What is a CSAT Score?
Last Updated September 28, 2026
A CSAT score, or customer satisfaction score, measures how satisfied customers say they are with a specific interaction or experience. Organizations typically collect CSAT through a short survey and calculate the percentage of positive responses. Because CSAT is usually tied to a recent event, it is especially useful for understanding service quality at the interaction or journey level.
How to calculate a CSAT score
A common calculation is: positive responses divided by total valid responses, multiplied by 100. If 800 customers respond and 640 select one of the positive options, the CSAT score is 80%. Survey scale design matters, so teams should document which responses are treated as positive.
When to use CSAT
- After a customer service interaction
- After onboarding or implementation
- After a purchase or delivery
- After a support case closes
- After self-service completion
- After a significant journey milestone
CSAT vs. NPS vs. customer effort
Why CSAT can be misleading
Survey response bias, low response rates, channel differences, and changes in customer mix can all move CSAT without a true change in experience. A high CSAT score can also coexist with repeat contacts or unresolved problems if only satisfied customers respond.
How to improve CSAT
Use interaction analytics, customer feedback, repeat-contact data, transfer patterns, and journey analytics to understand the reasons behind the score.
- Reduce avoidable transfers
- Improve first-contact resolution
- Give agents faster access to accurate knowledge
- Fix common digital and self-service failures
- Reduce wait and response times where they create friction
- Coach against observable interaction behaviors
- Close the loop on recurring product or policy issues
Use CSAT as part of a broader CX scorecard
