What Is CSAT?

Definition

Customer Satisfaction Score (CSAT) measures how satisfied customers are with a specific interaction, product or service, usually via a short “how satisfied were you?” survey. It's expressed as the percentage of positive responses and is best suited to measuring satisfaction at specific touchpoints.

Key takeaways

  • CSAT = % of respondents who rate satisfaction positively (e.g. 4–5 of 5).
  • It's transactional — best tied to a specific interaction or touchpoint.
  • Pair it with NPS (loyalty) and CES (effort) for a fuller picture.

How CSAT is calculated

CSAT = (Positive Responses ÷ Total Responses) × 100

CSAT vs NPS vs CES

CSAT captures satisfaction with a moment; NPS captures overall loyalty; CES captures how hard the customer had to work. They answer different questions — strong CS teams track all three at the right points in the journey.
