Depreciation is needed for the following reasons:
1. Determining actual profit or loss: Actual profit and loss can be determined only when all expenditures and losses are added to P & L Account. Assets in business are used to earn revenues; the corresponding cost gets charged as depreciation in P & L Account (Profit & Loss Account).
2. Provide an unbiased view of financial statements: Assets will be shown at inflated values when depreciation does not get charged, so it will lead to the balance sheet not showing a fair view of the financial statements.
3. Cost of production: Production cost includes the depreciation charged on machinery and plant, and other similar assets. When depreciation is not charged, production costs will be uneven, which will reduce the profit.
4. Distribution of dividend from profit: If no depreciation is charged, then overestimation of profit takes place, which causes profit to be distributed as dividends. It results in the movement of capital away from the business.
5. Funds used for asset replacement: Depreciation charged for assets will help in meeting the expense for replacing the asset in future.
6. Tax consideration: The P & L account will reflect less profit if depreciation is charged, which results in paying less taxes for the business.
