A 60 000 asset will be depreciated by the straightline metho
A $60 000 asset will be depreciated by the straight-line method over a six-year period. NO salvage value is expected. If the company\'s tax rate is 50°h, what would be the present-worth advantage of using the sum-of-years7 -digits method, given a 10% after-tax MARR?
Solution
Useful life of asset = 6 Years
Sum of years digits = 6 + 5 + 4 + 3 + 2 + 1 = 21
Depreciation amount for each year = (A) * (B)
| Year | Depreciable amount (A) | Depreciation base (B) | Depreciation amount for each year = (A) * (B) |
| 1 | 60000 | 6/21 | 17143 |
| 2 | 60000 | 5/21 | 14286 |
| 3 | 60000 | 4/21 | 11428 |
| 4 | 60000 | 3/21 | 8572 |
| 5 | 60000 | 2/21 | 5714 |
| 6 | 60000 | 1/21 | 2857 |
| Total | 60000 |
