work in process inventory formula

Equivalent units, used as denominator in calculating the weighted average cost, represent work done to date and not work done in the current period only. This is why it’s recommended that you only calculate WIP at the end of a specific reporting period, like the quarter, period, or year, to make things easier on yourself. You definitely need to find a happy medium when it comes to calculating WIP — you don’t want to do it too little, but you also don’t want to do it too frequently.

And each subsequent sub-process throughout the factory adds additional value. For accounting purposes, work in process is an asset, and therefore is aggregated into the inventory line item on the balance sheet. Work in process is usually the smallest of the 3 most common inventory accounts; the other two being raw materials and finished goods. WIP inventory also helps companies ensure the flow of production remains uninterrupted.

The amounts in raw materials, work in process, and finished goods inventories compose the total cost for each account, whereas the job cost sheets contain the costs for each individual job. On the other hand, WIP is an essential part of supply chain management that can help you identify potential problems in your production process. For example, if you consistently have high WIP values, this could potentially indicate a problem in the process, such as a bottleneck or another inefficiency. Thanks to your WIP calculations, you can clearly see this problem and take steps to solve it before it gets worse and ends up costing you money. 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.

Work in progress or work in process is a way of calculating the value of all the goods on your factory floor that are not quite finished. These goods are more valuable than raw materials because you’ve incurred some labor and overhead, but less valuable than finished goods that are ready for sale. As WIP will eventually convert to revenue, it’s an asset for the business. The value should only include raw materials, overhead, and direct labor spent so far. Projected costs for finishing the goods are not included as they will be listed under the “Expense” line of the next cash flow statement.

Work in Progress or Work in process is inventory that has begun the manufacturing process and not included in raw materials inventor… The value of the partially completed inventory is sometimes also called goods in process on the balance sheet.

How To Calculate The Ending Work

As a current asset, WIP is a taxable entity, and underestimating or inaccurate accounting can result in hefty fines. The opposite is also a danger as overestimating can make manufacturers responsible for higher taxes when they aren’t required. Effectively managing your inventory is one of the critical steps that one must take to run a successful business.

Typically, to calculate the amount of partially completed products in WIP, they are calculated as the percentage of the total overhead, labor, and material costs incurred by the company. A construction company, for work in process inventory formula example, may bill a company based on various stages of the project, where it may bill when it is 25% or 50% completed, and so forth. Production Impact – Inaccurate WIP accounting can also lead to production errors.

Whereas, Work in progress is a term used mainly in the construction business when a certain building is being constructed. You work with multiple suppliers to source materials then send them to a manufacturer to assemble your finished goods. You should also look into using a wholesale marketplace to find suppliers who can fill orders more quickly or even list your own products for sale. 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.

Since these products are finished and ready for sale, they’re not accounted for in the work in process. 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. 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.

  • Adam Hayes, Ph.D., CFA, is a financial writer with 15+ years Wall Street experience as a derivatives trader.

  • WIP and finished goods refer to the intermediary and final stages of an inventory life cycle, respectively.
  • WIP inventory figures are useful information to measure metrics related to the production process.
  • Ending WIP is listed on the company’s balance sheet along with amounts for raw materials and finished goods.

Minimizing WIP inventory before reporting it is both standard and necessary since it is difficult to estimate the percentage of completion for an inventory asset. Modern platforms not only allow tracking, accurate data and analysis, increased agility, and a high degree of customization. Taxation – No one wants to be audited by their country’s tax service for inaccurate taxes.

If you don’t have an ending inventory balance to include, simply subtract your cost of purchases.

In addition to this, COGM contributes to the overall clarity and planning of a company. It allows the company to plan and modify the pricing strategy for its products. It gives an accurate comparison of manufacturing operations from year to year. It will enable the planning of resource use and volume produced each period.

Which Is The Correct Formula For Beginning Inventory?

By using these practices and completing their backlog of WIP items, some companies regularly move all their WIP goods to the finished goods stage before accounting. Another essential use for the work-in-process formula is that it allows businesses and organizations to evaluate the performance and effectiveness of the manufacturing process. For instance, some manufacturing processes may not allow for zero values for work in process, and will signify slower productivity in the manufacturing process when these values are too high.

  • Work in progress sits in the middle of your manufacturing process between raw materials and finished product.
  • Typically, WIP is used in reference to the raw materials, direct labor costs, and factory overhead costs that are incurred for products at various stages of the production cycle.
  • Any business needs to adopt appropriate inventory management practices and ensure you have accurate WIP inventory values.
  • 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.
  • If the WIP calculation and valuation was wrong, the factory may become out of balance, impacting delivery schedules and leading to negative financial misfortunes from the reduction of future sales.
  • Another important factor in keeping WIP inventory low is accurate inventory cycle counts enabled by an integrated Warehouse Management System .
  • Work in process inventory is an important line item on a merchant’s balance sheet and a key indicator of the health of their supply chain.

But while larger companies can absorb a few more errors due to scale and averaging, small to medium-sized companies often have little to no room for error. There are three important reasons why accurate WIP accounting is a must. Suppose you understand your WIP inventory and the impact it has on your business. In that case, you can make informed supply chain management decisions and come up with innovative ways to optimize your supply chain and garner more revenue from it. The tracking of WIP inventory also helps determine or identify any challenges in the production process, thus enabling them to be resolved faster.

The work in process inventory refers to the part of the production cycle of turning your individual raw materials into a kettle. For the accounting period the cost of ending work in process is calculated. To the manufacturing costs is added to the beginning of work in process. An indication of how many times a company’s inventory of work-in-process materials move to completion and are replaced over a set period of time.


Most often used in construction, work-in-progress inventory calculates completion percentages, so clients are billed accordingly. It allows the company to earn a percentage at each stage until they earn their full amount. Taking the time to better understand WIP inventory can give you a deeper understanding of your supply chain management, which means better optimization and more revenue. The flow of WIP inventory is an indication of how efficient the manufacturer/supplier is at producing the finished goods. Working closely with a supplier and partners in a company’s retail supply chain can help optimize this supply chain. WIP inventory must be stored somewhere, and holding unsellable inventory for an extended period of time will increase inventory carry costs and drag down profitability.

These include raw materials as well as the cost of developing these materials into the final product, direct labour costs and factory overheads. 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. However, this is very time-intensive, and generally, it is not done. Often, this is the case when the manufacturing operation is short enough to allow all work in process to be completed when the period ends and current accounts are closed.

What Is The Cost Of Ending Work In Process Inventory?

You might end up either scaling down your production or ultimately overproducing. Further, a wrong WIP inventory is bound to influence key procurement decisions and sales and pricing strategies. High levels of WIP inventory also imply that you have many costs tied to the inventory account. This means that for as long as these funds are tied up in the WIP, you cannot apply them for other business needs or even invest them until the WIP has been completed and sold. WIP is calculated after a given period, either monthly, quarterly or annually. Typically, the ending WIP for a given accounting period automatically translates into the beginning WIP for the next period.

What Does Beginning Inventory Mean?

If the BOMs are correct for all WIP within a factory, the estimated number may be considered a close enough estimate for accounting. The valuing of WIP inventory tends to be a bit complex as one must understand precisely where the stock stands.
