Cost per acquisition
-
CPA = spend / conversions
CPA is acquisition cost for the conversion you define. The cost-per-lead benchmark page is useful context, but CPA and CPL are not identical.
Cost per acquisition, defined.
CPA is the cost of the acquisition event you choose. That event might be a purchase, booked call, lead, subscriber, or another conversion that matters to your funnel.
CPA = spend / conversions
From spend to CPA.
If you spent $600 and generated 20 acquisitions, the math is 600 divided by 20. The result is a $30.00 CPA.
In planning mode, enter a target CPA and conversion count to get the spend ceiling for that goal.
Read CPA against your own economics.
CPA is only good or bad relative to margin, close rate, payback, and customer value. If the conversion is a lead, compare it with lead quality and sales close rate before changing budget.
