ROAS – Return on Ad Spend

Definition

ROAS (Return on Ad Spend) measures the revenue generated per advertising euro spent. A ROAS of 5 means: for every €1 in ad spend, €5 in revenue is generated. ROAS is the most important profitability metric in performance marketing and the basis for budget allocation and scaling decisions.

Formel

Beispiel

A campaign generates €15,000 in revenue with €3,000 in ad spend. The ROAS is 15,000 / 3,000 = 5.0 (or 500%). This means: every euro invested returns €5 in revenue. Whether this is profitable depends on the margin – with a 30% margin, the break-even ROAS is 3.3.
