What the Product Analyzer Calculates

The Product Analyzer is built for the early product decision: before you order inventory, it helps you estimate whether a SKU can survive Amazon fees, inbound shipping, launch costs, and PPC. Enter the selling price, landed cost, dimensions, weight, expected conversion rate, and launch assumptions to see estimated net profit, margin, ROI, break-even ACOS, and payback pressure in one workflow.

Methodology

The calculator uses deterministic formulas rather than AI guesses. Net profit starts with selling price and subtracts referral fees, fulfillment fees, storage assumptions, cost of goods, inbound freight, advertising cost per unit, coupon cost, and launch expenses. Break-even ACOS is calculated from contribution margin before ads. ROI compares estimated profit against the cash tied up in inventory and launch spend.

The output should be treated as a planning estimate. Amazon fee schedules, size tiers, storage charges, and referral rates can change, so sellers should verify final numbers against Seller Central before buying inventory. For a plain-English walkthrough, read the Amazon profit calculation guide and the FBA fee reference.

Example Use Case

If a kitchen accessory sells for $29.99, costs $6.20 landed, and needs $3.00 of PPC per sale during launch, the analyzer shows whether the remaining margin can cover referral fees, FBA fees, returns, and storage. Sellers can duplicate the scenario, raise or lower price, change ad spend, and compare whether a larger order quantity actually improves profit or only increases cash risk.
