How To Calculate Beginning & Ending Inventory Costs

ending work in process inventory formula

However, companies will also carry over some WIP inventories from one process to another. Work-in-progress inventories include goods that are still in the production process at the reporting date. These inventories exist for companies that have a continuous production process or one which has various steps. When a company reports its inventories in the financial statements, they may still be under production.

This differentiation may not necessarily be the norm, so either term can be used to refer to unfinished products in most situations. This inventory is found on a manufacturing company’s balance sheet. This account of inventory, like the work-in-progress, may include direct labor, material, and manufacturing overhead. Production costs include raw materials, labor used in making goods, and allocated overhead.

This enables production managers to calibrate the output of their assembly line with market vagaries. Thus, managers can tamp down or increase production based on the availability of materials in bins on the factory floor.

This straightforward explanation of WIP inventory includes a step-by-step formula and explanation of the place of WIP inventory in the end-to-end supply chain. And, finally, once the WIP inventory becomes finished goods, the $5,000 is debited to the finished good account and $5,000 is credited back to the WIP inventory account. In our next section, we will do a comparison and reconciliation of the same number of products through one process with each of the two methods. Figure 4.3 “Concept of Equivalent Units” provides an example of the equivalent unit concept in which four desks, 50 percent complete, are the equivalent of two completed desks. Total WIP Costs are calculated as a sum of WIP Inventory + Direct Labor Costs + Overhead costs. He has experience working with retailers in various industries including sporting goods, automotive parts, outdoor equipment, and more.

Weighted Average

It is important to note that the methods of calculating ending inventory can only be used for estimating the inventory. A physical count or a cycle counting program is needed for an accurate ending inventory valuation. Partially completed inventory is known as work in process is inventory. This inventory requires additional processing before it can be classified as finished goods inventory. An item is considered both an inventory and a supply when the item can be sold to become an inventory or when the item is applied to generate new commodities and products. It refers to the costs of completing each stage of a long-term project, such as a construction job, so that clients can be billed gradually for completed milestones.

  • The work in process category is usually the smallest of the three most common inventory accounts, which also includes raw materials inventory and finished goods inventory.
  • The most obvious is that the items are in the process of being produced.
  • Cost accounting is a form of managerial accounting that aims to capture a company’s total cost of production by assessing its variable and fixed costs.
  • Work in process inventory refers to materials that are waiting to be assembled and sold.
  • Another reason to classify WIP inventory is that it’s a significant factor in the valuation of your business.

And each subsequent sub-process throughout the factory adds additional value. The difference between WIP and finished goods is based on the inventory’s stage of relative completion, which, in this instance, means saleability. Finished goods refer to the final stage of inventory, in which the product has reached a level of completion where the subsequent stage is the sale to a customer.

Why Is It Important To Classify Work In Progress Inventory?

So for the purposes of accounting, WIP inventory is the total value of any unfinished goods, and although they can’t be sold, these goods are counted as an asset on a balance sheet. It’s important to include WIP inventory as an asset when calculating the value of your business for finding investors or securing financing. On the accounting side, calculating WIP inventory is also important for understanding the true value of your inventory for tax purposes. There are things it doesn’t consider, like waste, spoilage, downtime, scrap, and MRO inventory. It would require combing through the production process and itemizing every little inevitability.

Usually, it includes the cost of raw materials, direct labor, and manufacturing overheads. When it comes to accounting for work in process inventory, WIP is considered a current asset, and is therefore combined with the inventory line item on the balance sheet. The work in process category is usually the smallest of the three most common inventory accounts, which also includes raw materials inventory and finished goods inventory. Cost of Goods Manufactured is a term used in managerial accounting that refers to a schedule or statement that shows the total production costs for a company during a specific period of time. Just like the name implies, COGM is the total cost incurred to manufacture products and transfer them into finished goods inventory for retail sale. Work-in-progress, as mentioned above, is sometimes used to refer toassetsthat require a considerable amount of time to complete, such as consulting or construction projects.

Why Does Work In Process Inventory Exist?

WIP inventories aren’t in the raw form, yet they aren’t finished goods either. In supply-chain management, work-in-progress refers to goods that are partially completed.

