Customer Effort Score (CES)

What is Customer Effort Score (CES)?

Customer Effort Score (CES) measures the effort customers expend to resolve support issues or achieve goals like purchases. Unlike traditional “satisfaction” metrics, CES quantifies the practical aspect: “Was it easy or troublesome?” Importantly, reducing customer effort improves long-term loyalty more effectively than satisfaction alone.

In a nutshell: Measuring “how much hassle did resolving this problem require?” Customers return more readily when hassle is minimal.

Key points:

• What it does: Scores the effort (hassle) customers experience interacting with companies
• Why it’s needed: Lower effort correlates with higher customer loyalty, predicting retention better than satisfaction
• Who uses it: Customer service, customer experience, contact center managers

How it works

CES measurement typically uses simple surveys. Upon issue resolution, companies ask customers to rate agreement with “the company helped me resolve my issue easily” on “1=Strongly disagree to 7=Strongly agree” scales, or “1=Very easy to 5=Very difficult” direct scales.

Aggregated scores reveal average CES, showing “how much effort we require of customers.” Investigation follows: “Why is effort high?” Identifying specific effort sources: “three phone transfers,” “three document requirements.”

Finally, organizations execute improvements: “Add web portal feature resolving in one visit,” “Send pre-required document list emails,” continuing CES measurement to verify improvement.

Calculation method

Basic CES score calculation:

• Average CES = Sum of all respondent scores ÷ Number of respondents
• Example: 100 respondents, 500 total score = CES 5.0

Benchmarks:

• 1-7 scale: 4.0+ is good (industry average ~4.5)
• 1-5 scale: 3.5+ is good (industry average ~3.7)
• Low effort experience satisfaction: ~91%
• High effort experience satisfaction: ~4%

Lower scores (higher effort) increase customer dissatisfaction and churn risk. Improve priority areas with particularly low scores first.

Why it matters

Low interaction effort increases trust in companies and repeat usage probability. Industry research shows 96% of low-effort experience customers maintain loyalty. Conversely, high-effort customers readily consider competitors. Companies also benefit—reduced effort decreases customer service burden, improving efficiency. Simplified complex procedures reduce inquiry volume, lowering overall support costs.

Real-world use cases

Insurance claim processing - Policymakers struggling with “five document submission requirements, two-week approval” high-effort processes. CES measurement enables improvement: “online submission with two documents, three business day approval.” CES improves from 3.2 to 5.8, churn declines.

Bank account opening - New customers struggle with “branch visit, document preparation, complex form completion.” CES reveals “very troublesome” ratings; web completion and photo ID verification improve scores from 2.1 to 5.3, new applications increase 30%.

Technology support - Bug reporting transitions from “email send, response wait, detailed information re-sending, resolution” multi-stage process to chat support. Real-time response reduces effort; CES improves 4.2 to 6.1.

Benefits and considerations

CES’s greatest advantage is exceptionally high customer loyalty prediction accuracy. CES better predicts “customer continued usage” than satisfaction surveys. Companies find clear improvement direction—“what to improve” is obvious. However, challenges exist: implementation requires investment; “web platform building” or “process redesign” demands time and money. Survey timing matters—asking one week after resolution (not immediately) reduces accuracy through memory fading. Additionally, excessive effort reduction risks eliminating quality-assurance processes.

Related terms

• Customer Satisfaction — Satisfaction and CES are distinct metrics; measuring both provides comprehensive understanding.
• Customer Loyalty — Low effort drives maximum loyalty improvement; high CES correlates with high loyalty.
• Customer Experience — CES quantitatively measures important customer experience aspects.
• Process Optimization — CES-indicated effort reduction requires process optimization.
• Net Promoter Score — Combined use provides more complete customer understanding.

Frequently asked questions

Q: How do you improve low CES scores?

A: Root cause identification is critical. Analyzing customer free-text comments identifies “what was troublesome.” Multiple unnecessary confirmation items, system complexity, and multi-department inquiries typically emerge. Fix high-priority causes first.

Q: How does CES differ from NPS (Net Promoter Score)?

A: NPS asks emotional questions (“Would you recommend to friends?”), while CES asks practical questions (“Was interaction easy?”). NPS indicates long-term loyalty; CES indicates immediate experience quality. Measuring both is most effective.

Q: How do you verify effort reduction isn’t costing too much?

A: Calculate improvement ROI. “100,000 yen effort reduction investment preventing 50,000 yen monthly churn recovers in 20 months.” Measure business impact alongside score improvements.
