What Is WACC (Weighted Average Cost of Capital)?

To run a business well, a company needs funds from multiple sources. Some of these are banks, equityholders, debt, and even the fund against the promoter holdings. But at the same time, it is important to evaluate the equity and debt components in your capital as well.

This is where you would need to use WACC. A simple concept, this is used to understand the overall cost of financing for your business. But that is not it. There is more to it than you should understand.

So, if you are looking to know what WACC is, then read this guide. Explore the meaning, formula, and how you must use the same well here in this guide. 

What is WACC?

WACC stands for Weighted Average Cost of Capital. It shows the average cost a company pays to raise money for its business. This money usually comes from two main sources. One is equity, which is shareholders’ funds. The other is debt, such as loans or bonds.

In simple terms, WACC tells you how much return a company must earn to satisfy both its lenders and its investors. If a company earns more than its WACC, it is creating value. If it earns less, value is being lost.

WACC is widely used in financial management. Companies use it to check whether a new project is worth investing in. Investors use it to understand the business. It also gives an estimate of where the business stands on the riskometer. This means a lower WACC is better than a higher one. 

Overall, WACC acts as a benchmark. It helps in decision-making, valuation, and long-term planning.

WACC Formula Explained Simply

The WACC formula shows how the cost of equity and debt are combined, based on how much each source contributes to the total capital of a company. It also adjusts debt cost for tax savings.

WACC Formula

Here is what each of these means:

• E is the market value of equity

• D is the market value of debt

• V is the total capital, which is E + D

• Re is the cost of equity

• Rd is the cost of debt

• Tax Rate is the corporate tax rate

Equity cost is taken at full value because dividends are not tax-deductible. Debt cost is reduced by tax since interest paid on loans saves tax for the company.

This formula helps companies find their average cost of funding. It is widely used in project evaluation, company valuation, and financial planning.

How to Calculate WACC

Calculating WACC becomes easy when you break it into clear steps. The aim is to know how well the company is using its funds. This is for business and operations. So, the steps are as follows.

Step 1: Identify Total Capital

First, calculate the total capital used by the company. This should include the market value of equity and debt. A complete analysis will show the actual value of the money invested.

Step 2: Calculate the Cost of Equity

The cost of equity is the return expected by shareholders. It reflects the risk of investing in the company. Higher risk usually means a higher cost of equity.

Step 3: Calculate the Cost of Debt After Tax

The cost of debt is the interest rate paid on loans or borrowings. Since interest saves tax, reduce this cost using the corporate tax rate to get the after-tax cost.

Step 4: Find the Weights of Equity and Debt

Now, calculate how much equity and debt contribute to total capital. These weights decide how strongly each cost impacts WACC.

Step 5: Apply the WACC Formula

Multiply the cost of equity and cost of debt by their respective weights. Now, the values that you get should be added further. This will give you the final WACC. 

Step 6: Understand the Result

Now, once you have the WACC value, it is time to evaluate it. So, here is how you can evaluate the same:

• When the WACC is high, the risk and cost of capital are high. This will lower the valuation of the company.

• If the WACC is low, then the cost of capital and the risk are low. This shows that the valuation of the company is high.

Why Investors Should Use WACC in Financial Management

WACC plays a key role in helping investors judge whether a company is worth investing in. It gives a clear view of how efficiently a business uses its capital and how much risk is involved.

1. Understand Whether a Company Is Truly Creating Value

A company may report profits, but that alone is not enough. WACC shows the minimum return that the company needs to show its working efficiency. This shows how well the capital is used by the business. When returns stay above WACC, it signals real value creation for investors.

2. Make More Practical Valuation Judgments

WACC helps investors estimate what a business is actually worth. It is used to adjust future earnings for risk. By using this, you are able to get the realistic valuations. This allows you to pay the right amount and avoid overpaying for uncertain growth periods.

3. Compare Companies on a Common Ground

Different companies use different mixes of debt and equity. WACC brings them to the same level for comparison. Investors can clearly see which businesses manage capital better and carry lower risk.

Other Key Metrics to Use Along With WACC

WACC is quite helpful. But you need to use other metrics as well. Some of the other things to consider are:

1. Return Ratios and Cash Flow Metrics

Metrics like ROE, ROCE, and free cash flow help investors check whether returns are strong enough to beat WACC. Cash flow helps to understand the actual place where money is used.

2. Valuation and Market-Based Indicators

Market capitalization, price to earnings ratio, and enterprise value help understand the market value of the business. Comparing this with WACC helps you arrive at the actual valuation.

3. Financial Strength and Risk Measures

Debt-to-equity ratio, interest coverage ratio, and credit profile show how risky the capital structure is. These metrics ensure that you understand company performance.

Conclusion

WACC is more than just a financial formula. It is a metric that helps analyse the actual value of the company. By comparing company returns with WACC, investors can avoid weak businesses and focus on those that use capital wisely. With the help of WACC, you can get clarity in investment.
