Work-in-Process WIP Inventory: Definition, How It Works, & Formula

However, the firm only used half of the wood in the actual chair manufacturing process. The builders worked 50 hours each on chair manufacturing during the period. The firm applies all manufacturing overhead costs to products based on direct labor hours. To calculate ending work-in-process, the firm must first solve for total manufacturing costs for the period.

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 represents incomplete goods still in the production process, i.e. the manufacturing stage between raw materials and finished goods. 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.

A piece of inventory becomes labeled as work-in-progress when raw material combines with human labor. When the product is finalized, it switches from WIP to being categorized as a finished product. Finally, when the product is sold, it moves from a form of inventor to cost of goods sold on the balance sheet. A work-in-progress is the cost of unfinished goods in the manufacturing process including labor, raw materials, and overhead. Cost of processing is significant because each semi-finish product moves through the various manufacturing steps. A firm accounts for the work in progress towards the end of the accounting period. The accounting of WIP helps a company to determine the value of inventory that is in the production process.

Advantages of Work In Process

Managing WIP inventory requires coordination between several functions within a company, as well as with suppliers and customers. Higher WIP inventory levels are advantageous in that they can support a surge in demand, as well as improve cycle time since there is more material in production. However, this can also increase storage costs and obsolescence risk, as well as lead to waste if demand is lower than expected.
