Total Charge against Profit and Loss Account on Account of Depreciation and Repair Expenses
The repair and maintenance expenses increase in later years of the useful life of the asset. Hence, total charge against profit and loss account in respect of depreciation and repair expenses increases in later years under straight line method. This happens because annual depreciation charge remains fixed while repair expenses increase. On the other hand, under written down value method, depreciation charge declines in later years, therefore total of depreciation and repair charge remains similar or equal year after year.
