Final answer:
The depreciation expense for a stamping machine under the straight-line method is calculated as $22,500 per year. For units-of-production and working-hours methods, it is $2,125 and $1,837.50 for 2016, respectively. The double-declining-balance method cannot be calculated without additional data on the machine's previous depreciation and book value.
Step-by-step explanation:
The question involves calculating the depreciation expense for a stamping machine for the year 2016 under different methods. Each method uses a different basis to allocate the machine's cost over its useful life. The methods include the straight-line method, units-of-production, working-hours, and double-declining-balance with and without conversion to straight line.
To calculate depreciation using the straight-line method, subtract the salvage value from the cost of the machine, and divide that amount by the useful life. For the stamping machine:
- Depreciation expense = (Cost - Salvage value) / Useful life
- Depreciation expense = ($257,000 - $32,000) / 10
- Depreciation expense = $22,500 per year
Units-of-Production
This method allocates the cost of the machine based on the number of units produced.
Depreciation expense = (Cost - Salvage value) / Total units expected to be produced during entire useful life * Number of units produced in 2016
Depreciation expense = ($257,000 - $32,000) / 250,000 * 23,450
Depreciation expense = $22,500 * (23,450 / 250,000)
Depreciation expense = $2,125
Working-Hours Method
Similar to the units-of-production, with the basis being the number of working hours instead of units:
Depreciation expense = (Cost - Salvage value) / Total working hours expected * Number of hours machine worked in 2016
Depreciation expense = ($257,000 - $32,000) / 30,000 * 2,450
Depreciation expense = $22,500 * (2,450 / 30,000)
Depreciation expense = $1,837.50
Double-Declining-Balance
The double-declining-balance without converting to straight line and with conversion will require information on the machine's previous depreciation and book value which has not been provided; hence, the calculations for 2016 cannot be completed without additional data.
