Margin spread

The margin spread is the small box-and-whisker chart next to a product's margin. A single product often bundles several models or listings — different sizes, bundles, or the same item across shops — and each can earn a very different margin. The headline number is just the middle of that range; the whisker shows the whole shape, so a comfortable average can't quietly hide a variant that sells at a loss.

How to read it

1. The box spans the middle half of your models' margins (Q1 to Q3) — where most variants land.
2. The line inside the box is the median — the typical variant.
3. The whisker caps mark the lowest and highest margin across the models.
4. The blue square is the mean (the average), so you can see when a few outliers are pulling it away from the median.
5. Hover the chart to read every value; a product whose models all earn the same margin shows just the number, with no chart.

Why it matters

• A wide spread is a flag: some variants are far less profitable than the average suggests — worth a closer look before you scale ads or discounts.
• The median vs. mean gap tells you whether a couple of extreme variants are skewing the picture.
• In the unified view, the same chart compares one product's margin across marketplaces, exposing where a platform's fees quietly erode it.
