Material Costs
Material costs refer to the expenses associated with the raw materials,
components, or supplies that are used in the production of goods or services.
These costs are crucial in determining the overall cost of production and are a
significant part of the cost structure in manufacturing or service businesses.
Material costs are typically divided into direct materials and indirect materials,
based on their relationship to the product being made.
1. Classification of Material Costs
a. Direct Materials
• Definition: Direct materials are raw materials that can be directly traced
to a specific product, job, or service. These are the primary inputs that
become an integral part of the finished product.
• Characteristics:
o Directly measurable and traceable to a cost object (product or
job).
o The cost of these materials is included in the total cost of
producing a product.
• Examples:
o In a furniture factory, wood, nails, and paint used in the
production of a table are direct materials.
o For a car manufacturing company, steel, tires, and engine
components are direct materials.
b. Indirect Materials
• Definition: Indirect materials are materials used in the production
process but are not directly traceable to a specific product or cost
object. These materials support the production process but do not form
a significant part of the finished product.
• Characteristics:
, o Used for general production purposes but cannot be directly
allocated to a specific product.
o Typically included in the manufacturing overhead.
• Examples:
o Lubricants, cleaning supplies, and small tools used in a factory.
o Glue, thread, or adhesives used in garment manufacturing, where
they are consumed but do not form a large part of the finished
product.
c. Semi-Direct Materials
• Definition: These materials have characteristics of both direct and
indirect materials. They can be directly associated with a product, but
due to their relatively low value or minor role in the final product, they
are treated as part of the overhead.
• Examples:
o Small screws, nails, or bolts that are used in manufacturing but are
difficult to trace in exact quantities per product.
2. Components of Material Costs
Material costs include both material purchase costs and inventory costs, which
together affect the overall cost of materials used in production.
a. Purchase Costs
• Definition: The purchase cost is the price paid to acquire raw materials.
This includes the base price of the materials, as well as any associated
costs like transportation, import duties, and taxes.
• Examples:
o A company buys steel from a supplier at $1,000 per ton. The
transportation cost is $200, and import duties are $100. The total
purchase cost would be $1,300.
b. Inventory Costs
, • Definition: Inventory costs are the costs associated with storing
materials before they are used in production. These include
warehousing, insurance, and handling costs.
• Examples:
o A company may pay $500 per month for warehouse space to store
materials before they are needed in the production process.
c. Wastage and Scrap
• Definition: Wastage refers to materials that are lost or damaged during
production, while scrap refers to leftover materials that cannot be used
in the current production process but may be sold or recycled.
• Examples:
o In a factory, some metal may be wasted during the cutting
process, or some fabric may be left over after garment
production.
o Scrap metal or plastic parts from manufacturing that can be sold
or reused.
3. Methods of Calculating Material Costs
a. Perpetual Inventory Method
• Definition: This method involves continuously updating inventory
records as materials are purchased and used in production. It ensures
that the quantity and cost of materials on hand are always known.
• Characteristics:
o Real-time tracking of material usage and stock levels.
o Often used in conjunction with inventory management systems
and software.
• Example: A company manufacturing electronics updates its records each
time components like resistors and transistors are bought or used in
production.
b. Periodic Inventory Method
, • Definition: In this method, material inventory is counted and valued at
regular intervals (e.g., monthly, quarterly) rather than continuously.
• Characteristics:
o Less frequent tracking compared to the perpetual system.
o Often used by small businesses or in industries where materials
are not consumed rapidly.
• Example: A small furniture manufacturer may check and adjust its
material inventory at the end of every quarter.
c. First In, First Out (FIFO) Method
• Definition: FIFO assumes that the first materials purchased are the first
ones used in production. This method values material usage by the cost
of the oldest materials in stock.
• Characteristics:
o Suitable for industries where materials have a limited shelf life or
are subject to changes in price.
o Commonly used for perishable goods or in industries with rising
material prices.
• Example: A bakery may use the FIFO method to account for flour and
other ingredients, ensuring that older stock is used first to prevent
waste.
d. Last In, First Out (LIFO) Method
• Definition: LIFO assumes that the last materials purchased are the first
ones used in production. This method uses the cost of the most recently
purchased materials to calculate the cost of goods sold.
• Characteristics:
o Often used in industries where material costs fluctuate
significantly over time.
o It can result in lower taxable income during periods of rising
prices.
