The three most common depreciation methods are: straight line, double-declining, and units of production. We will calculate the depreciation expense for each.
Straight line method:
Depreciable amount= cost - residual value
= 240,000 - 40,000
= 200,000
Depreciation by year = depreciable amount / years of useful life
= 200,000 / 8
= 25,000
Double declining method
Depreciation per year = depreciable amount x (2 / useful life in years)
= 200,000 x (2 / 8)
= 50,000
Units of production method
Depreciation per unit = depreciable amount / hours of operation
= 200,000 / 12,000
= 16.7
Total depreciation = depreciation per unit x actual units of operation
= 16.7 x 2,400 + 2,200
= 16.7 x 4,600
= 76.820
Therefore, the units of production method results in the highest depreciation expense among the three.
