What is the difference between NPS and CES?

NPS measures overall loyalty and likelihood to recommend on a 0–10 scale, usually at the relationship level. CES measures how easy a specific interaction was, on an ease or agreement scale, right after that interaction. They answer different questions.

Is NPS or CES better?

Neither is universally better. NPS is best for tracking loyalty over time and advocacy; CES is best for removing friction from a specific journey. The right choice depends on the decision you need to make.

Can I use NPS and CES together?

Yes, and many teams do. Relationship NPS on a fixed schedule tracks overall loyalty, while CES after key interactions keeps individual journeys smooth. Together they give a fuller picture than either alone.

What scale does each metric use?

NPS uses a 0–10 likelihood-to-recommend scale grouped into promoters, passives and detractors. CES typically uses a 1–5 or 1–7 ease or agreement scale about how easy a task was.

Which metric should a support team track?

Support teams usually favor CES because it measures the ease of a specific, recent interaction and reacts quickly to process changes. NPS is more often owned at the company or account level.

Does low effort guarantee high loyalty?

Not by itself. Reducing effort removes a major cause of frustration and churn, which helps loyalty, but loyalty also depends on product value and the overall relationship — which is what NPS captures.

How is each score calculated?

NPS is the percentage of promoters (9–10) minus the percentage of detractors (0–6). CES is usually the average rating or the share of respondents who found the task easy. You can compute both with the NPS calculator and the CES calculator.

Should NPS and CES be reported together?

You can present them side by side, but keep them as separate metrics on separate scales rather than combining them. Averaging different metrics hides the specific signal each one provides.

NPS vs Customer Effort Score (CES): Which to Use When

Net Promoter Score (NPS) and Customer Effort Score (CES) are two of the most common customer metrics, and teams often treat them as interchangeable. They are not. NPS measures overall loyalty; CES measures how easy a specific interaction was — and each answers a different question.

This guide defines both, compares them side by side, shows example questions, and explains when to use each or both together. For the full method behind loyalty measurement, see the complete Net Promoter Score guide.

Definitions

Net Promoter Score (NPS)

NPS measures loyalty by asking how likely a customer is to recommend your company on a 0–10 scale. Respondents are grouped into promoters (9–10), passives (7–8) and detractors (0–6), and the score is the percentage of promoters minus the percentage of detractors. It usually reflects the overall relationship. Calculate it with the NPS calculator.

Customer Effort Score (CES)

CES measures how easy it was to get something done — resolve an issue, complete a purchase, finish onboarding. It typically asks respondents to agree or disagree that the task was easy, and is scored as the average rating or the share of low-effort responses. It is scoped to a single interaction. Calculate it with the CES calculator.

Side-by-side comparison

	NPS	Customer Effort Score (CES)
What it measures	Loyalty and likelihood to recommend	How easy an interaction was
Typical scale	0–10 recommendation	1–5 or 1–7 ease/agreement
Time horizon	The overall relationship	A single, recent interaction
Best moment to ask	Periodically, relationship-level	Immediately after the interaction
Score format	% promoters − % detractors	Average score or % low-effort
Best for	Tracking loyalty trends over time	Removing friction from a specific journey
Predicts	Advocacy and long-term growth	Repeat purchase and churn risk from friction

Question examples

The wording makes the difference in intent clear:

NPS: How likely are you to recommend us to a friend or colleague? (0 = Not at all likely, 10 = Extremely likely)

CES: To what extent do you agree — [Company] made it easy for me to resolve my issue. (Strongly disagree → Strongly agree)

NPS asks about your company as a whole; CES asks about one task the customer just completed. Pair either with an open-ended 'why' so the score comes with a reason you can act on.

When to use NPS

You want one recurring health metric for the overall customer relationship.
You need to compare loyalty across cohorts, segments or time periods.
You are tracking advocacy — referrals, reviews and word of mouth.
You are reporting a single, widely recognized loyalty number to leadership.

To act on NPS results, break the score down by group in detractor analysis and follow the steps in how to improve NPS.

When to use CES

You are optimizing a specific journey — support, checkout, onboarding, self-service.
You want fast, actionable feedback on a single interaction that just happened.
You suspect friction is driving frustration or churn and want to locate it.
You need a leading indicator that moves quickly after you change a process.

Effort is a churn signal

High effort in a key interaction is one of the strongest predictors of frustration and defection. CES is the fastest way to catch a broken step before it shows up in your NPS or your cancellation numbers.

When to use both together

NPS and CES are complementary, not competing. Many teams run relationship NPS on a fixed schedule to watch overall loyalty, and CES right after key interactions to keep individual journeys smooth. Together they show whether easy interactions are adding up to a loyal customer base.

Use CES to fix friction in the moments that matter, then watch whether NPS rises over the following quarters.
When NPS dips, use CES data to check whether a specific high-effort journey is dragging it down.
Keep the two streams separate in reporting — they are different metrics on different scales.

Pair every score with a 'why'

Whichever you use, always add an open-text follow-up. The number tells you where you stand; the comments tell you what to fix. AI theming makes reading those comments cheap even at high volume.

You can build either survey from ready-made designs — the NPS survey template — or describe your goal to create your survey with AI, which will generate the right questions and follow-ups for the metric you choose.
