Record one product and marketplace. Product/ASIN: __________ Marketplace: __________ Period: __________ Selling price per order (net of discounts): __________ Referral and platform fees: __________ Fulfilment or shipping: __________ Landed product cost: __________ Returns and expected refund cost per order: __________ Other variable cost per order: __________ STEP 2. Calculate the pre advertising contribution. Contribution = price - all costs above. Break even ACoS (%) = contribution / attributable sale price * 100. If contribution is zero or negative, there is no profitable positive ACoS threshold. Target ACoS should reflect the profit you intend to retain, not simply the break even limit. STEP 3. Check advertising data on the same attribution basis. Ad spend: __________ Attributed ad sales: __________ Observed ACoS = ad spend / attributed ad sales * 100 when sales > 0. If attributed sales = 0, mark ACoS undefined rather than dividing by zero. STEP 4. Record decision and uncertainty. Conversion attribution window: __________ Known data gaps: __________ Decision: keep / monitor / investigate / adjust Reason and next review date: __________ Important: Account for taxes and returns using your own accounting model. ACoS alone is not total business profitability. Read: https://aainulraza.online/blog/amazon-ppc-break-even-acos-and-target-acos/
