ACoS (Advertising Cost of Sales) = ad spend ÷ ad-attributed sales × 100. It tells you what percentage of revenue is going to ads. Lower ACoS means more efficient spending; ROAS (Return on Ad Spend) is the inverse and is expressed as a multiple (e.g. 4x).
Break-even ACoS is the maximum ACoS you can run without losing money. Formula: (net payout from marketplace − product cost) ÷ payout × 100. Below break-even ACoS = profit; above = loss. Our calculator computes this automatically using actual Amazon/Flipkart fee tables.
A profitable ACoS depends on your desired margin. Target ACoS = ((payout − cost) − desired profit) ÷ payout × 100. For most Indian sellers, a target ACoS that leaves 10–15% net margin is sustainable for scaling.
Different fee structures yield different per-order payouts. Amazon’s referral + closing + weight-handling + GST on a ₹1,500 apparel item nets ~₹969; Flipkart’s commission + fixed + shipping nets ~₹964. Same product, slightly different break-even ACoS.
Three levers: (1) tighter targeting and negative keywords; (2) higher conversion rate via listing optimisation; (3) better organic ranking that reduces ad reliance. ShopSurge runs all three for 20+ Indian brands — book a free audit to see your specific leakage.
