Free CSAT Score Calculator

A CSAT score is the percentage of survey respondents who say they are satisfied with a product, support interaction, or service. This calculator turns your survey responses into a CSAT percentage, a 95% confidence interval, and an instant comparison against industry benchmarks for SaaS, retail, telecom, healthcare, financial services, hospitality, ecommerce, and customer support teams.

Pick an input mode, paste your data, and get a clean read on whether your customer satisfaction score is above or below benchmark - plus concrete next steps.

How to use this tool

Calculate your CSAT score in four steps

  1. 1

    Pick the input mode that matches what you have - counts, a 5-point scale split, or raw 1-5 responses.

  2. 2

    Enter your responses. The calculator updates the CSAT score, total response count, and 95% confidence interval live.

  3. 3

    Choose your industry to see how your CSAT compares to the public benchmark for that vertical.

  4. 4

    Review the recommendations and copy a survey question template if you need to launch your next round.

The CSAT formula

CSAT % = (Satisfied responses / Total responses) x 100

On a 5-point scale, "satisfied" counts the 4 (Satisfied) and 5 (Very Satisfied) responses. Neutrals (3) and detractors (1-2) are excluded from the numerator but stay in the denominator. The 95% confidence interval shown is a Wilson score interval - more accurate than a normal-approximation error bar at small sample sizes, which matters for early-stage CSAT programs.

Quick example

100 responses: 82 satisfied, 12 neutral, 6 dissatisfied. CSAT = 82 / 100 = 82%. Above the 78% Customer Support benchmark by 4 points.

Frequently asked questions

What is a good CSAT score?

A CSAT score above 80% is generally considered strong, 70-80% is healthy and roughly average across industries, and below 60% is a warning sign that experience or expectations are misaligned. Compare to your industry benchmark before declaring a number good or bad.

How do you calculate CSAT?

CSAT % = (number of satisfied responses / total number of responses) x 100. On a 1-5 scale, 'satisfied' is the count of 4 (Satisfied) and 5 (Very Satisfied) responses. Neutral and dissatisfied responses are excluded from the numerator but counted in the denominator.

What is the difference between CSAT, NPS, and CES?

CSAT measures satisfaction with a specific interaction or product. NPS (Net Promoter Score) measures overall loyalty by asking how likely a customer is to recommend you. CES (Customer Effort Score) measures how easy it was to get something done. Use CSAT for transactional moments, NPS for relationship health, and CES for friction.

What is a good sample size for a CSAT survey?

For a stable point-in-time read, aim for at least 100 responses per segment per period. Smaller samples make the score swing widely on a few responses. The confidence interval shown by this calculator widens fast under 50 responses, which is your cue to collect more data before acting.

How often should I measure CSAT?

Trigger CSAT immediately after the moment you want to measure - a closed support ticket, a completed purchase, or finished onboarding. Review trends weekly or monthly rather than reacting to single-day changes, and segment the score by channel, product area, or customer tier so the average does not hide problems.
