Bounce Rate Calculator

Divide single-page sessions by total sessions to get bounce rate, where lower is better.

About Bounce Rate Calculator

The bounce rate is the share of total sessions that sessions that left without interacting represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small. Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.

Formula

Bounce Rate

Bounce Rate = Sessions that left without interacting ÷ Total sessions × 100

Sessions that left without interacting: The subset being measured
Total sessions: The full population it is drawn from

Worked example

With the default values below, Bounce Rate Calculator returns Bounce Rate of 46.32%. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
This is an estimate for general information and not professional financial, tax or legal advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Bounce Rate calculated?

Bounce Rate = Sessions that left without interacting ÷ Total sessions × 100 The bounce rate is the share of total sessions that sessions that left without interacting represents, expressed as a percentage. The same figure is also shown per 1,000 and as a "one in every N" odds statement, which is easier to reason about when the rate is very small.

Why does Bounce Rate matter?

Absolute counts hide scale — a rate normalises the number so you can compare periods, channels or cohorts of different sizes, where lower is better.

What values do I need to enter?

This calculator takes 2 inputs: Sessions that left without interacting, Total sessions. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
