Depreciation
Definition
The systematic allocation of a tangible asset's cost over its useful life. Depreciation reduces the book value of physical assets such as machinery, vehicles, and buildings on the balance sheet while recording the expense on the income statement. While depreciation applies to tangible assets, its intangible counterpart — amortisation — follows similar principles under IAS 38, systematically allocating the cost of intangible assets with finite useful lives over their expected economic life.
Complementary Terms
Concepts that frequently appear alongside Depreciation in practice.
The gradual write-off of an intangible asset's cost over its useful life. Unlike depreciation (which applies to physical assets), amortisation spreads the expense of assets such as patents, software, and licences across the income statement over the period they generate value.
A cost approach valuation technique that estimates the fair value of an intangible asset as the current cost to create a functionally equivalent asset, less deductions for all forms of depreciation including physical deterioration (not applicable to intangibles), functional obsolescence, technological obsolescence, and economic obsolescence. The method is commonly applied to software, assembled workforce (when valued), and databases where the cost to recreate can be estimated from development effort, labour rates, and project timelines.
A form of asset value decline that can be economically remedied through repair, upgrade, or redesign at a cost that is less than the resulting increase in value. In the context of intangible assets, curable depreciation might apply to software requiring modernisation or a brand needing repositioning.
A form of asset value decline that cannot be economically remedied because the cost of correction exceeds the resulting increase in value, or because the cause is external and beyond the owner's control. In intangible asset valuation, incurable depreciation often arises from economic obsolescence, permanent market shifts, or fundamental changes in regulatory environment.
A physical asset, such as land, buildings, plant and machinery, vehicles or inventory. Under IAS 16 and FRS 102 Section 17, property, plant and equipment is carried at cost less depreciation or, where an entity adopts the revaluation model for a whole class of assets, at a revalued amount; land is not depreciated.
The accounting practice of recording an intangible expenditure as an asset on the balance sheet rather than expensing it immediately through the income statement. Under IAS 38, development costs must be capitalised once the six criteria in IAS 38.57 are met, whereas research costs must always be expensed.
Book value is the net asset value of a company as recorded on its balance sheet — total assets minus total liabilities. The formula is simple: Book Value = Total Assets − Total Liabilities.
The total value of a company's or fund's assets minus its liabilities. For investment funds, NAV represents the per-share or per-unit value.

What is the difference between tangible and intangible assets?
Tangible assets have physical form: land, buildings, machinery, vehicles and stock. Intangible assets have none: they are identifiable non-monetary assets such as patents, trade marks, software and customer contracts.

ASC 350-40 requires capitalisation of internal-use software development costs during the application development stage, while preliminary project and post-implementation costs must be expensed.

Finite-life intangibles (patents, customer lists, licences) are amortised over useful life; indefinite-life intangibles (brands, market position) are tested annually for impairment.
