Generally, if we uses straight line method, then depreciation amount.
So, here we are going to throw light on the difference between slm and wdv methods. The wdv is best determined through the diminishing or depreciating balance method as it is more realistic and accurate compared to the slm which assumes a constant depreciation value per year. Conversely, in written down value method wdv, there is a fixed rate of depreciation which is applied to the opening balance of the asset every year.
