The various methods of depreciation are based on a formula. This formula is derived from the study of the behavior of the assets over a period of time. One such method of depreciation is the Diminishing Balance Method. Let us learn more about this method.
Diminishing Balance Method
According to the Diminishing Balance Method, depreciation is charged at a fixed percentage on the book value of the asset. As the book value reduces every year, it is also known as the Reducing Balance Method or Written-down Value Method.
Since the book value reduces every year, hence the amount of depreciation also reduces every year. Under this method, the value of the asset never reduces to zero.
When the amount of depreciation charged under this method and the corresponding period are plotted on a graph it results in a line moving downwards.
This method is based on the assumption that in the earlier years the cost of repairs to the assets is low and hence more amount of depreciation should be charged. Also, in the later years, the cost of repairs will increase and therefore less amount of depreciation shall be provided. Hence, this method results in an equal burden on the profit every year during the life of the asset.
However, under this method, if the rate of depreciation applied is not appropriate it may happen that at the end of the useful life of the asset full depreciation is not provided.
Also, while applying this method, the period of use of the asset should be considered. If an asset is used only for 2 months in a year then depreciation will be charged only for 2 months.
However, for the Income Tax purposes, if an asset is used for more than 180 days full yearsâ€™ depreciation will be charged. Income Tax Rules also allow depreciation charged on Diminishing Balance Method.
Formulae are as follows:
$$ \text{Amount of depreciation} = \frac{ \text{Book Value} \times \text{Rate of Depreciation} }{100} $$

Working Notes:
Calculation of amount of depreciation
$$ \text{Amount of depreciation} = \frac{ \text{Book Value} \times \text{Rate of Depreciation} }{100} $$
- 2015: Depreciation =Â 500000 x 10/100 Â x 9/12 = Â 37500
- 2016: Depreciation =Â 462500 x 10/100 = 46250
- 2017: Depreciation =Â 416250 x 10/100 = 41625
- 2018: Depreciation =Â Â 374625 x 10/100 x 3/12 =Â 9366
Calculation of loss on sale of machinery
Loss = Book Value on 1 Jan 2018 â€“ depreciation for 3 months â€“ cash received
=Â 374625 â€“ 9366- 250000 = 115259
