Understanding Gross Margin
What gross margin measures
Gross margin = (Revenue − COGS) / Revenue. It is the share of each sale left after the direct cost of the product, before overhead and marketing. It is the headline number for product-level profitability.
Margin vs markup again
A 40% gross margin equals a ~67% markup on cost. Always confirm which one a supplier or marketplace is quoting — confusing them quietly erodes profit.
Defending your margin
Price competition is the fastest way to lose gross margin. Monitoring competitors lets you hold price where the market allows and only discount when you must — protecting the margin this calculator measures.
