What came back from your ad spend?
Calculate return on ad spend using attributed revenue and advertising cost. Use the same currency, campaign scope and reporting period for both inputs.
Attributed revenue ÷ advertising spend
For example, attributed revenue of 5,000 and advertising spend of 1,000 give a result of 5 ×.
Keep the scope and reporting period consistent. Zero in the first field is valid; a zero denominator has no defined rate, so the calculator asks for a total greater than zero.
Make the number useful.
A result of 5× means five units of attributed revenue for each unit spent on advertising. Expressed as a percentage, that is 500%. The calculator does not need a currency selection because both inputs must already use the same currency.
ROAS is not profit or overall return on investment. Product costs, fulfilment, fees, refunds, tax treatment and other operating costs can change the economics. A ratio above 1× does not establish that a campaign is profitable.
The answer depends on which revenue you attribute to the campaign and over what window. Use a consistent attribution rule and distinguish observed activity from modelled platform reporting. UTM links can label arriving traffic, but they do not by themselves prove which advertising caused a sale.
