What this measures
ROAS (Return on Ad Spend) measures how much revenue you earn for every dollar you spend on advertising. A ROAS of 4× means $4 of revenue for every $1 of ad spend.
ROAS is a revenue metric, not a profit metric — it doesn't account for product cost, fees or shipping. A campaign can have a strong ROAS and still be unprofitable, which is why pairing it with break-even ROAS and net profit matters.
The formula
ROAS = Revenue from ads ÷ Ad spend. As a percentage, multiply by 100.
Worked example
If a campaign generates $8,000 in revenue from $2,000 in ad spend, ROAS is 8,000 ÷ 2,000 = 4× (or 400%). You earned $4 of revenue for every $1 spent.
