Straight-Line, Half-Year Example

For a $14,000 truck placed in service on March 16, 2007, with an estimated life of 6 years and a salvage value of $2,000, the depreciation calculation for the straight-line method looks like this:

 

Original cost

$14,000

-

Salvage value

   2,000

 

Adjusted basis

$12,000

 

Adjusted basis
Estimated life

=

$12,000
6

= $2,000

Yearly depreciation is $2,000 for the years 2008 through 2012. Since the truck was placed in service in March, the 2007 depreciation using the half-year convention is one-half of the annual depreciation, or $1,000. The depreciation for the last year is also one-half of the annual depreciation, or $1,000.
