FAQ
CPA (cost per acquisition) = ad spend ÷ number of conversions. If you spent $600 for 24 conversions, your CPA is $25.
The math is identical — cost ÷ conversions. CPA usually refers to a sale or acquisition, while CPL refers to a lead (form fill, signup). This tool covers both.
Your CPA must stay below your payout (for CPA offers) or below customer lifetime value. Add your clicks to also see CPC and conversion rate, which are the two levers that move CPA.
