The Cost Per Conversion formula
Cost Per Conversion = Spend ÷ Conversions
A conversion can be any tracked action — a sign-up, a download, a purchase. This divides total spend by however many of those actions happened, giving a single blended cost figure across a campaign.
Example
A $5,000 campaign drove 250 tracked conversions.
$5,000 ÷ 250 = $20 per conversion

What is the formula behind the Cost Per Conversion Calculator?
Cost Per Conversion = Spend ÷ Conversions. A conversion can be any tracked action — a sign-up, a download, a purchase. This divides total spend by however many of those actions happened, giving a single blended cost figure across a campaign.
How do I calculate cost per conversion?
Divide total campaign spend by tracked conversions for the same reporting period and attribution definition. For example, 400 spent on 20 conversions gives 20 per conversion. If there are no conversions, report no conversions rather than a cost of zero.
Is cost per conversion the same as customer acquisition cost?
Not always. Cost per conversion depends on the tracked action and spend entered. Customer acquisition cost uses new paying customers and the acquisition costs included in your accounting definition. A lead conversion is not yet a customer.
