What is ROAS?
Short answer
ROAS (return on ad spend) is revenue from ads divided by the amount spent on them. A ROAS of 3 means ₹3 of revenue for every ₹1 spent.
ROAS is easy to calculate but depends on attribution, meaning which sales you credit to which ads. Different tools and attribution windows can give very different ROAS for the same campaign.
ROAS also ignores costs beyond ads, such as product cost and shipping, so a “good” ROAS depends on your margins.
For reach-focused channels, ROAS is only part of the picture. See how to measure short video campaign results.
