Break-Even ROAS Calculator
Calculate the minimum ROAS needed to break even on ad spend. Based on your gross margin. Free browser-based calculator.
How Break-Even ROAS Calculator Works
Break-Even ROAS = 1 ÷ Gross Margin %. At 40% gross margin, you need 2.5x ROAS just to cover product costs before any profit. This calculator reveals the absolute minimum ROAS your campaigns must achieve. Once you know this floor, your target ROAS should be 2–3x higher to account for operating expenses and profit margin.

Frequently Asked Questions
What is break-even ROAS?
Break-even ROAS is the minimum return on ad spend required to cover your cost of goods. Formula: 1 ÷ Gross Margin. At 50% gross margin, break-even ROAS is 2x — every sale must generate at least 2x the ad spend to avoid a loss.
How is this different from target ROAS?
Break-even ROAS is your floor — the point of zero profit. Target ROAS is what you aim for to generate actual margin after covering all costs. Target ROAS should always be well above break-even, typically 1.5–2x above it.
Why does gross margin affect break-even ROAS?
Higher gross margin means more revenue is left after COGS, so a lower ROAS still covers costs. At 80% gross margin (typical SaaS), break-even ROAS is only 1.25x. At 20% margin (typical retail), it's 5x.
