Customer Effort Score (CES): What It Is, How to Measure It, and Why It Matters

Article Overview

Customer effort score measures how much work it took a customer to get something done, whether that’s booking, resolving an issue, or getting a refund, and you calculate it by averaging responses to a single ease-of-resolution question on a 1 to 7 scale (some teams use 1 to 5). The bands: 6.0 to 7.0 is low effort, 5.0 to 5.9 moderate, 3.0 to 4.9 high, and 1.0 to 2.9 very high. A score of 5.5 or above is good; top performers sit near 6.0 or higher. Low effort is worth chasing because McKinsey puts it at three new customers to replace one lost, with 80% of value creation at top growth companies coming from existing ones. Send it after a closed ticket or completed visit, then recheck in 30 to 60 days.

You might know whether your customers are satisfied. But do you know if they found interacting with your business easy?

That’s exactly what customer effort score (CES) measures.

CES tracks how easy or hard it was for a customer to get something done. That could be a booking, a support call, or a refund.

If it took too much effort, they’ll find someone easier to deal with next time.

For franchise and multi-location businesses, this is critical.

One location might be effortless to deal with. But another might be losing customers over something completely fixable. CES reveals both to you.

What it is, how to calculate it, how to run your first survey, what a good score looks like, and how CES compares to NPS and CSAT.

What Is Customer Effort Score (CES)?

Customer effort score, or CES, is a customer experience metric. It measures how much effort it took the customer to get something done. That could be resolving an issue, completing a purchase, or getting a question answered.

You ask customers one question right after an interaction. Their answer tells you where your experience is effortless and where it’s creating friction that costs you loyalty.

CES definition & the core question

To measure CES, you need to ask one question:

“How easy was it to resolve your issue today?”

Customers respond on a scale, typically 1 to 7. Low scores mean high effort. High scores mean low effort.

The question is asked right after a specific interaction:

A support ticket getting closed
A checkout completion
A service call wrapping up
A billing query getting resolved

The timing is what makes it useful. You’re capturing how the customer felt in that moment, while the experience is fresh.

It’s worth noting that CES doesn’t measure overall satisfaction. It measures one thing: how much work did this specific interaction cost your customer?

Why low effort drives loyalty

When an interaction is easy, customers come back. It’s that straightforward.

Think about it from your own experience. When a business makes something effortless, you don’t think twice about using them again. When it’s a hassle, you start wondering if there’s a better option out there.

Say there’s a customer who books a service appointment in two clicks. It takes 3 minutes. Easy. So, they come back next month.

Another customer spends 40 minutes on hold, gets transferred twice, and has to repeat their details three times. They are unlikely to book again.

And that second customer walking away? It costs your business a lot. According to McKinsey, it takes three new customers to replace the value of one lost customer.

On the flip side, McKinsey found that 80% of value creation at the world’s top growth companies comes from existing customers. The businesses that grow aren’t just chasing new leads. They’re making it easy for current customers to stay loyal and spend more.

Low effort is how you do that. Make interactions easy, and customers have every reason to come back, time and time again.

How to Calculate Customer Effort Score

Here’s how the customer effort score calculation works.

The CES formula

First, the formula:

CES = Sum of all scores / Total number of responses

You add up every score you received. Then, you divide by how many people responded. The result is your CES.

Let’s define each part:

Sum of all scores: Add every individual rating together. If 5 customers gave scores of 6, 7, 4, 5, and 6, you add those numbers up.
Total number of responses: How many customers answered the survey? In the example above, that’s 5.
CES: The number you get after dividing. This is your average effort score.

A higher number means customers found the experience easy. A lower number means they found it hard.

A worked example

Say you run a home services franchise. You sent a CES survey after 8 recent service calls.

Here are the scores you got back:

6, 7, 5, 7, 4, 6, 7, 6

Now, let’s run the calculation:

Step 1: Add all the scores together. 6 + 7 + 5 + 7 + 4 + 6 + 7 + 6 = 48.
Step 2: Count how many responses you received. 8 customers responded. So your total is 8.
Step 3: Divide the sum by the total responses. 48 / 8 = 6.0.

Your CES score is 6.0 out of 7. That’s a solid result.

It tells you most customers found the service experience easy to get through.

