A survey should be closed when you have enough responses to answer your research question, your survey period has ended, or you have reached the deadline for using the results. Knowing when to close a survey helps you avoid collecting unnecessary responses and keeps your dataset tied to a clear time period.
There is no single survey closing date that works for every project. A customer feedback survey may only need to stay open for a few days, while an employee survey or research survey may need several weeks. The right timing depends on your target audience, response rate, sample size, and when you need to make a decision.
In Formms you close with Accept responses, Close on a date, or Limit responses under Form settings. People then see your closed message.
1. Close when the decision date hits
If you need results for Monday’s meeting, close Sunday night. Analyze what you have. Waiting for a few more rows rarely changes the call.
2. Close when the event window ends
Post-class, post-event, and receipt surveys go cold after a few days. A close date of 3 to 14 days after the moment is a common band. Shorter is fine for live QR forms.
3. Close when you hit the sample you planned
If you only need 100 completes, set Limit responses to 100. Guidance on sample size: How many responses do you need?. Tools: response rate calculator, confidence interval calculator.
4. Close manually when something changes
Turn off Accept responses if the product shipped, the class was canceled, or the link leaked to the wrong audience. You can turn it back on later.
5. Write a clear closed message
“This survey closed on March 1. Thanks to everyone who replied.” Avoid leaving the default if you promised a specific window.
6. Export before you archive the project
Download CSV from Responses while you still care about the dataset. Closing the form does not delete past answers.

How long should a survey stay open?
The right survey duration depends on your audience and the purpose of the survey. A short event feedback survey may only need a few days, while an employee or research survey may need several weeks to reach enough respondents.
Instead of choosing a fixed number of days, set your closing date around three things:
Your target sample size: Close when you have enough completed responses for your analysis.
Your decision deadline: Close early enough to analyze the results before you need to act on them.
Your response rate: If responses are still arriving steadily, you may need to keep the survey open longer. If responses have slowed significantly, additional collection may add little value.
The goal is not to keep a survey open as long as possible. It is to collect enough useful responses within a defined period to support the decision or analysis the survey was created for.
