CPA Calculator FAQ
What is the difference between CPA and CAC?
CPA is usually campaign-specific cost per acquisition, while CAC can include broader sales and marketing costs.
Is lower CPA always better?
Not necessarily. A higher CPA may still be acceptable if retention, margins, or LTV are strong.
Can conversions be zero?
No. The calculator requires at least one conversion because dividing by zero would be invalid.
Should I compare CPA with CLV?
Yes. Comparing acquisition cost against customer lifetime value is one of the most useful ways to judge efficiency.
