Answer:
a. Under straight-line method, annual depreciation expenses are as follows:
Year Annual depreciation expense ($)
2022 61,300
2023 61,300
2024 61,300
2025 61,300
b. Under the declining-balance method using double the straight-line rate, annual depreciation expenses are as follows:
Year Annual depreciation expense ($)
2022 139,000
2023 69,500
2024 34,750
2025 1,950
Explanation:
a. Prepare a separate depreciation schedule for the machinery using the straight-line method.
Note: See part a of the attached excel file for the depreciation schedule for Straight-line method.
In the attached excel file, the depreciation rate used for the Straight-line method is calculated as follows:
Straight line depreciation rate = 1 / Estimated useful life = 1 / 4 = 0.25, or 25%
From part a of the attached excel file, we have:
Year Annual depreciation expense ($)
2022 61,300
2023 61,300
2024 61,300
2025 61,300
b. Prepare a separate depreciation schedule for the machinery using the declining-balance method using double the straight-line rate.
Note: See part b of the attached excel file for the depreciation schedule for double-declining-balance method.
In the attached excel file, the depreciation rate used for the Double declining-balance method is calculated as follows:
Double-declining depreciation rate = Straight line depreciation rate * 2 = 25% * 2 = 50%
From part b of the attached excel file, we have:
Year Annual depreciation expense ($)
2022 139,000
2023 69,500
2024 34,750
2025 1,950
Note:
Under this double-declining-balance method, the depreciation expenses for 2025 is calculated by deducting the salvage value of $32,800 from the 2025 Beginning depreciable amount (i.e. $34,750 - $32,800 = $1,950). The residual value of $32,800 therefore represents the book value on December 31, 2025.
