Formula:
Cpd     = L x W x 12 x GSM   kg
                     10000000
Where, Cpd = Consumption per dozen
            L     = Length
            W    = Width
A) Cpd (body) =  L x W x 12 x GSM    kg
                               10000000
                                    = 70 x 102x 12 x 150   kg
                                              10000000
                                    = 1.28 kg
B) Cpd (Sleeve)           =  L x W x 12 x  2 x  GSM  kg
                                                10000000
                                    = 25 x 49 x 12 x 2 x 150   kg
                                              10000000
                                    = 0.44 kg

C) Cpd (Neck)            =  L x W x 12 x GSM    kg
                              10000000
                                    = 61 x 7 x 12 x 180      kg
                                          10000000
                                    = 0.092 kg

So, total Cpd    = (A + B+C)
                                    = (1.28 + 0.44 + 0.09) kg
                                    = 1.81 kg
Actual Cpd                    = Total Cpd + 7% wastage
                                    = (1.81 + 7%)
                                    = 1.94 kg
So, the fabric consumption for men’s T-shirt is 1.94 kg per dozen.

                                               10000000
                                    = 1.28 kg


B) Cpd (Sleeve)           =  L x W x 12 x  2 x  GSM  kg
                                                  10000000

                                    = 25 x 49 x 12 x 2 x 150   kg
                                                     107
                                    = 0.44 kg
C) Cpd (Collar)            = L x W x 12 x GSM     kg
                                         107

                                                 107
                                    =  0.22 kg

C) Cpd (Collar)            = L x W x 12 x GSM     kg
                                                  107
                                    = 46 x 10 x 12 x 400    kg
                                                 107
                                    = 0.22 kg

D) Cpd (Cuff)  =  L x W x 12 x 2 x GSM  kg
                                                  107
                                    = 30 x 5 x 12 x 2 x 300            kg
                                                 107
                                    = 0.108 kg
So, total Cpd= A + B + C + D
                        = (1.28 + 0.44 + 0.22 + 0.108) kg
                        = 2.05kg

Actual Cpd       = 2.05 kg + 7%
                        = 2.19 kg
So, fabric consumption for 1 dozen polo shirt is 2.19 kg.

2. Accessories                                                  $2/dz                            $2/dz
3. CM (cost of manufacturing)                           $2/dz                          $2/dz    
                                                                                                                                   
                                                                                               Total                 $14

A) Direct cost (raw materials)                                              =   $14.0

B) Indirect cost (15% to 20% of direct cost)

     Indirect cost            = $14.0 x 20%

     Total                       = $14.0 + $2.8
                                     = $16.8
           
C) Profit @5% = $16.8 x 5%
                                    = @0.84
    Therefore, total cost  = $16.8 + $0.84
                                                = $17.64
