Should depreciation be charged on working progress?

Depreciation is typically not charged on work in progress (WIP) because WIP consists of materials and labor that are not yet completed products. Depreciation applies to fixed assets, such as machinery or equipment, that are used in the production process. Instead, costs associated with WIP are generally capitalized until the products are completed and ready for sale, at which point they can be included in the cost of goods sold. Therefore, WIP itself does not incur depreciation.
