What is break-even ROAS?
Break-even ROAS is the point where your ad spend exactly equals the gross profit that spend produced. Below this threshold a campaign loses money; above it, the campaign starts earning.
The threshold depends entirely on your profit margin. A business with a thin margin has a high break-even point, a business with a wide margin a low one. This is why the same ROAS figure means completely different things to two different businesses.
How it is calculated
Break-Even ROAS = 1 ÷ Profit Margin
Enter your profit margin as a percentage. The tool converts it to a ratio and inverts it; the result is the ROAS at which gross profit exactly covers ad spend.
The margin here is gross margin: what remains of the sale price after cost of goods, divided by the sale price. If you fold fixed costs such as rent and salaries into that margin, you get a more conservative and therefore higher threshold.
How to read the result
The number you get is a floor, not a goal. Below it, every extra unit of spend deepens the loss; exactly on it, you neither gain nor lose.
As your margin narrows, the threshold climbs quickly. That means a price cut or a rise in product cost can push a campaign into loss even when its advertising performance has not changed at all.
Frequently asked questions
Should I enter gross or net margin?
Starting with gross margin is standard and reflects what is left per sale after cost of goods. Including fixed costs as well produces a more conservative, higher threshold.
Why is break-even ROAS not the same as target ROAS?
Break-even is the zero profit point. Target ROAS is the ratio needed to earn a specific net profit, and by definition it sits above the break-even threshold.
What if my margin differs by product?
Use the weighted average margin of the product set the campaign promotes. For a campaign focused on a single product, entering that product’s own margin gives a more accurate result.
