Real Estate Property Depreciation
The core calculation is for straight line depreciation, as the name suggests, it is a straight line drop in asset value. The depreciation of an asset is spread evenly across the life.
This calculator is specific for property that is real estate. The key difference from normal straight line depreciation is that a mid month convention is used in calculating depreciation in the first and last years. That is, only 1/2 month of depreciation is calculated for the months the property was put into or taken out of service.
With real estate the total cost basis is depreciated so there is no salvage value.
- Depreciation in Any Full year = Cost / Life
- Partial year depreciation, when the property was put into service in the M-th month is taken as:
- First year depreciation = (((12-M)+0.5) / 12) * (Cost / Life)
