Work in Process WIP Inventory Guide + Formula to Calculate

Work in process 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. WIP is calculated as a sum of WIP inventory, total direct labor costs, and allocated overhead costs. Therefore, all the factors that influence how effective your WIP management is – labor costs, production optimization, raw material costs, lead times – can be improved by choosing the right supplier. Simply sourcing materials from a supplier closer to your fulfillment centers can drastically reduce costs.

Thankfully, there is a formula, and once you have a grasp it’s going to be easy sailing from there on in. Work in process is generally used for unfinished products that will be turned into finished products soon. As such, the difference between WIP and finished goods is based on an inventory’s stage of completion relative to its total inventory.

Reducing WIP manufacturing costs

Whenever direct labor is incurred there is a debit to the work-in-process inventory and a credit to the wages payable account. For each direct labor hour incurred, the firm must debit work-in-process and credit a manufacturing overhead account. Once the goods are complete, the cost of the goods will be a debit to the finished goods inventory account how to find work in process inventory and a credit to the work-in-process account. 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.

Calculating work in process is essential for any company, as it tells investors how much a company has in production.

Instead, work-in-process should move between work centers one unit at a time, with very little inventory piling up between workstations.

Managing an inventory is an essential part of any supply chain management. It can be challenging to keep up with the demands of a growing business.
