Work in Process WIP Inventory Guide + Formula to Calculate

Superior Glass had to pay $2,500 in direct labor costs during the accounting period in order to produce March’s WIP. The direct labor costs that were incurred as a result of the WIP is credited to the wages payable account and debited to the WIP inventory account. Work-In-Process (WIP) refers to the materials that have started the production process, but have not yet been completed. The work-in-process inventory account is an asset account that is used to track the cost of the partially finished goods. Knowing how to accurately calculate WIP inventory can impact your balance sheet. This will give you a sense of COGS based on how much it costs to produce and manufacture finished goods.

How do you record work in process inventory?

  1. Determine the starting WIP inventory.
  2. Calculate the manufacturing costs.
  3. Find the cost of manufactured goods.
  4. Calculate the conclusive WIP inventory.
  5. Create a WIP journal entry.

Understanding WIP inventory can be challenging, especially since it consists of many moving parts during the production process. Here are some common questions that companies have on WIP inventory. Understanding WIP inventory can help you better understand supply chain management, so you can find ways to optimize your supply chain to drive more revenue. The work in process inventory formula is the Beginning WIP Inventory + Manufacturing Costs – COGM. Supply chain and managing all types of inventory are established fields of expertise now.

Example of a WIP Inventory Account

Further, production expediters may be used to force certain key jobs through the pile of work-in-process jobs, which throws the production system into an even greater muddle. Instead, work-in-process should move between work centers one unit at a time, with very little inventory piling up between workstations. Ideally, a lean production environment should contain so little work-in-process inventory that the amount on hand is immaterial. A piece of inventory is classified as a WIP whenever it has been mixed with human labor but has not reached final goods status. WIP, along with other inventory accounts, can be determined by various accounting methods across different companies.

Work in process (WIP) inventory is a term used to refer to partly finished materials within any production round. Work in process in production and supply chain management refers to the total cost of unfinished goods currently in production. The cost of purchasing a product factors into what it costs to make it (e.g., raw materials, labor, and production). Thus, your ending WIP inventory is essential to know for inventory accounting. The terms work-in-progress and finished goods are relative terms made in reference to the specific company accounting for its inventory.

Work in Process Inventory – What Is WIP and How To Calculate it?

All costs related to the WIP inventory, including the costs of raw materials, overhead costs, and labor costs, need to be considered for the balance sheet to be accurate. When combs are manufactured, plastic is moved into production as a raw material. Since the combs are only partially completed, all costs are posted to WIP.

  • If you can’t calculate your WIP, you won’t deserve that warehouse manager salary.
  • Doing this with spreadsheets or pen-and-paper is possible for very small or simple operations.
  • The WIP figure indicates your company has $60,000 worth of inventory that’s neither raw material nor finished goods—that’s your work in process inventory.
  • For example, if the painting department is behind schedule, the frames that are already painted can be moved to the assembly line so that they’re not sitting idle.

Let’s see if you’ve fundamentally understood what work in process inventory is. The most obvious is that the items are in the process of being produced. They may be on a conveyor belt in the act of fabrication or they may be waiting in a queue for further processing. Out of the three main types of inventory, WIP inventory is usually the most overlooked. But as you’re about to see, keeping tabs on this metric has big benefits. Now that you’ve got a grip on what WIP inventory is, you might be wondering why it’s important to classify in the first place.

Work-in-Process Inventory Account: Definition & Example

This means BlueCart Coffee Co. has $13,000 worth of inventory that’s neither raw material nor finished goods. For a perishable item like coffee, growing WIP inventory figures are a red flag unless they’re strategically kept as anticipation inventory. The WIP figure indicates your company has $60,000 worth of inventory that’s neither raw material nor finished goods—that’s your work in process inventory.

What is included in work in process inventory?

When the combs are completed, the costs are moved from WIP to finished goods, with both accounts being part of the inventory account. Costs are moved from inventory to cost of goods sold (COGS) when the combs are eventually sold. The WIP figure reflects only the value of those products in some intermediate production stages. This excludes the value of raw materials not yet incorporated into an item for sale. The WIP figure also excludes the value of finished products being held as inventory in anticipation of future sales. Any raw material inventory that has been combined with human labor but is not yet finished goods inventory is work in process inventory.

The cost of raw materials is the first cost incurred in this process because materials are required before any labor costs can be incurred. Work in process inventory encompasses all inventory types  in the intermediate stage between raw materials inventory and final products. If raw material is combined with direct labor but is not ready to be sold, it counts as WIP inventory. For example, if a company sells bags of coffee, their WIP inventory would include bags, labels, coffee beans, and shipping boxes.
