The term **Standard Minute Value – SMV** is mostly used in the garments industry. It is a process of time study and measure standard minute and then calculates the SMV. The calculation of SMV is actually done by the Industrial Engineer. Generally, SMV indicates the time taken to make garments by the workers using the right types of machinery. In the garments factory, you may find that many people used to the SAM – Standard Allowed Minute which is the same as SMV. SMV varies garments to garments, style to style, factory to factory. Management and buyers ask for SMV and it is the responsibility of the IE department to calculate SMV and give it to the respective parties. Here in this article, I will share details of Standard Minute Value: SMV in Garments, Calculation, Importance with a practical example.

**Standard Minute Value: SMV in Garments, Calculation, Importance**

Industrial Engineering is concerned with the design, improvement, and installation of an integrated system of men, machinery, and materials. SMV is one of the most important tools used by IE.

## The Main Objective of Industrial Engineering

- To Increase Productivity
- To eliminate waste and non-value added activities
- To come up with the optimum use of scarce resources that would bring out the best results.

**Importance of SMV in the Apparel Industry**

**The reason Why we use SMV in Garments Factory is given below**

- SMV is calculated for doing costing of garments
- It is used for calculation of target and set the right target
- For Calculating the Efficiency of workers
- SMV is calculated for making a plan and take effective factory production decisions.

**For Calculating SMV** – Standard Minute Value in Garments you must have a proper idea of machine operating procedure and working process of workers. Close observation of Industrial Engineer is required to calculate the right SMV for a particular product or style in your factory.

Basically, SMV is the sum of the basic time requirement and allowance applicable to it. Normally allowance is given at the rate of 10% based on efficiency.

**Formulas of Calculating SMV**

**Calculation of SMV in Garments**

**SMV** = (Basic Time + Allocated Allowance)

**The formula of Basic Time** = Observe Time x Rating Factor

**Basic Time**

Basic time is the most likely time required to make garments considering observe time and applicable rating factors.

**Observe Time**

Time is taken to do work when an observer is observing closely and record the worker’s work speed.

**Calculation of Observe Time** = Total Cycle Time is divided by Number of Cycle

**Cycle Time**

Cycle Time is the time between starting a garment manufacturing and finishing of those garments.

**Rating Factor**

The rating factor is assigned based on an evaluation of worker performance which is conducted through eye judgment. A worker can be fast, slow and rating is on a scale of 100% to lower.

Costing SMV is calculated for sending SMV information to buyers. Normally 5% additional time is added with the actual SMV.

**Costing SMV** = Actual SMV + (Actual SMV x 5%)

### Example of Calculation of SMV in Garments

Suppose for making a product the following assumption is there

- Observe Time = 25 Minutes
- Rating of Operator = 80%
- Considering Allowance = 10%
- Basic Time = 25minutes x 80% = 20 minutes
- Allowance = 20 x 10% = 2 Minute

So, SMV = 20 minutes + 2 minutes = 22 minutes for making a particular garments product

### SMV Calculator

You can use the following calculator to quickly calculate the SMV of garments.

### Calculation of Capacity of Single Operator in Garments

- If an operator works for 10 hours a day
- 30 minutes to make a product

Capacity = (1 operator x 10 hours x 60 minutes)/30 Minutes = 20 Pieces of Garments by an operator

If you assign 100 operators then your capacity will be = 100 operators x 20 pieces = 2000 pieces a day

**Calculation of Efficiency Percent**

- SMV 22 Minutes
- Working Hours 10 a Day
- Number of Operators 100 person
- Actual Production 2000 pieces

Efficiency (%) = (2000 pieces x 22 minute)/(100 operators x 10 hours x 60 minutes) x 100 = 73.33%

whereas,

Target = (10 hours x 60 minutes x 100 operators)/smv 22 minutes = 2727 Pieces of garments

### SMV of Different Garments Manufacturing

- SMV of Men’s Long Sleeve Shirt is 23.15
- SMV of 5 Pockets Long Pant is 20.14
- SMV of T-Shirt is 8.41
- SMV of Cargo Pant is 36.28
- SMV of Polo Shirt is 10.39
- SMV of Trouser is 8.13
- SMV of Chino Short Pant is 37.42
- SMV of Cargo Short Pant with Bone Pocket is 31.92
- SMV of Cargo Short Pant without Bone Pocket is 24.06
- SMV of Cargo Crop Pant is 30.74
- SMV of Men’s Chino Pant is 24.15
- SMV of Nano Chino Pant is 28.93
- SMV of Leggings is 4.64

- SMV of Kids Overall Hoodie is 21.60
- SMV of Brooke Short Pant is 9.32
- SMV of Brooke Skirt is 7.90
- SMV of Brooke Hoodies is 15.66
- SMV of Cody is 28.14
- SMV of Chino Pant is 36.86
- SMV of Blazer is 21.85
- SMV of Shirt Manufacturing is 33.84
- SMV of Jacket Manufacturing is 44.97

Nice and Good Cool

It is very important, thank you.

You’re the best of best.

Awesome.

Nice to know SMV- good work/thanks

Thanks

excellent work

VERY INFORMATIVE,GOOD WORK ALSO

Good article, the smv for trousers looks a bit low.

thanks for your valuable feedback

I work in the field of production in Romania

How can we cooperate in the field of Operation Breakdown, SMV and Layout
