Frequently asked questions
How do I use this calculator?
Enter single-page sessions, total sessions. The result updates automatically. Use Reset to restore the example values.
What method does it use?
Rate = single-page sessions / all sessions × 100. This simple ratio does not implement the GA4 engagement-based definition of bounce rate.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
