A garment bill of materials lists every material needed to make a style, with specification, placement, consumption and supplier. How to structure a BOM, calculate quantities by color and size, and avoid the errors that cause shortages.
CM (cost of making) covers cutting, sewing and finishing. Learn how to build a cost per minute from factory costs, calculate CM from SMV and efficiency, and avoid the assumptions that make CM quotes lose money.
FOB price is what the buyer pays for goods delivered on board at the port of shipment. What FOB includes and excludes, how to build an FOB price from fabric, trims, CM and overheads, a worked example, and how FOB compares with other shipping terms.
How to calculate fabric consumption for knit garments (by weight, from panel areas and GSM) and woven garments (by length, from the marker), with worked examples, wastage allowances and the mistakes that cause fabric shortages.
A garment cost sheet adds fabric, trims, cost of making, processes, testing, commercial costs and profit to reach a price. This guide walks through each element with a worked T-shirt example and the checks that stop losses.
The panel method for knit fabric consumption: list every panel, calculate area and weight by fabric, add allowances, and total by kg per dozen. Worked example for a hoodie with body fabric and rib.
The body block method for calculating fabric consumption of a basic T-shirt in kg per dozen, with a worked example, how to handle neck rib, size ratios and wastage, and how to check the estimate against a marker.
How to calculate sewing thread consumption per garment using seam lengths and measured thread-to-seam ratios for each stitch type, then convert it into cones per order by color and ticket.
