ROAS calculator
Enter attributed revenue and advertising cost to calculate return on ad spend. Use the same currency for both values.
Enter revenue and a cost greater than zero.
ROAS = attributed revenue ÷ advertising costHow to use the result
ROAS measures attributed revenue, not profit.
A 4× ROAS means four units of attributed revenue for every one unit of advertising cost. Whether that is profitable depends on margin, fulfilment, fees, agency or staff cost and attribution quality.
