2. Consumption & Costing
Fabric cost and fabric consumption are interrelated. Fabric cost is
defined as the amount of money is incurred per garment for the
fabric consumed in making garment. Fabric consumption can be
defined as the amount of fabric needed to make a garment. To
determine the cost of a garment after making the garment sample
consumption is needed.
Generally fabric consumption is calculated using following steps -
1. Pattern master develops patterns for the garment with seam
margin.
2. Garment patterns are then placed on the fabric laid flat on the
table as close as possible to each other.
3. Linear length of fabric that is covered by the patterns is
measured (for woven fabric). This measured length is the
consumption of the garment. Wastage percentage is added on it
to get average consumption.
3. Now-a-days most of the garment manufacturers use CAD systems
to determine fabric consumption.
To determine fabric cost for the garment, first fabric consumption
is calculated .
Secondly, merchant collects fabric quotes (prices) from fabric
suppliers. For woven fabric - fabric price is presented per meter or
yards and for knits price is presented per Kg.
After having fabric price list and average fabric consumption we
use following formula to determine fabric cost per garment.
Fabric cost per garment = Fabric consumption X Fabric price
Consumption & Costing
4. Before calculating the woven fabric consumption we need the
following information:
1. Measurement chart with technical specification
2. Style description
3. Fabric description
4. Fabric width
5. Washing shrinkage (if any)

10. Consumption Calculation (Manually):
Cpd = L x W x 12 yds
36x MW
Where, Cpd = Consumption per dozen
L = Length
W = Width
a) Cpd (Body)= L x W x 12 + Wastage %
36x56
= 29 x 20x 12 +3%
36x56
= 3.45+3 %
= 3.56 yds
11. b) Cpd( Sleeve)= L x W x 12 + Wastage %
36x56
= 13 x 18.5x 12 +3%
36x56
= 1.43 +3 %
= 1.47yds
c) Cpd ( Collar &
Collar stand) = L x W x 12 + Wastage %
36x56
= 16 x (4+5)x 12 +3%
36x56
= .86 +3 %
= .88 yds
12. d) Cpd(Pocket)= L x W x 12 + Wastage %
36x56
= 3.15 x 3x 12 +3%
36x56
= .057 +3 %
= .059 yds
Fabric Cpd = ( a+b+c+d)
= (3.56+1.47+.88+.059) yds
= 5.97 yds
If fabric shrinkage percantage is 3% & 3% then we have to add (4%+4% )
with the actual cpd to get the cpd.
Total Cpd = (5.97+8% ) = 6.45 yds
Fabric Consumption/pcs = 0.5373 yds
** By CAD system 0.540yds/pcs
24. Parameter Given (cm) Estimated (cm)
Waist 69 69+6=75
Hip 80 80+5=85
Thigh 50.5 50.5+5=55.5
Bottom 24.5 24.5+5=29.5
Length 104.5 104.5+5=109.5
Back pocket length 13.75 13.75+2=15.75
Back pocket width 13.5 13.5+2=15.5
25. Consumption Calculation: (Manually)
Marker width is 54”
a) As per formula the consumption (body) is as
follows:
=[{(75+85)/2}+{(55.5+29.5)/2}X109.5]X
(0.3937)2/(54*36) +3%
=1.1yds/pcs
b) Fabric Consumption for back pockets
= (15.75X15.5X2)X(0.3937)2 /(54X36)+3%
=0.04yds/pcs
26. Fabric consumption for leggings
= a+b
=1.1+.04
=1.14 yds/pcs
Total Fabric Consumption including shrinkage%
= (1.14+20% ) = 1.37 yds/pcs
** By CAD system 1.31 yds/pcs
