How to use the response rate calculator

Enter your responses. Count the people who finished the survey.
Enter how many people you invited. Use the number you sent the survey to.
Add undelivered invites if you know them. Bounced emails never reached anyone, so they are left out of the rate.

How do you calculate a survey response rate?

Response rate = responses ÷ delivered invites × 100

For example, if you email 500 customers, 20 emails bounce and 86 people answer, your response rate is 86 ÷ 480 × 100 = 17.9%.

Count a response only when someone finishes the survey. If you also want to know how many people started and stopped, that is your completion rate, which you can track separately.

What is a good survey response rate?

It depends on who you ask and how. People who know you well answer more often than people who barely remember you.

Who you survey	What many teams see
Customers, by email	Around 10% to 30%
Customers, right after a purchase or chat	Higher, often 30% or more
Your own employees	Often 50% or more

Treat these as a starting point. The most useful comparison is your rate this time against your rate last time.

How to raise your response rate

Keep it short. Say how long it takes, and make that true.
Ask at the right moment. A survey sent straight after an interaction gets more answers than one sent weeks later.
Make it easy on a phone. Many people open survey links on their phone first.
Send one reminder. A single follow up a few days later often brings a second wave of answers.
Share what you changed. People answer again when they see the last survey led somewhere.

Frequently asked questions

Should I count partial responses?

Count only finished surveys in your response rate. Track people who started and stopped as a separate number, so you can see where they left.

What if I shared the survey with a link instead of sending invites?

Without a known number of invites there is no response rate. Use views instead: responses divided by the number of people who opened the survey gives your completion rate.

Why leave undelivered invites out?

Someone whose email bounced never had the chance to answer, so counting them would make your rate look lower than it is.

Is a low response rate a problem?

Not always. A small, honest sample can still be useful. It matters most when the people who answered are very different from those who didn't.

Is my data saved?

No. The calculator runs in your browser, and the numbers you enter are not sent anywhere or saved.
