Depreciation



Depreciation

In accounting, Depreciation refers to the systematic allocation of the depreciable amount of an asset over its useful life. It represents the decrease in the value of a fixed asset due to its usage, wear and tear, passage of time, or obsolescence. Fixed assets, also known as non-current assets (like machinery, buildings, vehicles, furniture), are purchased for long-term use in the business operations and are not intended for immediate sale.


Over time, these assets lose their capacity to provide services. Depreciation is the accounting mechanism to recognise this loss in value and systematically spread the cost of the asset over the periods that benefit from its use. It is an expense related to the use of a long-term asset.


Meaning Of Depreciation

Depreciation is essentially a process of cost allocation, not a process of asset valuation. Its purpose is to charge a portion of the asset's cost as an expense in each accounting period during its useful life, reflecting the consumption of the asset's economic benefits. It is based on the Matching Concept, aiming to match the cost of using the asset with the revenue generated from its use in the same period.


Features Of Depreciation

Providing depreciation is mandatory under the Companies Act, 2013, and accounting standards in India.



Depreciation And Other Similar Terms

While depreciation refers to the decline in value of tangible fixed assets due to usage or time, there are similar concepts used for other types of long-term assets.


Depletion

Depletion refers to the process of allocating the cost of wasting assets (natural resources) over the period they are extracted or consumed. Wasting assets include mines, quarries, oil wells, forests, etc., whose value decreases as the underlying natural resource is physically removed or used up.

Key Difference from Depreciation:

Depreciation is for tangible assets created or acquired by humans (like machinery), while depletion is for natural resources. Depletion is often calculated based on the quantity of the resource extracted during the period.

$Depletion\ Charge\ per\ Unit = \frac{Cost\ of\ Asset - Estimated\ Residual\ Value}{Estimated\ Total\ Units\ in\ Asset}$

$Total\ Depletion\ for\ Period = Depletion\ Charge\ per\ Unit \times Units\ Extracted\ during\ Period$

Example 1. Calculating Depletion.

A company purchases mining rights for a coal mine for ₹10,00,000. The estimated total coal in the mine is 1,00,000 tonnes. In the first year, the company extracts 10,000 tonnes.

Answer:

Depletion Charge per Tonne = $\frac{₹10,00,000}{1,00,000\ tonnes} = ₹10$ per tonne.

Total Depletion for the first year = ₹10/tonne $\times$ 10,000 tonnes = ₹1,00,000.

This ₹1,00,000 will be charged as an expense (Depletion Expense) in the Profit and Loss Account.


Amortisation

Amortisation refers to the systematic allocation of the cost of intangible assets (assets without physical substance) over their useful lives. Intangible assets include goodwill, patents, trademarks, copyrights, software, licenses, etc.

Key Difference from Depreciation and Depletion:

Amortisation is for intangible assets. Unlike tangible assets or natural resources, intangible assets do not physically wear out. Their value declines over time due to factors like the expiration of legal rights (for patents, copyrights) or the fading of their economic usefulness. The process of amortisation is similar to depreciation methods (like straight-line).

Example 2. Amortising a Patent.

A company purchases a patent for ₹5,00,000. The patent has a legal life of 20 years, but the company estimates its useful economic life will only be 10 years due to rapid technological changes.

Answer:

The patent will be amortised over its useful economic life of 10 years, not its legal life of 20 years, if the useful life is shorter.

Annual Amortisation (using straight-line) = $\frac{₹5,00,000}{10\ years} = ₹50,000$ per year.

This ₹50,000 will be charged as an expense (Amortisation Expense) in the Profit and Loss Account each year.

In essence:

All three are methods of allocating the cost of a long-term asset over its useful life and are treated as expenses in the Profit and Loss Account.



Causes Of Depreciation

Fixed assets lose their value and ability to provide services over time due to various factors. Understanding these causes helps explain why depreciation is necessary.


Wear And Tear Due To Use Or Passage Of Time

This is the most common cause of depreciation for physical assets.

This physical depreciation is a primary reason for allocating the asset's cost over its useful life.


Expiration Of Legal Rights

This applies primarily to intangible assets, but can also affect the useful life of tangible assets if their use is tied to a legal right. Assets like patents, copyrights, licenses, and leases have a limited legal life. Their value declines as the period of legal protection or right expires.

Example 3. Expiration of Legal Rights.

A company holds a license to operate a specific type of business that is valid for 10 years. The value of this license will decrease over these 10 years as its legal right expires.

Answer:

The cost of this license would be amortised over its 10-year legal life, reflecting the loss of value due to the passage of time and expiration of the legal right.

For a tangible asset, if its use is tied to a 5-year lease, even if the asset could physically last longer, its depreciable life is limited by the lease term.


Obsolescence

Obsolescence refers to the decline in the value of an asset due to factors other than physical wear and tear. The asset is still physically capable of performing its function, but it becomes outdated, inefficient, or less desirable compared to newer alternatives.

Causes of Obsolescence:

Example 4. Obsolescence.

A printing business in Chennai owns letterpress printing machines. With the advent of offset and digital printing technologies, these letterpress machines, while still functional, may become obsolete due to being slower, less versatile, and more expensive to operate compared to new machines.

Answer:

The decline in the economic value of the letterpress machines due to the availability of superior technology is obsolescence, a cause of depreciation/decline in value.

Obsolescence can shorten the useful life of an asset, requiring faster depreciation.


