Break-even ROAS = 1 ÷ profit margin. If your profit margin is 40%, you need a ROAS of 2.5× just to break even — every dollar below that loses money. Enter your margin to see your break-even and target ROAS.
What is Break-Even ROAS Calculator?
Break-even ROAS is the return on ad spend at which a campaign exactly covers its costs — the line between profit and loss. Knowing it turns 'is this campaign working?' into a precise, answerable question.
How it works
Break-even ROAS = 1 ÷ profit margin. If your margin is 40% (0.40), your break-even ROAS is 2.5 — you need $2.50 in revenue per $1 of ad spend just to break even. Anything above that is profit.
How to use this tool
Enter your profit margin (or price and cost). The calculator returns your break-even ROAS. Compare it to your actual ROAS to instantly see whether a campaign is truly profitable.
Why it matters
A '3x ROAS' campaign sounds great — but if your break-even is 3.5x, you're losing money on it. Break-even ROAS is the benchmark that makes every other ROAS number meaningful, and it's the target your campaigns must clear.
Frequently asked questions
What is break-even ROAS?
The return on ad spend where revenue exactly covers product and ad costs. Above it you profit; below it you lose money, no matter how high the raw ROAS looks.
How do I lower my break-even ROAS?
Increase your profit margin — raise prices, cut cost of goods, or lift average order value. A higher margin means you break even at a lower ROAS, giving campaigns more room to profit.
Why is my profitable-looking campaign losing money?
Because its ROAS is below break-even. Always compare actual ROAS to your break-even threshold, not to zero.
