Survey Response Rate Calculator
Enter how many people completed your survey and how many invitations were actually delivered (excluding bounces) to get your response rate.
The formula
Response rate = (completed responses ÷ delivered invitations) × 100
What the result means
The response rate tells you what share of the people you reached chose to answer. Count only delivered invitations — bounced emails and failed sends should be excluded from the denominator.
Response rates vary enormously by audience, channel, relationship and survey length, so avoid comparing against generic benchmarks. A short survey to engaged customers behaves nothing like a cold outreach survey. Low rates also raise the risk of non-response bias: the people who answered may differ systematically from those who did not.
