BBreak Even ROAS Calculator by DNA
Free break even ROAS calculator.
Peplio's take
This calculator tackles one of the most common and costly mistakes in e-commerce advertising. A campaign showing a “good” 2x ROAS on the dashboard can still be losing money on every order once product cost, shipping and fees are counted. This tool exposes that gap in seconds.
What makes it stand out is the context around the numbers. The max allowable CAC and target ROAS are far more useful for daily ad decisions than a single break-even figure, and the written explanation of why platform ROAS misleads you is genuinely educational. It’s the kind of tool every store owner running Meta or TikTok ads should check before scaling spend.
The trade-off is that results are only as accurate as the numbers you enter, and it’s built for product-based stores rather than service businesses. The page also promotes the company’s paid AI services, which is fair for a free tool. Best for e-commerce store owners, media buyers, performance marketers and agencies managing ad budgets.

What is Break Even ROAS Calculator by DNA?
Ad platforms often show a Return on Ad Spend (ROAS) that doesn't reflect your actual profitability. This free calculator helps you cut through the vanity metrics by calculating your true break-even ROAS. It uses your specific business costs, like product cost, shipping, and payment fees, to determine the exact ROAS at which your ad campaigns stop losing money.
Understanding your break-even ROAS is crucial for making informed decisions about your advertising budget. The tool also calculates your maximum allowable Customer Acquisition Cost (CAC), giving you a clear ceiling for ad spend per order. This ensures you're not overspending on ads and are making profitable sales, even when ad platforms report seemingly good ROAS figures.
Best forE-commerce businesses that run paid advertising campaigns and want to understand their true ad profitability.
