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.
Weighted Average Cost of Capital (WACC) is the average cost to a company of the funds it has invested in the assets of the company. This is composed of a possible combination of debt, preferred shares, common shares and retained earnings. All components of the cost of capital are determined at the current market rates.eighted Average Cost of Capital (WACC) is the average cost to a company of the funds it has invested in the assets of the company.
