﻿ Calculate the consumption of knit garments

### Calculate the consumption of knit garments

Consumption and costing is a primary requisite for a merchandiser. Fabric cost bears aprox 40% to 45% of the total cost of any garments so calculation of correct fabric consumption is very important.

Pls see below example of fabric consumption calculation

1. During the consumption pls used measurement of middle size for calculation or used the size which has most of the qty.

2. Except Cutting or sewing wastage, fabric wastage also depends on additional elements which. If the garments have special print, wash, embellishment etc than the fabric wastage will be more than normal wastage

 Description Msmnt (cm) Sewing Allowance Total Body Length 60 5 65 ½ Chest 45 2 47 Sleeve Length 20 5 25 Armhole Circum 40 2 42 Fabric Wastage 10% Depend on style and fabric GSM 140

Consider the measurement of middle size garment or the garment containing maximum quantity.

Consumption:

 Fabric Consumption Calculation of a Knit T-Shirt Length Width Consumption in SCM Back Part 65 cm ( length) x 47 cm ( Chest width) 65 47 3,055 scm Front Part 65 cm ( Front length) x 47 cm ( Front chest width) 65 47 3,055 scm Sleeve 25 cm ( Sleeve length) x 42 cm ( Armhole circumference) x 2 ( 2 sleeves) 25 42 2,100 scm Total Fabrics Consumption 8,210 scm/pc

Apply below formula to make consumption for 1dzn garments :

=(Fabric consumption in SCM X GSM X 12 / 10,000,000) + Wastage
=(8210 X 140 X 12 / 10,000,000) + 10%
=1.37928+10%
=1.37928+0.137928
=1.5172208 KG/DZN

or

 Description Consumption in SCM/pcs 9600 scm into sm. (10000 scm=1sm) 0.821 sm/pc Fabric is 140gsm, (1sm=140gram). So 0.821 sm=0.821x140= 114.94 gram/pc We know 1,000gram=1kg. So 114.94 gram=114.94/1,000= 0.1,149 kg/pc Wastage 10% 0.01149 kg Total Weight with wastage 0.12639 kg/pc Therefore, Weight of 1dzn (12 Pcs) 1.517 Kg/Dzn

Note:

scm=square centimeter
sm=square meter
1dozen (12pcs) garments
*Why 10,000,000?
10,000 x 1,000=10,000,000
Grams per square meter. Conversion of the fabric into square meter. 1m=100cm, 1sqr meter=10,000 cm (100cm x 100cm),
1 Kg=1,000 Gram.
