ROAS Calculator

Divide revenue by ad spend to get return on ad spend, and compare it against your break-even.

About ROAS Calculator

The ratio divides one figure by the other and is read against a conventional benchmark of 4. Both the ratio and its percentage form are shown, because different audiences expect different presentations of the same number. A advertising return compresses two absolute figures into one comparable number, which is what makes it usable across companies and periods of different size.

Formula

ROAS

Return on Ad Spend = Revenue attributed to ads ÷ Ad spend

Revenue attributed to ads: Numerator of the ratio
