A naval shipyard just purchased $800,000 in capital equipment for ship repairing functions on dry-docked ships. Estimated salvage is $150,000 for any year after 5 years of use. Compare the depreciation and book value for year 3 for each of the following depreciation methods. a. MACRS where a recovery period of 10 years is allowed b. DDB with a recovery period of 15 years c. S-L as an alternative to MACRS, with a recovery period of 15 years
| MACRS | ||||
| Year | Opening balance | Depreciation | Closing balance | |
| 1 | $ 8,00,000.00 | $ 80,000.00 | =800000*10% | $ 7,20,000.00 | 
| 2 | $ 7,20,000.00 | $ 1,44,000.00 | =800000*18% | $ 5,76,000.00 | 
| 3 | $ 5,76,000.00 | $ 1,15,200.00 | =800000*14.4% | $ 4,60,800.00 | 
| Straight line method | ||||
| Year | Opening balance | Depreciation | Closing balance | |
| 0 | $ 8,00,000.00 | $ 8,00,000.00 | ||
| 1 | $ 8,00,000.00 | $ 43,333.33 | =(800000-150000)/15 | $ 7,56,666.67 | 
| 2 | $ 7,56,666.67 | $ 43,333.33 | =(800000-150000)/15 | $ 7,13,333.33 | 
| 3 | $ 7,13,333.33 | $ 43,333.33 | =(800000-150000)/15 | $ 6,70,000.00 | 
Depreciation = Investment/Life
| Double declining balance | ||||
| Year | Opening balance | Depreciation | Closing balance | |
| 0 | $ 8,00,000.00 | $ 8,00,000.00 | ||
| 1 | $ 8,00,000.00 | $ 1,06,640.00 | =800000*13.33% | $ 6,93,360.00 | 
| 2 | $ 6,93,360.00 | $ 92,424.89 | =693360*13.33% | $ 6,00,935.11 | 
| 3 | $ 6,00,935.11 | $ 80,104.65 | =600935*13.33% | $ 5,20,830.46 | 
the SLM rate = 1/15 or 6.667% so the DDB rate = 13.33%
DDB depreciation = Opening balance x depreciation rate
Amount of depreciation expense in year 3 is highest and book value at year 3 is lowest in MACRS Depreciation method.
