The straight Line method has the following advantages: 1. It is very simple, easy to understand, and apply. Simplicity makes it a popular method in practice; 2. Asset can be depreciated up to the net scrap value or zero value. Therefore, this method makes it possible to distribute the full depreciable cost over the useful life of the asset; 3. Every year, the same amount is charged as depreciation in the profit and loss accounts. This makes a comparison of profits for different years easy;  4. This method is suitable for those assets whose useful life can be estimated accurately and where the use of the asset is consistent from year to year such as leasehold buildings.
