CHAPTER

Depreciation Accounting Techniques
1. A contractor purchased a tractor for $180,000 and anticipates using it for nine years. The
salvage value of the tractor at the end of the nine years is estimated to be $27,000. Using the
straight-line method of depreciation accounting, determine the book value of the tractor at the
end of each of the nine years.
The annual depreciation rate can be determined with Equation 3.1 to be
The annual depreciation amount can be determined with Equation 3.2 to be
The book value for each year can be determined with Equation 3.3 as shown in the table
below.

5. A contractor purchased a crane for $460,000 and plans to use the crane for eight years, at
which time she plans to sell the crane for 10% of its acquisition cost. The contractor is
considering using either the sum-of-the-years method of depreciation accounting or the
double declining-balance method of depreciation accounting.
a. If the contractor uses the sum-of-the-years method of depreciation accounting, what
will be the book value of the crane after two years of use?
