Enter your ad spend and revenue to calculate ROAS instantly. Reverse-calculate the required revenue from a target ROAS, or find the allowable ad budget from a target revenue. Add a gross margin percentage to see your break-even ROAS. Everything runs in your browser with no data sent to a server.
ROAS (%) = ad revenue ÷ ad spend × 100ROAS (Return on Ad Spend) is revenue relative to ad spend, calculated as revenue ÷ ad spend. A ROAS of 400% (or 4:1) means every 1 spent on ads produced 4 in revenue. Comparing ROAS across channels, campaigns, and creatives shows where to add budget and where to cut, which is why it's the first number performance marketers look at.
This calculator turns ad spend and revenue into ROAS instantly, and also reverse-calculates the target revenue or allowable ad spend you'd need.
A high ROAS isn't automatically profitable, because you have to account for product margin. At a 25% margin, the break-even ROAS that just recovers ad cost is 400%, and you only profit above that. So the same ROAS of 300% can be profitable on a high-margin product and a loss on a low-margin one.
That means your target ROAS should be built on your margin structure. Setting a target and reverse-calculating allowable spend and required revenue lets you plan budgets by the numbers rather than by feel. Everything runs in your browser.
What it is, who it's for, how it works and why you'd use it.
ROAS Calculator is a tool that computes Return on Ad Spend (ad revenue ÷ ad spend × 100), reverse-calculates target revenue or allowable ad budget from a target ROAS, and derives break-even ROAS from a gross margin percentage.
It is for marketers tracking ad performance, small business owners running digital ads, and PMs planning campaign budgets.
In ROAS mode, enter ad spend and revenue to get ROAS (%) and ROAS multiple instantly. In target modes, enter the target value to reverse-calculate the missing number. Enter a gross margin percentage to see the break-even ROAS.
ROAS is the most direct measure of advertising efficiency. Setting a target ROAS and reverse-calculating required inputs lets you plan budgets with precision rather than guesswork.
