Cost Per Acquisition Calculator

Calculating Cost Per Acquisition (CPA) is essential for businesses to assess the efficiency of their marketing campaigns. CPA represents the cost incurred for acquiring a new customer or lead through marketing efforts. By knowing your CPA, you can make informed decisions on how to allocate your marketing budget effectively. To simplify this process, we’ve created a handy Cost Per Acquisition Calculator.


The formula for calculating CPA is straightforward:

CPA = Total Cost / Number of Acquisitions


  • Total Cost is the overall expenditure on a specific marketing campaign.
  • Number of Acquisitions is the total number of customers or leads obtained from that campaign.

How to Use

  1. Enter the total cost of your marketing campaign in the “Cost” field.
  2. Enter the number of acquisitions (customers or leads) in the “Acquisition” field.
  3. Click the “Calculate” button.
  4. The calculator will display your Cost Per Acquisition (CPA) in the “Result” field.


Let’s say you spent $1,000 on a Google Ads campaign, and from that campaign, you acquired 50 new customers. To calculate your CPA:

  • Cost = $1,000
  • Acquisition = 50

CPA = $1,000 / 50 = $20

So, your Cost Per Acquisition is $20.
