return on ad spend calculator
about this tool
Return on ad spend (ROAS) is the paid media equivalent of ROI — it tells you how much revenue you’re generating for every pound or dollar spent on advertising. A ROAS of 4x means you’re making £4 for every £1 spent on ads. Whether that’s good depends on your margins and business model, but knowing your ROAS is the starting point for evaluating and optimising your paid campaigns.
This free ROAS calculator makes it simple: enter your ad revenue and ad spend, and the tool returns your ROAS as a clean multiplier. No formulas to remember, no spreadsheet needed.
It’s an essential everyday tool for PPC managers, e-commerce marketers, and performance marketing teams who run paid campaigns and need to report on their efficiency. Tracking ROAS campaign by campaign and channel by channel helps you put budget where it’s working hardest. Combine it with CPA and conversion rate data and you have a pretty complete picture of paid media performance.
