Question

A machine which cost $400,000 is acquired on January 1, 2017. Its estimated salvage value is $100,000 and its expected life is five years.
Required:
Calculate depreciation expense and complete the following schedules for 2017 and 2018 for each of the following methods.

A. Straight Line Depreciation
B. Sum of the Years Digits

Answer 1

Answer and Explanation:

The computation of the depreciation expense for 2017 and 2018 under the following methods

a. Straight-line method

= (Purchase cost - residual value) ÷ (estimated life)

= ($400,000 - $100,000) ÷ (5 years)

= $60,000

Since the depreciation expense under this method would remain the same for the remaining useful life

So for 2017 and 2018, the depreciation expense i.e. $60,000 would be charged every year.

b. Under the sum-of-the-year-digits method

For 2017,

= ($400,000 - $100,000) × 5 years ÷ ( 5 + 4 + 3 + 2 + 1)

= $300,000 × 5 years ÷ 15 years

= $100,000

For 2018, the book value is

= $400,000 - $100,000

The $100,000 is the depreciation expense of 2017 year

= $300,000 × 4 ÷ 15

= $80,000
