The completion of separate depreciation schedules for each of the alternative depreciation methods is as follows:
a. Straight-line Method:
Year Cost Annual Depreciation Accumulated Net Book
Depreciation Value
Year 1 $20,000 $4,455 $4,455 $15,545
Year 2 $20,000 $4,455 8,910 11,090
Year 3 $20,000 $4,455 13,365 6,535
Year 4 $20,000 $4,455 17,820 2,180
b. Units-of-production Method:
Year Cost Annual Depreciation Accumulated Net Book
Depreciation Value
Year 1 $20,000 $7,128 $7,128 $12,872
Year 2 $20,000 $5,346 12,474 7,526
Year 3 $20,000 $3,564 16,038 3,962
Year 4 $20,000 $1,782 17,820 2,180
c. Double-declining-balance Method:
Year Cost Annual Depreciation Accumulated Net Book
Depreciation Value
Year 1 $20,000 $10,000 $10,000 $10,000
Year 2 $20,000 $5,000 15,000 5,000
Year 3 $20,000 $2,500 17,500 2,500
Year 4 $20,000 $320 17,820 2,180
Data and Calculations:
Cost of asset = $20,000
Residual value = $2,180
Depreciable amount = $17,820 ($20,000 - $2,180)
Estimated productive life = 4 years or 9,900 hours
Annual depreciation rates:
Straight-line method = $4,455 ($17,820/4)
Units-of-production Method per unit = $1.8 ($17,820/9,900)
Double-declining-balance Method rate = 50% (100/4 x 2)
