Introduction:
In garments trade, Consumption and Costing is the primary requisition
for a
merchandiser. Fabric cost bears approximately 40%-45% of the
total cost of any garments. So, calculation of correct fabric consumption is
very important to achieve the maximum profit from an order
Fabric consumption calculation method for woven shirt:
A garments merchandiser should identify each parts of a “woven long
sleeve shirt” before starting the consumption calculation-
Normally, a “woven long sleeve
shirt” consists with the following parts-
1. Body
parts (Body Length + Chest width),
2. Sleeve,
3. Collar,
4. Cuff,
5. Collar
Band,
6. Pocket,
7. Yoke.
Suppose,
The buyer “GAP” forwards a “woven long sleeve shirt” item order
(10000pcs) to you with the following specification.
Follow the below measurement chart.
Now, find the required fabric consumption for the order.
Solution:
Consumption method for the above order will be discussed in the
below in part by part.
Let,
Fabric width- 55”
Wastage-10%
1. Fabric consumption for the
Body Parts (Body + Chest):
Here, we will apply the following formula (Per dozen),
= {(Body Length from HSP + Allowance) ×
(1/2 Chest + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)
= {(76 × 56 × 2 × 12) / (55 × 36 × 2.54)
(In Yds.)
= 20.31yds per
dozen……………………………………………………………………….. (1)
So, consumption for the Body Parts (Body + Chest) is 20.31yds per
dozen.
(Note: 2.54 used to convert into inch from cm and 36
used to convert into yds from inch).
Clarification of formula:
**Why 36
Ans: To convert inch into yard. 36 inch=1yard
**Why 55
Ans: Fabric width 55 inch. It may vary.
**Why
2.54
Ans:
If Measurement is cm.
2. Fabric consumption for the
Sleeve:
Here, we will apply the following formula (Per dozen),
= {(Sleeve Length + Allowance) × (Arm
hole straight + Allowance) × 2 ×2×12} / (Fabric Width × 36 × 2.54)
= {(66 × 28 × 2 × 2 × 12) / (55 × 36 ×
2.54) (In Yds.)
= 17.64yds per dozen………………………………………………………………………… (2)
So, consumption for the sleeve is 17.64yds per dozen.
3. Fabric consumption for the
Collar:
Here, we will apply the following formula (Per dozen),
= {(Collar Length + Allowance) × (Collar
width + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)
= {(44 × 8 × 2 × 12) / (55 × 36 × 2.54)
(In Yds.)
= 1.68yds per dozen………………………………………………………………………………… (3)
So, consumption for the Collar is 1.68yds per dozen.
4. Fabric consumption for the
Cuff:
Here, we will apply the following formula (Per dozen),
= {(Cuff Length + Allowance) × (Cuff
width + Allowance) × 2 ×2×12} / (Fabric Width × 36 × 2.54)
= {(12 × 3 × 2 × 2 × 12) / (55 × 36 ×
2.54) (In Yds.)
= 0.344yds per dozen……………………………………………………………………………. (4)
So, consumption for the Cuff is 0.344yds per dozen.
5. Consumption for the Collar
Band:
Here, we will apply the following formula (Per dozen),
= {(Collar Band Length + Allowance) ×
(Collar Band width + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)
= {(33 × 4 × 2 × 12) / (55 × 36 × 2.54)
(In Yds.)
= 0.63yds per dozen…………………………………………………………………………….. (5)
So, consumption for the Collar Band is 0.63yds per dozen.
6. Consumption for the Pocket:
Here, we will apply the following formula (Per dozen),
= {(Pocket Length + Allowance) × (Pocket
width + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)
= {(14 × 11 × 2 × 12) / (55 × 36 × 2.54)
(In Yds.)
= 0.735yds per dozen………………………………………………………………………. (6)
So, fabric consumption for the Pocket is 0.735yds per dozen.
7. Consumption for the Yoke:
Here, we will apply the following formula (Per dozen),
= {(Yoke Length + Allowance) × (Yoke
Height + Allowance) ×2×12} / (Fabric Width × 36 × 2.54)
= {(49 × 13 × 2 × 12) / (55 × 36 × 2.54)
(In Yds.)
= 3.04yds per dozen………………………………………………………………………….. (7)
So, consumption for the Yoke is 3.04yds per dozen.
Now,
Total fabric consumption for the woven long sleeve shirt is-
= [{Number (1) + Number (2) + Number (3) + Number (4) + Number (5) +
Number (6) + Number (7)} + Wastage%]
= {(20.31 + 17.64 + 1.68 + 0.344 + 0.63 + 0.735 + 3.04) + 10%}
= (44.379 + 10%) per dozen.
= 48.82yds per dozen.
So, total fabric consumption for the woven long sleeve shirt is
48.82yds per dozen.
And,
Total fabric consumption for 10000pcs (833.33 dozen) woven long sleeve shirt is
(48.82 × 833.33) = 40680.59yds.

How to Calculate Garments Costing for Woven Bottom?
Introduction:
A garments business is totally stands on order profit. An order profit
can be achieved through a proper costing. A proper costing can be done by using
a proper garments costing method. So, ultimately, garments costing method is
the heart of
readymade garments business. To make an accurate costing
of an order, today I will discuss about the method of garments costing
for
woven bottom.
