The specification of year, month, and percent in the Depreciation pattern screen group on the Basic Info tab of the Data -> Equipment Units -> Setup -> Value Depreciation screen depends on which method you use to depreciate the value of equipment units assigned to the value depreciation ID.

Under the straight-line method, the value depreciates by the same percentage each month. Under the accelerated method, the value decreases by a smaller percentage each month.

Straight-line depreciation

The following sample entries specify a straight line depreciation method, in which the value of the equipment unit depreciates 1.042% each month during the first year of service.

Accelerated depreciation

The following sample entries specify an accelerated depreciation method, in which the value of the equipment unit depreciates by a smaller percentage each month during the first year of service. Eventually, by the eighth year of service, the depreciation percentage is considerably smaller than during the first year.
