Formula & Mathematical Methodology

CPA = Total Ad Spend / Total Conversions

Divide total advertising spend by the number of completed conversions or acquisitions.

Scenario: You spend $2,500 on Google Search Ads and acquire 50 paying customers.

CPA = $2,500 / 50 = $50.00 per customer.

Enter your total ad budget and the number of acquired conversions to get your precise CPA.

Compare CPA against your Customer Lifetime Value (LTV). If CPA is $50 and LTV is $250, your acquisition economics are highly profitable.
Segment CPA by device, location, and audience demographic to reallocate budget to high-efficiency pockets.
