Understanding the WACC Formula

The WACC Formula, also known as the Weighted Average Cost of Capital, is a mathematical equation used in financial and accounting calculations. It is an important tool used by companies to assess and evaluate the cost of borrowing, issuing and repaying capital, as well as the rate of return they can expect in the long run. In simple terms, the WACC Formula provides a calculation that estimates the rate of return on a company’s investments by taking into account the cost of each type of capital that is used by the company.

Components of the WACC Formula

The WACC Formula is composed of three main components: the cost of debt, the cost of equity and the company’s capital structure. The cost of debt takes account of the interest rate on the company’s existing debt and other borrowed capital that it has accessed or plans to access. The cost of equity reflects the rate at which the company can raise capital, including from investors in its equity or from banks. Finally, the company’s capital structure takes into account the weights of its debts and equity in terms of the company’s total capital.

Impacts of Applying the WACC Formula

When using the WACC Formula, companies must consider how each of the components may be impacted by market forces. For example, when the overall market rate of interest rises, the cost of debt will also increase, thus resulting in a higher WACC. Similarly, if a company’s share price falls, the cost of equity will also go down resulting in a lower WACC. Consequently, a company must keep a close eye on the market and the current rates of interest to accurately calculate their WACC and plan for the future accordingly.

Applying the WACC Formula also allows companies to accurately assess the risk associated with their investments. This is because higher levels of debt burden the company with a greater risk as they must pay higher rates of interest in order to secure loans. This risk is also reflected in their cost of equity, as investors will demand higher returns for higher risk. Thus, by calculating the WACC, companies can accurately determine the cost of their resulting investment.

Finally, the WACC Formula is a useful tool for companies in determining the rate of return they can expect in the future. By using the calculated WACC, companies can compare the projected expected return of an investment to the actual return they are expecting to receive. If the actual return is lower than what is projected, it may be in the company’s best interest to avoid investing in that particular venture.

Introduction To WACC Formula

An organized and structured way of calculating the cost of capital of a company is via the WACC formula. This formula has been proposed by Farber, Gillet and Szafarz in 2006 and helps to calculate the expected return of the company’s tax shield. WACC stands for Weighted Average Cost of Capital, and it is a formula used to determine the combined cost of the different borrowing and equity sources that a corporation uses to raise money. It allows for the calculations of an expected market rate of return for the investments of a certain company.

Structure Of WACC Formula

The WACC formula takes into account the different sources of capital or financing the company receives. This can include debt, preferred stock, common equity and other. The formula weights the cost of each type of capital by applying price to the proportion that each of them represents. Each type of capital has its own cost associated with it, because different sources of capital require different amounts of returns.

The main components that make up the WACC formula are the weighted average cost of equity, the cost of debt, tax rate and the proportion of debt to equity. The cost of equity is the expected return investors require on average in order for them to be willing to invest in a company’s equity. The cost of debt is the cost of money the company has to pay for borrowing money. The tax rate should reflect the expected rate at which the company will pay taxes. Finally, the debt/equity ratio also enter the equation for accurate calculations of WACC. Knowing the equity cost and the debt cost, WACC can be calculated simply by applying the formula: WACC = (E/V) × Re + (D/V) × Rd × (1-T), where E/V is the proportion of equity in the capital structure, Re is the cost of equity, D/V is the proportion of debt in the capital structure and Rd is the cost of debt.


The WACC formula is a powerful tool for company and investors when trying to determine the expected market rate of return. It is an important equation that allows for the correct valuation of investments in order to make sound long-term decisions that weigh up risks and rewards. The main components of the WACC formula are weighted average costs of equity, the cost of debt, total debt to equity ratio and the company’s tax rate. Taken these components into account, a company’s cost of capital can be accurately calculated.
