Customer Satisfaction Score (CSAT)
Customer Satisfaction Score measures how satisfied customers are with a specific interaction or experience, expressed as a percentage of positive responses.
Customer Satisfaction Score (CSAT) is a transactional metric that measures how satisfied a customer was with a specific interaction, typically expressed as the percentage of respondents who gave a positive rating.
What Customer Satisfaction Score Means in Marketing
CSAT is the most direct measure of whether a single experience met expectations. It is asked immediately after an interaction: a support ticket closure, a product delivery, an onboarding call. The question is simple, the score is easy to understand, and the data arrives while the experience is still fresh.
CSAT differs from NPS in scope and timing. NPS measures the relationship over time. CSAT measures a moment. A brand can have a loyal customer base (high NPS) who finds a specific support process deeply frustrating (low CSAT). Identifying and fixing that frustration is what keeps the NPS high.
For marketing, CSAT matters because post-purchase experience shapes repurchase. A customer who rated their delivery experience 2 out of 5 is less likely to return and less likely to recommend. In D2C brands where repeat purchase is the growth model, CSAT scores on fulfilment and customer service are predictors of revenue, not just satisfaction statistics.
How Customer Satisfaction Score Works
Timing matters. Survey immediately after the interaction, not days later. Satisfaction recall degrades quickly. Automated triggers, a support ticket closed, an order delivered, a call ended, are the standard mechanism.
Keep it focused. Ask about one specific interaction, not the whole relationship. “How satisfied were you with the resolution of your support request?” is actionable. “How satisfied are you with us?” is too broad.
Segment by touchpoint. CSAT by delivery differs from CSAT by support. Track them separately so you can identify which touchpoints are underperforming.
Follow up on low scores. A customer who rates 1 or 2 is at high churn risk. An immediate follow-up call or message to understand what went wrong recovers some of those relationships and produces the clearest insight into what needs fixing.
Customer Satisfaction Score Example
Swiggy tracks CSAT across delivery speed, order accuracy and restaurant quality as separate metrics. A customer who gives a low score for order accuracy triggers a direct compensation and review process. That closed loop, tracking the specific failure, compensating the customer and feeding the issue back to the restaurant, is why CSAT data is operationally useful rather than just a reporting number.
Why Customer Satisfaction Score Matters for Marketers
Marketers fund acquisition and neglect retention. CSAT scores tell you whether the experience you are selling in your ads matches the experience customers actually receive. A high acquisition ROAS combined with a declining CSAT is a sign you are filling a leaky bucket: spending to acquire customers your experience will lose.
Frequently Asked Questions
How is CSAT calculated?
Ask customers to rate their satisfaction with a specific interaction on a scale, typically 1 to 5 or 1 to 10. Count the responses in the top tier (4 and 5 on a 5-point scale, or 9 and 10 on a 10-point scale) as satisfied. CSAT equals the number of satisfied responses divided by total responses, multiplied by 100. A CSAT of 80% means 80 out of every 100 respondents rated the interaction positively. Unlike NPS, CSAT is interaction-specific rather than a relationship-level measure.
When should you use CSAT versus NPS?
CSAT is best for evaluating specific touchpoints: a support resolution, a delivery experience, an onboarding session. It answers 'was this interaction good?' NPS is better for measuring overall relationship loyalty: 'would you recommend us?' Use CSAT at transaction level to diagnose which interactions are working and which are not. Use NPS at relationship level to track whether those interactions are building or eroding long-term loyalty. Most mature CX programmes use both.
What drives CSAT scores down?
Response time (customers waited longer than expected), resolution quality (the problem was closed but not actually fixed), channel friction (customers had to repeat themselves or switch channels), and expectation mismatch (what was promised versus what was delivered). CSAT measures perceived satisfaction, which is always relative to expectation. You can improve CSAT by either improving the experience or accurately setting expectations, since the score reflects the gap between the two.
