How to Calculate Response Rate for Surveys
Calculating your survey response rate is a fundamental step in determining the validity and reliability of your data. A response rate represents the percentage of people who completed your survey out of the total number of people you attempted to contact.
The Basic Formula: Response Rate = (Number of Responses / Total Invitations Sent) × 100
Understanding the Metrics
To use the calculator above effectively, you need three key pieces of data:
Total Invitations Sent: The entire list of individuals included in your sample distribution (email list size, mailers sent, etc.).
Total Responses Received: The count of valid, completed surveys returned to you. Partially completed surveys are usually excluded unless defined otherwise in your methodology.
Bounced / Undeliverable: This is crucial for calculating the Adjusted Response Rate. If an email bounces or a letter is returned as "return to sender," that individual never had the opportunity to respond. Removing them from the denominator gives a more accurate picture of engagement.
Standard vs. Adjusted Response Rate
The calculator provides two outputs:
Standard Response Rate: This is the raw calculation. It includes everyone you tried to contact, even if the message never reached them. This is often used for evaluating the quality of a contact list.
Adjusted Response Rate: This calculation subtracts bounced or undeliverable invitations from the total. It measures the engagement of people who actually received the survey.
