Customer satisfaction score

Tracking customer satisfaction (CSAT) score provides organizations early visibility into where customers experience friction or value gaps that may lead to escalations or churn. CSAT is one of the most widely used customer satisfaction metrics, frequently used alongside Net Promoter Score (NPS) and customer effort score (CES).

Learn what CSAT is, what it actually measures, and how to calculate it.

What is CSAT?

CSAT is a simple metric organizations use to quantify how satisfied a customer is with a specific product, service, or support interaction. It’s typically measured through short, post-interaction customer surveys.

The goal is to take a quick pulse on the customer’s short-term satisfaction rather than long-term loyalty. But when you pair it with other indicators like NPS and CES, CSAT scores provide valuable insight into the overall customer experience.

Both B2B and B2C organizations use CSAT to identify acute points of friction in the customer journey. In B2B environments, operations teams use CSAT in customer service to:

• Predict operational risk: Low CSAT often precedes spikes in support requests, complaints, and renewal resistance. It gives teams an early warning signal so they can intervene before the problem becomes costly for the business.
• Expose workflow failures: In complex B2B relationships, dissatisfaction frequently points to breakdowns in broader processes, like onboarding or cross-team communication handoffs.
• Reduce cost-to-serve: High CSAT is usually linked to fewer escalations and smoother collaboration, reducing support hours and rework.
• Improve renewal and expansion forecasting: CSAT trends help account teams identify stable accounts and those at risk so they can determine where to focus resources.

How is CSAT measured?

Organizations typically measure CSAT through a short survey shared with customers immediately after an interaction.

The survey usually asks a single question: “How satisfied are you with your experience today?” Customers respond on a 1–5 or 1–10 scale, and teams track the percentage of responses that fall into the “satisfied” range.

In B2B environments, businesses typically send CSAT surveys to customers right after support interactions, onboarding milestones, or service touchpoints. Because each response is tied to a specific experience, teams can easily identify which interactions yield low scores.

These trends then inform deeper customer feedback efforts to determine the root causes of dissatisfaction and how to address them.

How to calculate CSAT

A CSAT score is calculated by finding the percentage of customers who select a positive rating on a post-interaction survey.

Teams first quantify each customer’s satisfaction level, commonly using simple scales like the following:

• 1–5
• 1–10
• Very satisfied to very dissatisfied

This structure makes it easy for customers to respond and for teams to tally results. The CSAT formula is straightforward:

CSAT = (Positive responses / Total responses) × 100

The result is a clear percentage that reflects how well the interaction met customer expectations.
