CSAT
Customer satisfaction score
Customer satisfaction score measures how satisfied customers are with a specific interaction, product, or experience. Unlike NPS which measures loyalty, CSAT captures satisfaction at a moment in time, making it ideal for evaluating specific touchpoints in the customer journey.

What is CSAT?
Customer satisfaction score (CSAT) measures customer satisfaction with a specific interaction, transaction, or experience. It is typically collected through a short survey asking "How satisfied were you with [experience]?" with responses on a 1-to-5 or 1-to-7 scale.
CSAT differs from NPS in an important way. NPS measures overall loyalty and willingness to recommend. CSAT measures satisfaction with a specific moment or touchpoint. This makes CSAT more actionable for operational improvements because you can tie the score directly to the experience that triggered it.
Common CSAT touchpoints include post-support interaction (after a ticket is resolved), post-purchase (after a customer completes a transaction), post-onboarding (after completing initial setup), feature-specific (after using a particular feature), and periodic check-in (quarterly or annual satisfaction surveys).
CSAT is the most widely used customer experience metric globally. Its simplicity makes it easy to deploy across many touchpoints, and the specificity of each measurement makes it directly actionable. A low CSAT on support interactions tells you exactly where to investigate: support first response time, resolution time, or agent empathy.
How to calculate CSAT
CSAT is calculated by dividing the number of positive responses (typically 4 and 5 on a 5-point scale) by the total responses and multiplying by 100. If 200 customers respond and 160 rate their experience as 4 or 5, the CSAT is 80%.
The scale varies by implementation. A 5-point scale (Very Unsatisfied to Very Satisfied) is most common. Some organisations use a 7-point scale for more granularity or a simple binary scale (satisfied / not satisfied) for maximum simplicity. The choice affects the absolute score but not the trend, which is what matters most.
| Scale type | Positive responses | Pros | Cons |
|---|---|---|---|
| 5-point (1 to 5) | Scores of 4 and 5 | Most common. Easy for respondents. Good balance of granularity. | Top-two-box scoring can overstate satisfaction. |
| 7-point (1 to 7) | Scores of 5, 6, and 7 | More granular. Better at capturing nuance. | More complex. Respondents may cluster in the middle. |
| Binary (thumbs up/down) | Thumbs up | Highest response rates. No ambiguity. | No granularity. Cannot distinguish very satisfied from barely satisfied. |
CSAT in a metric tree
CSAT decomposes into the specific elements of the customer experience that drive satisfaction. For a support CSAT, the drivers are different from a product CSAT or an onboarding CSAT, which is why touchpoint-specific measurement is so important.
The tree shows that overall CSAT is a composite of satisfaction across multiple touchpoints. If overall CSAT is declining, the tree helps you identify which touchpoint is responsible. If support CSAT is strong but onboarding CSAT is weak, the priority is onboarding improvement, not support investment.
This decomposition also prevents the common mistake of over-investing in one area. A team that achieves 95% support CSAT but has 60% onboarding CSAT has diminishing returns on support improvement and massive potential from onboarding improvement.
CSAT benchmarks
| Context | Good CSAT | Excellent CSAT |
|---|---|---|
| B2B SaaS (overall) | 75% to 80% | 85%+ |
| Customer support | 80% to 85% | 90%+ |
| E-commerce (post-purchase) | 75% to 80% | 85%+ |
| Onboarding experience | 70% to 80% | 85%+ |
| Financial services | 70% to 78% | 85%+ |
CSAT is subject to response bias: satisfied customers are less likely to respond than dissatisfied ones (for solicited surveys) or more likely (for post-interaction surveys). Track response rates alongside CSAT to understand how representative the score is.
How to improve CSAT
- 1
Act on feedback immediately
Contact customers who give low scores within 24 hours. Understand their specific issue, resolve it, and feed the insight back to the team responsible. Fast follow-up often converts dissatisfied customers into advocates.
- 2
Measure at the right touchpoints
Send CSAT surveys immediately after the experience you want to evaluate. Delayed surveys capture faded memories, not accurate satisfaction. Keep surveys short: one rating question and one open-ended follow-up.
- 3
Identify and fix systemic issues
Categorise low-CSAT feedback by theme. If the same issues appear repeatedly, invest in fixing the root cause rather than handling each case individually.
- 4
Set expectations accurately
Satisfaction is the gap between expectation and reality. Setting accurate expectations during sales, support, and onboarding prevents the disappointment that drives low scores.
- 5
Empower frontline teams to resolve issues
Support agents who can resolve issues without escalation deliver faster, more satisfying experiences. Give frontline teams the authority and tools to solve problems on the first contact.
Common mistakes with CSAT
Surveying too often
Survey fatigue leads to declining response rates and less reliable scores. Survey at key moments, not after every interaction. Aim for no more than one survey per customer per quarter.
Not acting on the feedback
Collecting CSAT without acting on it is worse than not collecting it at all. Customers who provide feedback and see no change become more dissatisfied. Create a clear process for acting on low scores.
Using CSAT as the only CX metric
CSAT measures satisfaction at a moment. NPS measures loyalty. CES measures effort. Retention measures actual behaviour. Use all four for a complete picture of customer experience.
Comparing scores across different scales
A CSAT of 80% on a 5-point scale is not the same as 80% on a 7-point scale. Ensure you use the same scale consistently and do not compare scores across different survey instruments.

Net Promoter Score
NPS
Product MetricsMetric Definition
NPS = % Promoters - % Detractors
Net Promoter Score measures customer loyalty by asking how likely a customer is to recommend your product or service. It is the most widely used customer experience metric, providing a single number that captures sentiment and predicts growth through word-of-mouth.
Customer Effort Score
CES
Product MetricsMetric Definition
CES = Sum of All Effort Ratings / Number of Responses
Customer effort score measures how much effort a customer had to exert to accomplish a goal with your product or service. Research shows that reducing effort is more predictive of customer loyalty than increasing satisfaction, making CES a powerful complement to NPS and CSAT.
Retention Rate
Product MetricsMetric Definition
Retention Rate = (Users Active at End of Period / Users Active at Start of Period) × 100
Retention rate measures the percentage of users or customers who continue to use your product over a given period. It is the most important growth metric because sustainable growth is impossible when users leave faster than they arrive.
Daily Active Users
DAU
Product MetricsMetric Definition
DAU = Unique Users Who Performed a Qualifying Action in a Single Day
Daily active users measures the number of unique users who engage with your product on a given day. It is the primary engagement metric for consumer and SaaS products, indicating whether your product has become a daily habit for its users.
