Overview

In early February 2026 Amazon introduced a downloadable “SKU Economics” report that consolidates every fee, cost, and net revenue figure for a seller’s entire inventory into a single spreadsheet. The tool replaces the older method of stitching together separate sales, fee, and advertising extracts, delivering a one‑stop view of profitability for each SKU. Sellers with large catalogs—especially those managing thousands of items—should care because the new report removes manual data merging and surfaces previously hidden fees such as the low‑inventory penalty on a per‑product basis.

Key Points

• All‑in‑One Export — The CSV file now contains sales revenue, Amazon‑imposed fees, advertising spend, and off‑Amazon expenses for every SKU, eliminating the need to combine three distinct reports.
• Month‑by‑Month Fee Columns — Each fee type (referral, fulfillment, storage, etc.) appears with separate columns for every month in the selected period, allowing sellers to track, for example, a storage fee increase from $0.12 in Q1 2025 to $0.45 in Q2 2026 for a specific ASIN.
• Low‑Inventory Fee Visibility — The controversial penalty applied when a standard‑size item falls below its historic inventory threshold is listed alongside other charges, showing a $0.08 fee on a blue size‑M shirt that sold 150 units in March.
• Multi‑Level Aggregation — Data can be grouped by FNSKU, MSKU, ASIN, or parent‑ASIN, so a seller can compare the margin of a single color variant against the overall performance of the entire product line.
• No Additional Charge — The report is free for all third‑party sellers in Seller Central, removing the need to purchase external analytics tools for basic margin calculations.

How SKU Economics Report Works

1. Locate the Report Section — In Seller Central, navigate to the “SKU Economics” tab under the “Reports” menu; the download button sits beneath the on‑screen profitability widget. Example: A Professional‑plan seller clicks “Download CSV” to retrieve the file for the previous month.
2. Select Aggregation Level — Choose the desired grouping (FNSKU, MSKU, ASIN, or parent‑ASIN) from a drop‑down menu before generating the file.
