Price and cost architecture

Pricing garments

A garment price has to perform three jobs at once: recover the cost of bringing the product to market, support the brand’s commercial model and feel credible to the intended customer. Begin with the landed unit cost rather than fabric cost alone. Include materials, trims, direct labour, finishing, labels, packaging, quality control, freight, duties and other costs required to bring the item to its saleable condition. IAS 2 similarly treats inventory cost as purchase, conversion and other costs incurred to bring inventory to its present location and condition.[5]

Next, identify the channel and market position. A direct-to-consumer price, a wholesale price and a marketplace price may have different commissions, fulfilment costs, return exposure and margin requirements. Map comparable products by category, material, construction, origin, service and brand position; compare like with like rather than copying the lowest visible price. Cost-plus pricing provides a baseline, but Shopify’s pricing guidance also recommends testing production cost, customer value, market conditions and positioning together.[3]

Use the correct formula for the objective. If the desired gross margin is expressed as a percentage of the selling price, calculate target price = unit cost ÷ (1 − target gross-margin rate). A €40 cost at a 60% target gross margin produces a €100 price before tax. Do not multiply €40 by 1.60: that creates a 60% markup on cost but only a 37.5% margin on sales. Round only after completing the calculation, then test the result against tax treatment, planned promotions, returns, wholesale terms and psychological price thresholds.

Create a price ladder across the collection: entry, core, premium and statement levels should each have a clear product role. Check price gaps between related styles and make sure higher prices are supported by visible or explainable value—better material, greater craft, improved function, scarcity, service or brand meaning. Keep discounts in the plan rather than using an artificial reference price; advertised prices and comparisons must be truthful and clear under the rules that apply in the selling market.[12]

Applied exercise: Price five connected garments for both direct-to-consumer and wholesale scenarios. Record landed cost, channel costs, target margin, calculated price, proposed final price, competitor range and customer-value justification. Stress-test every style at full price, a planned markdown and a 10% cost increase.

Cost sheets

A cost sheet is the controlled financial record of how a specific style, colourway, quantity and production version reaches its unit cost. It should connect to the technical pack and bill of materials, not sit as an isolated spreadsheet. FIT’s fashion-business curriculum links bills of materials and product processes to garment prototypes, while its product-costing course covers estimating, capturing actual costs and analysing variance from the standard.[1][2]

Start the header with style number, description, season, version, supplier, factory, country of origin, order quantity, size basis, currency, quotation date and trade terms. Then itemise:

  • Materials: shell, lining, interfacing, rib, thread and other components, each with unit of measure, consumption, unit price, wastage and total.
  • Trims and packaging: fasteners, labels, hangtags, tissue, bags, cartons and any retail-ready requirements.
  • Making and finishing: cutting, sewing or CMT, washing, printing, embroidery, pressing and specialist processes.
  • Pre-production and quality: pattern, grading, sampling, testing, inspection and compliance costs, allocated according to the company’s method.
  • Landed-cost additions: inland transport, freight, insurance, duties, brokerage and handling where relevant.

Document the evidence behind every number: supplier quote, marker yield, sample consumption, standard minute value, freight estimate or tariff classification. Label figures as estimate, quoted, approved or actual. Never mix currencies or units silently, and show whether taxes are recoverable. Add an assumptions field for minimum order quantities, exchange rate, expected waste and freight method so another team member can reproduce the calculation.

Re-cost at defined gates: initial design, first prototype, supplier quotation, pre-production sample and post-production close. Calculate variance as actual cost − standard cost, then identify whether the difference came from price, usage, quantity, process or currency. A cost sheet is useful only when changes to fabric consumption, trim, construction or order volume trigger a new version and a price or margin review.

Applied exercise: Build one complete cost sheet from a finished sample. Attach evidence for the three largest inputs, compare estimated and actual consumption, and propose one cost reduction that preserves fit, quality, safety and the product’s design intention.

Margin and investment control

Profit margins

Margin analysis shows what remains after specific costs, so always name the level being measured. Gross profit is net sales minus cost of goods sold; gross margin percentage is gross profit divided by net sales. Contribution margin subtracts the variable costs associated with each sale and is useful for break-even decisions. Operating and net margins then account for wider expenses such as salaries, studio rent, marketing, software, interest and tax. A healthy product gross margin does not automatically mean that the company is profitable.

