Scenario: Cost = Useful Life (Years) = Useful Life (Hours) = Salvage Value =
a) Calculate the SL annual rate:
30,000 5 140,000 2,000
1) Depreciable Cost = Cost - Salvage ValueDepreciable Cost = -
2) Calculate the Double DB rate:
SL Rate
x2 -
= Double DB rate
b) Calculate depreciation expense, accumulated depreciation and book value for the life of the
asset.

Solution
Depreciation methods –
a. Calculation the SL annual rate:
Depreciation expense = depreciable base x SL rate
Cost = $30,000
Useful life = 5 years
SL annual rate = 1/5 = 20%
Depreciable base = cost – salvage value
Salvage value = $2,000
Depreciable base = 30,000 – 2,000 = $28,000
Annual depreciation expense = 28,000 x 20% = $5,600

b. Double DB rate –
Double DB rate = 2 x SL rate
= 2 x 20% = 40%
Depreciation expense, year 2010 = 30,000 x 40% = $12,000
Book value = cost – accumulated depreciation
BV at EOY 2010 = 30,000 – 12,000 = $18,000
2011
Depreciation = 18,000 x 40% = 7,200
Accumulated depreciation = 12,000 + 7,200 = 19,200
Book value = 30,000 – 19,200 = 10,800
2012
Depreciation = 10,800 x 40% = $4,320
Accumulated depreciation = 12,000 + 7,200 + 4,320 = $23,520
Book value = 30,000 – 23,520 = $6,480
2013
Depreciation = 6,480 x 40% = $2,592
Accumulated depreciation = 12,000 + 7,200 + 4,320 + 2,592 = $26,112
Book value = 30,000 – 26,112 = $3,888
2014
Depreciation = 3,888 x 40% = $1,555
Accumulated depreciation = 12,000 + 7,200 + 4,320 + 1,555 = $27,667
BV = 30,000 – 27,667 = $2,333

Units-of-activity rate –
Depreciation expense = (depreciable base/useful life in hours) x hours used
Depreciable base = 30,000 – 2,000 = $28,000
Depreciation rate = 28,000/140,000 = $0.20 per hour
Depreciation expense = depreciation rate x units/hours
