Brief Definition
Net book value (NBV) is the value of an asset as recorded on a company’s balance sheet after accounting for accumulated depreciation or amortization. It represents the remaining value of an asset that has not yet been fully depreciated or amortized. NBV is an important measure for financial reporting and analysis.
Further Explanation
Net book value (NBV) is a term used in accounting and finance to refer to the value of an asset on a company’s balance sheet after accounting for accumulated depreciation or amortization. It is calculated by subtracting the accumulated depreciation or amortization from the original cost or purchase price of the asset.
In other words, net book value represents the remaining value of an asset that has not yet been depreciated or amortized, and is used to determine the value of the asset for accounting and financial reporting purposes.
For example, if a company purchases a piece of equipment for $10,000 and depreciates it by $2,000 per year over a five-year period, the net book value of the equipment at the end of the first year would be $8,000 ($10,000 original cost minus $2,000 accumulated depreciation). At the end of the second year, the net book value would be $6,000 ($10,000 original cost minus $4,000 accumulated depreciation), and so on.
Net book value is an important concept in accounting and finance, as it helps to determine the value of a company’s assets for financial reporting and analysis purposes. It is often used in conjunction with other financial metrics, such as market value and replacement cost, to provide a comprehensive picture of a company’s financial health and performance.
