# Survey response rate calculator

Measure delivery, start, completion, response and drop-off rates from a survey funnel.

Invitations sent

Bounced

Survey starts

Completed responses

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?

This calculator treats completed submissions as responses. Use starts separately to expose drop-off.

Should bounces be excluded?

Yes. A person who never received the invitation had no opportunity to respond.
