FAQ
What is a good ROAS?
Any ROAS above your break-even ROAS is profitable on the first order. Break-even ROAS depends entirely on your margin: a 25% contribution margin needs 4× ROAS just to break even.
ROAS vs CPA?
ROAS is revenue ÷ ad spend. CPA is ad spend per order. At break-even, CPA equals your contribution margin per order.
