Bounce Rate Calculator

How it is calculated

The tool divides single-page sessions by total sessions and multiplies by 100: bounce rate = single-page sessions ÷ total sessions × 100. This is the classic (Universal Analytics) definition of a bounce. The rest is the multi-page share, multi-page rate = 100 − bounce rate, and the multi-page session count is total − single-page sessions. Sessions are counted, so both fields must be whole numbers: a value such as 3150.5 shows no result. Total sessions must be at least 1, and single-page sessions cannot be negative or higher than the total. Both counts must come from the same page, source or time period. Percentages are rounded to two decimals. GA4 counts a bounce as a session that was not engaged (10 seconds or less, no key event and fewer than 2 page or screen views), so a GA4 report gives a different, usually lower, figure; enter its non-engaged sessions instead if you want that version.

Common mistakes

• Counting page views instead of sessions. A bounce is a session with a single page view; entering total page views as the total gives a rate that is far too low.
• Mixing periods or segments, such as single-page sessions for one source and total sessions for the whole site. Both numbers have to come from the same filter.
• Typing the figures with a decimal part or an average. The tool accepts only whole session counts and shows no result for 3150.5, and a single-page count larger than the total is rejected too.
• Treating a high rate as always bad. A page that answers the question fully, like a contact page or a recipe, can have a high bounce rate and still do its job.
• Comparing the result with a GA4 bounce rate. GA4 counts non-engaged sessions, not single-page ones, so the two figures differ; compare like with like.
• Entering the rate you already know in one of the fields. The tool needs two raw counts, so use the session numbers, not percentages.
