Cost per conversion formula
Divide campaign spend by tracked conversions for the same scope.
Use cost per lead when the recorded outcome is a lead rather than a conversion.
Model the target from both directions
A target cost shows the allowable spend for current conversions and conversions required for current spend.
The target is entered by the user and is not a benchmark.
Match attribution and reporting scope
Keep spend, conversion definition, window, currency, and channel scope aligned.
Platform attribution and delayed reporting can change final counts.
Do not confuse conversions with customers
A tracked action may not be a new paying customer.
Use customer acquisition cost for the broader acquired-customer denominator.
Questions, answered.
How do you calculate cost per conversion?
Divide campaign spend by tracked conversions from the same reporting scope.
Is cost per conversion the same as CAC?
No. A conversion can be any tracked action, while CAC uses acquired customers.
What is a good cost per conversion?
There is no universal answer; compare the metric with conversion value, margin, quality, and attribution scope.