Method of Garments Costing for Woven Bottom (Factory Costing):
· Fabric
Cost,
· Printing
Cost,
· Commercial
Cost,
· Others
Cost.
Important tips***
· The very next duty of a woven garments merchandiser is to determine the fabric
consumption and costing.
· After
fabric consumption and costing, all the others necessary cost should be added
with fabric cost to achieve total cost of a garment.
To clear all the confusion about the above discussion, now I will
present an example for woven bottom costing in the below.
Example:
Suppose,
The Buyer “Metro-Tex” forwards a “Woven Denim Bottom” item order to you
with the following specification.
Follow the below measurement chart.

Now, determine the garments
costing (on FOB) for the above order.
Solution:
Fabric width – 58”
(Here, the given fabric width is 58”, during sewing, we cannot use the
edge of a fabric. So, all time we must exclude 1” from the given fabric width.
So, now the fabric width is 58-1 = 57”)
Wastage – 10%
Let,
1. Fabric
Cost per yds- $3.70
2. Printing
Cost per dozen- $1.40
3. Embroidery
Cost per dozen- $3.80
4. Accessories
Cost per dozen- $1.70
5. Washing
Cost per pcs- $2.00 so, washing cost per dozen is – ($2.00 × 12) = $24.00
Now, we have to calculate the
fabric consumption for the above order.
1. Fabric consumption for the
Body Parts:
Here, we will apply the following formula (Per dozen),
= (Body Length + Allowance × 1/2 Thigh width + Allowance × No. of Parts
× 12) / (Fabric width × 36) (In yds.)
= (48 × 22 × 4 × 12) / (57 × 36) (In yds.)
= 24.70yds per dozen………………………………………………… (A)
So, fabrics needed for the body parts is 24.70yds per dozen.
Note: Body Length = [(Front Rise + Back Rise) / 2] + Inseam Length
2. Fabric consumption for the Back Pocket (2pcs):
Here, we will apply the following formula (Per dozen),
= (Back Pocket Length + Allowance × Back Pocket width + Allowance × No.
of Parts × No. of Pocket × 12) / (Fabric width × 36) (In yds.)
= (9 × 8 × 2 × 2 × 12) / (57 × 36) (In yds.)
= 1.68yds per dozen……………………………………………………………….. (B)
So, fabrics needed for the back pocket is 1.68yds per dozen.
3. Fabric consumption for the
Pocket Bag (2pcs):
Here, we will apply the following formula (Per dozen),
= (Pocket Bag Length + Allowance × Pocket Bag width + Allowance × No.
of Parts × No. of Pocket × 12) / (Fabric width × 36) (In yds.)
= (9 × 8 × 4 × 2 × 12) / (57 × 36) (In yds.)
= 3.37yds per dozen……………………………………………… (C)
So, fabrics needed for the pocket bag is 3.37yds per dozen.
4. Fabric consumption for the
Belt Loop (5pcs):
Here, we will apply the following formula (Per dozen),
= (Belt Loop Length + Allowance × Belt Loop width + Allowance × No. of
Parts × No. of Belt Loop × 12) / (Fabric width × 36) (In yds.)
= (2 × 1 × 2 × 5 × 12) / (57 × 36) (In yds.)
= 0.12yds per dozen……………………………………………. (D)
So, fabrics needed for the belt loop is 0.12yds per dozen.
Now,
By adding the equation B, C, D and E we can achieve the total
fabrics consumption for the above order (per dozen)-
= (A +B +C + D) yds. Per dozen
= (24.70 + 1.68 + 3.37 + 0.12) yds. per dozen.
= 29.87yds per dozen.
So, total fabric consumption for the above order is 29.87yds per
dozen.
As, fabric cost per yds is $3.70 then, total fabric cost per dozen is
(29.87yds × $3.70) = $110.52
Now,
By adding all the following costs with total fabric cost, we will get
the total FOB cost of garments per dozen.
Fabric cost per dozen ………………………… $110.52 ……………………. (E)
Printing Cost per dozen ………………………$1.40 ……………….…...…… (F)
Embroidery Cost per dozen ………………… $3.80 …………………………. (G)
Accessories Cost per dozen …………………..$1.70 …………….…………… (H)
Washing cost per dozen ……………………… $24.00………………………… (I)
Cost of making (CM)…………………………… $5.00 …………..…………….. (J)
Commercial cost ………………………….……. $0.60 ………………………….. (K)
Others cost ………………………………….……. $0.20 ………………………….. (L)
So,
Total FOB cost per dozen = (G +H + I + J + K + L)
= $ (110.52 + 1.40 + 3.80 + 1.70 + 24.00 + 5.00 + 0.60 + 0.20)
= $147.22 per dozen.
In case of factory, we received the order from a buying hose (Here, we
got the order from Metro-Tex Buying House), so we have to pay 7%commission to
them for that order.
So, in this situation, total FOB cost per dozen stands at-
= $147.22 per dozen + 7% commission
= $157.53 per dozen.
In factory costing, profit% for the factory (here-10%) should be added
with total FOB cost per dozen.
So,
Total FOB cost per dozen with profit% stands at-
=$157.53 + 10% profit
= $173.28
Now, total FOB cost per pcs is ($173.28 / 12) = $14.44
So, factory cost (FOB) per pcs garment is $14.44
