How to use the CSAT calculator

Enter your satisfied responses. These are the people who chose 4 or 5 on a 1 to 5 scale.
Enter your total responses. Count everyone who answered the question, whatever they chose.
Read your score and the working. The sum behind your score appears under it, so you can repeat it in a report.

How do you calculate CSAT?

CSAT is the share of people who say they are satisfied. On the usual 1 to 5 scale, satisfied means 4 ("satisfied") or 5 ("very satisfied"). Answers of 1, 2 and 3 count towards the total only.

CSAT = satisfied responses ÷ total responses × 100

For example, if 200 customers answer and 164 choose 4 or 5, your CSAT is 164 ÷ 200 × 100 = 82%.

What is a good CSAT score?

Scores vary by industry and by what you ask about, so your own trend matters more than any benchmark. As a rough guide:

CSAT	What it means
90% and above	Excellent
80% to 89%	Good
70% to 79%	Fair, with room to improve
Below 70%	Something is getting in the way

CSAT or NPS?

CSAT tells you how people felt about one moment, such as a delivery or a support chat. NPS asks whether they would recommend you, which says more about long term loyalty. Many teams send CSAT after each interaction and NPS a few times a year. If you also run NPS, the NPS calculator works out that score.

How to get more useful CSAT results

Ask straight after the moment you want to measure. A rating sent days later measures something else.
Add one open question. "What could we have done better?" turns a low score into something you can fix.
Keep the scale the same every time. Changing from 1 to 5 to 1 to 10 makes old and new scores hard to compare.

Frequently asked questions

Which answers count as satisfied?

On a 1 to 5 scale, 4 and 5 count as satisfied. On other scales, count the top two answers, such as 6 and 7 on a 1 to 7 scale.

Does a neutral answer count?

A 3 on a 1 to 5 scale counts towards your total responses, but not as satisfied. Lots of neutral answers pull your score down.

Is CSAT the same as the average rating?

No. An average of 4.1 out of 5 and a CSAT of 82% describe the same survey in different ways. CSAT is the share of satisfied people, which is easier to explain and to track.

How many responses do I need?

There is no fixed minimum. With only a few responses, one answer moves the score a lot, so watch the trend as more come in.

Is my data saved?

No. The calculator runs in your browser, and the numbers you enter are not sent anywhere or saved.
