Frequently Asked Questions

RoAS here is revenue divided by ad spend ONLY — it doesn't account for product cost. ROI Calculator Ecommerce divides profit by ad spend PLUS COGS combined, giving a fuller picture of true profitability. A high RoAS doesn't guarantee a profitable campaign once COGS is factored in.

This tool bands it as strong at 4x or higher, moderate at 2-4x, and likely unprofitable below 2x — but the real answer depends on your margin. The tool also shows the rule 'Target RoAS = 1 ÷ Gross Margin %', e.g. a 40% margin needs at least 2.5x RoAS just to break even.

No — it's a simplified breakeven rule based only on gross margin, not COGS, returns, or overhead. Use it as a floor, not a target, and confirm true profitability with ROI Calculator Ecommerce or Ecommerce Profit Calculator.

Revenue you attribute specifically to the ad campaign being measured — not your store's total revenue across all channels.
