What is a good survey response rate?

It depends on the channel. Internal/employee surveys often reach 30–50%, customer email surveys commonly see 10–30%, and external cold lists can be much lower. Compare against your own past campaigns rather than a single universal benchmark.

How do I calculate response rate?

Divide completed responses by the number of invitations sent, then multiply by 100. For example, 120 responses from 800 invitations is a 15% response rate.

Should I count partial responses?

That's up to your analysis, but be consistent. Many teams count only completed responses in the numerator. Whatever you choose, apply the same rule across campaigns so your rates stay comparable.

How many invitations do I need to send?

Divide your target number of responses by your expected response rate. At a 15% rate, reaching 200 responses requires inviting about 1,350 people. Use the planner above to do this instantly.

How response rate is calculated

Response rate is the share of invited people who completed your survey: Response rate = (completed responses / invitations sent) × 100. If 120 people complete a survey you sent to 800, your response rate is 15%.

Keep the denominator honest. Count only the people who actually received the invitation — remove bounced emails and undeliverable contacts — so your rate reflects real engagement rather than a stale list.

What's a typical response rate?

Rates vary enormously by channel and audience. Internal employee surveys often see 30–50% or higher, email surveys to customers commonly land in the 10–30% range, and cold external lists can fall into the low single digits. Transactional surveys sent right after an interaction usually outperform generic blasts.

Because the range is so wide, the most useful benchmark is your own history. Track the rate for each campaign and watch how subject lines, timing, length, and incentives move it.

How to improve it

Keep surveys short and tell people up front how long they'll take. Send from a recognizable sender, personalize the invitation, and pick a time when your audience is likely to be free. A reminder to non-responders a few days later often recovers a meaningful chunk of additional responses.

Use the planner above to work backwards from the number of responses you need. If your historical rate is 15% and you need 200 responses, you'll want to invite roughly 1,350 people — useful to know before you finalize your list.
