A machine that produces cellphone components is purchased on
A machine that produces cellphone components is purchased on January 1, 2016, for $147,000. It is expected to have a useful life of four years and a residual value of $15,000. The machine is expected to produce a total of 200,000 components during its life, distributed as follows: 40,000 in 2016; 50,000 in 2017; 60,000 in 2018; and 50,000 in 2019. The company has a December 31 year end.
Calculate the amount of depreciation to be charged each year, using each of the following methods:
| i. | Straight-line method | 
Solution
(i) Straight Line Method :-
Depreciation =( Purchased Price – Residual Value)/Useful Life
= (147000 – 15000)/4 years = $ 33000 per yr
(ii) Units of Production Method :-
Total components produce during its life = 200000
Depreciation per unit= (Cost – Salvage value) / Component produced during its entire life
= (147000 – 15000)/200000 = 0.66
2016 (40000 * 0.66)
26400
2017 (50000 * 0.66)
33000
2018 (60000 * 0.66)
39600
2019 (50000 * 0.66)
33000
(iii) Double Diminishing Balance Method :-
Rate = Straight line method rate * 2
Straight line method rate =( 1/life) * 100
= ¼ * 100 = 25%
Double Declining Balance method rate = 25 * 2 = 50%
2016 (147000 * 50%)
73500
2017 (147000 – 73500) * 50%
36750
2018 (147000 – 73500 – 36750) * 50%
18375
2019 (147000 – 73500 – 36750 - 18375) * 50%
9187.5
Which Method Result in Highest Depreciation Expense :-
(i) During the first 2 year = Double Diminishing Balance Method
(ii) Over all 4 years = Double Diminishing Balance Method
| 2016 (40000 * 0.66) | 26400 | 
| 2017 (50000 * 0.66) | 33000 | 
| 2018 (60000 * 0.66) | 39600 | 
| 2019 (50000 * 0.66) | 33000 |
