Depreciation

main purpose

Depreciation is an allowance or provision made in the financial records of a business or association for "wear and tear" and "technical obsolescence ". The idea of depreciation is to spread the cost of that capital asset over the period of its "useful life to the entity" that currently owns it. If the full cost of the asset were to be borne in the year that it was purchased, then that year's expenditure would be unfairly penalised whilst expenditure during the remaining years, which were still receiving the benefit from the asset, would not be affected.

agree with Ms.Kavitha

other than that,,the company would be able to create a provision for depreciation which would act as a support while buying a new asset at a later point of time.
