Key Differences

Depreciation is an accounting method used to allocate the cost of a tangible or intangible asset over its useful life. This process reflects the wear and tear or ageing of the asset. Whereas, obsolescence occurs when an asset becomes outdated or no longer useful, regardless of its physical condition, often due to technological advancements or changes in market preferences.
Depreciation is typically calculated using systematic methods such as straight-line, declining balance, or units of production, ensuring predictability in financial reporting. On the other hand, obsolescence can be unpredictable and may occur suddenly due to external factors like new innovations or regulatory changes impacting an asset's relevance.
Assets depreciate over time due to usage, wear and tear, or merely the passage of time. This affects mostly physical assets like machinery and buildings. Whereas obsolescence can affect both physical and intangible assets, such as software, which may become obsolete due to technological advancements even if it's still in good working condition.
Depreciation is a planned and anticipated expense that businesses use for budgeting and tax purposes, helping them manage cash flow and financial planning. In contrast, obsolescence can lead to unplanned financial losses, requiring businesses to adapt quickly by investing in new technologies or changing business strategies.
Depreciation affects the book value of an asset on a company’s balance sheet, gradually reducing the asset's value. On the other hand, obsolescence can lead to a more immediate and sometimes total loss of value, potentially requiring the asset to be written off completely if it becomes irreversibly outdated.

Depreciation

In accountancy, depreciation refers to two aspects of the same concept: first, the actual decrease of fair value of an asset, such as the decrease in value of factory equipment each year as it is used and wear, and second, the allocation in accounting statements of the original cost of the assets to periods in which the assets are used (depreciation with the matching principle).Depreciation is thus the decrease in the value of assets and the method used to reallocate, or "write down" the cost of a tangible asset (such as equipment) over its useful life span. Businesses depreciate long-term assets for both accounting and tax purposes.

Obsolescence

Obsolescence is the state of being which occurs when an object, service, or practice is no longer maintained, required, or degraded even though it may still be in good working order.The international standard IEC 62402:2019 Obsolescence Management defines obsolescence as the "transition from available to unavailable from the manufacturer in accordance with the original specification".Obsolescence frequently occurs because a replacement has become available that has, in sum, more advantages compared to the disadvantages incurred by maintaining or repairing the original. Obsolete also refers to something that is already disused or discarded, or antiquated.
