About the Cost per Acquisition (CPA) Calculator
Cost per acquisition (CPA) shows how much you spend, on average, to generate one desired outcome — a sale, sign-up, lead, or app install — from a specific marketing campaign.
Formula: CPA = Total Campaign Cost ÷ Total Conversions
Unlike CAC, which usually rolls up spend across an entire company or channel mix, CPA is typically tracked at the campaign or ad-set level so marketers can compare which creative, audience, or platform is converting most efficiently.
