Customer Effort Score Calculator

Q: What is a good customer effort score?

A good customer effort score depends on the scale you use : On a 1-5 scale, a score below 3.5 is considered moderate , and below 2 is excellent . On a 1-7 scale, a score below 5 is moderate and below 3 is excellent . The lower the score, the less effort your customers have to put in, which is always the goal.

Q: What is the customer effort score scale?

The customer effort score scale is the rating range customers use to answer the CES question . The two most common options are: A 1 to 5 scale , where 1 is very easy, and 5 is very difficult. A 1 to 7 scale , where 1 is very easy, and 7 is very difficult. Both produce an average score that you interpret the same way: the lower the score, the less effort your customers had to put in.

Q: How is customer effort score different from NPS?

Customer effort score vs. NPS : CES measures how easy a specific interaction was, while NPS (net promoter score) measures overall loyalty by asking how likely a customer is to recommend your company. CES is transactional and best used right after a support interaction, a purchase, or an onboarding step. NPS is relational and works better as a periodic pulse check. Use CES to find friction in specific touchpoints and NPS to track overall sentiment over time.

Q: How do I improve your customer effort score?

To improve your customer effort score : Identify where friction is highest. Expand self-service options so customers can resolve issues independently. Reduce response and resolution times. Simplify checkout, onboarding, or account management flows. Train support teams to resolve issues in a single interaction. Run a new customer effort score survey after each change.

Q: Is 2.5 a good customer effort score?

Yes, a customer effort score of 2.5 is excellent on a 1-7 scale and moderate on a 1-5 scale , assuming 1 is very easy and 7 is very difficult. The choice between 1-7 and 1-5 scales depends on how much granularity you want in the responses. The 1-7 scale captures more subtle differences in customer effort, but the 1-5 scale is faster and easier to interpret.

Welcome to Omni Calculator’s customer effort score calculator, which helps you measure how easy it is for customers to interact with your business.

The customer effort score (CES) is built around a simple customer effort score question: how much effort did the customer have to put in to get their issue resolved.

Based on the responses, the customer effort score formula tells you whether your business is delivering a low-effort experience or creating unnecessary friction. Use this calculator to find out what a good customer effort score is for your business.

What is customer effort score?

The customer effort score (CES) is a customer experience metric that measures how easy it is for customers to interact with your business. It captures the effort a customer must put in to complete a specific action, whether that’s resolving a support issue, making a purchase, setting up a product, or navigating your website.

CES is collected through a short survey sent right after an interaction. The results tell you where your business is creating friction and where the experience is already smooth.

Companies use CES alongside other metrics such as NPS (net promoter score) and CSAT (customer satisfaction) to get a fuller picture of the customer experience.

The main advantage of CES over other metrics is its predictive power at the touchpoint level. A high-effort interaction is strongly linked to customer churn, while a low-effort one is linked to repeat purchases and loyalty.

💡 If you want to track overall loyalty instead of interaction-level friction, check out our NPS calculator.

The customer effort score formula

The customer effort score formula is a weighted average of all responses collected in a customer effort score survey. To calculate your customer effort score, follow these steps:

Multiply each score value by the number of customers who gave that response.
Add all those results together.
Divide by the total number of responses.

For example, if 10 customers gave a score of 2, 5 gave a score of 3, and 5 gave a score of 5 on a 1-5 scale:

\begin{aligned} \text{CES} &= \cfrac{(10 \times 2) + (5 \times 3) + (5 \times 5)}{10 + 5 + 5} \\[1em] &= \cfrac{20 + 15 + 25}{20} \\ &= 3.0 \end{aligned}

The result is a single number that represents the average effort level across all respondents. The lower the number, the less effort your customers have to put in.

If you are wondering what a good customer effort score is, anything below 3 on a 1-5 scale or below 4 on a 1-7 scale generally indicates a smooth experience.

🙋 Before running a customer effort score survey, use our sample size calculator to make sure you collect enough responses for a reliable result.

How to use this customer effort score calculator

Using this customer effort scale calculator is as simple as it gets:

Select a scale. The calculator supports two scales:
- A 1-5 scale, where 1 is very easy, and 5 is very difficult.
- A 1-7 scale, where 1 is very easy, and 7 is very difficult.
Enter the number of responses for each score.
That’s it! The customer effort score calculator will display your CES.

Note, you don’t need to know how to calculate the customer effort score at all. Simply, use this calculator after running a CES survey to quickly process your results without doing the math by hand.

🙋 If you are comparing results across different time periods or teams, make sure you use the same scale each time so the numbers are comparable.

Have you wondered how many answers you need to trust your customer effort score? Our confidence interval calculator can help you with this issue by showing the lower and upper bounds of your mean result.
