For year 2017 and 2018:
Cost of machiney = $45,000
Salvage Value = $3000
Estimated life = 8 years
Depreciation per year = (Cost of Machinery - Salvage Value) / Estimated Life
= (45000 - 3000) / 8
= 42000 / 8
= $5,250
Depriciation charged during 2017 and 2018 = $5,250 X 2 = $10,500
During 2019:
Cost of machinery = $45,000
Salvage Value = $2,000
Estimated Life = 6 years
Revised Depreciation per year = (Cost of Machinery - Salvage Value) / Estimated Life
= (45000 - 2000) / 6
= 43000 / 6
= $7,166.67 per year
Since, the company will not make adjustments to the prior years, hence the revised depreciation cost would be booked during 2019.
Cost that should have been booked during 2017 and 2018 = Revised Depreciation per year X 2 = $7,166.67 X 2 = $14,333.33
Cost that have been booked = $10,500
Cost that is required to be booked for 2017 and 2018 = Cost that should have been booked during 2017 and 2018 - Cost that have been booked
= $14,333.33 - $10,500
= $3,833.33
Further, the cost of depreciation for 2019 = $7,166.67
Total cost of depreciation to be booked in 2019 = Cost that is required to be booked for 2017 and 2018 + cost of depreciation for 2019
= $3,833.33 + $7,166.67
= $11,000
Entry for depreciation cost for 2019:
Depreciation A/c Dr. $11,000
To Accumulated Depreciation $11,000
(Being depreciation charged and transferred to Accumulated Depreciation A/c)
