# Difference between SLM and WDV

SLM and WDV are two popular methods of determining depreciation (which is the technique for writing off the value of an asset during its useful life time). SLM is also known as the Straight Line Method and in this method depreciation is charged evenly across each accounting period. In other words, we can say that the same amount of money is depreciated each year from the value of the assets in this method.

In the WDV or Written Down Value Method, a fixed percentage of the reducing balance is depreciated from the value of the assets, which results in the asset being reduced to its residual value at the end of its useful life. Here, the initial depreciation charged is higher and the following depreciations charged are lesser.

Let us look at some of the points of difference between the two methods Straight Line Method (SLM) and Written Down Value Method (WDV)
