An asset costs $10,000 and has a depreciable life of 10 years and a salvage value of $3,000. Determine the book (asset) value at the end of the 9th year using each of the following methods of depreciation (a) double-declining-balance method (b) textbook-declining-balance method (Matheson formula), and (c) sum-of-years’ digits method.
(a) Double Declining Balance method Depreciation = Beginning Book Value x 2 times straight line rate
Maximum Depreciation is such that ending book value doesnot fall below salvage value
YEAR | Beginning Book Value | Depreciation Sum of Digits@20% | Accumulated Depreciation | Ending Book Value |
---|---|---|---|---|
1 | $ 10,000 | $ 2,000 | $ 2,000 | $ 8,000 |
2 | $ 8,000 | $ 1,600 | $ 3,600 | $ 6,400 |
3 | $ 6,400 | $ 1,280 | $ 4,880 | $ 5,120 |
4 | $ 5,120 | $ 1,024 | $ 5,904 | $ 4,096 |
5 | $ 4,096 | $ 819 | $ 6,723 | $ 3,277 |
6 | $ 3,277 | $ 277 | $ 7,000 | $ 3,000 |
7 | $ 3,000 | $ - | $ 7,000 | $ 3,000 |
8 | $ 3,000 | $ - | $ 7,000 | $ 3,000 |
9 | $ 3,000 | $ - | $ 7,000 | $ 3,000 |
10 | $ 3,000 | $ - | $ 7,000 | $ 3,000 |
Book Value at end of 9th year = $3000
(b) Textbook Declining Balance Method = Beginning Book Value x Depreciation rate
YEAR | Beginning Book Value | Depreciation Sum of Digits @10% | Accumulated Depreciation | Ending Book Value |
---|---|---|---|---|
1 | $ 10,000 | $ 1,000 | $ 1,000 | $ 9,000 |
2 | $ 9,000 | $ 900 | $ 1,900 | $ 8,100 |
3 | $ 8,100 | $ 810 | $ 2,710 | $ 7,290 |
4 | $ 7,290 | $ 729 | $ 3,439 | $ 6,561 |
5 | $ 6,561 | $ 656 | $ 4,095 | $ 5,905 |
6 | $ 5,905 | $ 590 | $ 4,686 | $ 5,314 |
7 | $ 5,314 | $ 531 | $ 5,217 | $ 4,783 |
8 | $ 4,783 | $ 478 | $ 5,695 | $ 4,305 |
9 | $ 4,305 | $ 430 | $ 6,126 | $ 3,874 |
10 | $ 3,874 | $ 387 | $ 6,513 | $ 3,487 |
Book Value at end of 9th year = $3874
(c) Sum of Year's Digit Method = (Original Value - Salvage Value) / Sum of Years x Years remaining
YEAR | Beginning Book Value Depreciation Sum of Digits | Depreciation Sum of Digits | Accumulated Depreciation | |
---|---|---|---|---|
1 | $ 10,000 | $ 1,273 | $ 1,273 | $ 8,727 |
2 | $ 8,727 | $ 1,145 | $ 2,418 | $ 7,582 |
3 | $ 7,582 | $ 1,018 | $ 3,436 | $ 6,564 |
4 | $ 6,564 | $ 891 | $ 4,327 | $ 5,673 |
5 | $ 5,673 | $ 764 | $ 5,091 | $ 4,909 |
6 | $ 49,09 | $ 636 | $ 5,727 | $ 4,273 |
7 | $ 4,273 | $ 509 | $ 6,236 | $ 3,764 |
8 | $ 3, 764 | $ 382 | $ 6,618 | $ 3,382 |
9 | $ 3,382 | $ 255 | $ 6873 | $ 3,127 |
10 | $ 3,127 | $ 127 | $ 7,000 | $ 3,000 |
Book Value at end of 9th year = $3127.
