Depreciation
Accounting method for allocating asset cost over useful life.
Depreciation is an accounting concept that refers to the reduction in the fair value of a tangible asset over time due to use and wear, as well as the allocation of the asset's original cost across the periods in which it is used. It is a fundamental principle in accountancy for both financial reporting and tax purposes, affecting the balance sheet and income statement of a business.

Lore & Background
Depreciation expense does not require a current outlay of cash and is a non-cash expense added back on the statement of cash flows. Accumulated depreciation is a contra account on the balance sheet, preserving historical cost. Common methods include straight-line depreciation, which divides the cost minus salvage value by the useful life in years.
Reader's Guide
Depreciation is significant because it allows businesses to match the cost of long-term assets with the revenue they generate, adhering to the matching principle. It affects net income and tax liability, and its methods—such as straight-line—provide a systematic way to allocate costs. The concept also includes impairment for unexpected declines in value and distinguishes between depreciation for tangible assets, depletion for natural resources, and amortization for intangibles. Depreciation's impact on cash flow is indirect, as it is a non-cash expense that reconciles net income with cash from operations. Accumulated depreciation on the balance sheet shows the total depreciation taken, preserving the asset's historical cost. The rules for depreciation vary by country, with some specifying lives and methods, while others allow choice based on business experience. Overall, depreciation is a cornerstone of financial accounting, enabling accurate profit measurement and asset valuation.
Did You Know?
- Depreciation is technically a method of allocation, not valuation, even though it determines the value placed on the asset in the balance sheet.
- Depreciation expense does not require a current outlay of cash and is a non-cash expense added back on the statement of cash flows.
- Accumulated depreciation is known as a contra account because it separately shows a negative amount directly associated with an accumulated depreciation account on the balance sheet.
- Straight-line depreciation is the simplest and most often used method, calculated by dividing the difference between cost and salvage value by the useful life in years.
Frequently Asked Questions
Who is Depreciation?
Depreciation is a core accounting principle that tracks how a tangible asset's value erodes over time from wear, use, or obsolescence. It also represents the systematic spreading of that asset's original purchase price across every accounting period during which the business actually benefits from it.
What are Depreciation's powers/role?
Its primary role is to allocate an asset's cost over its estimated useful life, ensuring expenses match the periods that generate revenue. On the books, it simultaneously reduces the asset's carrying value on the balance sheet and adds a non-cash expense line to the income statement.
How does Depreciation's story end?
Depreciation stops once the asset reaches its salvage (residual) value or is retired from service, whichever comes first. At that point the asset is fully depreciated, and no further periodic charges are recorded against it.
Why is Depreciation important?
It keeps a company's financial statements honest by preventing a one-time lump-sum hit when an expensive asset is bought, instead smoothing the cost across years of use. It also directly shapes taxable income, making it a critical lever for both reporting accuracy and tax planning.
What are Depreciation's close allies and rivals?
Its closest relatives are amortization (which handles intangible assets) and depletion (which applies to natural resources), while impairment is the harsher cousin that writes down value abruptly rather than gradually. Together they form the broader family of asset-cost allocation methods in accountancy.