Abnormal Factors

Unforeseen events or accidents can cause a sudden and significant decrease in the value of an asset. While not a systematic cause like wear and tear or obsolescence, they contribute to the overall decline in value over time or necessitate immediate write-down.

Examples:

While these events might lead to an immediate loss or write-down of the asset (which is distinct from regular depreciation), they contribute to the cumulative loss in value of the asset during its life.

All these factors contribute to the decline in the economic value of fixed assets over their useful life, necessitating the accounting practice of depreciation.



Need For Depreciation

Providing for depreciation is not just an arbitrary accounting rule; it serves several crucial purposes, contributing to the accurate representation of a business's financial performance and position.


Matching Of Costs And Revenue

This is a core reason for charging depreciation, aligning with the Matching Concept. Fixed assets are used to generate revenue over multiple accounting periods. The cost of the asset is essentially a prepaid expense spread over its useful life. Depreciation ensures that a portion of the asset's cost (which contributes to revenue generation) is charged as an expense in the same accounting period in which that revenue is earned.

Example 5. Matching Concept and Depreciation.

A business buys a machine for ₹10,00,000 with a useful life of 10 years to manufacture goods. This machine helps generate ₹5,00,000 in revenue each year.

Answer:

Instead of charging the entire ₹10,00,000 cost of the machine as an expense in the year of purchase, depreciation (say, ₹1,00,000 per year using straight-line method) is charged annually.

This matches the ₹1,00,000 expense of using the machine with the ₹5,00,000 revenue it helped generate in that year, providing a more accurate profit figure (₹5,00,000 revenue - ₹1,00,000 depreciation - other expenses).

Without depreciation, the first year's profit would be understated (burdened by the full asset cost), and subsequent years' profits would be overstated (benefiting from the asset's use without its cost being recognised).


Consideration Of Tax

Depreciation is a deductible expense for calculating taxable profit under the Income Tax Act, 1961, in India. Businesses are required to calculate and provide depreciation as per the rates and rules specified in the Income Tax Act to arrive at the correct taxable income.

Tax laws often provide for depreciation as a legitimate business expense.


True And Fair Financial Position

Providing depreciation ensures that the value of fixed assets shown in the Balance Sheet is presented more realistically. The Balance Sheet shows assets at their book value (Original Cost - Accumulated Depreciation).

Thus, depreciation contributes to the objective of preparing financial statements that show a true and fair view of the financial position of the business.


Compliance With Law

The Companies Act, 2013, in India mandates that companies must provide for depreciation on their fixed assets according to the rates and methods prescribed. The Income Tax Act, 1961, also specifies rules for calculating depreciation for tax purposes.

Legal requirements enforce the practice of depreciation, ensuring consistency and accuracy in financial reporting.



Factors Affecting The Amount Of Depreciation

The amount of depreciation to be charged for an accounting period depends on several factors related to the fixed asset. Different methods of depreciation use these factors in different ways, but they are the core inputs for calculation.


Cost Of Asset

This is the initial cost incurred to acquire the asset and bring it to its working condition and location for its intended use. According to the Cost Concept, assets are recorded at their historical cost.

Elements included in the Cost of Asset:

The total of these costs forms the basis for calculating depreciation.


Estimated Net Residual Value (or Salvage Value)

This is the estimated value that the business expects to realise from the disposal of the asset at the end of its useful life. It is the expected scrap value or resale value.

If the estimated residual value is significant, it reduces the amount that needs to be depreciated over the asset's life.


Depreciable Cost

The Depreciable Cost of an asset is the portion of its cost that is subject to depreciation. It is the original cost of the asset minus its estimated net residual value. This is the amount that will be allocated as depreciation expense over the asset's useful life.

Depreciable Cost = Cost of Asset - Estimated Net Residual Value

Example 6. Calculating Depreciable Cost.

A machine is purchased for ₹5,00,000. Installation costs are ₹50,000. The estimated scrap value at the end of its life is ₹20,000.

Answer:

Cost of Asset = Purchase Price ₹5,00,000 + Installation Costs ₹50,000 = ₹5,50,000.
Estimated Net Residual Value = ₹20,000.
Depreciable Cost = ₹5,50,000 - ₹20,000 = ₹5,30,000.

The amount to be depreciated over the asset's useful life is ₹5,30,000.


Estimated Useful Life

The Estimated Useful Life is the period over which the asset is expected to be available for use by the business, or the number of production units or similar units expected to be obtained from the asset by the entity.

The depreciable cost is spread over this estimated useful life using an appropriate depreciation method (e.g., Straight Line, Written Down Value).

Using the Straight Line Method (where depreciation is constant each year):

$Annual\ Depreciation = \frac{Depreciable\ Cost}{Estimated\ Useful\ Life\ (in\ Years)}$

$Annual\ Depreciation = \frac{Cost\ of\ Asset - Estimated\ Net\ Residual\ Value}{Estimated\ Useful\ Life\ (in\ Years)}$

Example 7. Calculating Annual Depreciation (Straight Line).

Using the figures from Example 6, assume the estimated useful life of the machine is 10 years.

Answer:

Depreciable Cost = ₹5,30,000.
Estimated Useful Life = 10 years.
Annual Depreciation = $\frac{₹5,30,000}{10\ years} = ₹53,000$.

₹53,000 will be charged as depreciation expense each year for 10 years (assuming straight-line method).

These three factors – Cost, Residual Value, and Useful Life – are essential for calculating the amount of depreciation to be charged periodically, regardless of the method used.
