ROAS in the Black
A free tool built for marketers, ecommerce brands, and business owners who want to know their exact break-even ROAS before spending another dollar on ads.
No sign-up. No upsell. Just the math.
Most advertising tools want you to connect your ad accounts, pay a monthly fee, or sit through a demo before you can get to the one number that actually matters. We thought that was backwards.
ROAS in the Black does one thing: it takes your cost structure and tells you the minimum Return on Ad Spend you need to cover your costs. Enter your COGS, fulfillment, and other variable costs, and you get your break-even ROAS instantly. No account required.
What is break-even ROAS?
Break-even ROAS is the exact ROAS at which your ad-driven revenue covers all your variable costs — cost of goods, fulfillment, platform fees, returns, and anything else that scales with each sale. Below this number, every order you drive through paid ads loses money. Above it, you're generating real profit.
The formula is: Break-Even ROAS = 1 ÷ Gross Margin. If your total variable costs are 60% of revenue, your gross margin is 40%, and your break-even ROAS is 2.5x. Any campaign running below that is spending money to lose money — no matter what the dashboard says.
Why it matters before you scale
Scaling ad spend without knowing your break-even ROAS is one of the most common — and costly — mistakes in performance marketing. Campaigns that look profitable on the platform report are often running below break-even once you account for the full cost structure. The more you spend, the more you lose.
Knowing your number changes how you bid, how you evaluate creative performance, and how you set target ROAS goals in Google Ads or Meta Ads Manager. It turns "is this campaign good?" from a gut call into a math problem with a definitive answer.
