order status, onboarding sessions, and product purchase questions without ever needing a human representative.
4. 24/7 Availability: AI doesn’t have wait times. A customer doesn’t have to do anything to obtain a solution at 3 am.
5. Sentiment Analysis: AI systems can automatically detect high-effort interactions and alert the manager to intervene and complete the interaction before the customer walks away.

Not only are you saving money, but you’re also minimizing customer effort with the help of customer service automation.

5 Common Mistakes to Avoid with CES Surveys

1. Surveying for the wrong things: Don’t use CES for general brand sentiment. It is designed for specific interactions, like a support ticket or a checkout page.
2. Poor Timing: If you send the CES survey three days after the call, the customer has forgotten the friction. You must send it immediately to get accurate data.
3. Ignoring the “Text Box”: The score tells you that they struggled. The follow-up questions and open text boxes let you know why, and only with that information can you improve.
4. Inconsistency in Scales: Don’t change scales, e.g., from 1-5 to 1-7. Choose one, and use it consistently to maintain consistent and accurate CES data over time.
5. Focusing only on the Average: A “4.0” average can hide a lot of unhappy customers. Look at the patterns and the “bottom box” scores to find where your brand is failing.

Conclusion

In the realm of customer experience (CX), ease is the new loyalty. You can have the best product in the world, but if your customer support is a high-effort nightmare, your customer churn will eventually catch up to you.

By using the Customer Effort Score (CES), you stop guessing and start measuring the friction points that are hurting your bottom line. It is a power metric that connects directly to customer retention, repurchase rates, and word of mouth.

Stop trying to delight. Start trying to make it easy. Tools like Dialaxy help streamline communication channels, give agents the context they need, and make things easy with AI. They will be reflected in your retention rates, your customer satisfaction, and your company growth.
