Meaning and Features of Depreciation
Depreciation represents the gradual and permanent shrinkage in the book value of fixed assets due to usage, time, or obsolescence.
In accounting, the matching principle requires that expenses incurred to earn revenue in a specific period must be matched against that revenue. When a business purchases a long-term asset like machinery, the cost provides benefits over several years. Therefore, it is illogical to charge the entire cost in the year of purchase. Instead, the cost is spread over the asset's useful life.
Depreciation is an 'expired cost' or a non-cash expense. It does not involve an actual outflow of cash but represents the allocation of the historical cost of the asset. It is based on the book value of the asset rather than its market value, ensuring that the financial statements reflect a true and fair view of the business's position.
Key features include its continuous nature and its role as a charge against profit. By deducting depreciation before calculating tax, a business correctly identifies its taxable income. Common examples of depreciable assets include furniture, computers, trucks, and plant machinery.

Depletion and Amortisation
While depreciation applies to tangible fixed assets, similar concepts exist for natural resources and intangible assets.
Depletion is the term used for the exhaustion of natural resources such as mines, quarries, or oil wells. As the physical quantity of the resource is extracted (e.g., tons of coal from a mine), the value of the asset declines. The primary difference is that depletion relates to the physical exhaustion of a resource, whereas depreciation relates to the usage of a manufactured asset.
Amortisation refers to the periodic writing-off of the cost of intangible assets. These are assets without physical form but with significant legal or commercial value, such as patents, copyrights, trademarks, and goodwill. If a firm buys a patent for 10,00,000 with a 10-year life, it must amortise 1,00,000 annually.
Despite the different names, the accounting treatment for depreciation, depletion, and amortisation is essentially the same: they all represent the expiry of an asset's service potential and are charged against revenue.
| Term | Asset Type | Cause of Value Decline |
|---|---|---|
| Depreciation | Tangible Fixed Assets (Machinery, Furniture) | Wear and tear, passage of time, obsolescence |
| Depletion | Natural Resources (Mines, Oil Wells) | Physical extraction or exhaustion |
| Amortisation | Intangible Assets (Patents, Copyrights) | Expiry of legal rights or utility over time |

Causes and Need for Charging Depreciation
Understanding why assets lose value and why accounting for this loss is mandatory for business transparency.
The most common cause of depreciation is wear and tear resulting from use in business operations. However, assets also deteriorate simply with the passage of time (effluxion of time) due to exposure to nature, even if not used. Obsolescence is another major factor, where an asset becomes out-of-date because of technological advancements or changes in market demand.
Legal rights expiration also causes value loss. For instance, a leasehold property or a patent loses its utility once the legal agreement governing its use ends. Abnormal factors like accidents, fire, or floods can cause a sudden, permanent decline in an asset's usefulness.
The need for depreciation is rooted in the Matching Principle. To calculate true profit, all costs (including asset wear) must be deducted from revenue. Furthermore, providing for depreciation ensures the Balance Sheet shows a 'true and fair' view of assets, prevents overvaluation, and ensures compliance with tax and corporate laws.

Factors Affecting Depreciation Amount
Three primary parameters determine how much depreciation is charged: Cost, Residual Value, and Useful Life.
The 'Cost of Asset' (Historical Cost) includes the invoice price plus all expenses necessary to bring the asset to a working condition. This includes freight, transit insurance, installation costs, and registration fees. For second-hand assets, initial repair costs to make them workable are also capitalized.
The 'Estimated Net Residual Value' (Scrap or Salvage Value) is the amount expected to be realized from the sale of the asset at the end of its useful life, minus any disposal expenses. For example, if a machine costs 50,000 and is expected to sell for 6,000 after 10 years with 1,000 disposal costs, the net residual value is 5,000.
The 'Estimated Useful Life' is the period over which the asset is commercially viable for the enterprise. This is often shorter than the asset's physical life. It can be measured in years, units of output, or working hours. The 'Depreciable Cost' is the total amount to be written off, calculated as: Total Cost minus Net Residual Value.
Calculating Depreciable Cost
Depreciable Cost = Cost of Asset - Net Residual Value
Using the source example: If a machine is purchased for 50,000 and its net residual value is 5,000 (6,000 sale price minus 1,000 disposal cost), the Depreciable Cost = 50,000 - 5,000 = 45,000.

