What do you call the after-tax present worth of all depreciation effects over the depreciation period of the asset?

The concept referred to in the question is indeed called depreciation recovery, which is the after-tax present worth of all depreciation effects over the depreciation period of the asset. When an asset is depreciated, it reduces taxable income, thereby affecting the cash flow associated with the asset. The tax savings generated from depreciation represent a cash inflow that can be considered a recovery of the asset’s cost over time.

Depreciation recovery captures the financial benefits that accrue due to the tax shield provided by depreciation deductions. This means that during the asset's useful life, the accounting for depreciation impacts the cash flows in such a way that it offsets the original investment, providing a more accurate representation of the net worth of the asset after accounting for taxes.

This understanding is crucial in the field of engineering economics and management, as it directly influences investment decisions and financial planning. The terms asset recovery, period recovery, and after-tax recovery do not specifically focus on the comprehensive analysis of tax effects associated with depreciation as clearly as depreciation recovery does. Each of these alternatives lacks the explicit connection to the systematic taxation benefits derived from asset depreciation.
