Bounce Rate Calculator
Work out your website bounce rate from single-page sessions and total sessions.
This calculator runs entirely in your browser. Nothing you type is uploaded anywhere.
How to use this tool
Open your analytics report and find two numbers for the period you care about. First, the count of single-page sessions, which are visits where the person looked at one page and then left without going anywhere else. Second, the total number of sessions in the same period. Type the single-page sessions into the first field and the total sessions into the second field, then press Calculate bounce rate. The tool returns your bounce percentage along with how many visitors stayed on the site. You can copy the result with one click and paste it into a report.
The formula
The idea is simple. A bounce is a session that ends after a single page with no further interaction, often called a single page drop off. To turn that into a session percentage you divide the bounced sessions by every session that started, then multiply by 100 so the answer reads as a clean bounce percent. A bounce rate of 0 percent means nobody left after one page, and 100 percent means every visit ended on the first page. Most real sites land somewhere in between, and the right target depends heavily on the page type and traffic source.
A real example
Suppose a blog post received 5,000 total sessions last month. Of those, 1,850 visitors read the post and left without clicking anything else, so they count as single-page sessions. The math is 1,850 divided by 5,000, which is 0.37, multiplied by 100. That gives a bounce rate of 37 percent. In plain terms, just over a third of visitors bounced and the remaining 3,150 sessions went on to view at least one more page or take some action.
Common questions
What is a good bounce rate for a website?
There is no single number that fits every site. Content and blog pages often run higher because people read one article and leave, while ecommerce and lead pages aim much lower. Compare a page against its own past performance and against pages with a similar purpose rather than chasing a generic benchmark.
What is the difference between bounce rate and exit rate?
Bounce rate counts sessions that ended after exactly one page with no other activity. Exit rate measures how often a specific page is the last one in any session, even if the visitor viewed several pages first. A high exit rate on a thank-you page can be perfectly healthy, while a high bounce rate on a landing page is usually worth investigating.
Why is my bounce rate so high?
Common causes include slow page load, traffic that does not match the page topic, a single-page layout where everything lives on one screen, or tracking that does not register scrolls and clicks as engagement. Check your fastest traffic sources and slowest pages first to find the single page drop off pattern.
Can the bounce percent be over 100?
No. Single-page sessions are a subset of total sessions, so the result can never exceed 100 percent. If this calculator shows an error, check that your single-page session count is not larger than your total session count, since that points to a data mismatch.
Does this calculator store my numbers?
No. Every calculation happens in your browser using plain JavaScript. The figures you enter are never sent to a server, saved, or shared. You can use it offline once the page has loaded.
