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. The engaged share is the rest, engaged rate = 100 − bounce rate, and the engaged 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. The tool uses the plain definition (a session that viewed one page); some analytics tools define a bounce differently, so check which definition your report uses.

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.
• Entering the rate you already know in one of the fields. The tool needs two raw counts, so use the session numbers, not percentages.
