About this tool

Customer Satisfaction Score (CSAT) is one of the fastest and most direct ways to measure how well you’re meeting customer expectations. Unlike NPS, which gauges long-term loyalty, CSAT captures how satisfied a customer was with a specific interaction — a purchase, a support ticket, a product feature, or an onboarding experience. Our free CSAT calculator turns your raw response data into a clear, percentage-based score in seconds.

CSAT is typically measured on a 1–5 or 1–3 scale, where customers rate their satisfaction with a recent experience. To calculate CSAT, divide the number of satisfied responses (ratings of 4–5 on a 5-point scale) by the total number of responses, then multiply by 100. The result is a percentage — your CSAT score. A CSAT above 75% is generally considered good; above 85% is excellent.

Use this tool after every major customer touchpoint: post-purchase, post-support, post-onboarding, or post-product release. CSAT is a leading indicator — a drop in score often predicts churn before it shows up in your retention data, giving you time to act.

Quick answer

CSAT (Customer Satisfaction Score) is calculated by dividing the number of satisfied responses — typically ratings of 4 or 5 on a 5-point scale — by the total number of responses, then multiplying by 100. The result is a percentage between 0% and 100%. A CSAT score above 75% is generally considered good; above 85% is excellent. CSAT measures satisfaction with a specific interaction, making it different from NPS, which measures overall brand loyalty.

CSAT Calculator — FAQ

What is a good CSAT score?+
A good CSAT score is generally 75% or higher, meaning 75% of respondents rated their experience as satisfying (4–5 on a 5-point scale). Excellent CSAT is 85% or above. Scores below 60% typically signal significant experience gaps that need immediate attention. Benchmarks vary by industry — technology companies often average 78–82%, while retail averages around 74–78%.
How is CSAT calculated?+
CSAT is calculated by dividing the number of satisfied responses (ratings of 4 or 5 on a 5-point scale) by the total number of responses, then multiplying by 100. For example, if 80 out of 100 respondents gave a rating of 4 or 5, your CSAT score is 80%. Our calculator handles this instantly for any scale you use — 1–3, 1–5, or 1–10.
What’s the difference between CSAT and NPS?+
CSAT measures how satisfied a customer was with a specific interaction — it’s transactional and immediate. NPS measures how likely a customer is to recommend your brand overall — it’s relational and long-term. CSAT is better for evaluating support tickets, onboarding sessions, or individual product features. NPS is better for tracking overall brand loyalty. Most customer-centric teams track both.
What scale should I use for CSAT surveys?+
The most common CSAT scale is 1–5 (very dissatisfied to very satisfied), which is the industry standard. A 3-point scale (negative, neutral, positive) works well for quick pulse checks. Avoid using 1–10 for CSAT — it’s often confused with NPS and makes benchmarking harder. When using a 5-point scale, count only ratings of 4 and 5 as “satisfied” when calculating your CSAT score.
How often should I measure CSAT?+
CSAT should be measured immediately after a specific interaction — within 24 hours of a support resolution, purchase, onboarding call, or product release. Tracking CSAT over time (weekly or monthly averages) reveals trends that help you catch experience problems before they escalate into churn. Set up automated post-interaction surveys using onlinesurvey.ai to capture CSAT at every key touchpoint.
