Understanding Your Result
Break-even ROAS = 1 ÷ Gross Margin. At 40% gross margin, break-even ROAS is 2.5× — any ROAS below this loses money on ad spend. Target ROAS for profitability should factor in LTV: if average customer makes 3 purchases, target ROAS based on 3× first-purchase margin. Google benchmark by industry: Retail 4–7×, E-commerce 3–5×, Lead gen 8–12× (cost per lead basis). ROAS below 1× means you spend more on ads than you make in revenue — an immediate loss situation.
