Return-on-ad-spend formulas
ROAS = attributed revenue ÷ advertising cost. Reverse modes multiply or divide the same ratio to solve revenue or cost.
Worked example
$20,000 attributed revenue divided by $5,000 ad cost gives 4× ROAS.
Revenue is not profit
ROAS compares attributed revenue with ad spend only. It does not include product cost, overhead, taxes, attribution uncertainty, incrementality, or lifetime value, and it is not ROI.
