Question

The solution for the problem is below. I am wondering why it's multiplied by 2 at the evry end of the solution.

On January 1, 2012, Nobel Corporation acquired machinery at a cost of $1,200,000. Nobel adopted the straight-line method of depreciation for this machine and had been recording depreciation over an estimated life of ten years, with no residual value. At the beginning of 2015, a decision was made to change to the double-declining balance method of depreciation for this machine. The amount that Nobel should record as depreciation expense for 2015 is

{($1,200,000 – [($1,200,000 ÷ 10) × 3]} ÷ 7 × 2 = $240,000

Explanation / Answer

Straight Line Method:

Depreciation P.a = Cost of Asset- Salvage Value/ Life of Asset

                                =$1,200,000-0/10

                                =$120,000

Cost of Asset                                                     $1,200,000

Less: Depreciation for 2012-2014

( 120,000 x 3)                                                      ($360,000)

                                                                     -----------------------------

Beginning cost for 2015 $840,000

Double decline Method:

Revised cost of Asset = $840,000

Salvage value =$0

Remaining life of asset= 7 years

Dep % under straight line method= 1/7=14.285%

Dep % under Double decline method= 2 x Dep % under straight line method= 2 x 14.285%=28.57%

Depreciation for 2015= $840,000 x 28.57%=$ 240,000

As per formula we need to multiply with 2 for double decline
