Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Bounce rate | Engaged sessions share |
|---|---|---|
| 300 of 1,000 sessions | 30.00% | 70.00% |
| 650 of 1,000 (blog) | 65.00% | 35.00% |
| 120 of 800 (funnel) | 15.00% | 85.00% |
| 4,500 of 6,000 | 75.00% | 25.00% |
How This Calculator Works
Enter the number of single-page sessions and the total sessions in the same period. The calculator divides one by the other and multiplies by 100 to give the bounce rate, with the engaged-session share shown alongside.
The Formula
Part as a Percentage of a Whole
Part is the portion, Whole is the total it belongs to
Worked Example
A site with 300 single-page sessions out of 1,000 total has a 30% bounce rate, with 70% engaged sessions. Content-focused sites (blogs, news) routinely run 60% to 80% — a high bounce there is not always bad, since readers often get what they came for on one page. Funnels, landing pages, and ecommerce sites with a 60%+ bounce rate usually have problems.
Key Insight
Bounce rate's meaning depends entirely on what the page is trying to do. A blog post with a 75% bounce rate may have delivered exactly what the reader needed; a checkout page with the same rate is bleeding revenue. Context matters more than the number itself — and that's why GA4 moved away from bounce rate as a default metric toward 'engaged sessions'.
Frequently Asked Questions
How is bounce rate calculated?
Divide single-page sessions by total sessions, then multiply by 100. 300 single-page sessions out of 1,000 total is a 30% bounce rate.
What is a good bounce rate?
Depends entirely on page intent. Blogs and content sites commonly run 60% to 80% (often fine). Funnels, landing pages, and ecommerce should usually sit below 60%. Compare against pages of the same type.
Why did GA4 drop bounce rate as a default?
Because single-page sessions are not always bad. GA4's default engagement metric is 'engaged sessions' — sessions lasting 10+ seconds, with a conversion, or 2+ page views — which captures meaningful engagement better than bounce rate alone.
How can I lower bounce rate?
For funnels: faster load times, clearer headlines, stronger calls to action, better internal links. For content: related-post widgets, sticky navigation, embedded media. Match the page to the intent of the traffic coming to it.
Does bounce rate affect SEO?
Not directly as a ranking signal, but it correlates with what does matter — dwell time, return visits, and content satisfaction. A persistently high bounce rate on pages targeted for specific queries often signals a mismatch worth fixing.

Methodology & Review
Bounce rate is single-page sessions divided by total sessions, multiplied by 100. The complement is the engaged-session share. Definitions vary across analytics platforms — GA4 uses 'engaged sessions' as the inverse, defined as sessions lasting 10+ seconds, with a conversion, or with 2+ page views.
