Facebook CPA stands for Cost per Action on Facebook Ads. It represents the average cost you incur for a user to complete a specific action – like signing up, purchasing, or submitting a form – through your Facebook ad campaigns.
To calculate Facebook CPA, divide the total ad spend by the number of desired actions taken as a result of your campaign.
If you spend $1,000 on a Facebook campaign and generate 200 signups, your Facebook CPA would be 1000 / 200 = $5 per signup.
