Cost Per Acquisition (CPA) is a marketing term used to describe the cost associated with acquiring a new customer or action. It is a standard metric used by marketers to measure and evaluate their marketing campaigns, often in comparison to other campaigns.
CPA is also known as Cost Per Lead, Cost Per Action, or Pay Per Acquisition. It is often used to measure the effectiveness of a marketing campaign and can be used to compare the success of different types of marketing campaigns.
In a nutshell, CPA measures the cost of acquiring a customer or action, such as a sale or a click on a product. CPA is a relatively simple way of evaluating ROI and helps a business to determine the value of the given campaign.
CPA is calculated using the following formula:
CPA = Total Cost of Campaign / Number of Actions Taken
For example, if a business spends $100 on a campaign and 10 people take action, the CPA is $10. This means that it cost the business $10 to acquire each action.
It’s important to note that this calculation is general across all types of campaigns. For example, if an email sends 1000 people to buy a product and 5 of them buy, the CPA would be $20.

CPA can be used to compare different types of campaigns or the same campaign over time. For example, if a business runs a campaign on social media and email, it can compare the cost, the number of leads generated, and the conversions from each and determine which one is working better.
Another way to use CPA is to measure the effectiveness of different channels. By calculating CPA for each channel, a business can determine which channels are generating more leads or conversions.
CPA can also be used to measure the effectiveness of different targeting strategies. A business can compare the cost to acquire a customer through different types of targeting (e.g. age, gender, location, etc.) to determine which type of targeting is working best.
When calculating CPA, there are a few important factors to consider. Firstly, the cost should include all costs associated with a given campaign, including any advertising costs and the cost of labour. Secondly, the number of actions should be accurately tracked. Finally, the campaigns should be compared on a like-for-like basis (i.e. comparing campaigns that use the same strategy with the same budget).
When evaluating the success of a given campaign, it is important to take into account other factors such as customer lifetime value and customer retention. The goal of a marketing campaign should not just be to acquire new customers, but also to ensure that these customers remain loyal over time.
