CPA is what you paid for each acquisition, whatever counts as one for the campaign: a sale, a sign-up, an install. 2,000 spent for 80 sales is 25 each.
CPA = spend ÷ acquisitions
Enter what one acquisition is worth and the tool shows the profit each one leaves after CPA, and the return on cost. A negative profit means each acquisition costs more than it brings in.
