Quick answer: Cashmere sweaters are expensive because usable fine undercoat is limited, cleaning and dehairing reduce the fibre yield, and skilled spinning, knitting, finishing and testing add cost. The premium is justified only when the yarn, construction and finished performance match the price. A “100% cashmere” label confirms composition, not overall quality. It does not reveal fibre length, yarn specification, garment weight, stitch density, finishing quality or production control. That is why two sweaters carrying the same label can have very different prices and wear performance. For a shopper, the practical question is whether the sweater feels good, keeps its shape and suits the intended care routine. For a fashion founder or buyer, the same question becomes more precise: which yarn, construction and controls created that result, and can the cashmere sweater manufacturer reproduce it in bulk? The Short Version: What You Are Paying For ...
Why can one wool sweater cost $12 while another costs $25 or more at the factory?
The answer is rarely just labour.
Fibre composition, garment weight, knitting gauge, colour quantity, washing, trims and quality requirements all affect the final quotation. To show how these variables work together, we reviewed a defined production case: a 350g, 100% wool sweater with a factory price of USD 19.
The estimated production cost is USD 16.41 per garment, leaving approximately USD 2.59 in gross factory margin.
This case gives fashion brands a practical way to understand wool sweater manufacturing cost without relying on vague industry averages.
The Production Case Behind the Numbers
This cost model uses yarn pricing and production inputs supplied by the YouTricot production team in Dongguan, China.
The garment specification is:
100% wool
2/26Nm yarn
12GG construction
350g finished garment weight
500-piece order
Five colours
100 pieces per colour
Softening wash
Shrink-control treatment
Hand-feel finishing
USD 19 factory price
The wool yarn purchase price used in the calculation is RMB 230 per kilogram. Currency conversion is based on a model exchange rate of USD 1 to RMB 7.20.
These figures describe one factory costing scenario, not a universal market price. Yarn prices, exchange rates, labour charges and finishing costs can change over time.
The Simplified Cost Structure
The complete calculation contains multiple production lines, but the cost can be understood through four main groups.
| Cost group | Approximate cost per sweater |
|---|---|
| Wool yarn and production allowance | USD 12.08 |
| Knitting, linking, washing and finishing | USD 2.68 |
| Trims, packaging and quality control | USD 0.60 |
| Equipment, management and handling | USD 1.04 |
| Total production cost | USD 16.41 |
| Factory gross margin | USD 2.59 |
| Factory price | USD 19.00 |
Figures in the grouped rows are rounded. The complete calculation is available in YouTricot’s original USD 19 wool sweater cost breakdown.
Why Wool Yarn Represents Most of the Cost
The finished sweater weighs 350g, but the factory cannot calculate material cost using finished weight alone.
Additional yarn is needed for machine setup, tension adjustment, test panels, yarn ends, panel repair and production loss.
This case uses an 8% production allowance:
350g × 1.08 = 378g
At RMB 230 per kilogram:
0.378kg × RMB 230 = RMB 86.94
At the model exchange rate, the wool yarn costs approximately USD 12.08 per garment.
Yarn therefore represents about 73.6% of the total production cost.
This explains why two sweaters that look similar in a photograph can have very different quotations. A lower price may be based on a lighter garment, a wool blend, a lower yarn grade or a different production allowance.
Buyers should confirm the exact fibre composition and finished weight before comparing prices.
What Does 12GG Mean for Production?
A 12GG sweater is classified as fine gauge knitwear. It usually has a cleaner, more refined surface than a 3GG or 5GG chunky sweater.
Gauge alone does not determine cost. A factory must also consider:
Yarn count
Number of yarn ends
Stitch density
Garment measurements
Knitted structure
Machine time
Washing shrinkage
Pattern complexity
A basic 12GG jersey sweater is more efficient than a 12GG style with intarsia, jacquard, pointelle or complex fully fashioned shaping.
Before bulk production, the selected yarn should be tested on the intended machine. The factory should check stitch formation, tension, garment measurements and the result after washing.
Why Five Colours Cost More Than One
The order contains 500 pieces, but it is divided into five colours. Each colour has only 100 pieces.
Every colour requires separate production work:
Yarn allocation
Machine setup
Colour identification
Batch management
Separate washing
Colour comparison
Packing checks
A single-colour order of 500 pieces normally has better production efficiency than five colours of 100 pieces.
This is particularly important when working with a low MOQ knitwear factory. Total order quantity does not tell the complete story. Quantity per colour often has a greater effect on efficiency, especially when yarn must be custom dyed.
For private label knitwear, brands can control costs by selecting available yarn colours, reducing the number of launch colours or increasing the quantity of the strongest commercial colour.
Why Washing and Finishing Matter
The garment in this case receives softening, shrink-control and hand-feel treatments.
