Not all calendar years consist of 365 days because some are leap years that consist of 366 days. Therefore, a daily depreciation expense must be calculated upon which periodic depreciation expense and book values are calculated.
The annual depreciation rate is calculated based on the depreciation method you select, and then calculates the daily depreciation rate based on the following equation:
Daily Depreciation Rate = Annual Depreciation Rate / Number of Days in the Year
Specify the depreciation method that the system should use to calculate the annual depreciation expense on the Depreciation page of the Assets, Positions, or Systems form.
See Entering depreciation data.
Four asset depreciation methods are provided: Straight Line, Sum of Years Digits, Double Declining Balance, and Units of Output.
The ASDEPTYP installation parameter determines the default depreciation method for
the system; however, you can also set the depreciation method on the organization
or equipment level. Setting the depreciation method at the organization level supersedes
the setting of the ASDEPTYP installation parameter. Setting the depreciation method
at the equipment level supersedes the setting of ASDEPTYP and/or the depreciation
method specified for the organization.
