ROAS Calculator
Compare attributed advertising revenue with the spend that generated it.
Formula and assumptions
ROAS · ROAS ratio = Attributed ad revenue ÷ Advertising spend. ROAS percentage = Attributed ad revenue ÷ Advertising spend × 100. Revenue per currency unit spent = Attributed ad revenue ÷ Advertising spend.
Use matching attribution windows. Revenue does not account for fulfilment, refunds or margin.

How to use this tool
Choose the relevant mode, enter Attributed ad revenue and complete the labelled fields. Use Calculate to review your result.
Worked example
Attributed ad revenue = 800, Advertising spend = 200.
ROAS ratio = 4.00× · ROAS percentage = 400.00% · Revenue per currency unit spent = 4.00 currency units.
These example values are illustrative.
Interpreting the result
Compare the result with your break-even ROAS. A fourfold revenue return can support very different acquisition budgets for a digital download and a low-margin physical product.
Assumptions and limitations
Use matching attribution windows. Revenue does not account for fulfilment, refunds or margin.
Does a 4× return mean four units of profit?
It means four units of attributed revenue per unit of advertising spend. Subtract delivery costs to evaluate profit.
