ROAS formula
ROAS = revenue attributed to advertising ÷ advertising spend. A 4× ROAS means $4 in revenue for every $1 spent on ads.
ROAS is not profit
Use the optional gross-margin field to estimate how much of that revenue remains after direct product or service costs.
Example: $1,000 spend and $4,000 revenue
A campaign that attributes $4,000 in revenue to $1,000 in ad spend has a 4× ROAS. That means $4 of revenue for every $1 of advertising spend—not $4 of profit.
Why margin matters
A high ROAS can still be unprofitable when product cost, discounts, fulfillment, labor and campaign costs are high. Use the optional gross-margin and extra-cost inputs to get a more useful business view.
