ROAS & ROI Calculator
Compare advertising revenue with media spend and return on investment. No account needed.
Calculate revenue returns
ROAS = attributed revenue ÷ ad spend. ROI here is calculated from revenue less ad spend only; it does not include fulfilment or other costs.
What is ROAS versus ROI?
Return on ad spend describes attributed revenue per unit spent on media. Revenue of 1,800 against advertising spend of 500 produces 3.6× ROAS. The corresponding revenue-less-ad-spend return is 260%, but it is not full business ROI because it excludes product costs, labour, fees and other expenses.
Attribution models and conversion windows change reported revenue. Work with an agreed measurement method and use contribution margin when making profit decisions.
Frequently asked questions
Is 1× ROAS break-even?
Only if there are zero other costs. Real break-even ROAS usually needs to be higher.
Can revenue be zero?
Yes. Enter zero revenue to see a 0× ROAS and negative ad-spend-only return.
