1. What Is CPA?

CPA (Cost Per Acquisition) is a marketing metric that measures the aggregate cost to acquire one paying customer on a campaign or channel level. It is calculated by dividing the total campaign cost by the number of acquisitions.

2. How Does the Calculator Work?

The calculator uses the CPA formula:

Where:

• Campaign Cost — Total cost of the marketing campaign in dollars
• Number of Acquisitions — Total number of customers acquired through the campaign

Explanation: This calculation helps marketers understand the efficiency of their advertising spend in acquiring new customers.

3. Importance of CPA Calculation

Details: CPA is crucial for evaluating marketing campaign performance, optimizing advertising budgets, and determining the return on investment for customer acquisition efforts.

4. Using the Calculator

Tips: Enter the total campaign cost in dollars and the number of acquisitions. Both values must be valid (cost ≥ 0, acquisitions > 0).
