Gross Margin
Gross margin is the percentage of revenue remaining after subtracting cost of goods sold — the primary profitability metric in apparel merchandising that measures how effectively a brand converts product sales into profit before operating expenses.
What is gross margin?
Gross margin is the percentage of revenue remaining after subtracting the cost of goods sold (COGS). Expressed as a percentage — (Revenue - COGS) / Revenue — gross margin is the primary profitability metric in apparel merchandising. It measures how effectively a brand converts product sales into profit before accounting for operating expenses like rent, payroll, marketing, and logistics.
In apparel, gross margin is shaped by a complex chain of decisions: initial markup at the style level, markdown cadence throughout the selling season, channel mix (DTC vs. wholesale), return rates, shrinkage, and the cost structure of the supply chain. A brand with a 60% gross margin retains $0.60 of every dollar in revenue after paying for the product itself — but that figure represents the net outcome of thousands of individual pricing, buying, and markdown decisions.
Gross margin is distinct from contribution margin (which subtracts variable costs like fulfillment) and operating margin (which subtracts all operating expenses). In merchandising planning, gross margin is the metric that merchandising teams own and are held accountable for — it reflects the quality of their buying, pricing, and inventory management decisions.
Why gross margin matters in apparel
-
Profitability baseline: Gross margin establishes the ceiling for operating profitability. A brand cannot sustain healthy EBITDA if gross margin is structurally too low to cover operating expenses. Every point of gross margin directly flows to the bottom line when operating costs are held constant.
-
Pricing strategy validation: Gross margin reveals whether a brand's pricing architecture is working. High initial markups that erode through deep markdowns may produce the same net margin as moderate markups with strong sell-through — but the latter indicates a healthier business.
-
Channel mix impact: DTC sales typically deliver 65–75% gross margins, while wholesale delivers 45–55% after negotiated discounts and chargebacks. Channel planning decisions directly alter the blended gross margin, making it essential to plan margins by channel rather than relying on a single blended target.
-
Buy decision accountability: Gross margin at the style level reveals which products generated profit and which destroyed value. Styles that required steep markdowns to clear may have generated revenue but contributed negative margin after accounting for the markdown cost.
-
Investor and board metric: For brands seeking investment or managing board expectations, gross margin trajectory is one of the first metrics evaluated. Improving gross margin signals pricing power, operational efficiency, and merchandising discipline.
Gross margin in practice: apparel example
A women's contemporary brand targets a 62% blended gross margin for Fall/Winter. The merchandise financial plan breaks this into channel targets: DTC at 70% and wholesale at 52%. Within DTC, full-price sales achieve 74% margin, but the 30% return rate and 15% of sales at markdown compress the blended DTC margin to 70%. The wholesale target of 52% accounts for account-specific discounts, markdown allowances, and co-op contributions. During the season, the merchandising team monitors gross margin weekly by category and channel. When the knit tops category shows margin erosion from aggressive early markdowns, the team adjusts the strategy — shifting to targeted promotions on specific styles rather than category-wide discounting — protecting the remaining full-price inventory and recovering 200 basis points of margin in the second half of the season.
Common mistakes
-
Confusing initial markup with gross margin: IMU is the planned margin at the time of purchase. Gross margin is the realized margin after markdowns, returns, shrinkage, and allowances. The gap between IMU and realized gross margin is the true measure of in-season margin erosion.
-
Planning margin without planning markdowns: Gross margin targets are meaningless without a corresponding markdown budget. If the plan assumes 60% gross margin but does not explicitly plan for the markdowns needed to achieve seasonal sell-through, the target is fiction.
-
Ignoring freight and duty in COGS: Some brands calculate gross margin using landed cost (including freight, duty, and import costs) while others use first cost only. Inconsistent COGS definitions make cross-period and cross-brand comparisons unreliable.
-
Optimizing margin at the expense of volume: Raising prices or cutting promotions may improve gross margin percentage while reducing total gross margin dollars. Merchandising teams must balance margin rate with revenue volume to maximize total profit contribution.
In RetailNorthstar: Gross margin is planned and tracked at every level — brand, department, category, style, and channel — with real-time visibility into the gap between planned and actual margin, so merchants can intervene before end-of-season markdowns erode profitability.
