Prime Cost (Meaning, Formula) | Calculation Examples

What is Prime Cost?

Prime cost is the direct cost incurred in the process of manufacturing a product and typically includes the direct production cost of goods including the raw material and direct labor costs. It is an essential part of total manufacturing expenses as costing and effective pricing of the goods are primarily determined on its basis.

It becomes a base for determining price including a margin for the product that is to be sold in the market.
It is a factor of direct cost which means the summation of all the expenses like direct cost, conversion cost and manufacturing cost those are directly incurred in the actual production of goods.
Any commission paid to a salesperson associated with particular sales is added in Prime Cost.
The raw material is an industry-specific component and it may vary according to the type of goods produced, like a car manufacturer company of an automobile industry require Tyre, glass, fiber, rubber, metal, nuts and bolts and many other small tools as raw material for manufacturing a car.
While direct labor is the same in all the industries and the wages paid to the workers who worked for manufacturing a car are also accumulated with the raw material cost to calculate Prime Cost of a car.
Any indirect cost like selling, administration, advertisements overhead is not a part of this Cost.

Prime Cost Formula

Prime Cost formula = Raw Material + Direct Labour

How to Calculate Prime Cost?

Example #1

A Hypothetical Car Manufacturing Company in India has incurred below expenditures in the year 2016-17 for manufacturing various cars-

To calculate Prime Cost we have to take figures of raw material consumption and direct cost paid to the workers. In the above example, suppose 3200 are paid towards direct labor cost out of entire direct expenditures;

Formula = Raw Material + Direct Labour = 7500 + 3200 = 10700 Crore

Please note – 1 Crore (cr) = 10 million

Example #2

Let us take another example to calculate the Price Cost.

Calculate the Prime Cost of a hypothetical furniture manufacturing company who incurred the following manufacturing expenses for the completion of one of its assignment;

5 Labour worked for 30 days
Labor charges are Rs 1000/- per labor per day
Wood – 100 sheets @ a cost of Rs 1500/- per sheet
Glue – 50 Kg @ a cost of Rs 250/- per Kg

Formula = Raw Material + Direct Labour

= (100*1500) + (50*250) + (1000*5*30)
= 150000 + 12500 + 150000
= Rs 312500/-

For an industry like furniture, wood and glue are treated as basic raw material and a skilled labor is required for making the customized furniture as per the customers need, without that furniture could not be produced and turned into finished goods.

Here 100 sheets of wood are used @ a cost of Rs 1500/- per sheet and 50Kg Glue used @ a cost of Rs 250/- per Kg. Then 5 works worked for 30 days at a cost of Rs 1000/- per worker per day hence we multiply all of these to calculate the amount of direct labor cost. The summation of all the costs is nothing but the Prime Cost.

Important Points to Note

We have taken only direct labor cost out of entire direct expenditure to calculate Prime Cost because various other costs may be involved in direct expenditure like carriage inward and freights. All other expenditures are part of indirect expenditure and neglected at the time of calculation of Prime Cost.

A direct labor cost is a part of both Prime Cost and Conversion Cost because Conversion Cost is a cost that is needed to convert a raw material into finished goods and it includes all the cost to convert the raw material into finished goods except the cost of raw material. Simply it includes direct labor cost and overall manufacturing overheads.
Production Department also uses this Cost as an important tool to effectively frame their costing budgets and implement the overall production process within the ambit of that budget. It also specifies the scope of improvement in the entire production line to reduce the cost of production by using economies of scales.
Management then analyses the market and determines the customers’ demand, paying capacity, competitors’ pricing and other strategies to enhance the supply of their products while offering the minimum selling price of the goods. They find break even selling price and set margins on the products and below that price manufacturing and selling of products would not be beneficial to the company.

6 Reasons that will Influence the Prime Cost

Followings are the few reasons:

#1 – Inflation

Inflation increases the cost as raw materials and director labors are more costly during the period of inflation. It is a macroeconomic factor and the entire economy would be affected by it and a single manufacturer could not be able to control it. In case of recession, the scenario will be reversed. Thus price escalation would be the main driving factor of this Cost.

#2 – Shortage of Supply

A short supply of raw material or unavailability of skilled labor may increase the cost of a specific product. It is an industry-specific measure and manufacturer of other products may not face the same problem.

#3 – Regulatory Actions

Changes in regulatory requirements are uncontrollable things and the entire industry can be affected by it. For Example, Government makes it mandatory for car manufacturing companies to add pollution control components in their cars. This Cost will increase by the amount of that specific pollution control component available in the market.

Considering the above-stated example of Car Manufacturing Company in India, if the company is required to spend Rs 850 Crore on that pollution control component, then Prime Cost for production of the car will be increased to Rs 11550 Crores in the year 2016-17.

Prime Cost Formula = Raw Material + Pollution Control Equipment + Direct Labour

= 7500 + 850 + 3200
= 11,550 Crores

Please note – 1 Crore (cr) = 10 million

#4 – Taxes

Applicable taxes to purchase a raw material will directly impact on the Prime Cost of the product. If the taxes and duties paid on the raw material rise then subsequent rise in Cost of the product will be reflected.

#5 – Technology

Technological changes directly affect the Prime Cost and companies are ready to adopt such changes to compete with the rivalry. Increase in the utilization of high technology machines, instead of direct labors in the production process, improves the entire production cycle in a more efficient manner along with the saving of time and cost of production.

#6 – Exchange Rates

Multinational manufacturing companies operate their businesses through various locations across the globe and they have to purchase the raw material from different destinations. In that case, foreign exchange rates of the importing countries could make a huge impact on the Prime Cost of the company.

For example, Laptop Manufacturing company in the United States which purchases the spare parts of laptop i.e. raw material from the Chinese company. If in case, the rates of Chinese Yuan increase against the US Dollar by 3%, the imported raw material would be more expensive in the hands of a laptop manufacturing company in the United States almost by 3%.
Hence this Cost for manufacturing a laptop would rise and laptop of the company gets expensive in the market by 3% or more. In such scenarios, the company may opt to purchase the raw material from other countries like Japan with whom currency rates might be stable to maintain the price of laptops in the market.

Conclusion

Prime Cost is the core production cost which includes direct raw material and direct labor cost. This is completely variable in nature as it’s a major component of Cost of Goods Sold. Being a direct manufacturing expense it is directly related to the number of sales. Unlike a fixed cost, it may be changed according to the production targets of the company.
