About Customer Satisfaction Score Calculator

Satisfaction score is the share of respondents choosing the top satisfaction options. The response rate matters just as much, because low response rates skew towards the very happy and the very angry.

Formula

Satisfaction score

CSAT = satisfied responses / total responses × 100; response rate = responses / surveys sent

  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Figures are estimates based on the inputs given. Marketing performance, platform fees and conversion behaviour vary by audience, channel and season. Use this as a planning guide, not a forecast.
  • This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

Frequently Asked Questions

Why does response rate matter?

A 5% response rate tells you about the extremes, not the middle. Interpret high scores from thin samples cautiously.

How does it differ from the net promoter score?

Satisfaction is transactional and immediate; the promoter score measures overall relationship and advocacy.
