What is Customer Satisfaction Score (CSAT)?

Customer Satisfaction Score (CSAT) is a key metric that measures how satisfied customers are with a product, service, or interaction. Unlike NPS, which predicts loyalty, CSAT focuses on immediate happiness and can be used to quickly identify pain points in the customer journey.

CSAT is usually measured using a simple question:

“How satisfied were you with your experience?”

Responses can be collected using rating scales (stars, hearts, numeric) or opinion scales, making it easy to integrate into your one-question-per-page surveys.

How the CSAT Calculator Works

This CSAT calculator computes your score by averaging all customer responses.

CSAT Formula

CSAT (%) = (Sum of satisfied responses ÷ Total responses) × 100

Where “satisfied responses” usually include the top ratings (e.g., 4–5 on a 5-point scale).

Example:

  • Responses: 5, 4, 3, 5, 4
  • Satisfied responses (4–5): 4
  • Total responses: 5

CSAT = (4 ÷ 5) × 100 = 80%

Higher percentages indicate higher customer satisfaction.

How to Collect CSAT Responses

Use your CSAT question immediately after key interactions for the most accurate feedback. You can leverage your Typeform-style one-question-per-page survey with:
