About this tool
Research published in the Harvard Business Review established that customer loyalty is driven far more by reducing user effort than by attempting to 'delight' customers with unexpected perks. Customer Effort Score (CES) measures how much friction a user experiences when interacting with your product or support team, asking: 'To what extent do you agree that the company made it easy for you to handle your issue?' scored on a standard 1-to-7 scale (1 = Strongly Disagree, 7 = Strongly Agree). High effort creates frustration and churn; low effort fosters habitual, loyal usage. Tracking CES across core workflows—such as API integration, team invites, and subscription changes—pinpoints exact UX bottlenecks. Use this tool to compute your average CES.
How It Works
- 1Input individual user rating scores (from 1 to 7) or comma-separated survey responses.
- 2Inspect the calculated average Customer Effort Score across all responses.
- 3Review your effort rating classification (Low Effort / High Retention vs High Friction / Churn Risk).
Formula & Math
Transparent LogicCES = Sum of All Effort Ratings / Total Number of Responses
Worked Practical Example
A SaaS surveys 5 users after onboarding: scores are 6, 7, 6, 5, 6.
Calculation / Steps
Sum = (6 + 7 + 6 + 5 + 6) = 30. Total = 5. Average = 30 / 5 = 6.00.
Expected Result
Average CES of 6.00 / 7.0 ('Low Effort / High Retention' status).
Frequently Asked Questions
What is considered a good Customer Effort Score on a 7-point scale?+
An average score of 5.5 or higher indicates a low-friction, high-retention customer experience. A score below 4.5 indicates severe operational friction.
Where should CES surveys be deployed?+
Immediately following complex user milestones: finishing initial product onboarding, completing a billing upgrade, or resolving a technical support issue.
Why does high effort cause subscription churn?+
When users feel a tool requires excessive manual effort to configure and maintain, they seek out simpler, more automated alternatives.
