Answer:
Straight-line method
December 31, 2012: $9,450 x 3/12 = $2,362.5
December 31, 2013: $9,450
December 31, 2014: $9,450
December 31, 2015: $9,450 x 9/12 = $7,087.5
Unit-of-production method:
December 31, 2012: 700 hours x 7.5* = $5,250
December 31, 2013: 1,300 hours x 7.5 = $9,750
December 31, 2014: 1,100 hours x 7.5 = $8,250
December 31, 2015: 680 hours x 7.5 = $5,100
7.5*: ($29,160 - $810) / 3,780 operating hours
Double declining method:
December 31, 2012: $29,160 x 2/3 x 3/12= $4,860
December 31, 2013: ($29,160 - $4,860) x 2/3 = $16,200
December 31, 2014: ($29,160 - $4,860 - $16,200) x 2/3 = $5,400
December 31, 2015: ($29,160 - $4,860 - $16,200 - $5,400) x 2/3 x 9/12 = $1,350
Step-by-step explanation:
Requirement of the question: Determine the amount of depreciation expense for the years ended December 31, 2012, 2013, 2014, and 2015, by (a) the straight-line method, (b) the units-of-output method, and (c) the double-declining-balance method.
(a) Under straight-line method, depreciation expense is (cost - residual value) / No of years = ($29,160 - $810) / 3 years = $9,450 yearly depreciation expense.
(b)The unit-of-production method is used when the asset value closely relates to the units of output it is able to produce. It is expressed with the formula below:
(Original Cost - Salvage value) / Estimated production capacity x Units/year
(c) The double-declining method is otherwise known as the reducing balance method and is given by the formula below:
Double declining method = 2 X SLDP X BV
SLDP = straight-line depreciation percentage
BV = Book value
SLDP is 100%/3 years = 33.33%, then 33.33% multiplied by 2 to give 66.67% or simply 2/3
