Tracking WIP inventory accurately ensures better planning and reduces production bottlenecks. One of the advantages of calculating it manually is that you can add expenses like the cost of scrap, spoilage of raw material, etc. which are all visible during physical counting. Learn how Inventory management ensures the right stock balance to meet demand and maximize efficiency. It’s a good idea to calculate your WIP inventory on a regular basis, such as weekly or monthly.

Example 1: Calculation of WIP Inventory

To achieve this, WIP needs to be continuously managed and tracked throughout the manufacturing process. Designing optimized storage and shop floor layouts and considering WIP inventory volumes already in the production planning phase is also a must. In practice, advanced manufacturers find the COGM and ending WIP values based on real data from their production management system. The accountant can then compare the real-world data with the financial metrics to make sure everything checks out.

How the Balance Sheet Looks (Table Example)?

The ending work in process formula allows you to measure the effectiveness of your company’s manufacturing process. Some processes may not allow for a zero value for ending WIP, but values that are too high can signify slowdowns in the process. Since works in process cannot be sold, they also represent lost revenue opportunities. Now that you know what work in process inventory is and how it can benefit you, are you trying to find a way to smooth out the custom process? Customs are important, especially if your company is trying to get products from international companies. The regular audits can really help you understand the position of bookkeeping the WIP inventory.

WIP inventory represents goods still undergoing production or processing. These goods have incurred some costs but are not ready for sale or use. In contrast, finished goods inventory are goods that are ready for sale.

Comparing Work-in-Progress With Finished Goods

• This makes it easy to track your inventory quickly and accurately, reducing the risk of errors and improving overall efficiency.
• These products are neither raw materials nor finished goods but are still assets (with value attached) for the company.
• Direct materials are the raw materials that are directly used in the manufacturing process.
• See first-hand the ways manufacturing inventory software can help you maintain healthy cash flow and optimise production processes with a risk-free two-week trial of Unleashed.
• This system should allow you to track each component of your WIP inventory in real-time, giving you a clear picture of what’s available and what’s needed.
• 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.
• These goods have incurred some costs but are not ready for sale or use.

It is also considered more orderly as the order of receipt of materials is easily identifiable. Correct tracking ensures accurate inventory valuation, which in turn leads to more reliable financial reporting and better decision-making. To clarify where WIP inventory falls in the production process, let’s look at it in the larger context of other inventory classifications. All of the following terms are under the umbrellas of manufacturing inventory. In this article, we’ll cover the importance of classifying WIP inventory, how to calculate it, and how you can use the insights to optimize your inventory management. Using our work in process inventory calculator will automate your calculations.

This will reduce the delays in the production of the product, and the quality will not be compromised. Now, the main question is why this WIP inventory is important in the supply chain and what its role is. No product can be in more than one of the above categories at the same time. An item’s progress to completion may influence its value in WIP calculations. It ultimately comes down to the specific accounting method used – we’ll go into more detail on this later on. Somewhere along your chain, there is something work in progress inventory slowing your production output.

Calculating WIP Inventory: Formula and Step-By-Step Guide for Manufacturers

Since so many things can go wrong during a production cycle, simple calculations are best when you want to get a solid estimate on WIP inventory costs. Most companies don’t account for potential negative scenarios, like spoilage, leftovers or scrap materials, operational downtime, or maintenance, repair, and operation (MRO) inventory. If a manufacturer is constantly starting and stopping production, it can be costly and inefficient. With some WIP on hand, manufacturers can keep the assembly line moving even when disruptions or slowdowns occur. This helps to even out production and make the manufacturing process more efficient.

WIP inventories are goods or products in the intermediate stages of the production process. It represents the value of materials, labor, and overhead costs that you’ve already spent but haven’t finished transforming into the end product. Despite its many advantages, managing work in process inventory can present some challenges for businesses depending on their size and complexity level.
