### Calculate the CM of a Garments.

Learn Apparel Merchandising, Learn Fashion design.
Dear All,
My this post for these people, who's are still confused regarding the CM (cost of making) of a knit items (garments). To find out the CM of a item you must need the following 06 (six) information at first, as listed below:

i. Monthly total expenditure of your factory with factory rent,commercial cost, electricity bill, water bill, transportation, repairing, worker & stuff wages etc. (8hrs/day) in bangla taka. Suppose - 50,00,000/- tk

ii. Qty of running Machine of your factory of the following month (which total expenditure we have consider here). Suppose - 100 machines

iii. Number of machine to complete the layout for the following Items (which CM we are calculating). Suppose - 25 machines

iv. Production target/capacity of the following items, per hour from the existing layout, excluding alter & reject. Suppose - 200 pcs per hour

v) Total working day of the followings month,(though the house rent,commercial expenses,machine overhauling & some other cost remain same)Suppose- 26 days.

v. If you want to calculate the CM in US\$ (dollar) then pls input present dollar conversation rate BDTk. Suppose - \$1 = 74 taka.

Now you should put the following information in the following form, which you will get here http://cmcostofaknitgarments.blogspot.com/

Otherwise you may follow the below rule:

COST OF MAKING (CM)

= {(Monthly total expenditure of the following factory / 26) / (Qty of running Machine of your factory of the following month) X (Number of machine to complete the layout)} / [{(Production capacity per hr from the existing layout,excluding alter & reject) X 8}] X 12 / (Dollar conversion rate)

= [{(50,00,000 / 26) / ( 100 ) X (25)} / {(200) X 8}] X 12 / 74

= [{192307.7 / (100) X (25) } / 1600] X 12 / 74

= (48,076.9 / 1600) X 12 / 74

= 30.048 X 12 / 74

= 360.58 / 74

= \$4.873 / dozen (this is the making cost (12 pcs) of the following items)

However, normally at present (after starting the new salary scale) in Bangladesh we calculate the CM of any item consider the overhead sewing machine cost 1200 tk to 1400 tk/day that means \$16.216 to \$18.92/per day.

Above is for a non-compliance factory. For the a compliance factory the per day machine cost will be 1800 tk to 2100 tk ( \$24.32 to \$28.37)

SO, if the an items produce 1600 pcs per day using 25 machines then the CM will be

= Overhead machine cost X require machine / produce quantity X 12 / \$74

= 1400 X 25 / 1600 X 12 / 74

= \$3.547/DOZ

19. Great great great

20. Bro pls make the correction

CM = [{(MTE / TWD) / (NRM / NML)} / (PCH x WHD)] x 12 / CR)}

21. (Qty of running Machine of your factory of the following month) X (Number of machine to complete the layout)} it should be
(Qty of running Machine of your factory of the following month) / (Number of machine to complete the layout)}
