Calculating your bounce rate is straightforward once you know the Bounce Rate formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Bounce Rate Calculator.
What is Bounce Rate?
The Bounce Rate calculation tells you your bounce rate from a few simple inputs. The figure you are solving for here is the bounce rate, expressed in percent.
The Bounce Rate formula
The core formula is:
Bounce rate = Single-page sessions (bounces) ÷ Total sessions × 100Here is what each input means:
- Single-page sessions (bounces) — a number. Example: 400.
- Total sessions — a number. Example: 1,000.
How to calculate it step by step
- Write down the single-page sessions (bounces) (for example, 400).
- Write down the total sessions (for example, 1,000).
- Apply the formula above to get your bounce rate.
- Double-check the result with the Bounce Rate Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Single-page sessions (bounces) | 400 |
| Total sessions | 1,000 |
| Bounce rate | 40.00% |
With single-page sessions (bounces) of 400 and total sessions of 1,000, the bounce rate works out to 40.00%.
Example 2
With single-page sessions (bounces) of 800 and total sessions of 1,000, the bounce rate works out to 80.00%.
| Result | Value |
|---|---|
| Bounce rate | 80.00% |
Example 3
With single-page sessions (bounces) of 200 and total sessions of 1,000, the bounce rate works out to 20.00%.
| Result | Value |
|---|---|
| Bounce rate | 20.00% |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
