Common questions

Break-even ROAS is the revenue multiple you need for ad spend to exactly cover the cost of the goods or services you sell. It is 1 divided by your gross margin. At a 65% gross margin, break-even ROAS is 1 / 0.65, which is 154%. Anything below that loses money on every order before overhead.
