Find Accurate Work in Process Inventory with its Product Cost
In Manufacturing companies, we frequently hear about Work in Progress or in Process inventory. These are the semi Finished Goods that are to be assembled or Converted to Finished Goods after their next stage of activities. In the Factory, tracking of WIP Inventory is a nightmare and people use SKUs for the same.
What is Work in Process or in Progress?
Work in Process Inventory, often referred to as Work in Progress (WIP) Inventory, represents the goods or products that are currently in the production process but are not yet completed. In manufacturing, this includes materials, components, or assemblies that are undergoing various stages of production before they become finished products ready for sale. It is an essential concept in managing production operations and plays a crucial role in optimizing workflow and overall efficiency.
How to calculate Work in Process Inventory?
Calculating Work in Progress Inventory involves determining the value of the partially completed goods at a specific point in time. The formula for WIP Inventory calculation is:
WIP Inventory = (Cost of Materials and Labor for In-Progress Products) + (Manufacturing Overhead Allocated to In-Progress Products)
By summing up the cost of materials and labor used in the unfinished products and allocating the manufacturing overhead associated with these items, companies can ascertain the value of their Work in Process Inventory.
Why you need to monitor Work in Process Inventory in manufacturing?
Monitoring Work in Process Inventory is essential for several reasons:
Production Efficiency
Tracking WIP Inventory helps identify bottlenecks and inefficiencies in the production process, enabling manufacturers to address them promptly and optimize workflow.
Cost Control
By monitoring WIP Inventory, companies can manage their production costs more effectively, reducing waste and unnecessary expenses.
Timely Delivery
Keeping a close eye on WIP Inventory ensures that production schedules are met, enabling timely delivery of finished products to customers.
Resource Allocation
Monitoring WIP Inventory assists in better resource allocation, as companies can adjust their production capacities based on the level of work in progress.
Types of Work in Progress Inventory?
There are many types of Inventory in Manufacturing Shop Floor. It could range from Raw Materials to Semi Finished Goods to Finished goods. We also have Tools and consumables needed as part of Production reporting.
Raw Material Inventory
This type of WIP Inventory consists of raw materials and components that have been purchased but have not yet entered the production process. For example, a furniture manufacturer may have a stock of wood and fabric waiting to be processed.
Partially Completed Assemblies
WIP Inventory can also include partially completed assemblies or sub-assemblies. For instance, an automobile manufacturer may have partially assembled car frames awaiting further work.
Queued Inventory
This refers to goods that are in line for processing or awaiting their turn in the production line. For instance, in a bakery, trays of partially baked goods waiting to be finished represent queued inventory.
Testing and Quality Check Inventory
Products undergoing testing and quality checks before finalization are also considered WIP Inventory. An electronics manufacturer, for example, may have products going through quality control before being released to the market.
How does product costing impact by Work in Progress Inventory?
Product costing is a fundamental aspect of manufacturing, as it directly influences pricing decisions, profit margins, and overall financial performance. Work in Progress (WIP) Inventory plays a significant role in product costing, as it represents the partially completed goods at various stages of production. Understanding the impact of WIP Inventory on product costing is essential for manufacturers to accurately determine the cost of goods sold (COGS) and set competitive prices for their finished products.
Accurate Cost Allocation
Work in Progress Inventory contains the costs of materials, direct labor, and manufacturing overhead associated with products in the production process. These costs are incurred as the product advances through different stages of manufacturing. Properly allocating these costs to the WIP Inventory ensures that the final cost of the product reflects the resources invested in its production.
Example: ABC Manufacturing is producing custom-made furniture. As the production progresses, the cost of raw materials (wood, fabric, hardware) used, the labor hours spent on crafting the furniture, and the overhead costs (rent, utilities, etc.) incurred in the manufacturing facility are all accumulated in the WIP Inventory.
Impact on Cost of Goods Sold (COGS):
WIP Inventory has a direct impact on COGS, which is a crucial component in determining gross profit. The COGS is the total cost of all finished goods sold during a specific period. To calculate COGS accurately, the cost of goods completed during that period needs to be determined, and this includes the value of WIP Inventory that has been converted into finished goods.
Example: Suppose ABC Manufacturing completes 50 custom furniture pieces during a month, and each piece incurs $200 in production costs when finished. If the WIP Inventory at the beginning of the month was 20 furniture pieces, the total cost of goods completed during the month would be (50 pieces + 20 pieces) * $200 = $14,000.
Pricing Decisions
The cost of manufacturing, including the value of WIP Inventory, is a crucial factor in setting the price for finished products. Accurate product costing allows manufacturers to determine the minimum price they should charge to cover their production costs and maintain profitability.
Example: ABC Manufacturing must consider the total production costs, including WIP Inventory costs, when pricing their custom furniture pieces. If the total production cost of a piece of furniture is $400, the company might set the selling price at $600 to ensure a profit margin of $200 per unit.
Inventory Valuation
WIP Inventory also affects the valuation of the company’s inventory. As WIP Inventory represents the value of goods in progress, it is considered an asset in the company’s balance sheet.
Example: At the end of the financial year, ABC Manufacturing would include the value of its WIP Inventory in its total inventory valuation. This includes the materials, labor, and overhead costs invested in the products that have not yet been completed.
Cost Control and Process Improvement
Monitoring WIP Inventory costs allows manufacturers to identify areas of inefficiency in the production process and take corrective actions. By analyzing WIP costs, manufacturers can implement lean manufacturing practices and reduce waste, leading to better cost control and improved profitability.
Example: If ABC Manufacturing observes that the cost of materials in the WIP Inventory is high due to frequent material waste, they may adopt better inventory management practices or negotiate better deals with suppliers to reduce material costs.
Work in Progress Inventory has a significant impact on product costing, inventory valuation, and pricing decisions in manufacturing. Accurate cost allocation to WIP Inventory enables manufacturers to calculate COGS and set competitive prices for their finished products. Moreover, monitoring WIP Inventory costs aids in cost control and process improvement, leading to greater efficiency and profitability in the manufacturing process.
