Return on Ad Spend (ROAS)

What is ROAS?


Return on Ad Spend (ROAS)
is a key metric that measures the effectiveness of advertising campaigns by comparing revenue generated to the cost of ads. Also called ad ROI or advertising efficiency, ROAS helps retailers understand how well marketing spend translates into sales.

Calculating ROAS for eCommerce
ROAS is calculated as:

ROAS=Revenue from AdsCost of Ads\text{ROAS} = \frac{\text{Revenue from Ads}}{\text{Cost of Ads}}ROAS=Cost of AdsRevenue from Ads​

For example, a ROAS of 5 means every $1 spent on advertising generates $5 in revenue.
