What is Customer Satisfaction Score (CSAT)?

CSAT is a straightforward way to measure how happy customers are with a particular experience, whether that's a support conversation, a purchase, or your product overall. You ask a simple question like "How satisfied were you?" on a rating scale, then turn the share of happy answers into a percentage. Because it's so easy to ask and understand, CSAT is one of the most popular customer experience metrics around.

Where CSAT shines is measuring specific moments. If you want to gauge broader loyalty instead, pair it with your Net Promoter Score. Together they give you both the snapshot and the big picture.

How to calculate CSAT

Count the satisfied responses (typically the top two ratings on your scale), divide by the total number of responses, and multiply by 100.

CSAT = (Satisfied Responses ÷ Total Responses) × 100

On a 1 to 5 scale, ratings of 4 and 5 count as satisfied. So if 80 of your 100 respondents rated you 4 or 5, your CSAT is (80 ÷ 100) × 100 = 80%. This "top-two-box" method is the standard because it counts customers who are genuinely pleased, not just neutral. The calculator above sorts this out automatically from your rating breakdown.

What is a good CSAT score?

A CSAT in the 75% to 85% range is generally considered good, and anything above 90% is excellent. Like most experience metrics, benchmarks vary by industry and channel, so your own trend matters more than any single number. If your score is climbing month over month, you're doing something right.

How to improve your CSAT

Two levers move CSAT more than almost anything else: speed and first-contact resolution. Customers forgive a lot, but they rarely forgive waiting. Answering quickly, resolving the issue the first time, and keeping responses accurate all push satisfaction up. That's why many teams automate their most common questions so answers arrive instantly, freeing agents to handle the trickier cases well. Our guide to successful customer service automation covers how to do this without losing the human touch.

Raise your CSAT with faster support

The quickest path to a higher CSAT is usually a faster, more consistent response.

It handles the repetitive questions on its own and hands off to a human with full context whenever a conversation needs one.

Better still, Chatling automatically collects a CSAT rating after each conversation, so the score you just calculated becomes something you can track and improve continuously, without bolting on another survey tool. You can start free, with no credit card required.

Frequently asked questions (FAQs)

What is CSAT (Customer Satisfaction Score)?

CSAT is a metric that measures how satisfied customers are with a specific interaction, product, or service. You ask something like "How satisfied were you with your support experience?" on a rating scale (often 1 to 5), then express the share of happy responses as a percentage. It is a quick, intuitive read on satisfaction at a moment in time.

How is CSAT calculated?

CSAT is the number of satisfied responses divided by the total number of responses, times 100. On a 1 to 5 scale, "satisfied" usually means ratings of 4 and 5. The formula is CSAT = (Satisfied Responses ÷ Total Responses) × 100. The calculator above does this automatically from your rating breakdown.

What counts as a satisfied response?

On a 5-point scale, the top two ratings (4 and 5) are counted as satisfied. This "top-two-box" approach is the most common convention because it captures customers who are clearly happy, rather than merely neutral. Neutral and negative ratings (1 to 3) are not counted as satisfied.

What is a good CSAT score?

A CSAT score of 75% to 85% is generally considered good, and above 90% is excellent. Benchmarks vary by industry and channel, so the most valuable comparison is your own trend over time. A steadily rising CSAT is a strong signal your experience is improving.

What is the difference between CSAT and NPS?

CSAT measures satisfaction with a specific interaction or moment ("how was this experience?"), while NPS measures overall loyalty and likelihood to recommend ("would you recommend us?"). They complement each other. Many teams track both, using our NPS calculator alongside this one.

How can I improve my CSAT?

Respond faster, resolve issues on the first contact, and keep answers accurate and consistent. Wait time is one of the biggest drivers of dissatisfaction, so reducing it (often with automation that answers instantly) tends to lift CSAT quickly.
