The formula generally used to estimate WACC is: The tax benefits resulting from debt finance play an important role in evaluating the debt versus equity funding of an entity.

Given that interest, if incurred in the production of taxable income, is deductible for income tax purposes, the cost of debt is effectively the after tax cost and not the before tax cost. The effective cost of the debt is will be 7.

The after tax cost of the debt is therefore generally less than the cost of equity. While there are various arguments supporting the use of debt as opposed to equity to fund a company, the primary argument lies in the tax saving presented by debt.

Ce — cost of equity Unlike debt holders, equity shareholders do not demand an explicit return on their capital invested. Given that equity shareholders have the opportunity of investing their capital in an alternative company with a similar risk profile, equity shareholder have an implicit opportunity cost investing in an entity.

The cost of equity is therefore the rate of return that shareholders require in order to be compensated for the risk associated with the investment in the entity. A number of different methods may be used to determine the cost of equity required rate of returnall of which however require some form of estimation.

Two of the most commonly used cost estimation methods are the capital asset pricing model CAPM and the dividend yield or growth model. The detailed workings of these two methods are considered beyond the scope of this article.

Almost every finance textbook explicitly states that the weightings in the cost of capital calculation are be based on market values and not book values.

It should however be remembered that basing the rate or return on the historical book value will not reflect the current economic reality. The justification for using market values therefore lies in the required rate of return that investors currently require relative to their current risk exposure.

Explanation of Formula Elements

The problem however is that the target capital structure often bears little resemblance to the actual capital structure, thus distorting the WACC. It is however acknowledged that it is more practical to use the target WACC approach than estimating annual market weightings that vary depending on the life stage of the business.

EV — enterprise value of company The enterprise value is simply market value of the equity plus the market value of the debt. Considering that market value of debt and equity are used to determine the respective weightings of debt and equity, the enterprise value is also based on market values.

The WACC based on the current debt to equity ratio is as follows: Determine the current market values Shares market value given R2. This was calculated as follows: Cost of long-term debt finance is the after tax market rate of 7.Join Jim Stice and Earl Kay Stice for an in-depth discussion in this video, Weighted-average cost of capital, part of Finance Foundations.