Use net sales after discounts, returns and allowances, and compare the same period and channel. For one style, calculate gross margin % = (net selling price − product cost) ÷ net selling price × 100. Separately calculate markup on cost % = (selling price − product cost) ÷ product cost × 100. Shopify’s current retail-math guidance treats markup, gross margin, inventory turnover and GMROI as separate calculations, so every analysis must state its numerator, denominator, time period and value basis.[13]

Break-even analysis converts these figures into a volume target. The U.S. Small Business Administration formula is break-even units = fixed costs ÷ (selling price per unit − variable cost per unit).[4] If fixed collection costs are €12,000, the net unit price is €100 and variable cost is €40, the contribution is €60 and break-even volume is 200 units. For a mixed collection, use a realistic sales mix rather than assuming that every style contributes equally.

Create a sensitivity table for price, unit cost, markdown, return rate and volume. A style can meet margin at full price yet fail after promotions and returns; another can have a lower percentage margin but contribute more cash because it sells at greater volume. Review margin by style, category, channel and season, and investigate variance between planned and actual results. Treat targets as company-specific decisions—there is no universal “correct” fashion margin.

Applied exercise: Calculate gross margin, markup and contribution for three styles, then find collection break-even under base, cautious and optimistic sales mixes. Identify the single assumption with the greatest effect and define the action that would reduce that risk.

Collection budgeting

A collection budget translates creative scope into an approved financial envelope and a cash timetable. Build it twice: top-down from the amount the business can responsibly invest, and bottom-up from the resources required by every planned style. The two views must reconcile before commitments are made. Financial planning should include projected income, cash flow and capital needs rather than a single total; the SBA likewise recommends forecast income statements, balance sheets, cash-flow statements and capital-expenditure budgets.[6]

Separate the budget into development, production and launch. Development can include research, design time, pattern cutting, toiles, samples, fittings, testing and photography. Production includes material deposits, manufacturing, inspections, packaging, freight, duties and fulfilment preparation. Launch can include ecommerce assets, showroom or event costs, sales samples, marketing and commissions. Add operating allocations and a visible contingency rather than hiding uncertainty inside individual line items.

Budget by style and by month. For each style, track planned units, development cost, landed unit cost, expected receipts, target net sales and margin contribution. For each month, show deposits, balance payments, freight, launch spend and expected customer or wholesale receipts. Profit on paper cannot pay a supplier deposit before sales income arrives, so mark the highest cash requirement and the date at which it occurs.

Use decision gates: concept approval, sample approval, cost approval, order commitment and launch release. At every gate compare budget, committed spend, actual spend, forecast to complete and variance. Do not justify overspend only because earlier money has already been spent; judge the remaining investment against current evidence. Create a base plan and at least two scenarios for lower demand, delayed delivery or higher input costs.

Applied exercise: Prepare a twelve-week collection budget with style-level and cash-flow views. Mark payment dates, contingency, approval gates and committed versus uncommitted spend. Rework the range after a simulated 15% budget reduction without removing the collection’s central customer proposition.

Product and retail planning

Product planning

Product planning decides which garments should exist, for whom, at what price, in which options and on what delivery. Start with the customer, occasion, climate, channel and problem to solve. Translate these into an assortment matrix containing category, style role, silhouette, fabrication, colour, size range, price tier, delivery window and intended quantity. The aim is a coherent system of products—not the largest possible number of sketches.

Distinguish breadth, the range of product lines or categories, from depth, the number of choices within them. Shopify’s assortment guidance describes the same breadth-and-depth relationship and notes that an intentional mix helps limit dead stock and stockouts.[7] In fashion, depth multiplies quickly: one style in three colours and six sizes creates eighteen SKUs. Count styles, colourways and SKUs separately before approving the range.

Give every product a role: hero, image-maker, core, entry price, commercial volume, outfit connector or experimental test. Map price points and use occasions to find duplication and gaps. Then test feasibility against blocks, fit resources, fabric minimums, supplier capacity, lead time, testing and delivery. FIT’s fashion-business curriculum connects forecasting with product-line planning, while its assortment-planning courses move from category and class decisions to SKU-level production buys.[1]

Create a line plan and development calendar. Work backward from the selling date through delivery, production, pre-production approval, fit, costing, material booking and design freeze. Define exit criteria for each stage: a sketch should not enter sampling without a brief and target cost; a sample should not enter production without fit, quality, cost and demand approval. Record what is carryover, updated or new so that development risk is visible.

