Under the double declining balance method, depreciation is twice or 200% of the straight line depreciation rate. Its computation is as follows:
Straight-Line Depreciation Percent = 100% /10 years = 10% / year.
Depreciation Rate = 2 x 10%
= 20% /year.
Depreciation for a Period = 20% x Book Value at Beginning of the Period of January 1
Depreciation for Period 1 (first year) = 20% x $5,400 = $1080
Depreciation for Period 2 (second year) = 20% x ($5,400- $1080)
= 20%($4320)
= $864