You might want to investigate what happened with that score of 4. That customer came up against a friction point somewhere.

A quick conversation with them could tell you exactly where.

CES scales (5-point vs. 7-point)

CES surveys use either a 5-point or 7-point scale. Both work.

Here’s the difference:

Feature	5-point scale	7-point scale
Range	1 to 5	1 to 7
Granularity	Broader ratings	More detailed ratings
Best for	Quick pulse checks	Deeper analysis
Benchmark availability	Less common	More widely used

The 7-point scale is the more widely used standard. It gives customers more room to express how they felt.

A customer who’d rate the experience a 5 on a 5-point scale might rate it a 6 on a 7-point scale. That nuance adds up as you track trends over months or years.

If you’re just getting started, go with the 7-point scale. It gives you better data to work with.

How to Run a CES Survey

A CES survey works best when it’s well-timed and worded right.

Send it at the wrong moment, and you’ll get low response rates. Word the question badly, and you’ll get unreliable data.

Here’s how to get both right.

When & where to ask

The golden rule: ask immediately after an interaction. You want the experience to be fresh in the customer’s mind.

Good moments to send a CES survey include:

Right after a support ticket is closed
Immediately after a service appointment wraps up
As soon as a purchase is completed
Right after a customer speaks to your team on the phone

Where should you ask the question? Here are your options:

Email: Works well for post-service follow-ups. Send it within an hour of the interaction.
SMS: High open rates. Great for field service businesses where customers just had someone at their home.
In-app or on-site: Ideal for digital interactions like checkouts or account management tasks.
Post-call IVR: For phone-based service teams. The customer rates the experience right after hanging up.

Question wording & best practices

The standard CES question is:

“How easy was it to resolve your issue today?”

Don’t veer too far from that phrasing. The simpler, the better.

Customers respond on a scale from 1 (very difficult) to 7 (very easy).

Here are a few tips to get reliable responses:

Ask about one interaction only. Don’t combine two touchpoints in one question.
Use plain language. Avoid corporate words like “experience” or “journey.” Say “issue” or “request” instead.
Add one optional follow-up. Try: “What could we have made easier?” That open field tells you the why behind the score.
Don’t ask too many questions. Opt for one rating question plus one optional text box.

CES vs. NPS vs. CSAT

What’s the difference between these metrics? Here’s a brief overview:

Metric	Core question	What it measures
Customer Effort Score (CES)	How easy was this?	Effort at a specific touchpoint
Net Promoter Score (NPS)	Would you recommend us?	Overall loyalty and sentiment
Customer Satisfaction Score (CSAT)	How satisfied were you?	Satisfaction with a specific interaction

What each measures

Now, let’s get into a bit more detail. Here’s what each metric measures:

What is a CSAT score? CSAT measures satisfaction. It captures how a customer felt about a specific interaction and whether it met their expectations.
What is Net Promoter Score? NPS measures loyalty. It asks whether a customer would recommend your business to someone else.
What is CES? It tells you how much work a customer had to do to get something done. It’s linked to one touchpoint and asked immediately after.

Not sure how CSAT and NPS differ from each other? Our guide to CSAT vs. NPS breaks that down.

When to use which

Think of these metrics like three different puzzle pieces:

Use CES right after a specific task. You want to know: was that easy?
Use CSAT when you want to know if a specific experience hit the mark. A new customer’s first appointment is a good use case.
Use NPS when you want the bird’s-eye view. Send it quarterly. It tells you how customers feel about your brand in general.

Using all three gives you the complete picture.

CES tells you where customers are losing patience. CSAT tells you if interactions are working well. NPS tells you if the overall relationship is healthy.

What’s a Good Customer Effort Score?

On a 7-point scale, a good customer effort score is 5.5 or above. A score of 6.0 or higher is what top-performing businesses tend to achieve.

Scores below 5.0 suggest that customers are working harder than they should be to get things done.

The lower the score, the higher the risk that customers will stop working with your business.

Benchmarks & interpretation

Here are the CES benchmarks and what different scores mean:

CES score	What it means	What to do
6.0–7.0	Low effort. Customers are getting through easily.	Maintain what’s working. Survey regularly.
5.0–5.9	Moderate effort. There’s some friction that’s worth investigating.	Find which touchpoints are scoring lower.
3.0–4.9	High effort. Customers are struggling.	Treat this as urgent. Check your process step-by-step.
1.0–2.9	Very high effort. Customers are likely to churn.	Act immediately. This is a retention risk.

