5.1 Process Costing System Overview
3 min read•july 25, 2024
is a method for assigning costs to mass-produced, identical products. It's used in industries like oil refining and food processing, where large quantities of uniform goods are made continuously. This system averages costs over total units, focusing on departments rather than individual jobs.
Process costing differs from in key ways. It's ideal for standardized, high-volume production, while job order suits custom products. Process costing uses department-wide reports and calculates average costs, whereas job order tracks specific job costs on individual sheets.

- Process costing assigns costs to identical or similar units of product manufactured in large quantities through flow
- Averages costs over total units produced minimizing need for detailed individual unit tracking
- Accumulates costs by department or process stage rather than by specific jobs or orders
- Calculates per-unit costs by dividing total departmental costs by total equivalent units produced
- Focuses on processes or departments as cost objects instead of individual jobs or batches
- Suits industries with standardized high-volume production of homogeneous goods (oil refining, food processing)
Process costing vs job order costing
- Job order costing tracks costs for unique customized products while process costing accumulates costs for homogeneous mass-produced items
- Job order uses individual job cost sheets but process costing employs departmental production cost reports
- Job order calculates product costs specific to each job whereas process costing determines average across all units in a period
- Job order assigns costs as jobs finish while process costing allocates costs at period end
- Job order suits diverse product lines (custom furniture) but process costing fits standardized production (paper manufacturing)
Applications of process costing
- Oil refining and petrochemicals produce large volumes of standardized fuels and chemicals
- Food and beverage companies mass produce identical consumer goods (soft drinks, snack foods)
- Textile manufacturers create bulk quantities of uniform fabrics and garments
- Paper mills generate massive amounts of indistinguishable paper products
- Cement plants produce vast quantities of standardized construction materials
- Pharmaceutical companies manufacture large batches of identical medications and drugs
- Ideal for high-volume continuous production of goods indistinguishable from each other
- Useful when individual unit cost tracking impractical or unnecessary due to product uniformity
Cost flow in process costing
- added at process start or throughout, costs assigned to relevant department
- Direct labor applied continuously, costs accumulated by department based on hours or wages
- Manufacturing overhead allocated using predetermined rates (utilities, depreciation)
- Work in process inventory represents partially completed units, costs tracked by department
- Completed units and associated costs transfer between departments as production progresses
- Finished goods inventory accumulates costs of fully completed units from final department
- Cost of goods sold represents production costs of units sold to customers
- process:
- Accumulate costs by department
- Calculate
- Determine cost per equivalent unit
- Assign costs to completed units and ending WIP
- Transfer costs to next department or finished goods
Key Terms to Review (15)
Continuous production: Continuous production is a manufacturing process where goods are produced without interruption, often involving a steady flow of raw materials through a series of processes to create finished products. This method allows for high efficiency and consistency, making it ideal for large-scale production environments such as chemical plants, oil refineries, and food processing facilities.
Conversion Costs: Conversion costs are the expenses incurred in transforming raw materials into finished products. This term is crucial in understanding the manufacturing process as it combines direct labor costs and manufacturing overhead, highlighting the resources spent on converting materials into a sellable item.
Cost Allocation: Cost allocation is the process of distributing indirect costs to different cost objects such as products, departments, or projects. This process helps organizations determine the true cost of their operations and provides insights into profitability and efficiency.
Cost flow: Cost flow refers to the manner in which costs are accounted for and tracked as products move through different stages of production or service delivery. Understanding cost flow is essential for accurately determining inventory values and the cost of goods sold, impacting financial statements and overall profitability. It influences how costs are assigned to products and how financial results are reported, especially in manufacturing environments where multiple processes and departments are involved.
Cost of production report: A cost of production report is a detailed document that summarizes the costs incurred during a specific accounting period in a process costing system. It provides insights into the production process by outlining direct materials, direct labor, and manufacturing overhead costs, allowing businesses to analyze their efficiency and cost-effectiveness. This report is essential for tracking production costs and valuing inventory in industries where products are produced in a continuous flow.
Cost per Unit: Cost per unit is the total cost incurred to produce, store, and sell one unit of a product. This metric is crucial for understanding pricing strategies, profitability, and efficiency in production processes. It serves as a foundation for evaluating performance and making informed decisions about budgeting and cost management in various costing systems.
Direct Materials: Direct materials are the raw materials that can be directly traced to the production of specific goods or products. They play a crucial role in manufacturing as they form the essential components of finished goods, impacting cost flows, product classification, and overall manufacturing expenses.
Efficiency Ratio: The efficiency ratio is a financial metric used to assess how effectively a company utilizes its resources to generate income. It is calculated by dividing operating expenses by net revenues, which helps gauge the overall operational efficiency of a business. A lower efficiency ratio indicates better performance, as it signifies that a company is spending less on operations relative to the revenue it generates.
Equivalent Units of Production: Equivalent units of production represent the number of completed units that could have been produced given the amount of work done on partially completed units during a specific period. This concept is crucial in a process costing system because it allows for the accurate allocation of costs to both completed and in-process inventory, ensuring that financial statements reflect true production costs.
FIFO Method: The FIFO (First-In, First-Out) method is a cost accounting approach used to value inventory and determine cost of goods sold, where the oldest inventory costs are used first when products are sold. This method assumes that the earliest goods purchased or produced are the first ones to be sold, impacting both the financial statements and tax implications. The FIFO method is especially important in a process costing system, as it helps in calculating equivalent units and the cost per equivalent unit for production processes.
Job Order Costing: Job order costing is an accounting method used to assign costs to specific jobs or batches of products, allowing businesses to track expenses associated with each individual project. This method is particularly useful in industries where products are made to order, as it provides detailed cost information that helps managers evaluate profitability and efficiency. By contrasting job order costing with other methods, businesses can better manage costs and understand their financial performance across different projects.
Physical Units: Physical units refer to the tangible quantities of products that are produced in a manufacturing process, measured in terms of completed items or equivalent units of production. These units play a crucial role in determining the total costs incurred during production and are fundamental in process costing systems, where costs are allocated based on the physical output of goods.
Process Costing: Process costing is a method used to allocate costs to units of production by averaging the costs over all units produced during a specific time period. It is commonly used in industries where goods are produced in continuous processes, such as chemicals or food production. This system contrasts with job order costing, where costs are assigned to individual units or batches based on specific job requirements.
Standard Costing: Standard costing is a cost accounting method that assigns a predetermined cost to products or services, which serves as a benchmark for measuring performance and controlling costs. This approach allows businesses to compare actual costs with standard costs to identify variances and assess efficiency, facilitating better decision-making and financial control.
Weighted average method: The weighted average method is a technique used in process costing that calculates the cost of units by averaging costs based on the number of units produced, with a focus on the importance of each unit's contribution to total costs. This approach is essential for determining the cost of goods manufactured and helps businesses assign costs accurately to both completed and in-process inventory, ensuring a clear understanding of production expenses.
