Work in Process WIP Inventory Guide + Formula to Calculate

work in process

Businesses always calculate WIP inventory at the end of accounting periods, whether that be a quarter, year, or some other time period. 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. The above work in process inventory definition explains the what, but not the why. Figuring out WIP inventory is an involved process because it involves associating a cost with a percentage of completion. And that’s why it’s standard practice to minimize WIP inventory before reporting.

What is a negative WIP?

Negative WIP represents the value of work you've invoiced that you've yet to do. This is a current liability to your practice as you have a present obligation to deliver future services to your customers arising from a past transaction (the invoice).

For example, this could include a building that’s only partially completed. The amount that the company has spent on the incomplete construction of a long-term asset would fall under work-in-progress. That amount would show up on a line item on the company’s balance sheet in long-term assets under the property, plant and equipment line item. This inventory stays on a company’s balance sheet or is written off based on the duration of time it spends on the production floor. For accounting purposes, 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. Any part, product, or item that’s used to make merchandise inventory is listed on a company’s balance sheet.

What Are the Implications of Using LIFO and FIFO Inventory Methods?

To complicate matters, companies that produce items under a long-term contract will use an account entitled Construction-in-Process. Accounting treatment for the two vary, as work in process is usually reported as a current asset while work in progress is usually reported as a non-current asset. The figures for both work in progress and work in process are listed on a company’s balance sheet. Subsequently, once the Raw Materials are sent for processing, Work In progress Inventory is debited for the amount, and Raw Material inventory is credited.

  • The beginning WIP inventory cost refers to the previous accounting period’s asset section of the balance sheet.
  • WIP is calculated as a sum of WIP inventory, total direct labor costs, and allocated overhead costs.
  • WIP also excludes the value of the finished product that is anticipated to be future sales.

The firm’s work in process includes those materials from the time of release to the work floor until they become complete and ready for sale to wholesale or retail customers. A good only partially completed during the manufacturing process is called work in process. Lean production principles consider excess WIP to be an indicator of waste caused by bottlenecks in the manufacturing process or an unstable supply chain.

Your question points out the need for caution and an understanding of what the communicator intends. Keep in mind that the sender of a message might not realize that there are important differences between slightly different terms.

  • Be mindful of acronyms when analyzing a company’s financial statement, as it is common for both terms to be shortened to «WIP.»
  • Total WIP Costs are calculated as a sum of WIP Inventory + Direct Labor Costs + Overhead costs.
  • It might be helpful to think of progress as gradual change for the better, while a process is a sequence of discrete steps toward a predetermined goal.
  • On a balance sheet, work in progress is considered to be an asset because money has been spent towards a completed product.
  • To calculate the overhead rate, take the overhead costs budgeted, and divide them by the estimated cost driver (e.g. machine or labor).
  • Construction companies may use specific work in progress accounts.

For example, consider a 40-story skyscraper that is 75% complete; it may be warranted for a company to recognize additional financial benefits beyond costs as a FMV adjustment. Work in progress is sometimes used to refer to assets that require a considerable amount of time to complete. The underlying assumption regarding work in progress is there is larger project framework in play that requires a heavier investment in time for the process. Although some companies use more specific types of general ledger accounts for construction projects, a large build may be considered an example of work in progress. The difference between work in progress and finished goods is a measure of completion of the inventory stage from the raw material. WIP and finished goods refer to the intermediary and final stages of an inventory life cycle, respectively. Knowing how many WIP units you have and how much they cost you is important so you can track your production costs.

How to Calculate Work In Process Inventory

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. Free up storage space for finished goods that are work in process ready to create revenue. Over the next three months, the company incurs production costs of $75,000 roasting, grinding, and packaging coffee beans. The total value of the finished goods over the quarter is $72,000.

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. Imagine BlueCart Coffee Co. has a beginning work in process inventory for the quarter of $10,000. This refers to all the bags, labels, beans yet-to-be-ground, and other raw materials waiting to be turned into finished bags of coffee ready for sale.

Accounting Topics

In some cases, a finished good still needs other components to go to market. Alternatively, companies assign a standard percentage of the entire WIP items.

Before attempting to calculate your current WIP inventory value, here are some terms you will need to know first. Construction companies may use specific work in progress accounts. Often indicating very similar types of work, this may include work in progress, construction in progress, or construction work in progress. Also, it is a temporary account, and not all companies have a compulsion to maintain this account. This is because certain products do not need to have a longer work in progress process. Even if all work is completed on a WIP unit and it becomes a finished good, it doesn’t necessarily mean the unit is ready to hit the shelves and be sold to consumers.
