Advertising cost of sales (ACOS)

Advertising cost of sales (ACOS) is the percentage of direct sales you made from Sponsored Products ads, or the overall brand sales you made from Sponsored Brands that resulted from your advertising campaign. This is calculated by dividing total ad spend by total sales from advertising.

ACOS = total ad spend / total ad sales x 100

For example, if you spent $2 on advertising and those ads resulted in sales of $20, your ACOS would be 10%.

How to use ACOS

ACOS helps you measure the effectiveness of your campaigns relative to your advertising spend. A lower ACOS means your spending a lower percentage of sales on advertising. Learn more about sales

Note: For Sponsored Products campaigns, your sales data can take up to 48 hours to populate. For Sponsored Brands, brand sales data can take up to 12 hours to populate. As a result, ACOS is not available in the “Today” date range and might be delayed in the “Yesterday” date range.

ACOS recommendations by campaign targeting type

To minimize your spend on advertising, you’ll want to lower your ACOS. If your goal is to increase exposure of a new or existing ASIN, you might be okay with a higher ACOS for a set period of time.
