Tax-deductible expenses such as maintenance, energy, operating costs, insurance, and property taxes reduce the income subject to taxes.
For the after tax life cycle cost analysis and payback analysis the actual incurred and annual savings is given as follows.
AS is the yearly annual after tax savings (excluding effect of tax credit)
E is the yearly annual energy savings (difference between original expenses and expenses after modification) D is the annual depreciation rate I is the income tax bracket.
Equation 9-23 takes into account that the yearly annual energy savings is partially offset by additional taxes which must be paid due to reduced operating expenses. On the other hand, the depreciation allowance reduces taxes directly.
