Frequently asked questions
ROI vs ROAS — what is the difference?
ROI = (revenue − cost) ÷ cost, the true profit percentage. ROAS = revenue ÷ cost, which ignores cost and can look misleadingly high.
What is a good ROI?
It depends on risk and horizon. A positive ROI means you made money; compare against your alternatives and required return.
