4.00% is the example result. The converted events must belong to the eligible visitor or prospect population. Decide whether repeat events or unique people are counted.

Result = (([Conversions]) ÷ ([Visitors or prospects])) × 100
Purpose

Measure how often the chosen audience completes a defined conversion. Enter a numerator and denominator from the same funnel step.

Choose the event and audience first

Conversion rate divides conversions by visitors or prospects and expresses the fraction as a percentage. A session-based rate and a person-based rate can differ even when both reports are correct.

When to use this result

Use it to assess a form or funnel change. Keep the traffic source, event definition and observation window comparable. The rate alone does not establish why performance changed.

Check before you act

Count repeat events consistently. A zero denominator is undefined; a value above 100% may mean you counted multiple events per person.

Example with the supplied inputs

Conversions: 120; Visitors or prospects: 3000. Result: 4.00%. The values are illustrative.

Compare one changed input

Conversions changes from 120 to 132. The result becomes 4.40%. All other inputs remain fixed.

Calculation rule

Formula

Result = (([Conversions]) ÷ ([Visitors or prospects])) × 100

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
Conversions 120 Use the source quantity represented by conversions. Keep the counted population fixed and avoid mixing a unit value with a period total.
Visitors or prospects 3000 Use the source quantity represented by visitors or prospects. Keep the counted population fixed and avoid mixing a unit value with a period total.

Output: 4.00% is the example result. The converted events must belong to the eligible visitor or prospect population. Decide whether repeat events or unique people are counted. Use the formula to distinguish a cash amount, count, percentage or ratio.

How to use the page

STEP 01

Collect the inputs

Gather Conversions, Visitors or prospects. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change Conversions on its own, keeping the other inputs fixed. Read both results before changing another assumption.

Worked example

With the example inputs listed above, the result is 4.00%.

Change Conversions from 120 to 132 while keeping every other value fixed. The result becomes 4.40%. This comparison isolates that input; it does not forecast how other variables will respond.

Check the stated formula, units and limits before using the result in a decision.

Calculation and source notes

Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
