Work out bounce rate from single-page sessions and total sessions.
A single-page session is one where the visitor viewed one page and left without going further.
Bounce rate
—
The Bounce Rate Calculator turns single-page sessions and total sessions into a bounce rate instantly, with engaged sessions and the GA4-style engagement rate shown alongside and a note on how to read the result.
Bounce rate measures the share of visits that ended on the page they started on — no second page, no further interaction. It is a blunt instrument, but a bounce rate that jumps after a redesign or a new traffic source is one of the fastest warnings you get.
Enter single-page sessions and total sessions and the bounce rate appears straight away, together with the number of engaged sessions and the engagement rate that GA4 reports in its place. A short note puts the result against the ranges different page types usually see.

Bounce rate = Single-page sessions ÷ Total sessions × 100. 1,420 single-page sessions out of 4,000 is a bounce rate of 35.5%.
It depends heavily on page type. Blog posts and reference pages routinely bounce high because the visitor got what they came for, while multi-step funnels and e-commerce category pages should bounce far lower. Compare a page against its own history rather than a site-wide target.
GA4 leads with engagement rate instead — the share of sessions that lasted at least ten seconds, fired a conversion, or viewed more than one page. Bounce rate in GA4 is simply 100% minus that engagement rate, which is why this calculator shows both.
No. A visitor who lands on your opening-hours page, reads it and leaves has been served perfectly. Bounce rate is worth acting on when it rises unexpectedly or is high on pages designed to lead somewhere else.
