ACoS or Advertising Cost of Sales is the percentage of sales made through Sponsored Ad Campaigns. On Amazon Seller Central, this will be already provided for you in the advertisement. ACOS = Total Ad Spend/Total Ad Sales x 100. Example 1 (image below): Ad spend = $280.66 | Ad sales = $1,125.42.  $280.66/$1,125.42 = 0.24938
