What is a Good CPA?
A “good” CPA depends on industry, product price, and platform. For example:
E-commerce: $20 – $50
Finance/Insurance: $100 – $250
SaaS (Software as a Service): $50 – $150
Mobile Apps: $2 – $10
A good CPA is one where the customer lifetime value (CLV) is higher than the acquisition cost.
CPA vs CPC vs CPM
To understand CPA better, here’s a comparison with other ad metrics:
CPM (Cost Per Mille): Cost per 1,000 impressions (visibility).
CPC (Cost Per Click): Cost per individual click (traffic).
CPA (Cost Per Acquisition): Cost per conversion (sales/leads).
CPA is the most performance-focused metric since it tracks actual results.
