FABRIC COSTING:
The fabric costing is a very important aspect for any fabric manufacturer, merchandiser, textile exporter and Weaving technician. If a person knows, how to calculate the weaving cost of a fabric? He can finalize the order on the spot. An exporter can make a correct decision during purchase of fabric. A sourcing manager can get competitive price of fabric if he knows the method of fabric costing calculation.
There are following types of expenses occur in fabric manufacturing.
1- yarn cost.
2- Sizing cost.
3- Weaving cost.
1-Yarn cost:
We know that the fabric is made of warp and weft. Here the warp and weft weight is calculated separately. Before starting the fabric costing, we should know about fabric parameters. You should read my old blog on FABRIC PARAMETERS AND FABRIC ANALYSIS first to know about all details about fabric. The all fabric parameters are tested precisely in in-house or outside laboratory. Suppose that we receive following fabric parameters which are required to calculate the fabric cost:
1- EPI = 100
2- PPI = 80
3- Warp count = 40 s cotton
4- Weft count = 40 s cotton
5- Fabric width=120 inches
6- Warp crimp = 11 ℅
7- Weft crimp = 4℅
8- Waste percentage= 3℅
9- Warp yarn rate = Rs 250 per kg.
10- Weft yarn rate = Rs. 250 per kg
11 -Sizing cost = Rs. 20 per kg of warp
Warp weight:
It is determined by using following formula:
Weft weight:
It is calculated by using below formula:
Please not the yarn waste 3℅ is for rapier looms. It may be vary according to type of loom.
Sizing cost :
It is calculated by using following formula:
After finding of warp and weft weight, we can calculate the yarn cost only.
Sizing cost is the next step. Sizing cost has following factors:
1 – chemical cost
2 – power cost
3 – men power cost
4 – depreciation
5 - maintenance cost
Today sizing cost comes around RS. 20 per kg of warp for 40 s Ne yarn. It may be vary according to count. Sizing cost is low for coarse yarn and high for fine yarn.
We can calculate the sizing cost of warp of one meter of fabric by using following formula:
We can calculate the sizing cost of warp of one meter of fabric by using following formula:
Weaving cost :
Now we will discuss about weaving cost. Following factors are involved in weaving cost.
1. Power cost
2. Men power cost
3. Maintenance cost
4. Depreciation cost.
These costs are calculated for one meter of the fabric. Today’s weaving cost for this construction comes around Rs. 20 per meter.
When we find weaving cost per meter of fabric , we also calculate weaving cost per pick
What is this weaving cost per pick.
It is the cost incurring for one meter fabric when the picks per inch is 1.
It is calculated as below:

Now we have found all cost factors. The complete weaving cost sheet is given below :
