Return on Ad Spend (ROAS) is a marketing metric that measures the revenue earned for every dollar spent on advertising. A ROAS of 4:1 means you earn $4 for every $1 spent. Break-even ROAS tells you the minimum ROAS needed to cover your costs based on your profit margin. This calculator helps you evaluate your advertising campaign performance and make data-driven decisions. All calculations happen entirely in your browser — no data is ever sent to a server.
ROAS (Return on Ad Spend) is a marketing metric that measures how much revenue you generate for every dollar spent on advertising. It is calculated as: Revenue / Ad Spend. A ROAS of 4:1 means you earn $4 for every $1 spent on ads.
A good ROAS varies by industry. E-commerce typically sees 3:1 to 4:1, SaaS companies often achieve 5:1 to 10:1, local services average 2:1 to 3:1, and B2B companies usually target 3:1 to 5:1. The best benchmark is your own break-even ROAS based on your profit margin.
Break-even ROAS is the minimum ROAS you need to achieve to cover your costs. It is calculated as: 1 / Profit Margin. For example, if your profit margin is 25%, your break-even ROAS is 4:1 (1 / 0.25 = 4).
Common strategies include improving ad targeting, optimizing landing pages, A/B testing creatives, refining keywords, increasing customer lifetime value, and reducing cost per acquisition.
