About the ROAS Calculator
Return on ad spend divides attributed revenue by advertising cost. Revenue of 5,000 on a spend of 1,000 is a 5x ROAS, or 500%. ROAS is a gross revenue measure, not profit: a campaign can show a strong ROAS and still lose money once product costs, fees and overheads are counted. Results also depend on the attribution window and model your ad platform uses, so compare like with like. The target mode inverts the formula: the most you can spend for a 4x target on 5,000 of revenue is 1,250.
