Posted on Jan 3, 2026 in Other subjects

Meaning of Material Control

Material control refers to the systematic planning, purchasing, storing, and utilization of materials to ensure that the right quantity and quality of materials are available at the right time, place, and cost. It aims to regulate the flow of materials from the point of purchase to the point of consumption so that production runs smoothly without interruptions or excessive investment in inventory. Material control is an essential component of cost accounting as it directly affects production cost, working capital, and overall operational efficiency.

Objectives of Material Control

An effective material control system focuses on achieving the following key objectives:

1. Ensuring Continuous Production

Maintains adequate stock levels to avoid production stoppages due to material shortages. This supports uninterrupted workflow and timely order fulfillment.

2. Minimizing Inventory Investment

Avoids excessive stock holding by determining optimum inventory levels. This helps reduce carrying cost, interest cost, and risk of obsolescence.

3. Reducing Wastage and Losses

Implements strict control mechanisms to prevent theft, pilferage, spoilage, leakage, and improper handling of materials.

4. Standardizing Material Quality

Ensures that purchased materials meet predetermined quality standards, thereby improving product quality and reducing rework or rejection.

5. Achieving Efficient Purchasing

Supports procurement at the most economical price, considering factors such as quantity discounts, supplier reliability, and delivery timelines.

6. Accurate Material Accounting

Maintains precise records of receipts, issues, and balances of materials to support cost accounting and financial reporting.

7. Improving Cost Control

Enhances management’s ability to monitor material usage, identify variances, and take corrective actions for cost savings.

Techniques of Material Control

Material control relies on several techniques and tools to maintain optimum stock levels, prevent wastage, and ensure operational efficiency. The key techniques include the following.

1. ABC Analysis

Classifies materials into three categories based on their consumption value:

• A items: High-value, low-quantity materials requiring strict control.
• B items: Moderate-value materials needing normal control.
• C items: Low-value, high-quantity materials requiring simple controls.

ABC analysis allocates managerial effort based on the economic importance of materials.

2. Economic Order Quantity (EOQ)

EOQ determines the optimal quantity of materials to be purchased at one time to minimize total inventory costs, including ordering and carrying costs. EOQ ensures a balance between stock levels and purchasing costs.

3. Perpetual Inventory System

Maintains continuous, real-time records of material receipts, issues, and balances. This system allows frequent stock verification and helps detect discrepancies early.

4. Bin Card and Store Ledger

• Bin card: Maintained by the storekeeper and records physical movement of materials.
• Store ledger: Maintained by the accounts department and records financial details of materials.

Both tools help reconcile physical and book inventory.

5. Setting Stock Levels

Involves establishing three control levels:

• Minimum Level: The lowest permissible quantity of stock.
• Maximum Level: The highest quantity to avoid excess investment.
• Reorder Level: The point at which new orders should be placed.

These levels ensure timely replenishment and prevent stockouts or overstocking.

6. Standardization and Simplification

Standardization ensures use of uniform specifications for materials, reducing variety and improving purchasing efficiency. Simplification minimizes the number of material types, reducing storage cost and handling complexity.

7. Material Requirement Planning (MRP)

MRP uses production schedules, lead times, and inventory data to estimate material needs. It helps reduce inventory levels and ensures materials arrive exactly when needed.

8. Vendor Management and Purchase Control

Includes supplier evaluation, negotiation, lead-time management, and quality checks to ensure materials are purchased economically and delivered reliably.

9. Regular Stock Verification

Periodic physical stock-taking and cycle counting help detect pilferage, errors, and discrepancies between physical and recorded stocks.

Methods of Pricing the Issue of Materials

Introduction

Pricing of material issues determines the cost assigned to materials when they are issued for production. The method selected influences product cost, profit, and inventory valuation. An efficient method should be simple, consistent, and aligned with organizational cost objectives.

1. FIFO (First-In, First-Out) Method

Materials purchased first are issued first.

Features:

• Ending inventory consists of latest prices.
• Suitable in rising prices to reduce profit manipulation.
• Matches historical cost flow with physical flow.

Advantages:

• Simple and logical.
• Prevents obsolescence.

Disadvantages:

• Cost of production may not reflect current prices.

2. LIFO (Last-In, First-Out) Method

Latest purchases are issued first.

Features:

• Ending inventory consists of oldest prices.
• Suitable in inflationary conditions.

Advantages:

• Better matching of cost with current revenue.

Disadvantages:

• Inventory valuation becomes outdated.
• Not accepted under many accounting standards.

3. Weighted Average Cost Method

Average price is computed by dividing total cost of materials by total quantity in stock.

Advantages:

• Smoothens price fluctuations.
• Simple and rational.

Disadvantages:

• Closing stock may not represent actual price movement.

4. Simple Average Cost Method

Average of prices of different lots, ignoring quantities. Used when prices fluctuate significantly.

5. Standard Price Method

Issues are priced at predetermined standard cost. Suitable for standard costing systems. Variances are analyzed regularly.

6. Replacement Price Method

Issues are valued at the price at which materials can currently be replaced.

Advantage: Reflects current cost.

Disadvantage: Volatile prices complicate calculations.

7. Market Price Method

Materials issued at prevailing market price regardless of purchase price.

8. HIFO and LOFO Methods

• HIFO: Highest price items issued first.
• LOFO: Lowest price items issued first.

Used rarely for special managerial decisions.

Conclusion

Material issue pricing methods impact cost computation, profit measurement, and inventory control. Organizations must choose methods that ensure consistency, reliability, and relevance to operational requirements.
