Garment costing is where most brands either protect their margin or quietly lose it. After 20+ years costing export orders in Tirupur, this is how apparel costing actually works, from the weight of the fabric all the way to the buyer price, along with the types of costing in the garment industry and a worked garment costing sheet you can follow. The example numbers below are illustrative, but the method is exactly the one a real factory uses.
What Is Costing in the Garment Industry?
Costing in the garment industry is the process of calculating the total cost to produce one garment, so a manufacturer can quote a price and a brand can plan its margin. It is not a single number pulled from experience; it is a structured build-up of every input that goes into the piece, from grams of yarn to the labels sewn into the neck. Done properly, apparel costing is what separates a factory that holds its margin from one that discovers, too late, that it priced an order at a loss.
The 8 Types of Costing in the Garment Industry
Before the line-by-line build-up, it helps to know the types of costing used across the industry. Different situations call for different approaches.
- Cost sheet costing: the standard line-by-line build-up of every input, used for most quotations.
- Marginal costing: looks at the additional cost of producing one more unit, useful for deciding whether to accept extra volume.
- Standard costing: uses pre-set standard rates for materials and labour, then compares actuals against them.
- Absorption costing: spreads all overhead across every unit so nothing is left unaccounted.
- Activity-based costing: assigns overhead based on the actual activities a garment consumes, giving a more accurate picture for complex styles.
- Job costing: costs a specific order or job as a self-contained unit.
- Process costing: averages cost across a continuous production process, suited to high-volume basics.
- Target costing: starts from the price the market will pay and works backwards to the cost the factory must hit.
In practice, most export quotations are built using cost sheet costing, which is what the rest of this guide walks through.
How to Cost a Garment: The Real Build-Up
A garment cost is assembled in a clear sequence, and there is no single garment costing formula that captures it, only a disciplined order of steps. Each stage feeds the next, and the biggest single cost is almost always the fabric. Here is the order it is actually built in.
Step 1: Fabric consumption and weight
Everything starts with how much fabric one garment uses. Using the garment measurements (chest, length, sleeve length, and so on) you calculate the surface area, convert it to a piece weight using the GSM, and then add a wastage allowance for cutting and process loss. This gives the total fabric weight per piece, which is the foundation of the entire cost. If you want the detailed method, see our guide on how to calculate fabric consumption.
Step 2: Fabric cost
The piece weight is multiplied by the fabric rate, which itself is built from the yarn rate plus knitting, dyeing, and any washing or all-over-print processing. This is why two tees at the same GSM can cost very differently: the yarn count and the finishing route change the fabric rate. In most garments, fabric is the single largest line in the whole cost estimation.
Step 3: CMT cost (cutting, making, trimming)
CMT is the labour cost of turning fabric into a finished garment: cutting, stitching, and trimming. To calculate CMT cost you look at the operations a style needs and the time each takes, quoted per piece. A simple tee has a low CMT; a structured garment with many operations costs more. CMT is the part of garment costing that most reflects the complexity of your design.
Step 4: Trims and accessories
Every label, tag, and sticker adds up. Main and size labels, wash-care labels, hang tags, price stickers, and any hangers or packing accessories are totalled per piece. Individually small, together they are a real line on the cost sheet.
Step 5: Printing, elastic, and special processes
Any print, embroidery, woven badge, elastic, or special finish is added per piece. These are style-specific and can move the cost significantly on decorated garments.
Step 6: Overhead, margin, and landed cost
Finally, factory overhead and profit margin are applied to arrive at the unit price, and any commission or agent margin is added to reach the final buyer price. If a brand is importing, the landed cost then adds freight, duty, and clearing on top of the FOB price. This is the stage brands rarely see, but it is where a quote becomes sustainable or not.
A Worked Garment Costing Sheet (Sample)
Here is a simplified garment costing sheet for a basic cotton t-shirt, using illustrative numbers so you can follow the method. This is the structure behind clothing manufacturing cost estimation and the textile industry cost structure as a whole. Real rates vary by fabric, style, and order size, but the framework is exactly what a factory uses.
| Cost Component | How It Is Calculated | Example (USD) |
|---|---|---|
| Fabric | Piece weight (with wastage) × fabric rate | 2.80 |
| CMT | Cutting, making, trimming labour per piece | 1.20 |
| Trims & labels | Main, size, wash-care labels, tags, stickers | 0.40 |
| Printing | Per-piece cost of print or embroidery | 0.60 |
| Packing | Poly bag, carton share per piece | 0.30 |
| Factory cost | Sum of the above | 5.30 |
| Overhead & margin | Factory overhead + profit (varies) | applied on factory cost |
| Buyer price (FOB) | Factory cost + overhead + margin | illustrative final quote |
Numbers are illustrative. Actual rates depend on fabric, GSM, style complexity, order quantity, and finishing. This is the same structure we use for t-shirt costing and every other style.
Why this matters for your brand
A manufacturer who can show you a transparent garment cost breakdown, rather than a single take-it-or-leave-it number, is a manufacturer who will not surprise you later. When you understand where the cost sits, you can make better decisions on fabric, GSM, and decoration. To see how quality control fits alongside costing in a real order, read our guide on AQL inspection in the garment industry.
Frequently Asked Questions
What is costing in the garment industry?
Costing in the garment industry is the structured process of calculating the total cost to produce one garment, by adding up fabric, CMT labour, trims, printing, packing, overhead, and margin. It lets a manufacturer quote a price and a brand plan its margin.
What are the types of costing in the garment industry?
The main types of costing in the garment industry are cost sheet costing, marginal costing, standard costing, absorption costing, activity-based costing, job costing, process costing, and target costing. Most export quotations use cost sheet costing, a line-by-line build-up of every input.
Is there a garment costing formula?
There is no single formula. Garment costing is a build-up: fabric consumption times fabric rate, plus CMT, plus trims, plus printing and packing, gives the factory cost, and overhead plus margin gives the buyer price. The method matters more than any one formula.
How do you calculate CMT cost?
CMT cost is calculated from the cutting, making, and trimming operations a style requires and the time each takes, quoted per piece. Complex styles with more operations carry a higher CMT than a simple tee.
How do you make a garment costing sheet?
Start with fabric consumption and weight, multiply by the fabric rate for fabric cost, then add CMT, trims and labels, printing, and packing to reach the factory cost. Finally apply overhead and margin to arrive at the buyer price. That sequence is the garment costing sheet.
