Materials, Meaning, Objectives, Types and Importance
In cost accounting, materials refer to the physical inputs used in the production of goods or in providing services. Materials form a major part of prime cost and have a direct impact on the total cost of production. Proper control and management of materials are essential to reduce wastage, avoid shortages, and ensure smooth production.
Definition of Materials
Materials may be defined as:
“The commodities supplied to an undertaking for the purpose of consumption or conversion in the manufacturing process.”
Objectives of Material Control
- Ensuring Continuous Supply of Materials
One of the primary objectives of material control is to ensure a continuous and uninterrupted supply of materials for production. Proper planning, purchasing, and inventory management help avoid delays caused by material shortages. Continuous availability of materials prevents stoppage of work, idle labour, and underutilization of plant capacity. This objective ensures smooth production flow and timely completion of orders, thereby improving operational efficiency and customer satisfaction.
- Minimizing Material Cost
Material control aims to reduce the cost of materials without compromising quality. This is achieved through bulk purchasing, supplier negotiation, proper storage, and efficient usage of materials. Since material cost constitutes a major portion of total production cost, even a small reduction results in significant savings. Lower material cost directly contributes to increased profitability and competitive pricing in the market.
- Avoiding Overstocking and Understocking
Another important objective is to maintain optimum inventory levels. Overstocking leads to high carrying costs, risk of obsolescence, deterioration, and blockage of working capital. Understocking, on the other hand, causes production delays and loss of sales. Effective material control balances these two extremes by determining reorder levels, minimum levels, and economic order quantities.
- Reducing Wastage, Spoilage, and Losses
Material control seeks to minimize wastage, spoilage, pilferage, and leakage during storage and production. Proper handling, storage conditions, and issue procedures help prevent unnecessary losses. Reducing material wastage improves cost efficiency and ensures better utilization of resources. This objective is vital for maintaining accurate cost records and improving overall production economy.
- Maintaining Desired Quality of Materials
Ensuring the right quality of materials is a key objective of material control. Inferior quality materials result in defective production, increased rework, and customer dissatisfaction. Through proper supplier selection, inspection, and quality checks, material control ensures that only materials of required specifications are used. Good quality materials improve product reliability, reduce production losses, and enhance brand reputation.
- Effective Utilization of Working Capital
Material control helps in the efficient use of working capital by avoiding excessive investment in inventory. Since funds tied up in materials cannot be used elsewhere, proper inventory planning releases capital for other productive purposes. This objective improves liquidity, financial stability, and the overall financial health of the organization.
- Facilitating Accurate Costing and Pricing
Another objective of material control is to support accurate cost ascertainment. Proper recording of material purchases, issues, and balances helps in determining correct material cost per unit. Accurate material cost data is essential for preparing cost sheets, fixing selling prices, and submitting tenders or quotations. This objective strengthens managerial decision-making and pricing strategy.
- Supporting Efficient Production Planning and Control
Material control provides reliable information regarding material availability, consumption, and lead time, which supports effective production planning and scheduling. With proper material control, production managers can plan work efficiently and meet delivery schedules. This objective ensures coordination between purchase, stores, and production departments, resulting in improved operational performance.
Types of Materials
In cost accounting, materials are classified into different types based on their nature, usage, and traceability. Proper classification of materials helps in effective material control, accurate costing, and efficient inventory management.
1. Direct Materials
Direct materials are those materials that can be easily identified and directly traced to a specific product, job, or process.
These materials form an integral part of the finished product and constitute a major portion of prime cost. Examples include raw cotton in textile manufacturing, wood in furniture production, steel in automobile manufacturing, and flour in bakery products. Accurate control of direct materials is essential because they significantly influence total production cost and pricing decisions.
2. Indirect Materials
Indirect materials are materials that cannot be directly traced to a particular product or job and are used for general manufacturing purposes.
Examples include lubricants, cleaning materials, cotton waste, small tools, and spare parts. Indirect materials are treated as factory overheads and are apportioned to products using suitable bases. Though individually small in value, improper control of indirect materials can lead to significant cost escalation.
3. Raw Materials
Raw materials are basic materials that are converted into finished goods through the production process.
They may be direct or indirect in nature. Examples include iron ore for steel production, cotton for textiles, and timber for furniture. Efficient management of raw materials ensures uninterrupted production and reduces the risk of shortages or excess inventory.
4. Work-in-Progress Materials
Work-in-progress (WIP) materials refer to materials that are partially processed and are in different stages of completion.
These materials are neither raw materials nor finished goods. WIP materials include the cost of raw materials, labour, and overheads incurred till a particular stage of production. Proper control of WIP helps in accurate valuation of inventory and cost determination.
5. Finished Goods
Finished goods are completed products that are ready for sale to customers.
They include the total cost of materials, labour, and overheads incurred during production. Efficient control of finished goods inventory prevents overproduction, reduces storage costs, and ensures timely supply to the market.
6. Consumable Materials
Consumable materials are materials that are used up during production but do not form part of the finished product.
Examples include lubricants, fuels, oils, and cleaning supplies. These materials are generally classified as indirect materials and form part of overhead costs. Proper monitoring helps reduce wastage and unnecessary consumption.
7. Spare Parts and Stores
Spare parts and stores include items kept for maintenance and repair of machinery and equipment.
Examples include machine parts, tools, nuts, bolts, and bearings. Though not directly used in production, they are essential for smooth functioning of operations. Effective control avoids production breakdowns and excess investment in inventory.
Importance of Materials
Materials occupy a vital position in cost accounting because they constitute a major portion of total production cost. Efficient management and control of materials directly influence cost reduction, profitability, and smooth production. The importance of materials can be explained as follows:
- Major Component of Production Cost
Materials generally account for 50% to 70% of the total cost of production in manufacturing industries. Even a small saving in material cost can result in a significant increase in profit. Hence, proper planning, purchasing, storage, and usage of materials are essential to control overall production cost.
- Ensures Smooth and Continuous Production
Availability of materials at the right time ensures uninterrupted production. Shortage of materials can lead to stoppage of work, idle labour, and underutilization of machinery. Proper material management ensures continuous flow of production and timely completion of orders.
- Helps in Cost Control and Reduction
Effective control over materials helps in reducing wastage, spoilage, pilferage, and leakage. Techniques such as material control, inventory management, and proper issue procedures help minimize unnecessary losses. Reduced material wastage directly contributes to lower production cost and improved efficiency.
- Supports Accurate Costing and Pricing
Accurate recording of material purchases, issues, and balances helps in correct cost ascertainment. Proper material cost data is essential for preparing cost sheets, fixing selling prices, and submitting tenders or quotations. Without accurate material costing, pricing decisions may become unreliable.
- Improves Utilization of Working Capital
Materials involve a large investment of working capital. Overstocking blocks funds, while understocking disrupts production. Efficient material management ensures optimum inventory levels, thereby improving liquidity and effective utilization of working capital.
- Maintains Quality of Finished Products
Quality of finished goods largely depends on the quality of materials used. Use of inferior materials results in defective production, increased rework, and customer dissatisfaction. Proper material selection and inspection help maintain product quality and enhance customer goodwill.
- Facilitates Production Planning and Control
Material availability data helps management in production planning, scheduling, and control. Proper coordination between purchase, stores, and production departments ensures efficient workflow and timely delivery of goods. This improves overall operational performance.
