Ask five textile production managers what it actually costs to make one kilogram of yarn, and it is common to get five different answers, each one leaving out a different piece of overhead. Getting cost per unit right is not an accounting exercise, it directly decides whether a quote wins a contract at a profit or wins it at a loss that only shows up months later. Accurate costing at the yarn, fabric, and garment level is the single biggest lever most mills have for protecting margin without changing a single machine on the floor.

The Three Layers of Every Product Cost
Yarn, Fabric, and Garment: Where Cost Structures Diverge
| Product Stage | Dominant Cost Driver | Typical Costing Unit | Common Costing Mistake |
|---|---|---|---|
| Yarn | Raw fiber and count | Cost per kg | Ignoring count-wise waste variation |
| Fabric | Weaving/knitting efficiency | Cost per meter | Averaging efficiency across all looms |
| Dyed/Processed Fabric | Chemical and process cost | Cost per meter | Not isolating shade-wise chemical cost |
| Garment | Labor minutes (SAM) | Cost per piece | Using flat labor rate across styles |
Five Questions Every Cost Sheet Should Answer
What Accurate Costing Actually Protects
Frequently Asked Questions
A single average cost per kilogram across all counts and constructions hides real differences in waste percentage, machine efficiency, and processing time between products, meaning a low-margin product looks acceptable while a high-margin one gets underpriced to compensate. This blending effect is one of the most common reasons a mill's overall numbers look healthy while individual orders are actually running at a loss. Book a demo to see product-level costing instead of blended averages.
Allocating fixed overhead based on actual machine hours consumed by each product, rather than splitting it equally or by volume alone, generally produces the most accurate picture, since products that run slower or require more machine time genuinely do carry more overhead burden. A simple equal split across all products systematically overcharges fast-running items and undercharges slow ones, distorting which products actually deserve a price increase.
Contribution margin is what remains after subtracting only the variable cost of a product from its selling price, and it tells you directly whether producing more of that item helps overall profitability, independent of how fixed costs happen to be allocated. Gross margin, which includes allocated fixed costs, can make a genuinely profitable product look weak simply because of how overhead was split, which is why contribution margin should drive volume decisions while gross margin informs overall pricing strategy.
Raw material rates should feed into cost sheets as close to real time as possible, since cotton and yarn prices can move meaningfully within a single quarter, and a quote built on a two-month-old rate can already be underpriced before the order is even confirmed. Labor and overhead rates change more slowly and can reasonably be reviewed monthly or quarterly, but material cost is the component that erodes margin fastest when left stale. Contact support to automate cost sheet updates.
Not directly, garment costing is driven primarily by labor minutes, commonly measured as standard allowed minutes per style, rather than material and machine efficiency the way yarn and fabric costing are. A flat per-piece labor rate applied across styles of very different complexity is one of the most common garment costing errors, since a simple style and a heavily embellished one can require dramatically different labor time despite carrying the same nominal rate.
