What Really Affects Sweater Factory Price? 7 Cost Factors Explained

By YZR Sweaters · 2026-09

Every buyer has had the same experience: you ask three suppliers for a quote and get three very different numbers. A $12 sweater and a $20 sweater can look almost identical in a photo, yet be entirely different garments. Understanding what drives the cost lets you compare quotes accurately and avoid paying extra for the wrong things — or worse, buying a cheap sample that falls apart in production.

Here are the seven factors that most influence a sweater factory's price, explained plainly.

1. Yarn composition

The yarn is the largest single cost and the biggest driver of how the sweater feels. Wool, cashmere and their blends cost more than acrylic and polyester. A 100% cotton or viscose knit sits in between. The same style can more than double in price just by switching from an acrylic blend to a premium wool-cashmere blend.

When comparing quotes, always check that the yarn composition is genuinely the same. A cheap quote often uses a different material than you think.

2. Ply and yarn count

"Ply" refers to how many strands are twisted together, and the yarn count tells you how fine or thick the yarn is. A finer, higher-count yarn generally costs more because it uses more fiber and often requires more careful handling. A two-ply or three-ply yarn adds warmth and durability but also adds cost.

This is one of the most common places where a low quote hides a trade-off — a lighter ply yarn can undercut the price while changing the hand-feel you approved in the sample.

3. Gram weight

Gram weight is the weight of the fabric per square meter, and it's a direct measure of how substantial the sweater feels. A heavier knit uses more yarn, so it costs more. It also affects warmth, drape and how the garment carries a brand's premium positioning.

If you're comparing two similar-looking sweaters, check the gram weight. A big difference there explains a lot of the price gap.

4. Knitting and stitch complexity

How the sweater is knitted has a big impact on production time and cost. A plain single-jersey knit is quick and affordable. A double jersey, a jacquard pattern, a cable knit or intarsia work consumes more machine time and requires more skill, so it's priced higher.

More complex stitching also means more quality control, which is worth it if that texture is central to your design — but don't pay for a jacquard when a simple rib would do.

5. Size and number of sizes

A larger garment uses more yarn and more labor, so it costs more to produce. The number of sizes you order also matters. A size run with many variations — especially if you add plus sizes or children's sizes — increases setup and grading work.

Wide size ranges are frequently requested but often underestimated in cost. Be clear about your range early so the quote reflects it accurately.

6. Quantity and how costs are spread

Fixed costs — sample development, machine setup, yarn ordering and other overheads — are spread across your order. A larger quantity lowers the unit price; a smaller run raises it. This is exactly why flexible MOQ comes with a slightly higher per-piece cost.

If you're choosing between a small trial run and a big commitment, understand that the first order will carry a higher unit cost, and that's usually the right price to pay to de-risk before scaling.

7. Trims and finishing

It's not just the knit. Buttons, zips, drawcords, ribbed collars, and finishing touches like a branded woven label or hang tag all add up. Finishing treatments, the way the sweater is blocked and steamed, and the quality of the seams influence both the price and the premium look of the garment.

Ask the supplier to itemize trims and finishing so you can see where the value sits rather than just chasing a headline number.

How to protect yourself from a too-good price

The single most useful thing you can do is ask the supplier how they achieve their price. If a quote is far below everyone else, there's usually a reason: thinner yarn, a different ply, a lighter gram weight, simpler stitches, or a plan to substitute material after you've paid.

Compare quotes on the same specification, not just the same style name. Ask each supplier to confirm the yarn, ply, gauge, gram weight and trim in writing, and keep a reference sample so the bulk order is measured against what you approved.

Finally, don't fixate on the lowest unit cost alone. Fast sampling, honest communication, consistent quality and reliable delivery often save you more over a season than a few cents per piece.
