CSAT, Customer Satisfaction Score, turns a simple post-interaction survey into one number you can track over time. Enter how many respondents chose each rating on a standard 5 point scale and this calculator returns your CSAT percentage, the average rating, and how your result compares to common benchmarks.

How to calculate CSAT

CSAT is the percentage of respondents who rated their experience as satisfied, divided by the total number of respondents, multiplied by 100. On a standard 5 point scale, satisfied means a rating of 4 or 5. If 70 out of 100 respondents picked 4 or 5, your CSAT is 70%.

The formula ignores neutral and negative ratings in the numerator, but they still count in the denominator, which is why a large neutral group can hold your score down even without a single negative response.

What counts as a satisfied response

The standard convention is top two box scoring: on a 5 point scale, only ratings of 4 and 5 count toward the satisfied group. Some teams use a stricter definition and count only the top rating, which produces a lower, more conservative score. Whichever definition you use, stay consistent across surveys so your CSAT trend actually means something.

What is a good CSAT score

Published benchmarks vary by industry, but a CSAT in the 75 to 85 percent range is a reasonable general target for most consumer-facing businesses, with software and retail often landing near the higher end and industries like telecom and utilities typically lower. Treat any external benchmark as a rough reference point, not a target to game, and focus on whether your own score is moving up or down over time.

A rising CSAT usually means retention and referrals are about to follow. If you want more of the right people finding you in the first place, request a free SEO audit and we will show you where the opportunity is.

FAQ

CSAT Calculator: questions, answered

What is a CSAT score?
CSAT, or Customer Satisfaction Score, is a metric from a post-interaction survey that measures how satisfied customers were with a specific purchase, support ticket or experience. It is usually collected on a 1 to 5 scale and reported as the percentage of respondents who chose a satisfied rating.
How is CSAT calculated?
Divide the number of satisfied responses, typically ratings of 4 or 5 on a 5 point scale, by the total number of responses, then multiply by 100. This calculator does that math automatically once you enter how many respondents picked each rating.
What is a good CSAT score?
There is no single universal number, but 75 to 85 percent is a commonly cited general benchmark range across industries. Software, ecommerce and hospitality tend to sit toward the higher end, while sectors like telecom and cable often run lower. Compare your score against your own history first, and industry benchmarks second.
CSAT vs NPS, what is the difference?
CSAT measures satisfaction with one specific interaction, like a support call or a purchase, and is best used right after that moment. NPS measures overall loyalty and the likelihood a customer would recommend your business as a whole, and is usually collected periodically rather than after every touchpoint. Many teams track both.
Can I use a different rating scale?
Yes. If your survey uses a 7 or 10 point scale instead of 5, group the top two ratings as your satisfied count, for example 6 and 7 on a 7 point scale, or 9 and 10 on a 10 point scale, and enter that count and the total into a scale that matches. The underlying formula, satisfied divided by total, stays the same regardless of scale length.
