Break-Even ROAS Calculator

Break-even ROAS is the minimum return on ad spend needed to cover all your product costs. At exactly your break-even ROAS, you're not making or losing money on each sale — ad revenue covers the cost of goods, shipping, and the ad spend itself.

This metric is critical for setting campaign targets. Many advertisers chase the highest possible ROAS, but that often means under-investing in ads. Knowing your break-even point lets you scale spending confidently: any ROAS above break-even is profit, and you can make informed decisions about how aggressively to bid.

Break-even ROAS is directly tied to your gross margin. Higher margins mean a lower break-even point, giving you more room to absorb higher ad costs. Lower margins mean you need stronger campaign performance to stay profitable.

The formula starts with your gross margin:

Gross Margin = (AOV - COGS - Other Costs) / AOV

Break-Even ROAS = 1 / Gross Margin

For example, if your average order value is $100, COGS is $40, and other costs (shipping, payment processing, returns) total $10, your gross margin is ($100 - $40 - $10) / $100 = 50%. Your break-even ROAS is 1 / 0.50 = 2.0x.

This means every campaign needs to return at least $2 in revenue for every $1 in ad spend just to cover costs. If your actual ROAS is 3.0x on a $1,000 campaign, you're generating $3,000 in revenue, with $1,500 covering product costs, $1,000 covering ad spend, and $500 in profit.

Your gross margin determines how much flexibility you have with ad spending. Here's how break-even ROAS changes across different margin ranges:

Gross Margin	Break-Even ROAS	Typical For
70%+	1.4x or less	Digital products, SaaS
50–70%	1.4x – 2.0x	DTC brands, premium ecommerce
30–50%	2.0x – 3.3x	General ecommerce, retail
Below 30%	3.3x+	Low-margin goods, commodities

If your break-even ROAS is above 3.0x, consider improving unit economics before scaling ad spend. Negotiate better supplier pricing, reduce shipping costs, or increase average order value through bundles and upsells.
