Common questions about the tools
Are the calculators really free?
Yes. Every tool works without a sign-up and without a time limit. The calculation happens entirely in your browser.
Are my inputs stored?
No. Your numbers never leave your browser. They are neither sent to a server nor saved locally — reloading the page resets every calculator.
Which calculator answers which question?
Before you field a survey, the sample size and margin of error calculators help you plan it. Afterwards, NPS, eNPS, CSAT and CES put your results in context, while response rate, p-value and significance support the analysis.
Can I collect these metrics with empirio.ai?
Yes. There are ready-made templates for NPS, eNPS, CSAT and CES. NPS and eNPS are scored automatically in real time; for CSAT and CES you collect the distribution across the steps and work the score out here. Hosted in the EU.
