Quick answer
A bounce rate calculator divides bounced sessions by total sessions and multiplies by 100. 4,300 bounces from 10,000 sessions is a 43% bounce rate. In GA4 a bounce is a session that was not engaged, and engagement rate is simply 100% minus bounce rate. Judge it by page type, not one target.
What is a bounce rate calculator?
A bounce rate calculator is a tool that shows the share of sessions that left without engaging. The formula is bounce rate = bounced sessions ÷ total sessions × 100, and in GA4 engagement rate = engaged sessions ÷ total sessions × 100, which equals 100% minus bounce rate.
How do you use the Bounce Rate Calculator?
- Choose the definition you are using: GA4 or Universal Analytics style single page sessions.
- Enter total sessions for the page or site and period.
- Enter bounced sessions: sessions that were not engaged in GA4, or single page sessions in the older model.
- Optionally add total page views to see views per session.
- Read the bounce rate, engagement rate and breakdown.
How do you calculate bounce rate?
Bounce rate = bounced sessions ÷ total sessions × 100, so 300 bounces from 1,000 sessions is 30%. In GA4 a bounced session is one that was not engaged, as described in Google's engagement rate and bounce rate guide. Use the same date range and filters for both numbers.
What counts as an engaged session in GA4?
GA4 counts a session as engaged if it lasts longer than 10 seconds, has a key event, or has at least two page or screen views. Every session that meets none of these conditions counts as a bounce, so bounce rate is the inverse of engagement rate.
What is a good bounce rate?
A good bounce rate depends on the page type and intent, so compare similar pages rather than chasing one number. A contact page or a quick answer article can satisfy users in one view, while a product category page with a very high bounce rate usually needs work.
Quick reference
| Total sessions | Bounced sessions | Bounce / engagement |
|---|---|---|
| 1,000 | 250 | 25% / 75% |
| 5,000 | 2,000 | 40% / 60% |
| 10,000 | 4,300 | 43% / 57% |
| 2,400 | 1,560 | 65% / 35% |
| 800 | 640 | 80% / 20% |
Worked example
Example
Example: a blog gets 10,000 sessions in GA4 and 5,700 of them are engaged, so 4,300 are bounces. Bounce rate = 4,300 ÷ 10,000 × 100 = 43%, and engagement rate = 100% minus 43% = 57%. With 26,000 page views, views per session = 26,000 ÷ 10,000 = 2.6.
Frequently asked questions
Is bounce rate a Google ranking factor?
Google has not said that analytics bounce rate is a ranking factor, and many sites do not use Google Analytics at all. Treat bounce rate as a signal about your page and traffic quality, not as a direct SEO score.
Why is GA4 bounce rate different from Universal Analytics?
Universal Analytics counted single page sessions as bounces, even if the visitor read for ten minutes. GA4 counts a bounce only when the session was not engaged, so GA4 bounce rates are often lower for content sites.
How do I find bounce rate in GA4?
Bounce rate is not shown in every GA4 report by default. Customise a report such as Pages and screens and add the Bounce rate or Engagement rate metric, or build an exploration that includes sessions and engaged sessions.
How can I reduce bounce rate?
Match the page to the search intent, answer the main question early, speed up loading, use clear headings, add relevant internal links and calls to action, and make the page easy to use on mobile so visitors engage further.
Can bounce rate be 0%?
A 0% bounce rate is almost always a tracking error, such as the analytics tag firing twice or an automatic event marking every session as engaged. Check your tag setup if a page suddenly shows a near zero bounce rate.
What is engagement rate?
Engagement rate is the percentage of sessions that were engaged. In GA4 it equals engaged sessions divided by total sessions times 100, and it is the exact opposite of bounce rate, so the two always add up to 100%.