Applied exercise: Build a ten-style assortment matrix and calculate its total colourways and SKUs. Label every product role, price tier and delivery, then remove one redundant option and add one evidence-based gap. Present the result as a line plan and a backward-timed critical path.

Retail planning

Retail planning converts the assortment into sales, stock and receipt targets over time. Begin with historical net sales, units, full-price sell-through, returns, markdowns and stock by category and channel. Add known changes in distribution, price, promotion, seasonality and delivery. New labels without history should document the assumptions behind their forecast and update them quickly as real trading data arrives.

Build a monthly or weekly plan with beginning inventory, planned sales, planned markdowns, planned ending inventory and receipts. A common retail open-to-buy calculation is OTB = planned sales + planned markdowns + planned ending inventory − planned beginning inventory; subtract on-order goods when they are not already included in planned receipts. Keep retail-value and cost-value plans separate and state which basis is used. Shopify’s current OTB guide explains retail-, cost- and unit-based approaches and recommends aligning the method with margin, cash-flow and replenishment needs.[8]

Plan at collection, category and SKU levels. A total sales target can conceal too much inventory in one colour and insufficient depth in another. Allocate sizes and locations using evidence, not equal division, and distinguish replenishable core stock from seasonal fashion risk. Include supplier lead time, minimum order, reorder point and delivery reliability. Review the plan in season and move, replenish, remerchandise or mark down stock according to defined thresholds.

Use consistent measures: sell-through compares units sold with units received or available during a stated period; weeks of supply estimates how long current stock will last at the forecast sales rate; inventory turnover relates sales or cost of goods sold to average inventory on the same value basis; and GMROI = gross margin currency ÷ average inventory cost. Shopify includes sell-through, turnover and GMROI among core retail efficiency measures.[9]

Applied exercise: Create a six-month retail plan for three categories. Calculate OTB, sell-through, weeks of supply and GMROI using explicitly defined inputs. At the mid-season review, respond to one bestseller, one slow colourway and one delayed delivery without exceeding the buying budget.

Merchandising and feedback

Merchandising basics

Merchandising is the coordinated work of selecting, pricing, presenting, promoting and measuring products so the intended customer can discover and buy them. The classic planning objective is the right product, quantity, time, price and place. Modern fashion merchandising connects the range plan, inventory and brand story across ecommerce, social commerce, wholesale and physical retail rather than treating display as a final decoration.[10]

Start with customer intent and product hierarchy. Choose the collection story, hero product, commercial anchors, outfit builders and add-on items. Group products by a logic the customer understands—occasion, silhouette, colour, fabrication or use—while retaining practical navigation by category, size and price. Ensure that photography, naming, descriptions, fit information, material details, care and availability answer the questions required for a confident decision.

Apply visual hierarchy to both store and screen. Establish a focal point, give important products breathing space, repeat a controlled palette and guide the eye from story to product detail to purchase action. Style complete looks, but keep individual items easy to identify and buy. Digital merchandising must also work on a small screen: prioritise the strongest image and essential information, keep tap targets clear and avoid hiding core product facts behind presentation effects. Shopify defines product merchandising as intentional promotion, display and sale across physical and digital environments.[11]

Build a merchandising calendar around deliveries, campaign moments, events, climate and stock position. Link each promotion to an objective and inventory reality; do not create demand for unavailable product or rely on discounts to solve unclear value. Coordinate homepage, collection pages, product pages, email, social content, windows and sales materials so price, availability and claims remain consistent.

Measure the full journey: product-page engagement, conversion, average order value, units per transaction, full-price sell-through, return rate, markdown rate, gross margin and GMROI. Compare product and channel performance without letting one metric dominate. High conversion with high returns may signal poor fit information; strong traffic with weak add-to-cart may indicate price, imagery or proposition problems. Feed the findings back into pricing, assortment, depth, replenishment and the next collection brief.

Applied exercise: Create a merchandising plan for one launch across a mobile collection page and a physical or wholesale display. Define the focal product, navigation, outfit groupings, information hierarchy, calendar, inventory constraints and five success measures. Conduct a small-screen readability check and document two changes made from the results.
