Sinking Fund Method

Sinking fund method is a method of calculating depreciation for an asset in which apart from calculating depreciation, it also keeps aside a fund for replacing the asset at the end of its useful life.

This method is used when the assets that need to be replaced are of high cost. To avoid paying for the replacement of assets at a time, companies maintain a sinking fund that will help them recover the cost of the asset while also accounting for its depreciation.

Sinking fund method is put into use by large scale industries such as utility industries that have a requirement for expensive long-term assets to function.

How Sinking Fund Functions

Sinking fund functions as an account where the company stores funds in anticipation that it will become dysfunctional after a certain point of time. Instead of expenditure that will arise at a time which can cause a significant impact on company’s profit, it is better that such an expense can be anticipated and the funds for replacement of such an asset can be made wisely.

Under the sinking fund method, the depreciation that is charged for the asset is transferred to a sinking fund account. The same amount is then invested in securities issued by government, interest that is earned on such securities are reinvested.

The interest that is earned on the amount invested as depreciation will also be invested and will be invested to the extent of useful life of the asset. When the asset needs replacement, the investment which is done in the form of securities are sold and the asset will be purchased from the amount thus obtained.

Also, the old assets book value will be deposited to the Sinking fund account. The value obtained by selling of old asset which can be either profit or loss are then moved to the Sinking Fund Account.

The balance of the sinking fund account is then further transferred to General Reserve. The sinking fund account is also known as depreciation fund account.
