What Is Cost Per Acquisition (CPA)?

Cost Per Acquisition (CPA) is a marketing metric that measures the total cost of acquiring a paying customer within a specific campaign. As one of the most important performance indicators in digital advertising, CPA directly reflects how efficiently a business drives sales and achieves its marketing goals.

For example, if an advertiser spends $2,000 on an online advertising campaign in a month and generates 100 conversions (such as purchases on the company’s website), the Cost Per Acquisition (CPA) would be calculated as follows:

CPA = $2,000 / 100 = $20

This implies that each conversion in the campaign cost the company $20. In other words, it costs the business $20 to acquire a new customer.

Why Is CPA Important?

CPA measures the total cost of acquiring a customer through a specific ad campaign, offering marketers valuable insights into campaign efficiency. By understanding CPA, marketers can assess the effectiveness of their advertising efforts across paid channels. This allows them to make data-driven decisions, optimize strategies, and improve marketing performance for better results

What Is a Typical CPA Rate?

The typical Cost Per Acquisition (CPA) can vary based on several factors, including the industry, market conditions, advertising platform, conversion rate, and the overall effectiveness of the marketing campaign.

While there's no one-size-fits-all answer, here are some general guidelines:

  • B2B industries often have higher CPAs ($100-$300+) due to longer sales cycles and higher customer values
  • E-commerce CPAs typically range from $10-$50 depending on product price points
  • Lead generation campaigns might have CPAs between $30-$100
  • Mobile app installs can have CPAs from $1-$10

Remember that a "good" CPA is one that allows your business to be profitable, considering the lifetime value of your customers.
