Straight line method dep:
| Cost | 30,000 |
| Life | 10 years |
| Salvage value | $5,000 |
| Depreciable value | Cost- Salvage Value |
| 30000-5000 | |
| $25,000 | |
| SL method dep= | Depreciable value/life |
| 25000/10 | |
| $2,500 |
Therefore, every year same dep of $2,500 will be charged till the book value reaches salvage value
| Opening cost | SL dep per annum | Closing cost | |
| 2013 | 30,000 | 2,500 | 27,500 |
| 2014 | 27,500 | 2,500 | 25,000 |
| 2015 | 25,000 | 2,500 | 22,500 |
| 2016 | 22,500 | 2,500 | 20,000 |
| 2017 | 20,000 | 2,500 | 17,500 |
| 2018 | 17,500 | 2,500 | 15,000 |
| 2019 | 15,000 | 2,500 | 12,500 |
| 2020 | 12,500 | 2,500 | 10,000 |
| 2021 | 10,000 | 2,500 | 7,500 |
| 2022 | 7,500 | 2,500 | 5,000 |
Double declining balance method
| Cost | 30,000 |
| Life | 10 years |
| Salvage value | $5,000 |
Under DDB, dep is charged at double the rate of SL method dep
| SL method depreciation rate | 1/10 |
| 0.1 | |
| 10% | |
| DDB rate | 10*2 |
| 20% |
Therefore, every year 20% of opening balance of machine will be charged as dep until the book value reaches salvage value.
| Opening cost | Dep percent | Dep expense | Closing cost | |
| 2013 | 30,000 | 20% | 6,000 | 24,000 |
| 2014 | 24,000 | 20% | 4,800 | 19,200 |
| 2015 | 19,200 | 20% | 3,840 | 15,360 |
| 2016 | 15,360 | 20% | 3,072 | 12,288 |
| 2017 | 12,288 | 20% | 2,458 | 9,830 |
| 2018 | 9,830 | 20% | 1,966 | 7,864 |
| 2019 | 7,864 | 20% | 1,573 | 6,291 |
| 2020 | 6,291 | 20% | 1,258 | 5,033 |
| 2021 | 5,033 | 0.66% | 33 | 5,000 |
In the year 2021, dep expense will be charged only for $33 (salvage value- opening book value) as book value of machine cannot be depreciated beyond salvage value.
Units of production method:
| Cost | 30,000 |
| Estimated total production | 45,000 units |
| Salvage value | $5,000 |
| Depreciable Value | 30000-5000 |
| $25,000 |
Under units of production method, dep is charged based on the estimated total production during the life of the machine and units produced every year
| Depreciation per unit of production | depreciable value/total units production | |
| 25000/45000 | ||
| 0.56 |
Therefore dep per annum= total units produced in that year*per unit dep
| Opening cost | Units produced | Dep per unit | Dep expense | Closing cost | |
| 2013 | 30,000 | 4000 | 0.56 | 2,240 | 27,760 |
| 2014 | 27,760 | 3000 | 0.56 | 1,680 | 26,080 |
| 2015 | 26,080 | 5000 | 0.56 | 2,800 | 23,280 |
| 2016 | 23,280 | 4000 | 0.56 | 2,240 | 21,040 |
| 2017 | 21,040 | 5000 | 0.56 | 2,800 | 18,240 |
| 2018 | 18,240 | 6000 | 0.56 | 3,360 | 14,880 |
| 2019 | 14,880 | 5000 | 0.56 | 2,800 | 12,080 |
| 2020 | 12,080 | 6000 | 0.56 | 3,360 | 8,720 |
| 2021 | 8,720 | 4000 | 0.56 | 2,240 | 6,480 |
| 2022 | 6,480 | 3000 | 0.49 | 1,480 | 5,000 |
| 45000 |
In the year 2022, $1,480 (opening book value- salvage value) dep will be charged as an asset cannot be depreciated beyond its salvage value.
