ROAS Calculator formula

The ROAS Calculator uses your campaign revenue and ad spend to calculate return on ad spend.

ROAS = Campaign Revenue ÷ Ad Spend

How to use this ROAS Calculator

Enter your ad spend and the revenue generated by the campaign. The ROAS Calculator shows your return as a multiple, percentage, cost per conversion and average order value. If you add gross margin, it also estimates break-even ROAS and profit after ad spend.

A high ROAS does not always mean profit. A 3x ROAS can be excellent for a high-margin product and weak for a low-margin product. The most useful number is your break-even ROAS, because it shows the minimum ROAS needed before advertising becomes profitable.
