Return on Ad Spend (ROAS)
Return on Ad Spend (ROAS) measures how much revenue you make for each dollar spent on advertising. It's calculated by dividing your ad-generated sales by the cost of those ads. It helps businesses see if their ads are working effectively.
Return on Ad Spend = Gross Sales/Marketing Spend
Return on Ad Spend (ROAS), in the context of e-commerce, is a marketing metric that measures the gross revenue generated for every dollar spent on advertising. It is calculated by dividing the revenue generated from ads by the ad spend cost. Most e-commerce businesses use this metric as it provides insights into the effectiveness of their advertising campaigns.
However, ROAS has limitations when used in isolation. For instance, it does not consider the profitability of the products sold. A high ROAS does not necessarily translate to high profits if the products sold have a low-profit margin. Moreover, ROAS does not account for other shipping costs, such as fulfillment and returns. Therefore, focusing solely on ROAS without considering net profit can overestimate the actual return from advertising spend. Businesses must balance maintaining a strong ROAS with managing their overall profitability.

Wasted ad spend is budget that produced no incremental profit — spend on demand you would have captured anyway, on products that cannot convert, or on customers worth less than they cost to acquire.
Customer Acquisition Cost (CAC)
Customer Acquisition Cost (CAC) is the total cost of acquiring one new customer: acquisition spend divided by the number of genuinely new customers. It is distinct from cost per order, which includes returning customers and therefore flatters performance.
