Bounce Rate Calculator

Find the share of sessions that leave after a single page. Enter total sessions and bounced sessions to get bounce rate, engagement rate, and how it compares to a prior period and a target.

Quick Facts

Formula
Bounce Rate = Bounced Sessions ÷ Total Sessions × 100
A bounce is a single-page session with no further interaction — no second pageview, click, or engagement event.
Related metric
Engagement Rate = 100% − Bounce Rate
Platforms such as GA4 report engaged sessions directly and derive bounce rate as the complement of that figure.

What this calculator does

Bounce Rate Calculator applies the standard web analytics formula — bounced sessions divided by total sessions, times 100 — to tell you what share of visits left after viewing a single page with no further interaction. Enter your session counts to get the bounce rate, its complement (engagement rate), and how the current figure compares to a prior period and a target you set.

The formula

Bounce Rate = (Bounced Sessions ÷ Total Sessions) × 100. A bounced session is one where the visitor viewed exactly one page and triggered no additional pageview, click, or engagement event before leaving. This is a straightforward ratio — the accuracy of the result depends entirely on how your analytics tool defines and counts a "bounce," since different platforms (and different tracking configurations) can classify borderline sessions differently.

Getting accurate results

  • Use the same date range and segment for both total sessions and bounced sessions — mixing a filtered view with an unfiltered total is the most common source of errors.
  • Confirm whether your analytics platform counts scroll depth or time-on-page as an "engagement" event — that setting changes what counts as a bounce.
  • Bounced sessions can never exceed total sessions; if your source report shows otherwise, re-check the segment or date filter before trusting the number.

Interpreting the output

A lower bounce rate generally means more visitors are exploring beyond the entry page, but the "right" number is highly page-dependent — a single-page blog post or a contact page with a phone number naturally bounces more than a multi-step product catalog. Comparing your current rate against your own prior period and a target you set is usually more informative than comparing against a generic industry figure.

Next steps

  • Record the date range and segment alongside the result so the number can be reproduced later
  • Break the calculation down by landing page or traffic source to find where bounces concentrate
  • Re-run after any change to page speed, content, or navigation to see whether the change moved the rate

Frequently Asked Questions

What is the formula for bounce rate?
Bounce Rate = (Bounced Sessions ÷ Total Sessions) × 100. A bounced session is one where the visitor viewed a single page and left without any further interaction (no second pageview, click, or engagement event).
What counts as a bounce versus an exit?
An exit is simply the last page viewed in any session, even a long multi-page visit. A bounce is specifically a single-page session with no additional interaction. Every bounce is an exit, but not every exit is a bounce.
What is a good bounce rate?
There is no universal target since it depends heavily on page type: single-page content like blog posts and landing pages naturally runs higher than multi-step sites like e-commerce checkouts. Comparing your rate against your own historical trend and a target you set is generally more useful than chasing a fixed industry number.
How is engagement rate related to bounce rate?
Engagement Rate = 100% − Bounce Rate. Analytics platforms such as GA4 report engaged sessions directly and derive bounce rate as the complement of that figure.
