What is CSAT? Customer Satisfaction Score Definition, Formula & How to Measure
Understanding customer satisfaction is critical for business success. This comprehensive guide explains CSAT—what it is, how to calculate it, and practical strategies to improve your score.
Key Insight: Companies with CSAT scores above 85% achieve 3.2x higher customer retention rates than those below 75% (Qualtrics XM Institute, 2025).
What is CSAT (Customer Satisfaction Score)?
CSAT stands for Customer Satisfaction Score. It measures how satisfied customers are with a product, service, or specific interaction. Companies use CSAT surveys to capture immediate feedback after customer touchpoints.
Key Insight: Unlike annual relationship surveys, CSAT focuses on transactional feedback. It answers: "How satisfied were you with your recent experience?"
Businesses typically measure CSAT using a single question: "How satisfied were you with your experience?" Respondents rate satisfaction on a scale. Common scales include:
- 1-3 (Dissatisfied, Neutral, Satisfied)
- 1-5 (Very Dissatisfied to Very Satisfied)
- 1-7 (Extremely Dissatisfied to Extremely Satisfied)
CSAT provides actionable insights at specific moments. It helps companies understand what drives customer happiness. High CSAT correlates with customer loyalty and retention.
Why CSAT Matters for Your Business
Customer satisfaction directly impacts business outcomes. Satisfied customers spend more and stay longer. They become brand advocates who refer others. CSAT reveals pain points before they escalate.
Business Impact
Companies with high CSAT scores see 2.5x higher revenue growth than competitors with low scores. Customer satisfaction drives sustainable business growth.
CSAT helps teams prioritize improvements. It identifies which interactions matter most to customers. Support teams use CSAT to measure agent performance. Product teams track satisfaction after feature launches. Marketing uses CSAT data to refine messaging.
Real-time CSAT feedback prevents small issues from becoming big problems. It builds trust when companies act on feedback quickly. Customers feel heard when their input leads to visible changes.
CSAT Formula & Calculation Examples
Calculating CSAT is straightforward. The standard formula focuses on satisfied responses:
CSAT Formula
(Number of satisfied customers ÷ Total number of respondents) × 100
"Satisfied customers" typically include those selecting 4 or 5 on a 5-point scale. Some companies use only the top score (5/5) as satisfied. Consistency matters most when tracking over time.
Example Calculation:
- Total survey responses: 200
- Responses of 4 or 5 (satisfied): 150
- CSAT Score = (150 ÷ 200) × 100 = 75%
This means 75% of customers were satisfied with their experience. Track this metric weekly or monthly to spot trends. A rising score indicates improving customer satisfaction.
CSAT vs NPS vs CES: Key Differences
Businesses use multiple metrics to measure customer experience. Each serves different purposes. Understanding when to use each metric is crucial.
| Metric | Measures | Best Used For |
|---|---|---|
| CSAT | Satisfaction with specific interactions | Transactional feedback (support tickets, purchases) |
| NPS | Likelihood to recommend your brand | Overall relationship health and growth potential |
| CES | Ease of completing a task | Process efficiency (onboarding, issue resolution) |
CSAT provides immediate, actionable feedback. NPS predicts growth through advocacy. CES identifies friction in customer processes. Use CSAT for granular touchpoint analysis. Combine all three for a complete customer experience picture.
7 Best Practices for Measuring CSAT
Accurate CSAT measurement requires thoughtful execution. Poor survey design yields misleading data. Follow these proven practices:
- Survey immediately after interactions: Send CSAT surveys within 1 hour of support resolution or purchase completion.
- Keep surveys short: Use 1-3 questions maximum to avoid survey fatigue.
- Use consistent scales: Stick to the same rating scale (e.g., 1-5) across all touchpoints.
- Segment feedback: Analyze CSAT by product line, agent, or channel to uncover specific insights.
- Close the loop: Contact dissatisfied customers within 24 hours to address concerns.
- Track trends: Monitor weekly CSAT movements rather than fixating on daily fluctuations.
- Combine with verbatim feedback: Always include an open-ended follow-up question like "What could we improve?"
Pro Tip: Avoid surveying the same customer multiple times per week. This inflates response fatigue and skews results.
How to Improve Your CSAT Score
High CSAT doesn't happen by accident. It requires systematic action on feedback. Focus on these high-impact strategies:
1. Empower Frontline Employees
Support agents with decision-making authority. Allow them to resolve issues without escalations. Provide ongoing training on empathy and problem-solving. Happy employees create happy customers.
2. Reduce Resolution Time
Customers value quick solutions. Implement knowledge bases for self-service. Use chatbots for simple queries. Set clear service level agreements (SLAs) for response times.
3. Personalize Interactions
Use customer history to tailor conversations. Address customers by name. Reference previous interactions. Personalization makes customers feel valued as individuals.
Real Example
A telecom company reduced average handle time by 30% while increasing first-contact resolution. Their CSAT rose from 78% to 89% in six months.
Always share CSAT results with teams. Celebrate improvements publicly. Create action plans for low-scoring touchpoints. Remember that improvement requires consistent effort across departments.
CSAT Benchmarks by Industry
What constitutes a "good" CSAT score varies by industry. Context matters when evaluating performance. These benchmarks represent 2025 averages:
| Industry | Average CSAT | Top Performers |
|---|---|---|
| E-commerce | 82% | 90%+ |
| Software/SaaS | 85% | 92%+ |
| Telecommunications | 76% | 85%+ |
| Banking/Finance | 80% | 88%+ |
| Healthcare | 88% | 95%+ |
Compare your scores against industry peers. Focus on consistent improvement rather than absolute numbers. A 5-point increase can significantly impact retention and revenue.
"CSAT is the heartbeat of customer experience. It's not just a number—it's a diagnostic tool that reveals where your customer experience strategy is succeeding or failing. Companies that obsess over CSAT trends rather than quarterly averages build lasting customer loyalty."

Frequently Asked Questions About CSAT
What is a good CSAT score?
Most industries consider 80-90% excellent. However, compare against your historical performance first. A score that improves consistently matters more than industry averages.
How often should we measure CSAT?
Measure after every significant customer interaction. Track weekly aggregates to identify trends. Avoid surveying the same customer more than once per month.
Can CSAT predict customer churn?
Yes. Customers rating 1-2 on CSAT surveys are 4x more likely to churn within 90 days. This makes CSAT a leading indicator for retention risk.
Should we use 5-point or 7-point scales?
5-point scales yield higher response rates and clearer segmentation. 7-point scales offer more granularity but increase survey fatigue. Most companies prefer 5-point scales for transactional CSAT.
How is CSAT different from CSI?
CSAT measures satisfaction with specific interactions. CSI (Customer Satisfaction Index) typically refers to an overall brand satisfaction score. CSAT is transactional; CSI is relational.
Final Thought: CSAT isn't just a metric—it's a continuous improvement framework. The most successful companies measure it religiously, act on insights immediately, and close the feedback loop with customers.
Conclusion
CSAT is one of the most powerful tools in the customer experience toolkit. Unlike vanity metrics, it provides actionable insights at the precise moments that matter most to customers. By implementing best practices for measurement, analysis, and improvement, businesses can transform customer satisfaction into sustainable competitive advantage.
Key Takeaway
Focus on the quality of feedback rather than quantity. A small number of deeply insightful responses beats thousands of superficial ratings. The goal isn't just to increase your score—it's to understand why customers feel the way they do.
