What is Response Rate?
Response rate measures the share of people who complete (or submit) a survey out of everyone invited or reached. It shows how many people engaged with your questionnaire and is used to judge reach and representativeness.
Response rate is calculated by dividing the number of people who returned at least one valid answer by the number of people who were invited or had the opportunity to respond, then expressing that as a percentage. There are common variants: overall response rate (all respondents), completion rate (people who finished every question), and per-language response rates (responses from speakers of specific languages). Response rate helps you understand how well a survey reached and motivated your audience, and whether certain groups were underrepresented.
Usage example
If you emailed a parent list of 1,200 and 300 parents submitted the survey, your response rate is 300 ÷ 1,200 = 25%. If 60 of those responses were in Polish, the Polish-language response rate is 60 ÷ number of Polish-speaking parents invited.
Practical application
Response rate matters because it affects the credibility and usefulness of your findings. Low or uneven response rates can bias results if some communities (for example, non-English speakers) participate much less than others. For teams using Hearo, improving response rates often means removing language barriers (automatic translations, translated invites), making surveys short and mobile-friendly, and letting participants answer in whatever language they prefer — then viewing responses translated back for analysis. Tracking response rate overall and by language helps you spot gaps in engagement and target follow-up or outreach where it’s needed.
FAQ
How exactly do I calculate response rate?
Divide the number of people who submitted at least one valid response by the number of people you invited or reasonably reached, then multiply by 100 for a percentage. If you sent invitations to 800 people and 200 responded, the response rate is 25%. Use consistent rules about what counts as an invitation (unique recipients, not clicks) and what counts as a response (any submission vs only fully completed).
What's the difference between response rate and completion rate?
Response rate measures how many people submitted the survey at all. Completion rate measures how many people finished every required question. A respondent can increase response rate without increasing completion rate if they start but don’t finish the survey.
What is a 'good' response rate?
There’s no universal threshold — acceptable rates depend on context, audience and outreach method. Postal or cold online surveys often see low rates; targeted or well-engaged groups typically deliver higher rates. Instead of a single target, look for stable, representative participation and compare similar projects or language groups to identify gaps.
How does offering multiple languages affect response rate?
Offering surveys in participants’ preferred languages generally increases overall participation and improves representation. Use per-language response rate tracking to spot underrepresented communities, and pair translated invites, simple mobile design and reminders to maximize uptake. With Hearo, you can provide one survey in many languages and monitor responses translated back into your language for easier review.
