How to Calculate Website Bounce Rate
Bounce rate is one of the most misunderstood yet critical metrics in digital marketing and SEO. It represents the percentage of visitors who enter your site and then leave ("bounce") rather than continuing to view other pages within the same site.
This calculator helps you determine the bounce rate for a specific page or your entire website based on raw session data. Understanding this metric is the first step toward improving user engagement and conversion rates.
The Bounce Rate Formula
The mathematical formula for calculating bounce rate is straightforward:
Total One-Page Visits (Bounces): The number of sessions where a user viewed only a single page and triggered only a single request to the Analytics server.
Total Entrance Visits: The total number of sessions that began on the site/page during the selected time period.
Interpreting Your Results
Is your bounce rate good or bad? The answer depends heavily on the type of website you run. A blog might naturally have a high bounce rate because users come to read a specific article and then leave. An e-commerce checkout page should ideally have a very low bounce rate.
Bounce Rate Range
Interpretation
Likely Context
25% or lower
Suspiciously Low
Check for duplicate analytics code or technical errors.
26% – 40%
Excellent
Highly engaging content or well-designed landing pages.
41% – 55%
Average
Standard performance for most business websites.
56% – 70%
High
Common for blogs and news sites, but may indicate issues for B2B sites.
70% or higher
Very High
Bad UX, slow loading, or irrelevant traffic sources (except for blogs).
Why is my Bounce Rate so high?
If your calculator result is higher than industry standards, consider investigating these common causes:
Slow Page Load Speed: If your site takes more than 3 seconds to load, users will leave before seeing the content.
Misleading Title Tags/Meta Descriptions: Users expect one thing based on search results but find something else on the page.
Poor Mobile Optimization: A bad experience on mobile devices will drive away a huge portion of traffic.
Intrusive Pop-ups: Aggressive ads or modals immediately upon entry frustrate users.
Single-Page Content: Sometimes a user finds exactly what they need (e.g., a phone number) and leaves. This is a "good" bounce.
Bounce Rate vs. Engagement Rate (GA4)
With the shift to Google Analytics 4 (GA4), the industry is moving toward "Engagement Rate." Engagement Rate is essentially the inverse of Bounce Rate. If your Bounce Rate is 60%, your Engagement Rate is roughly 40%. GA4 defines an engaged session as one that lasts longer than 10 seconds, has a conversion event, or has at least 2 pageviews.
