Diminishing Balance Method of Depreciation | Example |

Diminishing Balance Method Depreciation Feature image

In Diminishing Balance method, we have calculated the depreciation on the closing value of an asset and charge until the book value of an asset will equal to its scrap value. The amount of depreciation will be diminished or decreased as compared to last year because we charge the fixed rate of depreciation on the closing value of an asset.

It is also called written down value and reducing value method.

This method is suitable for tangible assets like Building, plant & machinery and furniture & fixture etc.

The Depreciation can be calculated under this method with the help of following formula:

Depreciation Formula of written down value  - Diminishing Balance Method of Depreciation | Example |

Example: On 01/04/2017 Machinery purchased for Rs 11,00,000/- and paid for transportation charge 1,50,000/- to install the machine in our plant and paid installation charges also for Rs 50,000/-. The rate of Depreciation @ 10% Year ending 31 March.

So, Total Cost of an asset  = 11,00,000+1,50,000+50,000 

      = Rs 13,00,000/- 

The following table shows the year by year depreciation charged under Diminishing Balance Method.
