Margin (Seller)

Dashboard link: https://app.emax-digital.com/performance-summary-hub-seller/margin

Overview

The Margin dashboard shows your Company Margin — your true per-unit profitability on Amazon — for your Seller Central business. It combines the Average Net Received Price (what Amazon actually pays out to you per unit after fees) with the fixed and variable costs per ASIN that you maintain in your Seller Central Catalog, and turns the two into a clean margin percentage you can track over time, by marketplace, category, or product.

It is designed for Seller Central managers and finance leads who want to answer: "After Amazon's fees and my own product and fulfilment costs, what am I actually earning per unit — and is that margin improving or eroding?"

Important prerequisite: this dashboard only works if you have entered Fixed Cost per Unit and Variable Cost per Unit for your ASINs in the Seller Central Catalog inside the emax digital platform. ASINs without cost data are excluded from margin calculations, so the dashboard also tells you how complete your cost coverage is.

What You Can See on This Dashboard

Section: Catalog Cost Coverage

Two scorecards at the top of the dashboard show how much of your catalogue is actually feeding the margin calculation.

Key metrics:

• Number of ASINs in Catalog — total count of unique ASIN–marketplace combinations currently tracked in your catalogue, after applying the active filters. The same ASIN listed on multiple marketplaces is counted once per marketplace.

• ASINs with Cost Data — count of unique ASIN–marketplace combinations that have both Fixed Cost and Variable Cost defined with values greater than zero. Only these ASINs are included in the margin calculations on the rest of the dashboard.

The gap between these two numbers is your cost-data coverage gap — the ASINs whose margin you cannot currently measure.

Section: Margin Development — Trend Chart

A line chart of your Company Margin and Average Net Received Price over the most recent lookback window (12 weeks, 12 months, or 12 quarters, depending on the Reporting Range filter).

Key metrics:

• Company Margin (%) — (Avg. Net Received Price − Fixed Cost per Unit − Variable Cost per Unit) ÷ Avg. Net Received Price × 100. Plotted as a line.

• Avg. Net Received Price — total ordered product sales ÷ total sold units in the period. Reflects average revenue per unit after Amazon fees. Plotted as a line on a secondary axis.

Visualizations: Dual-axis line chart with Company Margin (%) and Avg. Net Received Price (currency) over time.

Section: Margin Trend Table

A period-by-period table that mirrors the trend chart with exact figures.

Columns shown: Report Date · Reporting Range · Date · Avg Net Received Price · Company Margin (%).

Use this table when you need the precise numbers behind the chart, or to copy a period series into a report.

Section: Methodology Note — Company Margin Definition

An in-dashboard explainer panel restating the Company Margin formula and the cost-data prerequisite. The key points:

• Company Margin = (Avg. Net Received Price − Fixed Cost per Unit − Variable Cost per Unit) ÷ Avg. Net Received Price

• Avg. Net Received Price = Total Product Sales ÷ Sold Units

• Fixed Cost per Unit and Variable Cost per Unit must be maintained in your Seller Central Catalog.

• If no cost data is entered for an ASIN, that ASIN is excluded from the calculation — it does not silently default to 100% margin in the aggregated figures.

Available Filters

Filter interaction notes

• Subcategory depends on Category. The Subcategory dropdown only shows values belonging to the selected Category.

• Reporting Range and Period work together. Switching Reporting Range (e.g. Monthly → Weekly) reloads the available Period values.

• All filters apply to both the catalog-coverage scorecards and the margin trend chart / table — so narrowing to a Category will also narrow the "ASINs with Cost Data" count to that segment.

Use Cases

1. Audit your cost-data coverage — Open the dashboard with all filters cleared. Compare Number of ASINs in Catalog against ASINs with Cost Data. If the gap is large, the margin figures only reflect part of your business — prioritise filling in Fixed and Variable Cost for the missing ASINs in your Seller Central Catalog before relying on the trend.

2. Track margin erosion over time — Set Reporting Range to Monthly and review the Margin Development chart for the last 12 months. A declining Company Margin alongside a stable Avg. Net Received Price points to rising costs; a declining Avg. Net Received Price points to fee creep or price drops. The two-line view tells you which side is moving.

3. Compare margin by marketplace — Run the dashboard once per marketplace (DE, UK, FR, IT, ES, etc.) and note the Company Margin for the same period. Marketplaces with structurally lower margin may need price repositioning or a review of FBA fees and returns.

4. Category-level profitability review — Filter to one Category at a time and check the Company Margin trend. Use this to identify low-margin categories that are dragging down the overall business, and high-margin categories worth scaling.

5. Validate the impact of a price change — After raising or lowering price on a key ASIN, filter to that ASIN and a weekly Reporting Range. Watch Avg. Net Received Price and Company Margin move together in the weeks following the change to confirm the net impact after Amazon fees.

Limitations & Notes

• Seller Central only. This dashboard covers Seller Central (3P) data. Vendor Central (1P) margin is tracked in the Vendor margin / Net PPM dashboards.

• Cost data is a prerequisite. ASINs without both Fixed Cost and Variable Cost defined (with values greater than zero) are excluded from all margin figures. The dashboard does not assume a default cost, and does not show 100% margin for unmaintained ASINs in the aggregated results — they simply do not contribute.

• Avg. Net Received Price reflects Amazon fees, not your own costs. It is the payout per unit from Amazon. The Company Margin formula then subtracts your fixed and variable costs on top.

• Cost data is your responsibility to keep current. If your supplier costs, packaging costs, or fulfilment costs change, you must update them in the Seller Central Catalog. The dashboard cannot detect stale cost figures.

• Fixed vs. Variable cost interpretation. "Fixed Cost per Unit" and "Variable Cost per Unit" are both per-unit values as entered in the Catalog. The dashboard does not split out cost components further — for a richer cost breakdown, refer to your Catalog settings.

• Marketplace-specific costs. Costs are stored per ASIN–marketplace combination, so the same product can carry different Fixed/Variable costs across marketplaces. Make sure costs are entered for each marketplace you sell on.

• Lookback window on the trend chart. The Margin Development chart shows the last 12 periods at the selected granularity. For a longer history, use the margin trend table and adjust the Period filter.
