RE: Repair Cost: Rear Main Seal? I have a 1997 Lexus ES 300, and it appears to be leaking oil at the rear main seal connection. How much would it cost to replace, and what other parts/belts should be replaced during that same repair (e.g. water pump, timing belt, etc)? have a 1997 Lexus ES 300, and it appears to be leaking oil at the rear main seal connection.
From Wikipedia, the free encyclopedia. In economics and accounting, the cost of capital is the cost of a company's funds (both debt and equity), or, from an investor's point of view the required rate of return on a portfolio company's existing securities.It is used to evaluate new projects of a company.ince in most cases debt expense is a deductible expense, the cost of debt is computed as an after tax cost to make it comparable with the cost of equity (earnings are tax as well). Thus, for profitable firms, debt is discounted by the tax rate.
Equity = Shares Market Price * Shares Issued. Cost of Debt is usually defined as the after-tax cost of debt: After-tax Cost of Debt = (1- Tax Rate)* Cost of Debt. The WACC Calculator spreadsheet uses the formula above to calculate the Weighted Average Cost. of Capital.
