What is ACoS and how is it calculated?

ACoS measures how much of your attributed sales is spent on advertising, expressed as a percentage. It is calculated as (Ad Spend / Attributed Sales) × 100. For example, if you spend $120 on ads and generate $2,000 in attributed sales, ACoS = (120 / 2000) × 100 = 6%. This tells you how much of every dollar in sales goes to ad costs. A lower ACoS means more efficient ad spend relative to sales, though the target depends on your margins and profitability. This is different from Return on Ad Spend (ROAS), which is Attributed Sales / Ad Spend. It’s also different from Cost per Click (CPC = Ad Spend / Clicks) and from simply Revenue minus advertising spend, which isn’t a standardized efficiency metric.
