Concept And Meaning Of Annuity Method Of Providing Depreciation
Under this method, it is assumed that the amount spent in the purchase of the assets is an investment which should earn interest. The amount spent in acquiring an asset is assumed as an investment and interest is charged at a certain rate on the diminishing balance of assets and is debited to assets account and credited to interest account which is transferred to profit and loss account. The asset is credited year by years with a fixed amount of depreciation. The amount of depreciation charged every year is such that in spite of asset being debited with interest every year, the asset is reduced to zero or its residual value. The amount of depreciation is calculated on the basis of annuity table.
When additions are made to asset account, calculations have to be revised. This method is used in the case of leases having large amount spread over a number of years.
