**Introduction**

This article is going to talk about how to calculate dyeing cost in Textile Wet Processing Factory simple way. There are some factors that are involved when calculating dyeing cost in Textile Wet Processing Factory.

- Types of chemicals and dyes
- Types of fabric used and shade required.
- Types of dyeing machines and methods used.
- Lab expenditure incurred during shade development
- Effluent treatment cost.

In the following examples, you will find an initiative to estimate the cost of the pre-treatment and dyeing process. The data provided here are approximate and are being used only as a guide. This article is shown calculate dyeing cost for knitted fabric and woven fabric.

**Exercise: Calculate Dyeing Cost**

**Exercise 1:** A textile dyeing factory received an order from a garment manufacturer to dye a knitted fabric of 1000 kg. This company can dyeing 300 kg of fabric on a daily basis. The materials and prices used in the process are listed below in the table 1. If the company works one shift per day, calculate the dyeing cost per kilogram with a 20% profit. The total overhead for a month is Rs. 2,50,000 which includes salaries for other employees, electricity bills, plant rent, and other costs.

S/N | Items used | Quantity used | Price in Rs. |

1. | Reactive dye | 3 kg | 300 per kg |

2. | Reactive dye B | 6 kg | 250 per kg |

3. | Chemical XYZ | 8 kg | 80 per kg |

4. | Chemical ABC | 10 kg | 150 per kg |

5. | Machine operators used | 8 | 400 per shift |

6. | Machine helpers used | 4 | 200 per shift. |

**Solution**

**Step 1: Total shift calculation**

- The total production need to be done= 1000 kg
- Daily production of the company= 300 kg per shift
- The total shifts required= Order quantity ÷ daily production= 1000 ÷ 300= 3.33 shifts

**Step 2: Labour cost**

The number of labours used are, 8 machine operators with the wages of Rs. 400 per shift and 4 machine helper with the wage of Rs. 200 per shift.

- Labour cost of machine operator = number of labour× total working shifts × wage of per shift= 8× 3.33 × 400= 10,656
- Labour cost of machine helper= 4× 3.33 × 200= 2,664
- Total labour cost= machine operator cost+ helper cost= 10,656 + 2,664= Rs. 13,320

**Step: 3: calculation of chemical cost**

- Reactive dye= 3× 300= 900
- Reactive dye B= 6× 250= 1,500
- Chemical XYZ= 8× 80= 640
- Chemical ABC= 10× 150= 1500
- Total chemical cost= (900+1500+640+1500)= Rs. 4,540

**Step 4: Calculate overhead cost**

Company works for this order only 3.33 shifts. Hence, the overhead costs for 3.33 shifts are,

- Total overhead cost= Rs. 2,50,000
- Overhead per day ( 1 shift)= 2,50,000 ÷ 30= Rs.8,333.33
- Therefore, overhead cost for this order= 8,333.33 × 3.33= Rs. 27,749.99

**Step 5: Calculate dyeing cost per kg**

- Total cost= labour cost + chemical cost + overheads= 13,320+ 4,540+ 27,749.99= Rs. 45, 609.99
- Total cost with 20% profit= 45,609.99 + ( 20% profit of 45,609.99)= Rs. 54,731.99
- Total dyeing cost/ kg= 54,731.99 ÷ 1000= Rs. 54.73

**N.B.:** Based on their previous experience, companies/merchanters can estimate the cost of dyeing. The exact cost of dyeing must be calculated after the dyeing process has been completed, based on the chemicals and dyes consumed. For a particular order, the above example shows the total cost based on the consumption of all chemicals.

**Example 2:** An order from a garment manufacturer for the dyeing of 1,50,000 metres of woven fabric was received by a textile dyeing factory . The average production per shift in the company is 30,000 metres. The materials and prices used in the process are listed below table 2. If the company works one shift per day, calculate the dyeing cost per metre with 15% profit. A monthly overhead charge of Rs. 75,000 is incurred for steam, Rs. 30,000 for power, Rs. 7,000 for transport, Rs. 20,000 for rent, and Rs. 95,000 for other expenses.(Assume company works 26 days per month).

S/N | Items used | Quantity used | Price in Rs. |

1. | Dye A | 40 kg | 400 per kg |

2. | Chemical 1 | 70 kg | 200 per kg |

3. | Chemical 2 | 20 kg | 170 per kg |

4. | Chemical 3 | 60 kg | 150 per kg |

5. | Machine operators used | 15 | 400 per shift |

6. | Machine helpers used | 7 | 200 per shift. |

**Solution**

**Step 1: Total shift calculation**

- The total production need to be done= 1,50,000 metres
- Daily production of the company= 30,000 per shift
- The total shifts required= Order quantity ÷ daily production= 1,50,000÷ 30,000= 5 shifts

**Step 2: Labour cost**

The number of labours used are, 15 machine operators with the wages of Rs. 400 per shift and 7 machine helper with the wage of Rs. 200 per shift.

- Labour cost of machine operator = number of labour× total working shifts × wage of per shift= 15× 5× 400= Rs. 30,000
- Labour cost of machine helper= 7× 5 × 200= Rs. 7,000
- Total labour cost= machine operator cost+ helper cost= 30,000+7,000= Rs. 37,000

**Step: 3: Calculation of chemical cost.**

- Dye A= 40× 400= 16,000
- Chemical 1 = 70× 200= 14,000
- Chemical 2 = 20× 170= 3,400
- Chemical 3 = 60 × 150= 9,000
- Total chemical cost= (16,000+14,000+3,400+9,000)= Rs. 42,400

**Step 4: Calculation of overhead cost**

Company works for this order only 5 shifts. Hence, the overhead costs for 5 shifts are,

- Total overhead cost= (75,000+30,000+7,000+20,000+95,000)= Rs. 2,27,000 per 26 days
- Overhead per day ( 1 shift)= 2,27,000÷ 26= Rs. 8,730.77
- Therefore, overhead cost for this order= 8,730.77 × 5= Rs. 43,653.85

**Step 5: Calculate dyeing cost**

- Total cost= labour cost + chemical cost + overheads= 37,000+ 42,400+ 43,653.85= Rs. 1,23,053.85
- Total cost with 10% profit= 1,23,053.85 + ( 15% profit of 1,23,053.85)= Rs. 1,41,511.93
- Total dyeing cost/ kg= 1,41,511.93÷ 1,50,000= Rs. 0.94 per metre of fabric.
