ROAS Calculator
ROAS (Return on Ad Spend) is the most quoted ad metric and the most misleading. A 3x ROAS sounds good until you realize that with 60% cost of goods, you're losing money. This ROAS Calculator shows your reported ROAS, your true ROAS after COGS, and the break-even ROAS your store needs to hit before ads make profit.

Frequently asked questions
Quick answers to the most common questions sellers ask.
Depends on margins. With 40% COGS, 2x ROAS is barely break-even; aim for 3x+. With 20% COGS, 1.5x can be profitable.
