Explanation:
a) Data and Calculations:
Cost of new machines = $234,000
Residual value of equipment = $27,000
Depreciable amount = $207,000
Estimated useful life = 6 years
Straight-line depreciation expense per annum = $34,500 ($207,000/6)
Double-declining-balance rate = 33% (100%/6 * 2)
Year Depreciation Declining Balance
1 $77,220 $156,780
2 $51,737 $105,043
3 $34,664 $70,379
4 $23,225 $47,154
5 $15,561 $31,583
6 $4,593 $27,000
Estimated useful life in hours = 12,000
Depreciation rate per hour = $17.25 ($207,000/12,000)
Actual usage per year:
Year Hours Used Usage Charge
1 2,800 $48,300 (2,800 * $17.25)
2 1,900 $32,775 (1,900 * $17.25)
3 2,000 $34,500 (2,000 * $17.25)
4 2,000 $34,500 (2,000 * $17.25)
5 1,800 $31,050 (1,800 * $17.25)
6 1,500 $25,825 (1,500 * $17.25)
