A machine that cost SAR 320,000 is owned by a cement factory.
Salvage is estimated at SAR 75,000.
Compare book values for MACRS, DB (20%), DDB and standard SL
depreciation over a 7-year recovery
period.

SL depreciation expense per year = $ 35,000
The book value of the machine over the useful life of the asset is calculated as follows

Double declining rate = 40%
| Double declining balance depreciation method | ||||
| Year | Book value at the beginning of the year | Depreciation rate per year | Depreciation | Book value at the end of the year |
| 1 | 320000 | 40.00% | 128000 | 192,000 |
| 2 | 192,000 | 40.00% | 76800 | 115,200 |
| 3 | 115,200 | 40.00% | 46080 | 69,120 |
