ROAS Calculator
Calculate return on ad spend and compare it with margin-based break-even ROAS.
Check whether ad spend is earning enough
ROAS is a fast way to compare paid campaigns, but it can be misleading when margin is ignored. A 3x ROAS may be excellent for a high-margin product and weak for a low-margin one.
The number that matters is break-even ROAS, which is one divided by your margin: at a 50% margin you need a 2x return just to cover costs, so a '3x ROAS' is only modestly profitable.
Enter spend, revenue, and gross margin. The calculator returns ROAS, gross profit after margin, net contribution after ad spend, and break-even ROAS.
