Costing Formula
Financial calculations in apparel sourcing reconcile the weight and length of imported fabric against the final garment output. The landed yield arithmetic determines the true cost per linear meter or yard of fabric after accounting for transportation, duties, shrinkage, and cutting waste. Sourcing managers use this method to compare raw mill prices with the actual cost of usable fabric delivered to the garment factory.
It exposes the hidden costs of purchasing cheaper, low-quality fabrics that suffer high waste. By integrating the physical yield with the landed shipping costs, this math allows brands to calculate the exact fabric cost per finished garment unit, which is the baseline for retail pricing.
Commercial Risk
Shipping costs and import tariffs can distort the initial purchase price of textile raw materials. A low mill gate price can become expensive if the fabric has a high weight per square meter, which raises shipping fees. Furthermore, high defect rates in the shipped rolls require the factory to cut around flaws, which reduces the effective yield of the fabric.
This reduction increases the cost per garment.
Yield Optimization
Calculations must run before placing bulk orders to avoid budget overruns in the factory. The formula incorporates the fabric density, cuttable width, and expected wash shrinkage to predict the total roll consumption. If the calculations are incorrect, the garment factory may run out of fabric before completing the order, forcing them to purchase expensive replacement air shipments.
This risk makes the mathematical model indispensable.
Sourcing Metric
Sourcing teams use this numerical analysis to negotiate better terms with fabric mills. By showing the mill the high cost of processing their low-yield fabrics, buyers can demand discounts or tighter quality tolerances. This metric ensures that purchasing decisions are based on total cost rather than simple unit price.
