CSAT calculator

Customer Satisfaction Score (CSAT) measures how satisfied customers are with your product, service, purchase experience, or customer support over a specific period. Calculating this metric allows you to evaluate actual service quality, identify weaknesses in business processes early, and prevent customer churn.

What Is CSAT and Customer Satisfaction Score?

CSAT (Customer Satisfaction Score) is a customer satisfaction metric that reflects the percentage of users who are fully satisfied with their interaction with your product, service, support, or overall company.

How to Calculate CSAT?

To measure it, a short survey is typically used with a rating scale (most commonly from 1 to 5, where 1 means “extremely dissatisfied” and 5 means “very satisfied”).

Divide the number of positive responses (ratings of 4 and 5) by the total number of responses received and multiply by 100%. For example, if 160 out of 200 surveyed customers gave a rating of 4 or 5, your CSAT is 80% (160 / 200 × 100%). Or simply use our CSAT calculator.

Measuring CSAT allows you to systematically evaluate customer service quality, identify weak spots in the service funnel, and address negative feedback in time to prevent customer churn.

What Is Considered a “Normal” CSAT Score?

On average, across the B2C and B2B markets, a CSAT between 75% and 85% is considered a good benchmark. However, blindly comparing your score to a generic market average is inaccurate due to several key factors:

Industry Specifics: In high-expectation or high-stress sectors (e.g., airlines, delivery, or banking), a CSAT of 70% can be a great result. Meanwhile, in niches with simpler user experiences (e-commerce, SaaS), 80–90% is considered the norm.
Touchpoint: A survey sent immediately after a successful purchase usually yields a significantly higher CSAT (85–95%) than one sent after contacting customer support regarding a broken product or a return (60–70%).
Scale Variations: A 1–5 scale is the standard, but some companies use 1–3 or 1–10 scales. This alters what counts as a “positive” rating and affects the final percentage.

What 3 Metrics to Consider When Analyzing CSAT?

To ensure your satisfaction evaluation is objective, looking at a single final number is not enough. Pay attention to the following metrics:

Response Rate: The percentage of customers who complete the survey. If the response rate is below 5–10%, the final CSAT score may be skewed (typically, only highly satisfied or extremely angry customers respond).
Sample Size: The total number of ratings received. Surveying 10 people does not provide a representative picture, whereas a sample size of 100+ responses yields actionable insights.
Share of Critically Dissatisfied Customers (Ratings 1 and 2): Even with a high overall CSAT (e.g., 80%), it is vital to track the percentage of negative ratings. These customers are at high risk of churn and drive negative word-of-mouth.

Common Mistakes When Measuring CSAT

Untimely Surveying: Asking for feedback a week after a purchase is too late. Surveys should be triggered immediately after a transaction or issue resolution.

Overly Long Surveys: If a form contains more than 1–2 questions, the completion rate drops sharply, and answer quality deteriorates.

Ignoring Negative Feedback: Collecting ratings without following up on dissatisfied customers deprives the metric of practical value.

When the CSAT Calculator Will NOT Provide an Objective Picture

Insufficient Responses (Small Sample Size): If you receive fewer than 30–50 responses during a given period, the mathematical calculation of CSAT will carry a high margin of error.
Systemic Outages or Crises: Measuring baseline CSAT during major logistics failures or system outages is counterproductive—you will merely capture a situational anomaly.
Lack of Text Comments: A score on its own does not explain the root causes. Without open-ended feedback fields, you will know what happened, but you won’t understand why.

What to Do to Improve CSAT If Scores Are Low?

Close the Loop: Contact customers who left ratings of 1–3 within a few hours. Resolving the issue promptly often converts a dissatisfied customer into a loyal advocate.

Automate and Speed Up Support: First Response Time (FRT) directly impacts service ratings—faster response times lead to higher satisfaction.

Improve UX and Simplify Processes: Eliminate unnecessary steps during checkout, payment, or reaching out to support.

Train Your Frontline Team: Conduct regular audits of conversations and run empathy training sessions for support operators and sales managers.

Our calculator gives you an accurate benchmark, and we help you achieve these results in practice. If your CSAT is dropping and customers are leaving for competitors, it’s time to optimize your touchpoints and service processes. Entrust customer experience analytics and optimization to our team.

FAQ

Which ratings are considered "positive" when calculating CSAT?

When using a classic 5-point scale, ratings of 4 (“Satisfied”) and 5 (“Extremely Satisfied”) are considered positive.

Ratings 1–3 are treated as neutral or negative and are not added to the numerator in the formula. If you use a 10-point scale, positive ratings are typically considered 9 and 10 (similar to NPS), or 8–10 depending on company methodology.

How Does CSAT Differ from NPS and CES?

CSAT (Customer Satisfaction Score): Measures short-term satisfaction with a specific interaction or transaction (e.g., buying a product or calling support).

NPS (Net Promoter Score): Measures overall brand loyalty and long-term willingness to recommend the company to friends or colleagues.

CES (Customer Effort Score): Evaluates the effort a customer had to exert to resolve an issue or complete a purchase.

What Is Considered a Normal Response Rate for CSAT Surveys?

A Response Rate of 10–25% for email surveys and 20–40% for in-app or SMS surveys (sent right in the application or after a live chat conversation) is considered a good benchmark. If the response rate drops below 5–10%, the CSAT results may be skewed, as only the most emotional customers (either extremely dissatisfied or highly loyal) will take the time to respond.

Коли саме краще надсилати опитування CSAT?

The rating request should be sent immediately after an action is completed (Real-Time Feedback). For example:

After a support ticket is resolved: Within 5–15 minutes.
After an online order: Immediately on the “Thank You” page or right after the product is delivered.

If you send the survey several days or weeks later, the emotional resonance is lost, and the response conversion rate will plummet sharply.

What to Do If a Customer Gives a Low Rating (1–3 Points)?

Implement the Close the Loop rule. Automate notifications for your support team or managers whenever a negative rating is received, and contact the customer within 1–2 hours. Find out the root cause of their dissatisfaction, apologize, and offer a solution (e.g., a bonus, product replacement, or discount). Resolving the issue quickly often turns an unhappy customer into a highly loyal brand advocate.
