What this means for your catalog

This is one SKU. Most ecommerce brands have 20–150 SKUs across 2–4 channels — and the blended margin hides which ones are destroying the portfolio.

19.6% CM puts this SKU in the danger zone. One fee increase or return spike tips it negative.

How we calculate

Return-adjusted contribution margin = net revenue (after returns) minus COGS, channel fees, and ad spend. Not gross margin. Not ROAS. Auditable arithmetic.

Net Revenue = Price × Units × (1 − Return%)
CM $ = Net Revenue − (All-in Cost × Units) − (Net Revenue × Fees%) − Ad Spend
CM % = CM $ ÷ Net Revenue × 100
