About This Calculator
ROAS (Return on Ad Spend) measures the revenue generated for every dollar spent on advertising. This calculator computes your ROAS ratio and percentage from your total ad spend and the revenue it generated.
How This Is Calculated
ROAS = Revenue Generated ÷ Ad Spend
$5,000 in ad spend generating $20,000 in revenue gives a 4:1 ROAS (or 400%).
Assumptions
- ROAS measures revenue, not profit — a high ROAS doesn't guarantee profitability if margins are thin.
- Does not account for other marketing costs beyond direct ad spend.
