CPA calculator FAQ
What does CPA mean?
CPA usually means cost per acquisition in advertising. It is the average advertising cost for each defined acquisition or conversion.
Is CPA the same as CPC?
No. CPC measures cost per click. CPA measures the cost of the desired outcome after the click, such as a lead or purchase.
Is a lower CPA always better?
Not by itself. A lower CPA is useful only when the acquired customers or leads have enough value to support the cost.
