Customer Effort Score (CES) Calculator | Quantify How Easy Support Was

Enter how many respondents chose each effort level and instantly calculate your Customer Effort Score (CES) for free. Supports both 5-point and 7-point scales, showing the low-effort response rate and average score at a glance.

What the customer effort score measures

The customer effort score measures **how much trouble it took a customer to achieve their goal.** You ask something like "how much effort did you have to put in to get your issue resolved" on a rating scale and tabulate the answers. Where satisfaction and recommendation scores ask how good the experience was, **the effort score approaches customer experience from the other side, asking how tiresome it was.**

The metric spread on the back of an argument that **reducing effort does more to prevent customers leaving than delighting them does.** Removing the need to be passed between departments and to explain the same thing twice, so the argument runs, drives retention further than aiming to exceed expectations. Enter the number of responses at each effort level and this tool works on either a five-point or seven-point scale to give you **the share of low-effort responses and the mean score.**

How to calculate the score

Choose the scale Select whether you asked on a five-point or a seven-point scale.
Enter the count at each effort level **Values near one mean it was easy; higher values mean more trouble was involved.**
Check the low-effort share You see the proportion who answered that it was easy.
Read the mean score The overall average is shown alongside.
Record it per touchpoint Keeping the figures separate by occasion — an enquiry, a return, a cancellation — makes them useful for comparison.

Tips for getting more out of it

CES tells you exactly where to fix your process next — a spike in high-effort responses points straight at a confusing step or an unclear FAQ.
Use a 5-point scale for routine support tracking, and a 7-point scale when you need to detect smaller shifts over time. Pick the one that fits your goal.
Measuring with the same question and scale over time lets you compare the effect of UI changes or process simplification numerically.
Check both the low-effort response rate and the average effort score together — the average helps you see the overall trend without being skewed by a handful of extreme responses.
If CES comes back low (high effort), read the free-text comments to pinpoint exactly which step in the process was causing the friction.

Where this helps

Improving the path through support

**Identify what the effort actually consists of and you can fix it.** Track whether it is being passed around, repeating yourself, or waiting.

Catching early signs of churn

Customers whose effort score is worsening are held to be more likely to leave, which gives you grounds to act early.

Reading it with CSAT and NPS

**Satisfied yet put to considerable trouble** is a real combination. Either metric alone will miss it.

Measuring the effect of a help centre

Comparing before and after improving the self-service path shows whether effort actually fell.

Customer experience terms explained

Customer effort score: A measure of the trouble a customer had to go to. **Lower is better**, which inverts the direction of the other metrics.
Low effort: Answers at the "it was easy" end. **Taking this share as the headline figure is the usual practice.**
CSAT: A measure of satisfaction with a specific experience, given by the share choosing the top two levels.
NPS: Asking whether someone would recommend you, then subtracting the share of detractors from the share of promoters.
Being passed around: The state in which a customer repeats the same explanation each time the department changes. **It is a classic driver of a poor effort score.**
Self-service resolution rate: The share of customers who solved their problem without making contact. It tends to move together with improvements in effort.

Frequently Asked Questions

It varies by industry, but a low-effort response rate (bottom two levels) of 75% or higher is generally considered excellent, 60-75% good, 40-60% average, and below 40% suggests room for improvement. Because industry averages vary widely, comparing against your own historical scores is usually more practical.

CES measures how much effort a process required, CSAT measures satisfaction with the outcome, and NPS measures longer-term loyalty and willingness to recommend. Since each metric targets something different, they are typically used together or chosen based on what you want to learn.

Using only the single lowest (or highest) level as the cutoff can make the score unstable because the sample size shrinks. Grouping the bottom two levels together (a "Low 2 Box" approach) is the widely used industry convention for a more stable "low effort" measure.

There is no single right answer. A 5-point scale works well for straightforward tracking, while a 7-point scale is better when you need to detect finer-grained changes or want to match the granularity of an existing survey.

Start by reading the free-text comments from respondents who reported high effort, and look for specific causes such as overly complex procedures, unclear instructions, or being passed between departments — that's the first step toward improvement.

Side Note — Why "Reduce Effort" Beats "Delight the Customer"

The Customer Effort Score (CES) was introduced in the 2010 paper "Stop Trying to Delight Your Customers," published by CEB (now part of Gartner). The paper argued that the biggest driver of customer loyalty isn't delighting customers — it's reducing the effort they have to put in, challenging the multi-dimensional satisfaction surveys that had dominated the field up to that point.

There are two common question formats. One is an agreement-scale version ("How much do you agree the company made it easy to handle your issue?"), where a higher number means easier. The other, used here, is a direct effort-scale version ("How much effort did you have to put forth?"), often called CES 2.0, where a lower number means easier.

CES matters most at touchpoints where customers are actively trying to resolve a problem, such as support desks and call centers. While CSAT measures satisfaction with the outcome and NPS measures long-term loyalty, CES captures how smooth the experience itself was — which strongly predicts whether a customer will bother contacting the company again. CEB's research found that companies with lower customer effort tend to see higher repeat business.
