**Cost of Making of a Garment – Calculate CM: **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 which means $15.38 to $17.95/per day.

The above is for a non-compliance factory. For a compliance factory, the per day machine cost will be 1800 tk to 2100 tk ( $23.08 to $26.92).

**Example: **If an items produce 1600 pcs per day using 25 machines then what would be the CM cost ???

**Solution:**

CM cost = Overhead machine cost X require machine / produce quantity X 12

= (1800 X 25 / 1600 )X 12

= 337.5 Taka

= $ 337.5/78

= $ 4.32 /dozen

**Calculate the CM of a Garment **

Calculate the CM after discussion with your production department. It’s varies depends on require machine qty & output qty.

##### To find out the CM of an item you must need the following 06 (six) information at first, as listed below:

- The monthly total expenditure of your factory with factory rent, commercial cost, electricity bill, water bill, transportation, repairing, worker & staff wages, etc. (8hrs/day) in Bangla taka. Suppose-50,00,000/tk
- Qty of running Machine of your factory of the following month (which total expenditure we have considered here). Suppose- 100 machines.
- A number of machines to complete the layout for the following Items (which CM we are calculating). Suppose – 25 machines.
- Production target/capacity of the following items, per hour from the existing layout, excluding alter & reject. Suppose 200 pcs per hour.
- The total working day of the following month,(though the house rent, commercial expenses, machine overhauling & some other cost remain same)Suppose- 26 days.
- If you want to calculate the CM in US$ (dollar) then pls input the present dollar conversation rate BDTk. Suppose $1 = 78 tk.

**COST OF MAKING (CM) **

=(SAM of the garment * Minute costing of the labor) / Line efficiency (%)

OR,

= Overhead machine cost X require machine/produce quantity

= [{Monthly total expenditure of the following factory / (26 X Qty of running Machine of your factory of the following month)}] X (Number of machines to complete the layout) / produce quantity per day.

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

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

= (48,076.9 / 1600) X 12

= 30.048 X 12

= 360.58 Taka

= $ 360.58/ 78

= $ 4.62/dozen

This is the making cost (12 pcs) garments.

To make benefit from garments we have to calculate its cost of production before making the garments. So, here this article will help us to calculate. Thanks.

This is the ok

Thanks
