On January 2, 2015, Alvarez Company purchased an electroplating machine to help manufacture a part for one of its key products. The machine cost $250,500 and was estimated to have a useful life of six years or 700,000 cuttings, after which it could be sold for $25,500.

Required
Calculate each year’s depreciation expense for the period 2015-2020 under each of the following depreciation methods:

a. Straight-line.
b. Double-declining balance.
c. Units-of-production.

Straight line for 2015-2020= $37,500 each year

Double Declining 2015 = $83,500, other years are explained

Untis of production 2015= $45,000.2, other years are in the explanation.

Explanation:

The completion of the question is as follows

FOr Units of Production,  (Assume annual production in platings of 140,000; 180,000; 100,000; 110,000; 80,000; and 90,000.)

The question is to determine and compute the depreciation expense for 2015-2020 as follows

a) Straight line method

Formula = Cost of Equipment - The residual value / useful life of the equipment

= $250,500- $25,500 / 6 years

= $37,500

Year 2015 = $37,500

Year 2016 = $37,500

Year 2017 = $37,500

Year 2018 = $37,500

Year 2019 = $37,500

Year 2020 = $37,500

b) Double Declining Balance

Formula = The straight line method rate x 2 x The net book value of the machine

= 1/6 x 2 x $250,500

2015= $83,500

2016 = 1/6 x 2 x $250,500- $83,500 = $55,666.67

following the same process of getting the book value for each year, subtract the depreciation from the book vaule for the next year

2017= 31,111.11

2018= 24,740.74

2019= 16,493..83

2020= 7,487.65

c)The unit of productio method

First we get the unit cost = The Cost of the machine - its salvage value/ the number of cuttings

= $250500-$25500 / 700,000 cuttings = 0.32143

Year 2015 = 0.32143 x 140,000 = 45,000.2

Year 2016 = 0.32143 x 180,000= 57,857.4

Year 2017 = 0.32143 x 100000= 32,413

Year 2018 = 0.32143 x 110,000= 35,357.3

Year 2019 = 0.32143 x 80,000= 25,714.4

Year 2020 = 0.32143 x 90,000= 28,928.7
