Survey response rate calculator
Measure delivery, start, completion, response and drop-off rates from a survey funnel.
Turn invitation and completion counts into a clear survey funnel: delivery, start, completion and response rates. Use it to compare sends without uploading respondent data.
Response rate uses delivered invitations
Response rate is completed responses divided by delivered invitations. Bounces are excluded when supplied.
Completion rate diagnoses the form
Completions divided by starts isolates abandonment after someone opens the survey.
Frequently asked questions
What counts as a response?
