What Is CSAT?
CSAT (Customer Satisfaction Score) is a metric that measures how satisfied customers are with a specific interaction, product, or service. It is calculated by asking customers to rate their experience on a scale (typically 1-5) and then calculating the percentage who chose the top two ratings (4 and 5).
The formula is: CSAT (%) = (Number of Satisfied Responses / Total Number of Responses) x 100
"Satisfied" means respondents who selected 4 (satisfied) or 5 (very satisfied) on a standard 5-point scale. Responses of 1 (very dissatisfied), 2 (dissatisfied), and 3 (neutral) are not counted as satisfied.
A SaaS company closes 425 support tickets in a month and sends a one-question CSAT survey after each one. They receive 425 responses. Of those, 340 respondents selected 4 or 5. Their CSAT score is (340 / 425) x 100 = 80%.
CSAT Benchmarks by Industry
CSAT scores vary significantly by industry. Businesses with high-touch, personalized service tend to score higher than those in commoditized or high-friction industries. Use the table below to see where your score falls relative to your peers.
| Industry | Average CSAT | Notes |
|---|---|---|
| Financial Advisory | 90% | High-touch, relationship-driven service. |
| Insurance | 78% | Claims processing speed is the biggest driver. |
| SaaS / Software | 78% | Product quality and support speed are key factors. |
| E-commerce | 80% | Delivery speed and return policies drive satisfaction. |
| Retail (Brick & Mortar) | 77% | In-store experience and staff helpfulness matter most. |
| Healthcare | 74% | Wait times and communication affect scores heavily. |
| Banking | 78% | Digital banking features are raising scores industry-wide. |
| Hotels | 76% | Cleanliness and check-in experience are top factors. |
| Airlines | 75% | On-time performance correlates strongly with CSAT. |
| Telecommunications | 68% | Consistently among the lowest due to billing and service issues. |
| Internet Service Providers | 65% | Limited competition and service outages depress scores. |
| Government Services | 65% | Bureaucratic processes and long wait times are persistent issues. |

How to Calculate CSAT
The CSAT formula requires two numbers: the count of satisfied responses and the total number of responses.
CSAT (%) = (Satisfied Responses / Total Responses) x 100
Worked example: An e-commerce company surveys customers after order delivery. In January, they collected 1,200 responses. Of those, 180 selected 5 (very satisfied) and 780 selected 4 (satisfied). The remaining 240 selected 1, 2, or 3.
- Satisfied Responses = 180 + 780 = 960
- Total Responses = 1,200
- CSAT = (960 / 1,200) x 100 = 80%
- Dissatisfied = (240 / 1,200) x 100 = 20%
This means 80% of customers who responded to the survey were satisfied with their delivery experience. The 20% who were not satisfied represent 240 customers whose feedback should be analyzed for patterns.
CSAT vs NPS vs CES
CSAT, NPS, and CES are the three most common customer experience metrics. Each measures something different, and most mature teams use all three at different touchpoints.
| Metric | What It Measures | Question Asked | Best Used After |
|---|---|---|---|
| CSAT | Satisfaction with a specific interaction | "How satisfied were you with [experience]?" | Support tickets, purchases, onboarding |
| NPS | Overall loyalty and likelihood to recommend | "How likely are you to recommend us?" (0-10) | Quarterly relationship surveys |
| CES | Ease of completing a task | "How easy was it to [do X]?" (1-7) | Self-service flows, returns, account changes |
CSAT is the best choice for measuring satisfaction with specific interactions. It tells you whether a customer was happy with a support call, a product delivery, or an onboarding session. The downside is that it captures a snapshot, not a trend. A customer can give you a 5 today and churn next month.
NPS is better for measuring overall brand health and predicting long-term growth. It separates customers into promoters (9-10), passives (7-8), and detractors (0-6). The score ranges from -100 to +100.
CES is the strongest predictor of churn. Research from the Harvard Business Review found that 96% of customers who had a high-effort experience became disloyal, compared to only 9% of those with a low-effort experience.
Why CSAT Matters
CSAT is one of the most direct signals of customer experience quality because it captures feedback while the experience is still fresh. Unlike NPS, which reflects a general feeling about your brand, CSAT ties directly to specific interactions you can improve.
Early churn warning. Customers who rate an interaction as 1 or 2 are significantly more likely to churn within 90 days. Tracking CSAT by cohort lets you identify at-risk customers before they leave and intervene with outreach or a service recovery offer.
Agent and team performance. When you measure CSAT per support agent, per product, or per touchpoint, you can identify exactly where experience breaks down. A support team with an 85% CSAT except for one agent at 55% has a training problem, not a process problem.
Revenue correlation. Bain & Company research shows that a 5-percentage-point increase in customer retention (driven partly by satisfaction) can increase profits by 25-95%. Satisfied customers buy more, buy more often, and cost less to serve because they submit fewer support requests.
Competitive differentiation. In industries where products are similar (banking, insurance, telecom), customer satisfaction is often the primary differentiator. Companies that consistently score 10+ points above their industry CSAT average tend to grow revenue 2-3x faster than their peers.
How to Improve Your CSAT Score
Improving CSAT requires identifying the specific touchpoints where satisfaction drops and fixing the root causes. Generic "delight the customer" initiatives rarely move the needle.
1. Close the loop on every low score. When a customer rates their experience a 1 or 2, follow up within 24 hours. Ask what went wrong and resolve the issue. This single practice can recover 30-50% of dissatisfied customers and often turns detractors into advocates.
2. Reduce first response time. In support interactions, the time to first response is the strongest predictor of CSAT. Zendesk data shows that tickets responded to within 1 hour have a 90%+ CSAT rate, while those with 24+ hour response times drop to 60-65%.
3. Set expectations and meet them. Customers are more dissatisfied by unmet expectations than by slower service. If shipping takes 5-7 days, say 5-7 days. If a support ticket will take 48 hours, say 48 hours. Under-promise and over-deliver consistently.
4. Analyze dissatisfied responses by category. Tag every low-scoring response with a reason code (long wait, wrong answer, product defect, billing error). After a month, you will see clear patterns. Focus your improvement efforts on the top 2-3 categories that drive the most dissatisfaction.
5. Give frontline staff authority to resolve issues. Give support agents authority to issue refunds, credits, or replacements up to a certain dollar amount without manager approval. Every escalation adds friction and delays resolution, both of which hurt CSAT.
6. Improve your survey design. Keep CSAT surveys to one question plus an optional open-text field. Multi-page surveys have lower response rates, and non-responders tend to be more dissatisfied than responders, which biases your score upward. A one-click survey embedded in an email gets 3-5x the response rate of a survey link.