A score above 5.5 is generally considered good. A score above 6.0 is where you want to be.

But here’s what the table won’t tell you: your score means more when you compare it to your own previous results than to a generic number.

A complex service business and a retail checkout will naturally score differently.

Tracking CES over time

One CES score is a snapshot. A series of scores is a story.

Tracking your score over weeks and months tells you whether the changes you made are working.

Did you update your booking process, as an example? Your next round of scores will tell you if it helped.

Here’s how to track it:

Survey after every significant interaction.
Record scores by location, team, or interaction type.
Review monthly so trends are visible sooner rather than later.

Importantly, be consistent. Ask the same question, at the same time, over and over again.

How to Reduce Customer Effort

No one wants to go through a high-effort experience with a business.

Make sure your customer journey is as effortless as possible by watching out for these friction points and implementing proactive fixes.

Common friction points

Most high-effort experiences come from the same handful of issues. Here are the ones that come up again and again:

Long wait times: Customers who wait too long to speak to someone rate the experience poorly. This might happen even if the outcome was good.
Repeating information: Having to explain the same issue to two or three different people is a sure-fire way to lose a customer’s patience.
Unclear next steps: When a customer doesn’t know what happens after an interaction closes, they call back. That’s effort they shouldn’t have to spend.
Hard-to-reach teams: If getting through to your business takes multiple attempts, your CES will reflect that.
Inconsistent processes: When two locations do the same thing differently, customers who’ve visited both take note. It creates confusion and erodes trust.

Fixing effort across locations

For multi-location businesses, inconsistency is the biggest culprit. Here’s how to address it:

Look at your CES data by location. Find the one with the lowest score. That’s where you start.
Map the interaction step-by-step. Talk to the team. Walk through what a customer experiences from first contact to resolution. Find exactly where the friction is.
Standardize the fix. When you’ve solved it at one location, document the new process using a standard operating procedure (SOP). Then, roll it out to every other location the same way.
Check CES scores again in 30–60 days. If the solution worked, scores at that location will improve. If they haven’t budged, there could be another friction point to find.

Tools to Measure & Track CES

Wondering which tools can help you send a CES survey and track results over time?

Survey & feedback tools

These tools can collect and analyze CES responses:

Listen360 acts as both customer feedback software and a feedback analytics platform. It’s purpose-built for multi-location businesses.
Typeform is an easy-to-use survey tool for branded, conversational experiences.
SurveyMonkey is another survey tool with good reporting.
Google Sheets is a free way to record your responses and share them with your team. You will need to manually enter the data, however.

Multi-location reporting

Multi-location reporting allows you to see CES scores for each location separately. You don’t just get one combined number for your whole business.

This is vital. If your overall score looks fine but one location is scoring poorly, you’d never know from a blended average. Location-level data shows you exactly where the problem is.

Doing this in spreadsheets can be a huge headache. You’re pulling data from multiple places, and by the time it’s together, it’s out of date.

Listen360 does this automatically.

All of your locations’ scores are collected and displayed in one place. You can see which locations are performing well and which have plenty of room for improvement.

Frequently Asked Questions

Here are quick answers to the questions people ask most about CES.

What is a good customer effort score?

On a 7-point scale, a score of 5.5 or above is considered good. Top-performers might score around 6.0 or higher.

How is CES calculated?

Add up all your survey scores. And then, divide by the total number of responses. That gives you your average CES.

For example, scores of 6, 7, 5, and 6 added together equal 24. Divided by 4 responses, and your CES is 6.0.

What’s the difference between CES and NPS?

CES measures how easy one specific interaction was. NPS measures how likely a customer is to recommend your business. CES is touchpoint-level. NPS is relationship-level.

Conclusion

Every business owner wishes they could read their customers’ minds. Measuring metrics like CES is the closest thing to it.

CES tells you how a customer felt about a specific interaction. Was it a total breeze? Or was it a complete nightmare?

Whatever the result, you can use that data to make educated changes to your operations.
