Knit Garments Costing and Consumption Calculation Method

Knit Garments (T-Shirt) Costing and Consumption in the Apparel Sector:

Fabric consumption and costing are one of the most important tasks for apparel merchandisers. To get a higher profit percentage from an apparel export order, a merchandiser should have calculated the total costing and consumption by applying accurate fabric consumption calculation formula. In this article, I have presented the total process of t-shirt costing and consumption calculation.

Knit Garments Costing (T-Shirt) and Consumption Calculation Method:

Calculate the price of a round neck T-shirt from the given measurement chart and apparel specifications:

Solution:

Fabric Consumption Calculation or Apparel Weight Calculation:
We have to follow the below formula during fabric consumption for the apparel in the textile and apparel sector.

Apparel weight calculation,

           [{T.L + S.L + (2× H.A) + (2 × S.A)} × (1/2 Chest + S.A)] × G.S.M × 2
= …………………………………………………………………………………        ………… (1)
                                                          10000

 And,
Round neck collar weight calculation,

           {(Neck round + S.A) × (Collar width + S.A) × G.S.M × 2}
= ……………………………………………………………………………     ………….. (2)
                                                     10000

Where,
T.L stands for Total length,
S.A stands for Seam allowance,
H.A stands for Hem allowance,
S.L stands for Sleeve length.

Apparel weight calculation for middle size i.e. L Size:

Let,
Seam allowance =1cm,
Hem allowance = 2cm,

So,
From equation-01, we get,

               {60+23+ (2×2) + (2×1)} × (50+1)] ×180×2
= ……………………………………………………………
                                     10000

= 166.60gms
= 0.167kg

Again,
From equation-02, we get,

           {(52+1) × (3+1) ×180×2}
= …………………………………………………..
                         10000

= 7.8gms
= 0.08kg

So,
L size apparel weight stands at,
= (0.167+0.08) kg
= 0.175kg

Fabric Cost Calculation Per Kg:

Fabric Cost Calculation Per Pc Apparel:

Fabric cost per apparel,
= (Apparel weight × Fabric cost per kg)
= (0.175 × Rs. 356.40)
= Rs. 62.37

Apparel Costing Format for T-Shirt:
The cost of the apparel is calculated as follows:
