ROAS = Revenue from Ads ÷ Ad Spend
Break-Even ROAS = 1 ÷ Contribution Margin % — the minimum ROAS needed to cover product + shipping + packaging + gateway + RTO costs. Always use contribution margin, never gross margin.
Contribution Margin % = (Selling Price − All Variable Costs − RTO Loss) ÷ Selling Price
Profit per ₹1 Spent = (Revenue − Total Costs − Ad Spend) ÷ Ad Spend
Monthly Profit/Loss = Revenue from Ads − Total Costs (COGS + shipping + packaging + gateway + RTO) − Ad Spend
Example: Product at ₹599 with ₹150 COGS, ₹55 shipping, ₹25 packaging, ₹14.14 gateway (2.36%), and ₹29.91 RTO buffer (10%). Total variable cost = ₹274.05. CM = 54.2%. Break-even ROAS = 1 ÷ 0.542 = 1.84x. You need 1.84x ROAS just to break even after all costs. Anything above that is profit. For a typical product with 40% CM after RTO, break-even ROAS is 1 ÷ 0.40 = 2.5x — this is why 2.5x is the common Indian D2C benchmark.
