Each of the years 2012, 2013, and 2014 will incur a $6,000 depreciation expense.
figured out as follows:
Amount to Be Depreciated = Cost of $30,000 less Estimated Salvage Value of $0.
For the years 2012, 2013, 2014, and 2015, $30,000 divided by ten years equals $3,000 every year.
The Book Value is $18,000 after 4 years ($30,000 minus $12,000).
Depreciation of the $18,000 book value will be required over the remaining 3 years= $6,000 annually.
