CES Calculator — Customer Effort Score

Customer Effort Score (CES) is one of the strongest predictors of customer loyalty.

The CES methodology is simple: after an interaction, ask customers to rate their agreement with the statement 'The company made it easy for me to handle my issue' on a 1-7 scale. The aggregate score reveals whether your support, onboarding, or purchasing processes create unnecessary effort. Companies that reduce customer effort see an average 12% increase in revenue.

Why measure customer effort?

Effort predicts churn

A customer who has to chase you to get something fixed leaves sooner than one who is simply unhappy with the outcome.

It is measured on a 1 to 7 scale

CES is the weighted average of every response. The higher it is, the less effort you asked of the customer.

AI removes friction, not just time

An immediate answer, on any channel, without repeating the context: three of the usual causes of a poor CES.

FAQ

Frequently asked questions

Customer Effort Score (CES) measures how much effort a customer had to exert to get an issue resolved, a request fulfilled, or a product used. It uses a 1-7 scale where 1 means 'very difficult' and 7 means 'very easy'. CES is one of the strongest predictors of future purchasing behavior and customer loyalty.

CES is calculated by dividing the sum of all individual scores by the total number of survey responses. For example, if 200 customers respond and the total score is 1,100, the CES is 1,100 / 200 = 5.5. The result falls on a 1-7 scale where higher scores indicate lower customer effort.

A CES score of 5.5 or above (on a 7-point scale) is generally considered good. Scores above 6.0 are excellent. The average CES varies by industry: SaaS companies average 5.4, e-commerce 5.1, banking 4.8, healthcare 4.5, and telecom 4.2. Any score below 4.0 indicates significant friction that needs immediate attention.

CES measures effort (how easy it was to interact with your company), while CSAT measures satisfaction (how happy the customer is with the outcome). CES is a better predictor of loyalty — 96% of high-effort customers become disloyal vs. only 9% of low-effort customers. CSAT captures a moment in time, while CES captures the quality of the experience process.

Key strategies to reduce effort: deploy AI chatbots for instant self-service (reduces wait times by 90%), implement omnichannel support so customers don't repeat themselves, proactively communicate status updates, simplify processes like returns and cancellations, and use a unified knowledge base. Companies that reduce effort see a 12% increase in revenue on average.
