About this calculator

This calculator divides revenue generated by an ad campaign by the amount spent on it, expressing the result as a ratio like 4:1 or "$4 for every $1 spent" — the standard ROAS (Return on Ad Spend) formula used across digital advertising. Unlike ROI, ROAS looks only at gross revenue against ad cost, without subtracting product cost, shipping or other overhead.

Performance marketers reporting campaign results, e-commerce sellers deciding whether to scale a Facebook or Google Ads campaign, and agencies benchmarking one client's account against another all use ROAS as the first health check on ad spend, typically looking for at least 3:1–4:1 to stay profitable after other costs are factored in.
