This article proposes a new time-based depreciation method using the accumulated depreciation rate function. The method can systematically compute the depreciation charge of each period, in every case where the charge is constant or decreasing or increasing, and solve the problems of depreciation methods currently used, by obtaining the accumulated depreciation charge at any given time. We can choose diverse rational depreciation types for the characteristic of every asset with the new method, and compute the depreciation charge with consistency in all cases where assets are owned for partial period.

This article presents detailed explanations of the depreciation method using the accumulated depreciation rate function(ADRF) proposed by the author previously, for the practical application. ADRF provides a value of accumulated depreciation rate on the total depreciation charge at any given time, therefore it can be used in a time-based depreciation method. Since the depreciation charge of each period can be systematically computed with ADRF, in every case where the charge is constant or decreasing or increasing, we can choose diverse rational depreciation types for the characteristic of every asset. Also, since the ADRF is the continuous function of time, we can compute the depreciation charge with consistency in cases where assets are owned for partial period. However, we should determine the value of parameter of ADRF. We give some data on the problem.
