Schedule of Straight-line, Units of Production, and Double Declining Balance:
Straight-line Units of Production Double Declining
Year 1 Book value $350,000 $350,000 $350,000
Depreciation Exp. $80,000 $96,000 (30,000*$3.20) $175,000
Year 2 Book value $270,000 $254,000 $175,000
Depreciation Exp. $80,000 128,000 (40,000*$3.20) 87,500
Year 3 Book value $190,000 $126,000 $87,500
Depreciation Exp. $80,000 64,000 (20,000*$3.20) 43,750
Year 4 Book value $110,000 $62,000 $43,750
Depreciation Exp. 80,000 32,000 (10,000*$3.20) $13,750
Residual value $30,000 $30,000 $30,000
Explanation:
a) Data and Calculations:
Cost of new machine = $350,000
Estimated useful life = 4 years or 100,000 hours
Residual value = $30,000
Usage of machine:
Year 1 = 30,000 hours
Year 2 = 40,000 hours
Year 3 = 20,000 hours
Year 4 = 10,000 hours
Units of Production = $320,000/100,000 = $3.20 per unit
Depreciable amount = $320,000 ($350,000 - $30,000)
Straight-line method, Depreciation per year = $80,000 ($320,000)
= 25% (100/4).
Depreciation expense, using Double-Declining Balance rate = 25% * 2 = 50%:
Year 1 = $350,000 * 50% = $175,000
Year 2 = $175,000 * 50% = $87,500
Year 3 = $87,500 * 50% = $43,750
Year 4 = $13,750 ($43,750 - $30,000)
b) These different methods still arrive at the same end result as shown above. Note that depreciation is an accounting estimate which spreads the cost of an acquired long-term asset over its useful life.