Straight Line Method (SLM)
Also known as the Fixed Installment Method, SLM charges an equal amount of depreciation every year.
The Straight Line Method assumes that the asset's utility is uniform throughout its life. Under this method, a fixed percentage of the original cost is written off annually. If plotted on a graph, the depreciation amount remains a horizontal straight line over time.
The main advantage of SLM is its simplicity. It allows an asset to be depreciated down to zero or its exact scrap value. It is most suitable for assets where usage is consistent and repair costs don't rise drastically, such as leasehold buildings or patents.
However, SLM is criticized for being unrealistic because most assets lose more utility in their early years. Additionally, as the asset ages, repair costs typically increase. Since the depreciation charge is fixed, the total burden (Depreciation + Repairs) on the Profit and Loss account increases over time, which can distort annual profit comparisons.
SLM Calculation Process
- 1
Determine Total Cost
Purchase Price + Installation + Freight
- 2
Subtract Scrap Value
Estimate the net amount realizable at the end of the asset's life
- 3
Divide by Useful Life
Divide the depreciable cost by the number of years of expected use
- 4

Written Down Value Method (WDV)
Also known as the Reducing Balance Method, WDV applies a fixed percentage to the diminishing book value of the asset.
Under the WDV method, depreciation is calculated on the book value (cost minus accumulated depreciation) at the beginning of each year. Consequently, the amount of depreciation is highest in the first year and decreases every subsequent year.
This method is considered more realistic because it matches the decreasing utility of the asset as it ages. It also balances the total charge to the Profit and Loss account: in early years, depreciation is high and repairs are low; in later years, depreciation is low and repairs are high. This results in a more uniform total burden over the asset's life.
WDV is the method recognized by the Income Tax Act in India. It is highly suitable for assets like plant, machinery, and vehicles that are subject to rapid technological change and increasing maintenance costs. A limitation is that the asset value can never technically reach zero under this method.
WDV Calculation Example
Year 1: 10% of 2,00,000 = 20,000; Year 2: 10% of (2,00,000 - 20,000) = 18,000
In Year 1, we calculate 10% on the original cost. In Year 2, we calculate 10% on the 'Written Down Value' of 1,80,000. The charge drops from 20,000 to 18,000.

Methods of Recording Depreciation
There are two distinct ways to maintain asset records in the ledger: charging directly to the asset or using a provision account.
In the first method, 'Charging to Asset Account', the depreciation amount is credited directly to the Asset Account at the end of each year. The asset appears in the Balance Sheet at its net book value (Cost minus Depreciation). The journal entry is: Depreciation A/c Dr. to Asset A/c.
In the second method, 'Creating Provision for Depreciation', the Asset Account is never disturbed and always shows the original historical cost. Instead, depreciation is accumulated in a separate 'Provision for Depreciation' or 'Accumulated Depreciation' account. The journal entry is: Depreciation A/c Dr. to Provision for Depreciation A/c.
The Provision method is often preferred because it keeps the original cost visible on the face of the Balance Sheet. When the asset is eventually sold or disposed of, the total accumulated depreciation is transferred from the Provision account to the Asset account to determine the final profit or loss.
| Feature | Charging to Asset | Provision for Depreciation |
|---|---|---|
| Asset Value in Ledger | Shown at Written Down Value | Shown at Original Cost |
| Depreciation Record | Credited to Asset Account | Credited to Provision Account |
| Balance Sheet Presentation | Asset shown at Net Value | Accumulated Dep. shown as deduction from Cost |
| Asset Account Stability | Changes every year | Remains constant until disposal |

