Meaning of WACC and factors affecting the WACC

The weighted average cost of capital (WACC) is the average rate that a business pays to finance its assets. The purpose of WACC is to determine the cost of each part of the company’s capital structure based on the proportion of equity, debt, and preferred stock it has. Each component has a cost to the company. The company typically pays a fixed rate of interest on its debt and a fixed dividend on its preferred stock. While a firm does not pay a fixed rate of return on common equity, it often distributes cash dividends.

WACC calculates a company’s cost of capital by proportionately weighing its use of debt and equity financing. Unlike measuring the costs of capital separately, WACC takes the weighted average for each source of capital for which a company is liable. The formula for calculating WACC is:

WACC = [(E/V) x Re] + [(D/V) x Rd x (1 – Tc)]

Where:

• E = Market value of equity
• D = Market value of debt
• V = Total capital (equity + debt)
• E/V = Percentage of capital that is equity
• D/V = Percentage of capital that is debt
• Re = Cost of equity (required rate of return)
• Rd = Cost of debt (yield to maturity on existing debt)
• Tc = Corporate tax rate

The WACC formula helps determine the rate between market values and costs of equities and debts. The market value of equity is equivalent to market capitalization, which is calculated by multiplying the total shares outstanding by the current share price. The market value of equity fluctuates throughout the trading day as the stock price changes.

WACC is the rate a company is expected to pay on average to all its security holders to finance its assets. It is commonly referred to as the firm’s cost of capital. A higher WACC generally indicates a riskier investment, while a lower WACC correlates with more stable business investments. A favorable WACC reassures investors about the security and profitability of their investment.

WACC is calculated by multiplying the cost of each capital source by its relevant weight in terms of market value and then summing the results to determine the total. Companies and investors often use WACC as a hurdle rate to evaluate the desirability of potential projects or acquisitions.

For example, a WACC of 12% indicates that, on average, a company must provide its investors with a 12% return on their capital. This serves as a benchmark for new investments, meaning any project should yield a return higher than 12% to create value for the company. As a general guideline, mature companies tend to have WACC values ranging from 2-3% within their industry. Determining an appropriate WACC depends on various industry factors.

Factors Affecting WACC:

1. Cost of Equity: Factors influencing the cost of equity include dividend per share, market value of the share, and dividend growth rate.
2. Cost of Debt: The cost of debt is affected by interest rates on existing debt. A more accurate measure is the average yield to maturity (YTM) on the company’s long-term debt.
3. Corporate Tax Rate: A higher corporate tax rate reduces the after-tax cost of debt, thereby lowering WACC.
4. Capital Structure: The combination of a company’s equity and debt impacts its overall WACC.
5. Market Conditions: Stock market volatility, economic conditions, and prevailing interest rates can influence WACC.
6. Risk: Economic conditions can impact WACC by altering default risks and influencing central bank interest rate policies.
7. Company’s Financial Health: Strong financial health can reduce WACC by lowering perceived risk.

Conclusion:

The Weighted Average Cost of Capital (WACC) is a crucial financial metric that helps companies determine the minimum return they must generate on their investments. It aids in assessing the profitability of different investments and projects, ensuring informed decision-making.
