Meaning
Value reduction of early stage models occurs as they are superseded by advanced versions or as they wear out during testing. Through prototype depreciation, a company accounts for the declining utility of its experimental hardware or software over time. This accounting treatment stops when the asset is either fully written off or replaced by a commercial product.
Technical Obsolescence
Rapid innovation makes early versions of a product less useful for further development. When prototype depreciation is calculated, the speed of technological change is a major factor in determining the life of the asset. A model that was useful six months ago might be completely irrelevant once a new sensor or software library is integrated.
Asset Evaluation
Costs associated with building an initial version are capitalized and then gradually reduced on the balance sheet. In prototype depreciation, the expense is spread over the expected period of use to avoid an immediate full deduction. This approach matches the cost of the development with the period in which the development provides value to the firm.
For a complex piece of machinery, this might involve tracking the hours of operation and the wear on specific components. If a component fails during a high stress test, the remaining value of that part might be written down immediately.
Residual Value
Salvageable parts or materials might remain after a test model is retired. At the end of prototype depreciation, the company determines if any pieces can be reused or sold for scrap. This final value is subtracted from the total cost before the final accounting entry is made.
