NPS vs CSAT vs CES: Choose the Survey That Fits the Decision

By Ulas ArslanPublished 1 Sept 2026Updated 11 Sept 2026

NPS asks about willingness to recommend, CSAT asks about satisfaction and CES asks about the effort involved in an experience. Choose the question based on what your team wants to understand and change. The measures use different scales, so their numeric results cannot be compared as if they were the same score.

Quick answers

What is the difference between NPS, CSAT and CES?: NPS captures stated willingness to recommend. CSAT captures satisfaction with a defined experience. CES captures how easy or difficult an interaction or task felt. Each gives a different piece of customer feedback.
Which survey should a customer success team use?: Use the survey that fits the decision. A relationship review may use NPS, an interaction review may use CSAT and a workflow improvement may use CES. Add a short open question and a clear follow-up process.
Can NPS, CSAT or CES predict whether a customer will renew?: A score alone cannot establish a particular account’s renewal outcome. Check who responded, what experience they rated and what other evidence is available. Treat the response as context for a useful conversation.

Start with the question you need answered

If customers abandon a setup step, ask about that task and the effort it required. If the team wants to review a support interaction, ask about the interaction. A broad relationship question may miss the specific friction you are trying to understand.

Keep the subject and timing clear. A respondent may be happy with the support specialist but disappointed with the product limitation that led them to contact support. Without a defined question, colleagues can read the same score as evidence for different conclusions.

Measure	Useful focus	Example next decision
NPS	Stated willingness to recommend the company or product	Explore the reasons behind the relationship feedback
CSAT	Satisfaction with a named experience	Review what helped or disappointed the customer
CES	Ease or difficulty of a specific task	Remove a step or obstacle that made the task harder

Calculate NPS using response groups

Bain’s NPS scoring method uses a 0–10 recommendation scale. Responses of 9–10 are promoters, 7–8 are passives and 0–6 are detractors. NPS is the percentage of promoters minus the percentage of detractors.

In a fictional survey with 100 valid responses, suppose there are 60 promoters, 25 passives and 15 detractors. NPS is 60% − 15% = +45 points. The 25 passives remain in the denominator even though they are not directly added or subtracted.

The scale runs from −100 to +100. A result of +45 is not a 45% retention rate. Keep the response count, survey wording and audience with the result so a later comparison uses the same basis.

Calculate CSAT with a declared satisfaction threshold

Qualtrics describes a common CSAT calculation using a five-point scale, with responses of 4 and 5 counted as satisfied. Divide those satisfied responses by all valid responses and multiply by 100.

In a separate fictional survey, 80 of 100 respondents choose 4 or 5. CSAT is 80 ÷ 100 × 100 = 80%. This means 80% of respondents selected one of the two satisfied options for the stated experience.

If your survey uses another scale or a different threshold, document it. Do not compare a top-two-box percentage with an average score or with a question that rated a different experience. Those changes affect what the number means.

Define the direction of your CES scale

Qualtrics explains customer effort score as a measure of effort around a particular interaction or task. Survey wording and scale direction matter: “easy” at the high end means a higher score is better, while a high “effort required” score can mean the opposite.

For this illustrative calculation, define 1 as very difficult and 7 as very easy, and report the arithmetic mean. Five fictional responses are 6, 6, 5, 7 and 6. Their sum is 30, so mean CES is 30 ÷ 5 = 6.0 out of 7.

This is one explicitly defined CES format. Keep the original responses and scale labels. Do not convert the result to a percentage or compare it with another team’s CES unless the questions and calculation are compatible.

Check who the result represents

In a B2B account, one user’s response does not necessarily represent every team or the budget approver. Record the respondent’s role and the experience being rated. A stakeholder map helps identify whose perspective is still missing.

Track invitations and valid responses. If 100 people are invited and 20 respond, the scores describe those twenty respondents. The other eighty should not be treated as satisfied, dissatisfied or neutral. Compare response coverage and audience composition when reviewing a trend.

Small samples can move sharply with a few changed responses. Look at the distribution and comments before making a major process change. If the audience, channel or timing changed, note that alongside the score.

Give the feedback a useful destination

Decide who reviews responses and what kinds of feedback require follow-up. A named problem with a current task belongs with someone who can investigate it. A broader relationship concern may need the CSM and the customer owner to clarify expectations.

Use a closed-loop feedback process to record the decision and communicate the outcome. Avoid asking for feedback if the team has no practical way to review or act on it.

Keep surveys as one part of the customer success scorecard. Combine them with agreed outcomes and relevant operational evidence. The useful result is a better understood customer experience and a clear next decision, rather than a single number that claims to explain the entire account.
