CPA Calculator – Cost per Acquisition
Find out exactly how much you’re paying, on average, to acquire each new customer or lead from a marketing campaign.
What is Cost Per Acquisition (CPA)?
Cost Per Acquisition (CPA) measures how much, on average, a business spends in marketing or advertising to gain one new customer, lead, or sale. It is one of the most common efficiency metrics used to judge a marketing campaign.
How it’s calculated
CPA is simply your total campaign spend divided by the number of acquisitions that spend generated: CPA = Total Spend / Number of Acquisitions. A lower CPA generally means a more cost-efficient campaign, though it should always be weighed against the value of each acquisition.
This calculator is for general marketing planning and education; actual campaign performance depends on many additional factors such as attribution windows and audience quality.
