What is Work in Process (WIP) Inventory and How to Calculate It

To accurately determine your current WIP inventory value, you need to first determine the cost of manufactured goods. To determine your COGM, you will need to add your beginning WIP inventory with your total manufacturing costs and then subtract the ending inventory. Now the firm calculates total manufacturing costs for the period by adding the $500 cost of direct materials used, $1,000 direct labor incurred, and $200 manufacturing overhead costs. Similarly to inventory and raw materials, the WIP inventory is accounted for as an asset in the balance sheet. 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. For the majority of manufacturers, WIP inventory is the raw materials plus labor and production overhead.

These are the beginning WIP inventory value, the total manufacturing cost, and the cost of manufactured goods, also known as COGM. All direct labor costs accumulated in the manufacturing process are also included. These are comprised of the wages and salaries of all employees involved directly in the production process like machine beginning work-in-process inventory formula operators, skilled workers, etc., who personally handle the products. Any raw material inventory that humans have worked on but is not yet considered a finished good is a work-in-process inventory. You can think of WIP inventory as all inventory that has not yet reached the finished product inventory but is not raw materials.

While work in process inventory isn’t sitting on a shelf waiting to be sold, it does need to be stored somewhere. Paying to store too much unsellable inventory can seriously impact a brand’s bottom line—and not in a good way. The formula to calculate WIP is WIP Inventory + Direct Labor Costs + Overhead costs. The time required to make a good or product, in this case, a building, is much longer and requires more material and manpower as compared to a factory or consulting project. In contrast, Work-In-Progress refers to a production process that requires a longer time frame.

Though some within supply chain management do make a small distinction between them. Some folks refer to work in process inventory only in the context of production operations that move along relatively quickly. They reserve work in progress for larger-scale projects like consulting or construction work.

It encompasses all the costs incurred during the creation of the final product. If materials wait around too long and become obsolete or spoiled, it will cause problems in the supply chain. When WIP inventory remains consistent, or you’re able to keep low stocks without losing out on sales, it’s an indication that your production operations are working efficiently. Examining your WIP inventory process can reveal gaps in your supply chain, unneeded costs, and the strength of your suppliers. The whole process is based on flow – bringing sellable inventory from a manufacturer, through a supply chain, and to your business.

• Calculating the cost of in-process inventory is relatively complicated compared to calculating the cost of finished goods.
• As the name implies, WIP inventory accounting involves keeping track of the costs of unfinished goods as they move through the production process.
• Generally speaking, best practice is to carry as little WIP Inventory as possible.
• Longer WIP Stage → The longer the items remain in the work in progress stage, the less efficient that company may be – all else being equal.
