Depreciation cost

What is the 'Depreciated Cost'

1. The value of an asset net of all accumulated depreciation that has been recorded against it. It follows the formula of:

Depreciated Cost = Purchase Price (or cost basis) – {Cumulative Depreciation}

Depreciated cost is also known as the "net book value" or "adjusted cost basis".

2. In a broader economic sense, the depreciated cost for industry is the aggregate amount of capital that is "used up" in a given period, such as a fiscal year. This value can be examined for trends in capital spending and accounting aggressiveness.

Depreciation Methods

GAAP

Depreciation is a systematic and rational process of distributing the cost of tangible assets over the life of assets.      Depreciation is a process of allocation.      Cost to be allocated = acquisition cot - salvage value      Allocated over the estimated useful life of assets.      Allocation method should be systematic and rational.

Depreciation methods based on time            Straight line method            Declining balance method                     Sum-of-the-years'-digits method     Depreciation based on use (activity)

Straight Line Depreciation Method

Depreciation = (Cost - Residual value) / Useful life [Example, Straight line depreciation]         On April 1, 2011, Company A purchased an equipment at the cost of $140,000.  This equipment is estimated to have 5 year useful life.  At the end of the 5th year, the salvage value (residual value) will be $20,000.  Company A recognizes depreciation to the nearest whole month.  Calculate the depreciation expenses for 2011,  2012 and 2013 using straight line depreciation method.         Depreciation for 2011            = ($140,000 - $20,000) x 1/5 x 9/12 = $18,000        Depreciation for 2012            = ($140,000 - $20,000) x 1/5 x 12/12 = $24,000        Depreciation for 2013            = ($140,000 - $20,000) x 1/5 x 12/12 = $24,000

Declining Balance Depreciation Method

Depreciation = Book value x Depreciation rate        Book value = Cost - Accumulated depreciation               Depreciation rate for double declining balance method            = Straight line depreciation rate x 200%        Depreciation rate for 150% declining balance method            = Straight line depreciation rate x 150% [Example, Double declining balance depreciation]         On April 1, 2011, Company A purchased an equipment at the cost of $140,000.  This equipment is estimated to have 5 year useful life.  At the end of the 5th year, the salvage value (residual value) will be $20,000.  Company A recognizes depreciation to the nearest whole month.  Calculate the depreciation expenses for 2011,  2012 and 2013 using double declining balance depreciation method.         Useful life = 5 years  -->  Straight line depreciation rate = 1/5 = 20% per year        Depreciation rate for double declining balance method             = 20% x 200% = 20% x 2 = 40% per year        Depreciation for 2011            = $140,000 x 40% x 9/12 = $42,000        Depreciation for 2012            = ($140,000 - $42,000) x 40% x 12/12 = $39,200        Depreciation for 2013            = ($140,000 - $42,000 - $39,200) x 40% x 12/12 = $23,520      Double Declining Balance Depreciation Method Year Book Value at the beginning Depreciation Rate Depreciation Expense Book Value at the year-end 2011 $140,000 40% $42,000 (*1) $98,000 2012 $98,000 40% $39,200 (*2) $58,800 2013 $58,800 40% $23,520 (*3) $35,280 2014 $35,280 40% $14,112 (*4) $21,168 2015 $21,168 40% $1,168 (*5) $20,000    (*1) $140,000 x 40% x 9/12 = $42,000    (*2) $98,000 x 40% x 12/12 = $39,200    (*3) $58,800 x 40% x 12/12 = $23,520    (*4) $35,280 x 40% x 12/12 = $14,112    (*5) $21,168 x 40% x 12/12 = $8,467            --> Depreciation for 2015 is $1,168 to keep book value same as salvage value.            --> $21,168 - $20,000 = $1,168 (At this point, depreciation stops.)

[Example, 150% declining balance depreciation]          On April 1, 2011, Company A purchased an equipment at the cost of $140,000.  This equipment is estimated to have 5 year useful life.  At the end of the 5th year, the salvage value (residual value) will be $20,000.  Company A recognizes depreciation to the nearest whole month.  Calculate the depreciation expenses for 2011,  2012 and 2013 using double declining balance depreciation method.         Useful life = 5 years  -->  Straight line depreciation rate = 1/5 = 20% per year        Depreciation rate for double declining balance method             = 20% x 150% = 20% x 1.5 = 30% per year        Depreciation for 2011            = $140,000 x 30% x 9/12 = $31,500        Depreciation for 2012            = ($140,000 - $31,500) x 30% x 12/12 = $32,550        Depreciation for 2013            = ($140,000 - $31,500 - $32,550) x 30% x 12/12 = $22,785    150% Declining Balance Depreciation Method   Year Book Value at the beginning Depreciation Rate Depreciation Expense Book Value at the year-end 2011 $140,000 30% $31,500 (*1) $108,500 2012 $108,500 30% $32,550 (*2) $75,950 2013 $75.950 30% $22,785 (*3) $53,165 2014 $53,165 30% $15,950 (*4) $37,216 2015 $37,216 30% $11,165 (*5) $26,051 2016 $26,051 30% $6,051 (*6) $20,000    (*1) $140,000 x 30% x 9/12 = $31,500    (*2) $108,500 x 30% x 12/12 = $32,550    (*3) $75,950 x 30% x 12/12 = $22,785    (*4) $53,165 x 30% x 12/12 = $15,950    (*5) $37,216 x 30% x 12/12 = $11,165    (*6) $26,051 x 30% x 12/12 = $7,815            --> Depreciation for 2016 is $6,051 to keep book value same as salvage value.            --> $26,051 - $20,000 = $6,051 (At this point, depreciation stops.)

Sum-of-the-years'-digits method

Depreciation expense = (Cost - Salvage value) x Fraction          Fraction for the first year = n / (1+2+3+...+ n)          Fraction for the second year = (n-1) / (1+2+3+...+ n)          Fraction for the third year = (n-2) / (1+2+3+...+ n)            ...          Fraction for the last year = 1 / (1+2+3+...+ n)          n represents the number of years for useful life.

[Example, Sum-of-the-years-digits method]   Company A purchased the following asset on January 1, 2011.     What is the amount of depreciation expense for the year ended December 31, 2011?    Acquisition cost of the asset --> $100,000    Useful life of the asset --> 5 years    Residual value (or salvage value) at the end of useful life --> $10,000    Depreciation method --> sum-of-the-years'-digits  method   Calculation of depreciation expense    Sum of the years' digits = 1+2+3+4+5 = 15    Depreciation for 2011 = ($100,000 - $10,000) x 5/15 = $30,000    Depreciation for 2012 = ($100,000 - $10,000) x 4/15 = $24,000    Depreciation for 2013 = ($100,000 - $10,000) x 3/15 = $18,000    Depreciation for 2014 = ($100,000 - $10,000) x 2/15 = $12,000    Depreciation for 2015 = ($100,000 - $10,000) x 1/15 = $6,000       Sum of the years' digits for n years           = 1 + 2 + 3 + ...... + (n-1) + n = (n+1) x (n / 2)       Sum of the years' digits for 500 years           = 1 + 2 + 3 + ...... + 499 + 500           = (500 + 1) x (500 / 2) = (501 x 500) / 2 = 125,250
