The vehicle is expected to have a 8-year useful life, and a salvage value of $28,000 at the end of its useful life.
In mileage, the rig has an expected life of 352,000 miles.
The rig was driven 44,500 miles in 2020 and 41,840 miles in 2021.

Using the above data, determine depreciation expense for the years 2020 and 2021 under each of the following methods: (6 answers in all)

a) Straight-Line

b) Units-of-Production

c) Declining balance at twice the straight-line rate (Double-Declining Balance)

a

Explanation:

Cost of Trailer - $188,000

Salvage value $28,000

Useful life: 8 years

Depreciable amount - $160,000

Expected miles coverage - 352,000

Mileage in 2020 = 44,500

Mileage in 2021 = 41480

Depreciation rate = 1/8*100 = 12.5%

Straight line :

160,000/8 = 20,000                     2020                      2021

                                                     20000                     20000

Units of production   (44500/352000*160000) (41480/352000*160000)

                                                   20,227.27                      18,854.54

Double declining                   25%*188000            25%*141000

balance                                        47000                      35250
