E-commerce product profitability: which SKUs create real economic value
Two products with the same revenue can make very different economic contributions. Product profitability needs reliable COGS and clear cost coverage before it becomes a useful decision tool.
Net Revenue − COGS − Shipping − Payment Fees − Ad Spend − Other Costs= Estimated ProfitProduct revenue is not contribution
A best seller can generate large revenue but weak margin because of unit cost, discounts, shipping or expensive acquisition. A smaller product can create a stronger contribution. Useful comparison starts from real product cost rather than quantity or sales value alone.
COGS is the foundation of product profit
Without product cost, SKU profitability is incomplete. It is better to have reliable COGS for the products responsible for most sales and show coverage than to display artificial profit for products with no recorded cost.
Use margin for comparison
Contribution in euros shows the absolute result of a product. Margin helps compare items with different prices and revenue. Reviewing both can expose products that increase total sales while compressing the economic performance of the catalog.
Catalog decisions need context, not a single ranking
Profitability data does not replace product strategy. Stock availability, repeat purchase, brand value and acquisition role can also matter. Kepio adds economic context so product decisions do not rely on revenue alone.
✓ Unit cost / COGS by product
✓ Product-cost coverage before conclusions
✓ Contribution and margin together
✓ Best sellers first for faster accuracy
Frequently asked questions
Do I need COGS for every product?
Not to begin, but product-profitability confidence depends on coverage. Start with SKUs generating most of the revenue.
Is a high-revenue product always better?
No. Unit cost, discounts and other related costs can produce a much weaker economic contribution.
Can I compare margin by product?
Yes, when COGS methodology and relevant costs are applied consistently.
