At that CPA you make zero profit on the order; a break-even ROAS of 2.67 is the equivalent ceiling for ad spend.\n\nHow it breaks down per $70 order:\n- Gross profit: $70 − $35 landed = $35 (50% gross margin, 100% markup)\n- Minus shipping $5, payment fee $2.40 (3% + $0.30), refund reserve $1.40 (2%)\n- Contribution before ads: $26.20\n\nThis is a ceiling, not a target. It excludes fixed overhead, income tax, returns above your 2% reserve, and any ad-platform fees. As a practical rule, aim for a CPA well under $26.20 (e.g. leave room for 30–50% of contribution as actual profit) and confirm real CPA from verified spend and attributed orders before scaling anything. If your landed cost is a scenario rather than a confirmed supplier quote, re-run this once you have the quoted figure.",
