Use this estimator to sanity-check a target cost before you send a brief. It applies the same cost drivers a factory quotation does — fabric, order quantity, colour count and packaging — and shows what the fixed set-up cost does to your per-piece price at your volume. Based in Xiamen, Fujian Province, in the Xiamen–Quanzhou–Jinjiang knitwear cluster of south-east China, Unitex manages sampling, quality control and export documentation for every order.
Estimate your unit cost
Assumptions behind the estimate
- Base cost per piece: boxer brief US$1.55, brief US$1.35, trunk US$1.65, sleepwear set US$5.60, sport bra US$3.40 (FOB China, standard construction).
- Fabric multiplier: combed cotton 1.00, micro modal 1.15, bamboo viscose 1.12, polyamide microfibre 1.20.
- Quantity curve: under 1,000 pcs +30%, 1,000–1,999 +18%, 2,000–4,999 +8%, 5,000–9,999 baseline, 10,000–24,999 −6%, 25,000+ −10%.
- Colourways: the first two are included; each additional colour adds about 2.5% because of dyeing minimums.
- Packaging: polybag included; boxed set +US$0.35 per piece; custom hangtag +US$0.06.
- Set-up: US$500–1,000 per new style (dyeing minimums, cutting changeover, line set-up, pre-production sample), spread across your order quantity.
- Excluded: freight, duties, testing, buyer-supplied trims, and anything outside a standard specification.
This is an estimator, not a quotation. Real prices depend on your exact specification, fabric weight and finish, packaging artwork and current material prices. Send a brief or a reference sample and we return a costed quotation with a dated production plan.

|---|---|

| Variable cost | Fabric, trims, labour and packing, proportional to quantity |
| Threshold effect | Unit price falls steeply up to the minimum and flattens above it |
| Colour effect | The minimum applies per colour, so four colours means four thresholds |
| What changes the estimate | Fabric price, consumption, colour count and construction detail |
Buyer checklist
- Split the quote into fixed and variable parts before comparing
- Check whether the minimum applies per colour or to the order total
- Model the unit price at the minimum and at roughly double it
- Confirm consumption and fabric price separately from labour
- Count the colourways, since each one carries its own threshold
- Re-run the estimate when construction or fabric changes
