Section 13
Investment Analysis
Partial-Year Depreciation
For both income tax purposes and financial analyses, it is valuable to calculate
depreciation based on a calendar or fiscal accounting year. When the acquisition
date of an asset does not coincide with the start of the year – which is the rule
rather than the exception – the amounts of depreciation in the first and last years
are computed as fractions of a full year’s depreciation.
Straight-Line Depreciation
The following HP 12C Platinum program (written in RPN mode) calculates the
straight-line depreciation for the year desired with the acquisition date occurring
at any time during the year.
