Answer:
Given
Cost $46000
Life= 5 years
Salvage Value= $ 4000
Total miles = 165,000
Formula
Depreciation Straight Line Method= Cost - Salvage Value/ Useful Life
Straight Line Rate= 100%/ useful Life= 100%/5 = 20%
Double Declining Method = 2 * Straight Line Rate
Double Declining Method = 2 * Straight Line Rate= 2*20%= 40%
1.
Depreciation Straight Line Method= Cost - Salvage Value/ Useful Life
Depreciation Straight Line Method= $ 46000- $4000/ 5= $ 8,400
The depreciation expense using the straight line method does not change unless the salvage value is reached
Years Depreciation Accumulated Dep Book Value
(Cost - Accu. Dep)
a. 2021 $ 8,4000 8400 37600
b. 2022 $ 8,4000 16,800 29,200
c. 2023 $ 8,4000 25200 20,800
d. 2024 $ 8,4000 33,600 12,400
e. 2025 $ 8,4000 42000 4000
2. Straight Line Rate= 100%/ useful Life= 100%/5 = 20%
Double Declining Method = 2 * Straight Line Rate
Double Declining Method = 2 * Straight Line Rate= 2*20%= 40%
In double declining method the rate is multiplied to the cost to get the depreciation expense. 40 % of $ 46000= $ 18400
Each year the rate is multiplied with the remaining book value after deducting the depreciation expense from the cost as $ 46000- $ 18400= $ 27600
Next years depreciation will be $ 27600 * 40%= $ 11040.
This will be added in the original depreciation expense $ 18400 + $ 11040 = $ 29440 and deducted from cost to get the book value. $ 46,000- $ 29440 = $ 16560.
Again rate will be multiplied and each years depreciation will be calculated similarly.
It has been summarized in the table below.
Years Dep Rate Dep Expense Accu. Dep. Book Value
a. 2021 40% 18400 18400 27600
b. 2022 40% 11040 29440 16560
c. 2023 40% 6624 36064 9936
d. 2024 40% 3974.4 40,038.4 5961.6
e. 2025 40% 2384.64 42,0423.4 3576.96
3. Depreciation per unit= (Cost -Salvage value) / Total units of production* Units of Production
Years Mileage Depreciation Depreciation
a. 2021 35,000 ($ 42000/165000)*35000 8909.09
b. 2022 37,000 ($ 42000/165000)*37000 9418.18
c. 2023 28,000 ($ 42000/165000)*28000 7127.27
d. 2024 33,000 ($ 42000/165000)*33000 8400
e. 2025 34,000 ($ 42000/165000)*34000 8654.54
