Quick answer
Break-even CPA is the most you can pay to win a customer without losing money on the sale. Multiply your average order value by your profit margin: a $200 order with a 30% margin gives a $60 break-even CPA. Paying more than that loses money on the first sale, unless customers buy again.
How it works
Average order or deal value and the gross margin you keep after product or delivery costs.
How often a customer buys per year and for how many years they stay.
Your lead-to-customer rate and the LTV to acquisition cost ratio you want.
