What is a Response Rate?

Last Updated October 1, 2026

Response rate is a percentage that shows how many eligible recipients responded to a survey, outreach effort or request. In customer experience programs, it is commonly used to understand participation in post-interaction surveys, feedback invitations and other research. Response rate helps evaluate data collection quality, but it should not be treated as proof that the responses represent every customer.

Response rate formula

Response Rate = Number of responses / Number of eligible invitations or opportunities x 100. For example, if 2,000 customers receive a survey invitation and 300 respond, the response rate is 15%. Define eligibility carefully so invalid addresses, duplicate invitations or suppressed contacts are handled consistently.

What affects response rate?

• Channel and device.
• Timing after the customer interaction.
• Survey length and effort required.
• Clarity of the request.
• Customer relationship and interaction outcome.
• Frequency of prior survey requests.
• Privacy and trust.

Response rate vs. completion rate

Response rate measures how many people begin or submit a response relative to invitations. Completion rate usually measures how many people who started a survey finish it. A survey can have a reasonable response rate but poor completion if it is too long or confusing.

Avoid response bias

Customers who respond may have unusually positive or negative experiences, more time or stronger opinions. Compare respondent characteristics with the eligible population and combine survey data with behavioral signals such as repeat contact, complaints and interaction analytics.

How to improve survey response

• Ask shortly after the relevant interaction.
• Keep surveys focused on decisions the organization can act on.
• Use clear, concise language.
• Make the survey mobile-friendly and accessible.
• Avoid excessive survey frequency.
• Explain why feedback is useful and how it will be used.
