The depreciation expense for the first two years using the 150% declining-balance rate is $21,500 and $19,350, and using the 200% declining-balance rate is $28,666.67 and $20,523.81.
To compare the two alternative depreciation rates (150% and 200% declining-balance) for the equipment purchased by Spence, Incorporated, we can use the following formula for declining-balance depreciation:
Depreciation Expense=Beginning Book Value×Declining-Balance Rate
The declining-balance rate is a multiple of the straight-line rate. For the 150% rate, it's 1.5 times the straight-line rate, and for the 200% rate, it's 2 times the straight-line rate.
Given that the equipment cost $86,000 and has an estimated useful life of 8 years with no salvage value, the straight-line rate is 1/8 or 12.5%.
For the 150% declining-balance rate:
Depreciation Expense Year 1=86,000×1.5×12.5%
Depreciation Expense Year 2=(Beginning Book Value Year 1−Depreciation Expense Year 1)×1.5×12.5%
For the 200% declining-balance rate:
Depreciation Expense Year 1=86,000×2×12.5%
Depreciation Expense Year 2=(Beginning Book Value Year 1−Depreciation Expense Year 1)×2×12.5%
Calculating these values gives us the depreciation expenses for the first two years under both rates, which are $21,500 and $19,350 for the 150% rate, and $28,666.67 and $20,523.81 for the 200% rate. These values can then be presented in a comparison for management decision-making.
