Amazon's official tool (Seller Central) for estimating per-unit net profit on a specific product before committing to a launch.
Inputs: product category, target selling price, packaging dimensions/weight (in inches), fulfillment method (FBA or FBM), and cost of goods (landed cost per unit).
Matching approach: you can search for an identical-looking listing already on Amazon and let the calculator pull its category/dimensions, but this is less accurate than entering your own supplier's packaging data directly — the manufacturer or box size can differ even when the product photos look the same.
FBA vs FBM toggle: switching the fulfillment method recalculates fulfillment fees and net profit while referral fees stay constant, producing a comparison graph — see FBA vs. FBM (Fulfillment Model Split) for the fulfillment-model split; the calculator is the working tool used to compare them per-SKU.
Q4 worst-case storage setting: the tool lets you choose which time-of-year storage rate to apply. Selecting Q4 (holiday season) rates instead of the cheaper January–February rates deliberately front-loads the highest storage cost into the estimate, functioning as a built-in margin of safety before finalizing a net margin.
Precision expectation: inputs like FBM box cost (Uline Box-Cost Lookup) and shipping cost (LDR Prep.com Shipping Estimator) only need to be ballpark figures — the workflow is meant for fast go/no-go screening, not final accounting.
Output feeds directly into the Rule of Thirds (33% Net Margin) Amazon Profitability Heuristic check and the Reverse-Engineered COGS Ceiling negotiating technique.
