Answer:
to calculate depreciation using the sum-of-the-years'-digits method:
n(n+1) divided by 2 = [12(13)] / 2 = 78
depreciable value = cost - salvage value = $469,000 - $40,000 = $429,000
- depreciation year 1 = 12/78 x $429,000 = $66,000
- depreciation year 2 = 11/78 x $429,000 = $60,500
- depreciation year 3 = 10/78 x $429,000 = $55,000
the formula used to calculate depreciation using the double-declining-balance method is:
2 x cost of the asset x depreciation rate
- depreciation year 1 = 2 x $469,000 x 1/12 = $78,167
- depreciation year 2 = 2 x ($469,000 - $78,167) x 1/12 = $65,139
- depreciation year 3 = 2 x ($390,833 - $65,139) x 1/12 = $54,282
Using the sum-of-the-year digits method, the depreciation expense in:
Year 1 = $66,000
Year 2 = $60,500
Year 3 = $55,000
Using the double-declining balance method, the depreciation expense in:
Year 1 = 78,166.67
Year 2 = $65,138.89
Year 3 = $54,282.41
Sum-of-the-year digits = (remaining useful life / sum of the years ) x (Cost of asset - Salvage value)
Sum of the years = 1 +2 +3 +4 + 5 + 6 + 7 + 8 + 9 + 10 + 12 + 11 = 78
Year 1 deprecation
(12 / 78) x ($469,000 - $40,000) = $66,000
Year 2 deprecation
(11 / 78) x ($469,000 - $40,000) = $60,500
Year 3 deprecation
(10 / 78) x ($469,000 - $40,000) = $55,000
Depreciation expense using the double declining method = Depreciation factor x cost of the asset
Depreciation factor = 2 x (1/useful life)
Year 1 deprecation
2/12 x $469,000 = 78,166.67
Book value in year 2 = $469,000 - 78,166.67 = $390,833.33
Year 2 deprecation
2/12 x $390,833.33 = $65,138.89
Book value in year 3 =$390,833.33 - $65,138.89 = $325,694.44
Year 3 deprecation
2/12 x $325,694.44 = $54,282.41
