Answer:
$91,429
Step-by-step explanation:
Depreciation using the double-declining balance method is calculated as follows :
Depreciation expense = 2 x SLDP X BVSLDP
where,
SLDP = 100 ÷ useful life
= 100 ÷ 10
= 10%
therefore,
2018
Depreciation expense = 2 x 10% x $1,250,000 = $250,000
2019
Depreciation expense = 2 x 10% x ($1,250,000 - $250,000) = $200,000
2020
Depreciation expense = 2 x 10% x ($1,250,000 - $250,000 - $200,000 = $160,000
2021
Step 1 : New Depreciable Amount calculation
New Depreciable Amount = Cost - Accumulated depreciation to date
where,
Accumulated depreciation = total depreciation to date
= $250,000 + $200,000 + $160,000
= $610, 000
therefore
New Depreciable Amount = $1,250,000 - $610, 000
= $640,000
Step 2 : New useful life calculation
New useful life = 10 - 3 = 7
Step 3 : Depreciation expense
Depreciation expense = New Depreciable Amount ÷ Estimated useful life
= $640,000 ÷ 7
= $91,429
The depreciation expense for 2021 would be $91,429
