Frequently Asked Questions
What's a good CPA?
A good CPA is one that's lower than your customer lifetime value (LTV) and allows for profitable growth. As a rule of thumb, aim for a CPA that's 1/3 or less of your LTV.
CPA vs CAC: What's the difference?
CPA (Cost Per Acquisition) typically refers to the cost of a single conversion from a specific campaign. CAC (Customer Acquisition Cost) includes all marketing and sales costs divided by new customers acquired.
How do I set a target CPA?
Start by calculating your customer lifetime value (LTV) and determine your target profit margin. If your LTV is $200 and you want a 50% margin, your max CPA should be $100.
What is CPA?
CPA (Cost Per Acquisition or Cost Per Action) measures how much you spend to acquire one customer or conversion. It's one of the most important metrics for measuring campaign profitability and efficiency.
How to Calculate CPA
CPA = Total Campaign Cost / Total Conversions
Example: If you spend $5,000 and get 100 conversions:
CPA = $5,000 / 100 = $50.00 per conversion