These processes influence:
Surface softness
Dimensional stability
Stitch definition
Garment shape
Final presentation
Customer perception
Washing is not simply a cosmetic step. Wool can react to moisture, heat and mechanical action, so the process must be tested and controlled.
ISO 5077 provides a standardized method for determining dimensional change after washing and drying. The standard explains how change is measured; it does not guarantee that every garment will achieve the same shrinkage result.
Shrink-control treatment also does not automatically make a sweater machine washable. Care instructions should reflect the tested garment. Woolmark recommends checking the care label and generally advises flat drying unless the label specifically permits another drying method. Its official wool care guidance provides practical consumer instructions.
Why Quality Control Should Not Be the First Cost Removed
Quality control is one of the smaller lines in the cost model, but its commercial effect can be much larger than its unit cost.
Routine knitwear quality control may cover:
Yarn-lot consistency
Panel measurements
Linking quality
Finished measurements
Surface defects
Colour differences
Garment weight
Label placement
Packing accuracy
Removing inspection may save a few cents but increase the risk of returns, replacements and damaged brand reputation.
Laboratory testing and third-party inspection are usually quoted separately. Buyers requiring pilling, colour-fastness, fibre-content or harmful-substance testing should agree on the test method and acceptance standard before production.
Is the $2.59 Factory Margin Pure Profit?
No.
The difference between the USD 19 factory price and the USD 16.41 production cost is gross margin, not final net profit.
The gross margin is approximately:
USD 2.59 ÷ USD 19 = 13.6%
That margin still needs to absorb risks such as:
Currency movement
Reworking
Replacement pieces
Machine downtime
Material delays
Payment terms
Quality claims
Production rescheduling
A reliable knitwear manufacturer needs a reasonable margin to maintain equipment, retain skilled employees and take responsibility when production problems occur.
Transparency does not mean a factory should work without profit. It means the buyer understands what is included and why the quotation is commercially sustainable.
Could the Same Sweater Be Quoted at $15?
Not under the same assumptions without creating a loss or changing the product.
At the model exchange rate, USD 15 equals RMB 108. The estimated production cost is RMB 118.14, creating a shortfall of RMB 10.14 per sweater.
To reach a lower target price, at least one variable would need to change:
Fibre composition
Garment weight
Yarn purchase price
Colour quantity
Washing process
Packaging
Order volume
Production scope
Commercial terms
A lower-priced wool blend can be a valid choice when its composition is clearly disclosed and approved. Quietly reducing wool content or garment weight is not a responsible cost-saving method.
What Buyers Should Check Before Comparing Quotations
When brands ask how much does custom knitwear cost, they should provide enough information for factories to quote the same product.
Before comparing suppliers, confirm:
Exact fibre composition
Yarn count and yarn grade
Finished garment weight
Gauge and stitch structure
Quantity per style
Quantity per colour
Washing and finishing requirements
Labels and trims
Packaging requirements
Testing and inspection standards
Sample approval process
Trade terms
A low quotation may exclude washing, trims, inspection or export handling. It may also use a different garment weight.
For international orders, buyers should check whether the quotation is EXW, FOB or based on another term. The ICC Incoterms 2020 rules are the authoritative reference for how costs and risks are allocated between buyer and seller.
FAQ
What is the manufacturing cost of the wool sweater in this case?
The estimated production cost is USD 16.41 per garment. The factory price is USD 19, leaving approximately USD 2.59 in gross margin.
How much yarn is allowed for a 350g sweater?
This model allows 378g per garment after adding an 8% production allowance. Actual consumption should be confirmed after sampling, grading and washing.
Is 2/26Nm yarn suitable for 12GG knitting?
It can be, but suitability depends on the number of yarn ends, stitch density, structure and target hand feel. The yarn should be tested on the intended knitting machine before bulk production.
Why does a five-colour order increase manufacturing cost?
Each colour requires setup, tracking, separate washing and inspection. Five batches of 100 pieces are less efficient than one batch of 500 pieces.
Does the USD 19 price include international shipping?
Not automatically. The buyer must confirm whether the price is EXW, FOB or based on another commercial term.
How can brands reduce wool sweater cost responsibly?
Brands can reduce colour count, increase quantity per colour, use available yarn colours, simplify packaging or adjust garment weight. Essential quality control and accurate fibre disclosure should remain in place.
The Lowest Price Is Not Always the Lowest Risk
In this case, most of the USD 19 factory price goes into the product itself.
Approximately USD 12.08 pays for wool yarn. Around USD 4.33 covers knitting, washing, finishing, trims, quality control and factory operations. The remaining USD 2.59 is gross factory margin.
A transparent cost structure gives buyers something more useful than a low headline price. It shows which parts of the product can be adjusted and which reductions may compromise quality.
