Why
Why ROAS matters
ROAS helps you judge whether ad spend is bringing back enough revenue to justify more budget.
See if spend is paying back
ROAS shows how much revenue came back for each dollar spent, which makes return easier to read at a glance.
Set safer budget limits
A clear ROAS target helps you decide how far you can scale before the return gets too thin.
Tie revenue back to margin
Revenue alone is not enough. Margin changes whether a strong-looking ROAS is actually safe for the business.

ROAS means return on ad spend. It shows how much revenue came back for each dollar spent on ads.
Use the formula ROAS = revenue / ad spend. A ROAS of 4 means every $1 in ad spend brought back $4 in revenue.
There is no one perfect ROAS. A good ROAS depends on your margin, business model, and growth goals. Margin decides how much of that revenue you really keep.
ROAS shows revenue compared with spend. ACOS shows spend compared with revenue. They are two views of the same math.
Margin changes the break-even point. A ROAS can look good on the surface but still be weak if the margin is thin.
