Return on ad spend
—
ROAS (return on ad spend) is the revenue you earn for every dollar spent on advertising, shown as a multiple like 4×. It's the fastest way to judge whether a paid campaign is pulling its weight. Enter revenue and spend below — and add your profit margin to see the break-even ROAS you need to clear.
How to calculate roas
Formula
ROAS = Revenue from ads ÷ Ad spend · Break-even ROAS = 1 ÷ Profit margin
Divide the revenue attributed to your ads by what you spent on them. A ROAS of 4× means $4 back for every $1 in. But profitable ROAS depends on your margins: if you keep 40% profit on each sale, your break-even ROAS is 1 ÷ 0.40 = 2.5×, so anything above 2.5× is making money. Enter a margin to see that threshold.
Example
Ads produced $12,000 in revenue from $3,000 in spend.
ROAS = 12,000 ÷ 3,000 = 4× (i.e. 400%).
