Step-by-Step Mathematical Derivation

ROAS Yield Calculation

ROAS = Attributed Revenue / Ad Spend. For example, $35,000 / $10,000 = 3.50×.

Breakeven ROAS Derivation

To not lose money, Gross Profit = Ad Spend. (Revenue × Margin%) = Ad Spend, implying Breakeven ROAS = Revenue / Ad Spend = 1 / Margin%.

Net Economic Ad Profit

Net Profit = (Attributed Revenue × Margin%) - Ad Spend.