Disposal of Assets and Disposal Account
When an asset is sold or discarded, the business must calculate the resulting profit or loss.
Disposal occurs when an asset reaches the end of its useful life or becomes obsolete prematurely. To find the profit or loss, the sale proceeds are compared with the book value on the date of sale. If proceeds exceed book value, it is a profit; otherwise, it is a loss.
If a 'Provision for Depreciation' account is maintained, the accumulated depreciation for the specific asset being sold must be transferred to the Asset Account (or Asset Disposal Account) before calculating the final profit or loss. This ensures the book value is correctly determined at the time of disposal.
An 'Asset Disposal Account' is often opened to provide a clear view of the transaction. The original cost of the asset is debited to this account, while accumulated depreciation and sale proceeds are credited. The resulting balance represents the profit or loss transferred to the P&L account.
Profit/Loss = Sale Proceeds - (Original Cost - Accumulated Depreciation)

Provisions: Accounting for Uncertainties
Provisions are amounts set aside out of profits to cover known liabilities or losses whose exact amount is not yet certain.
According to the principle of Prudence (Conservatism), a business must provide for all expected losses. A provision is a 'charge against profit,' meaning it must be created even if the business incurs a loss. It ensures that the current year's revenue is matched with the expected expenses related to that period.
Common examples include Provision for Doubtful Debts, Provision for Taxation, and Provision for Repairs and Renewals. For instance, a trader knows from experience that some customers (debtors) will not pay. By creating a Provision for Doubtful Debts, the trader accounts for this expected loss in the current year.
In the Balance Sheet, provisions are either deducted from the relevant asset (like Provision for Doubtful Debts from Debtors) or shown on the liabilities side (like Provision for Tax).

Reserves: Strengthening Financial Position
Reserves are appropriations of profit retained in the business to meet future contingencies or fund growth.
Unlike provisions, reserves are not meant to cover a known liability. They are created only when there are profits. Reserves strengthen the financial standing of the company and provide funds for expansion, redeeming long-term liabilities, or meeting unforeseen future needs.
Reserves are shown on the liabilities side of the Balance Sheet under the heading 'Reserves and Surplus,' following the Capital account. Examples include General Reserve, Capital Reserve, and Dividend Equalisation Reserve.
General Reserves are 'free reserves' that can be used for any purpose. Specific Reserves, like a Workmen Compensation Fund, are created for a particular purpose. While most reserves are voluntary, certain reserves like the Debenture Redemption Reserve are mandatory under law.
| Basis | Provision | Reserve |
|---|---|---|
| Nature | Charge against profit | Appropriation of profit |
| Purpose | Known liability (amount uncertain) | Strengthening financial position; some are mandatory under law |
| Compulsion | Mandatory even if no profit | Voluntary (usually) |
| Tax Effect | Reduces taxable profit | No effect on taxable profit |
| Dividends | Cannot be used for dividends | Can be used for dividends |

Revenue and Capital Reserves
Reserves are classified based on the nature of the profits from which they are created.
Revenue Reserves are created from 'revenue profits'—profits earned through normal day-to-day business operations. These are generally available for distribution as dividends to shareholders. Examples include General Reserve and Investment Fluctuation Fund.
Capital Reserves are created from 'capital profits'—profits that do not arise from normal operations. These include premiums on the issue of shares, profits on the sale of fixed assets, or profits on the revaluation of assets. Capital reserves are generally not available for dividend distribution and are used to write off capital losses or issue bonus shares.
The distinction is vital for legal compliance and ensuring that dividends are only paid out of earned operating surpluses rather than one-time capital gains.

Secret Reserves
A secret reserve is a reserve that exists but does not appear on the Balance Sheet.
Secret reserves are created by showing the net profit at a lower figure than it actually is. This can be done by undervaluing inventories, treating capital expenditure as revenue expenditure, or making excessive provisions for doubtful debts.
A specific way to create a secret reserve is by charging higher depreciation than required. When the total depreciation charged exceeds the total depreciable cost of the asset, the asset's value is understated, creating a hidden cushion.
The purpose of a secret reserve is to hide exceptionally high profits from competitors or to provide a 'cushion' during lean years. While it can be justified on grounds of prudence, it violates the principle of 'full disclosure' and can lead to misleading financial statements.
