# Straight Line Method: –

In Straight Line Method, we calculate the fixed amount of depreciation on the original cost of an asset and charge until the book value of an asset will equal to zero or its scrap value.

It is also called the original cost method and fixed cost method.

This method is suitable for intangible assets like patent, copyright, and trademarks etc.

### The formula of Calculated Depreciation: –

The Depreciation can be calculated under the Straight Line Method of Depreciation as shown below:

Total Cost of an asset includes money spent on the purchase of it and to convert it into working condition like installation charges, transportation charges, and first time oiling etc.

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/-. Scrap value will be Rs 1,00,000/- and the useful life of machinery is 20 year. Year ending 31 March. Charge depreciation with the Straight Line Method of depreciation.

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

=Rs 13,00,000/-
