What is CPA?

CPA (Cost Per Acquisition) measures how much you spend to acquire one conversion. A conversion can be a purchase, lead, signup, download, or any other valuable action. CPA is crucial for understanding the profitability of your marketing campaigns.

CPA Formula

The CPA formula is:

CPA = Total Ad Spend / Total Conversions

CPA vs CAC: What's the Difference?

  • CPA (Cost Per Acquisition): Cost per conversion action from a specific campaign or channel
  • CAC (Customer Acquisition Cost): Total cost to acquire a new customer across all marketing efforts

What's a Good CPA?

A "good" CPA depends on your business model:

  • E-commerce: CPA should be lower than your average profit margin per sale
  • SaaS: CPA should be recoverable within 3-12 months of subscription revenue
  • Lead Generation: CPA should align with the value of a qualified lead

  4. Test and optimize ad creative continuously
