Amazon Data Kiosk now shows three vendor metrics—shippedCogs, contraCogs, and contraCogsPerUnit—to make unit economics on shipped units clear.
Use netUnitCost = (shippedCogs + contraCogs) / shippedUnits; build SKU-level price floors with fees, ad cost per unit, plus target margin; alert when contraCogsPerUnit rises vs an 8–12 week trailing average.
Outcomes: cleaner pricing, quicker detection of return and allowance issues, and smarter replenishment.
