Carton Consumption, CBM & Price Calculation Method


Carton Costing is very important in supply chain and merchandising dept in garments industry. Basically, a simple formula can identify the carton consumption, CBM and cost.

Need below data first-

  1. Carton length in Centimeter. Example: 60 CM
  2. Carton width in Centimeter. Example: 40 CM
  3. Carton height in Centimeter. Example: 20 CM
  4. Allowance in Length: 6 CM (General rules)
  5. Allowance in Width: 4 CM (General rules)

 

Consumption:











Carton Price Per Pcs:

Suppose Price per square meter of carton is $0.85 (depending on market price).


= Carton consumption Per Pcs (square meter) × Rate (Per Square Meter)
= 1.1872 × $0.85
=$1.00912 per Pcs.

Now for 1pc carton costing stands at =$1.00912.

 

CBM (Cubic Centimeter):

It’s an important calculation for apparel merchandisers to identify CBM specially for vessel booking during shipment. Freight forwarder only works with CBM specially in sea shipment. Here is the formula-

 

Need below data first-

  1. Carton length in Centimeter. Example: 60 CM
  2. Carton width in Centimeter. Example: 40 CM
  3. Carton height in Centimeter. Example: 20 CM

 



 







If you have total 800 Cartons then total booking CBM will be .048 X 800 = 38.4 


Different types of samples in garments industry

 

Different types of samples used in garments industry-

 

 

  • Development Sample: Development samples are also called 1st sample to see design outlook as 1st impression. It can be changed after meeting.
  • Proto sample: Proto samples are mainly made to see garments workmanship. It can be asked by buyer for proto workmanship during development and bulk also.
  •  Fit sample: The main purpose of a Fit sample is to check fitting before making PP sample.
  •  Ad or photo-shoot sample: This sample is made for marketing purpose of sales. Customer pick this sample from bulk and initial stage also. Main purpose is to prepare advertising of the product.
  • Sales Man sample (SMS): This sample is also made for marketing purpose of sales. Customer ask this sample in development stage. Main purpose is to prepare a sales figure with several consumers during SMS Meeting. This sample is also called meeting sample.
  • Pre- production sample (PP Sample): This sample is made for checking all bulk parameter like, measurement, styling, print, Embroidery etc. This is the last stage before start sewing approved by buyer.
  • Size set sample: This sample is made for checking measurement, placement, fabric before start bulk cutting. With this sample buying QC conduct PP meeting with factory production concern.
  • TOP Sample: Pick up sample from bulk to send customer as shipment reference,
  • Wash sample: To check and get approval of wash shade, this samples are sent to customer from bulk wash dye lot.
  • Shipment sample: last sample to send customer as a shipment reference. This sample is similar like TOP sample. Upon customer approval, factory get shipment permission.

How to convert Yards from KGs in knit fabrics?

Converting yard from kg is very easy to calculate as below-

Suppose,       
       Fabric GSM   - 140
       Fabric width   -  45"
       Fabric Weight -  0.49181 kg

Rules:

Fabric length  =  Fabric weight / ( Fab width X Fab GSM /1550 / 1000)

Fabric length  =  0.49181 / ( 6300 / 1550 / 1000)

Fabric length  =  0.49181 / 0.00406451612

Fabric length  = 121" (where the fab width is 45" open)

Farbic length  = 3.3611 yards    (121/36")
