Accelerated depreciation is a method to calculate the book value of a fixed asset over the years. In this method, the relative asset incurred higher expenses than last remaining years, unlike straight-line method.
There are two methods two calculate accelerated depreciation i.e. double declining balance method and Sum of the years’ digits method.
Double declining balance method formula
Annual Depreciation Expenses = Net Book Value x 2/Useful life in years
Sum of the years’ digits method formula
Depreciation Expense = Remaining useful life of asset / Sum of the years digits x Depreciable Cost