The restaurant may also have capital costs like monthly rent payments for its premises and maintenance on equipment used to make food. These two figures are necessary to create an income statement of a company, and sometimes they even appear on income statements.

Work In Process Vs Work In Progress Inventory

Raw materials, work in progress, and final goods are all included on a broad level. The ending Inventory formula calculates the value of goods available for sale at the end of the accounting period. Usually, it is recorded on the balance sheet at a lower cost or its market value. WIP inventory also helps in planning the production process and purchasing raw materials. Most companies generally lean towards the LIFO method to value their in-process inventory as it represents the current market value of goods used in production.

  • Accounting PeriodAccounting Period refers to the period in which all financial transactions are recorded and financial statements are prepared.
  • This applies to your business if you receive a product that must be assembled from separate parts, customize products to order, and more.
  • An item is considered both an inventory and a supply when the item can be sold to become an inventory or when the item is applied to generate new commodities and products.
  • Suppose you understand your WIP inventory and the impact it has on your business.
  • Overhead costs include things such as insurance, depreciation, and utilities.

This can be a bit time-consuming, so it’s typically best to tally it up at the end of your accounting period to minimize uncertainty on your company’s balance sheet. Work in process inventory is the stage immediately before it becomes a finished good. They aren’t yet ready for sale and are still listed under the inventory asset account in a company’s balance sheet. The inputted value of work in process inventory is often not the final amount, as other costs for packaging, storage, and transportation are also added in later steps. The beginning WIP inventory cost refers to the assets section of the previous accounting period on the balance sheet. To calculate beginning WIP inventory, determine the ending WIP’s inventory from the prior period and bring it over as the beginning figure of the new financial period. Every manufacturing company follows three primary phases in the manufacturing process.

Manufacturing Costs

Work-in-progress inventories include items that need a lengthy process to reach the finished goods stage. However, the usage of both terms may differ from one company to another.

  • Since manufacturing is a dynamic process of multiple constantly-moving parts, it is difficult to accurately calculate and account for WIP costs for each product.
  • Regardless of the type of company, all companies must produce the most accurate WIP count possible because, for taxation purposes, WIP is considered a current asset.
  • Deploying the ideal number of workers can help manage WIP inventory costs by optimizing your facility even without scaling the inventory itself.
  • Knowing how to properly calculate your work in process inventory can impact your balance sheet in a big way.

This total WIP figure is the ending work in process inventory for that accounting period—and the beginning work in process inventory for the next accounting period. During this period, the manufacturer spends $50 to purchase raw materials. Also, it spends $125 on employee salaries and $65 on rent and utilities. Meanwhile, work in process inventory at the beginning of the period is $10. In calculating profit, management requires not only revenue data but also production costs. Assuming revenue does not change, the firm can increase profit by streamlining production, resulting in lower costs. For example, Just-In-Time manufacturing practices emphasize the importance of keeping inventory levels to low figures or zero to ensure efficiency.


Regardless of the type of company, all companies must produce the most accurate WIP count possible because, for taxation purposes, WIP is considered a current asset. Current assets are any items that could be converted into cash in less than a year, which includes WIP. Current assets are then listed with all other assets on the “Operating Activities” part of the cash flow statement. Over that period of time, there will be multiple processes that the products will go through, and a cost will be added to each process which will then be added together to get one total cost. This cost will then be divided by the total number of products produced within that period, which will give out an average cost per unit. The formula enables one to track WIP inventory, unfinished goods, and production inventory with ease to accurate accounting.

In accounting applications, some businesses choose to reduce or eliminate work-in-progress inventory before the end of each accounting cycle. This can simplify the accounting process because doing so labels work in progress inventory as either completed products or raw materials. A work in process, though, generally takes the same amount of time and follows the same steps in the manufacturing process during each accounting period.

This covers everything from the overhead costs to the raw materials that come together to form the end product at a given stage in the production cycle. In accounting, WIP is considered a current asset and is categorized as a type of inventory. The cost of goods produced is the value that represents only the amount a company has spent to produce inventory that completes the entire work in process inventory manufacturing process and enters the market. Since these products are finished and ready for sale, they’re not accounted for in the work in process. This work in process formula yields an estimate, rather than an exact figure. It does not take into account added costs that may be incurred as work is completed, such as the cost of scrap, spoilage or the need to rework some items.
