How to calculate roas

Attributed revenue ÷ ad spend

ROAS measures revenue, not profit. Attribution, product costs and overheads can change whether a campaign is profitable.

A worked example

With ad spend of 1,000, attributed revenue of 4,000, return on ad spend is 4×. Change the example above to match your situation.

Enter amounts in the same currency and time period. Results display up to two decimal places; calculations use unrounded values. These estimates are for planning and education.

Common questions

What does a ROAS of 4 mean?

It means four units of attributed revenue for every one unit spent on advertising. For example, 1,000 of ad spend and 4,000 of attributed revenue give 4× ROAS.

Does a high ROAS mean a campaign is profitable?

ROAS compares revenue with advertising spend. It does not subtract product costs, fulfilment, overheads or tax, so profitability also depends on those costs and how revenue is attributed.
