Your company has decided to measure customer experience. Great. But then a common question arises: which metric should you use?

Many organizations are familiar with NPS, others rely on CSAT, and some are starting to explore CES. The challenge is that these metrics are often used interchangeably, even though they answer very different questions.

The truth is that there is no single best metric. There is only the right metric for the right moment in the customer journey.

NPS (Net Promoter Score) measures the customer’s overall perception of your company. The classic question is:

“On a scale from 0 to 10, how likely are you to recommend our company to a friend or colleague?”

NPS is best used when you want to understand the overall relationship between your brand and your customers.

Practical example:
A university may use NPS at the end of a semester to understand how students evaluate their overall experience with the institution.

CSAT (Customer Satisfaction Score) measures satisfaction with a specific interaction.

The typical question is:

“How satisfied were you with this service experience?”

CSAT is ideal for evaluating individual touchpoints in the customer journey.

Practical example:
After a support interaction via phone or WhatsApp, a healthcare provider may send a quick survey to understand whether the customer was satisfied with that specific service experience.

CES (Customer Effort Score) measures how much effort the customer had to make to complete a task or solve a problem.

The typical question is:

“How easy was it to resolve your request?”

CES helps identify friction points in customer processes.

Practical example:
A digital bank may use CES after a customer opens a new account to understand whether the process was simple or required too much effort.

In simple terms:

• NPS: measures loyalty and advocacy. 
• CSAT: measures satisfaction with a specific interaction. 
• CES: measures ease and effort reduction. 

More mature organizations often use all three metrics together. While NPS provides a broad view of customer perception, CSAT and CES help identify which stages of the journey are performing well and which need improvement.

Ultimately, the best metric is the one that helps your company make better decisions. Measuring is important, but acting on the insights is what truly drives results.
