Definition
Customer effort score (CES) is a single-question survey metric that measures how much effort a customer needed to complete a specific task. It answers one question: "How easy was that?"
Why it matters
Effort predicts churn better than satisfaction. A customer can be satisfied with your product overall but still leave because one critical task was too hard. That's why CES matters more than NPS during onboarding.
When customers hit friction early, they don't file complaints. They just leave. CES catches those friction points before they become churn events.
High-effort onboarding experiences also drive up support costs. Every confusing step generates tickets, calls, and escalations. Reducing effort during onboarding pays off twice: better retention and lower support load.
How to measure it
CES uses a single survey question, typically: "How easy was it to [complete this task]?"
Customers respond on a scale. The two most common formats are:
- 1-7 scale: 1 = "Very Difficult," 7 = "Very Easy"
- 1-5 scale: 1 = "Very Difficult," 5 = "Very Easy"
Formula:
CES = Sum of all responses / Number of responses
Example: Five customers rate a task as 6, 5, 7, 4, and 6 on a 1-7 scale. CES = (6 + 5 + 7 + 4 + 6) / 5 = 5.6
A CES of 5.0 or higher on a 7-point scale generally indicates a low-effort experience. Below 4.0 signals a problem that needs attention.
When to trigger CES surveys
Don't send CES surveys at random. Trigger them right after a specific action:
- After completing account setup
- After finishing the first key workflow
- After contacting support
- After completing an onboarding milestone
Timing matters. Ask within minutes of the task, not days later.
CES vs. NPS vs. CSAT
- CES measures effort on a specific task. Best for pinpointing friction.
- NPS measures loyalty and likelihood to recommend. Best for long-term trends.
- CSAT measures general satisfaction. Best for broad sentiment.
For onboarding, CES gives you the most actionable data. You can tie each score to a specific step and fix what's broken.
How to improve your CES
Reduce the number of steps. Audit your onboarding flow and remove anything that doesn't directly contribute to customer success.
Add clear instructions. Customers shouldn't have to guess what to do next. Visual guides with progress indicators keep them on track.
Automate repetitive tasks. If customers are manually entering data that you could pull from an integration, automate it.
Measure at each milestone. Don't just measure CES once. Measure it at every major onboarding step so you can find exactly where effort spikes.
OnboardingHub includes built-in CES measurement, so you can collect effort scores at each step of your onboarding flow without setting up a separate survey tool. Plans start at $99/month with no per-seat fees.
