Calculate ROAS (return on ad spend) from revenue and ad spend.

The ROAS Calculator works out your return on ad spend (ROAS) from the revenue a campaign generated and the amount you spent on ads. It shows ROAS as a ratio, as a percentage and as profit, so you can tell at a glance how many dollars of revenue each dollar of spend returned.
ROAS (return on ad spend) is revenue divided by ad spend. A ROAS of 4× means you earned $4 in revenue for every $1 spent on ads.
ROAS compares revenue to ad spend only, while ROI compares profit to the total cost. ROI accounts for margins and other costs, so it is usually lower than ROAS.
