## Overview of **WACC**

**Definition**

**The weighted average cost of capital (WACC) indicates a firmâ€™s average cost of capital from all components, and different types of stocks like preferred stock, common stock, bonds, and other types of debt.**

- The
**WACC**is also regarded as the rate at which the organization had to pay its stakeholders. Another name is**Simple Cost of Capital**. - Most businesses had to fund their operations, and this capital is usually through debt, equity, or an amalgamation of the two. There is a cost tag attached to every information source.
- Calculating the
**WACC**is a useful tool for comparing various financing choices because it gives the company an idea of how much the venture or business will**cost to fund**. If the value is less than the financial return, the project will add value or assets to the company. Otherwise, if the calculated**WACC**is more than the return on investment, then the project will lose money or asset in the long run. - The
**WACC**also helps to understand which proportion of equity and Debt will bring the best**WACC**rate.Â They need to tweak the proportions of the debt and equity with respect to the total capital until they find the best possible**WACC**.

**Formula of WACC**

Here,

**E **= **Equity Value** of the Company

**V **= **Total Value of Debt** and **Equity** of a Company.

**D **= **Total Debt** of a Company.

**Tc **= **Tax Rate**.

**Re** = **Cost of Equity**.

**Rd** = **Cost of Debt**.

We can also present it like the below image.

Here weightage is basically the ratio of **Equity** and **Debt** with respect to the summation of **Equity** and **Debt.**

## Components of **WACC**

**WACC** has four essential parameters or components. Without any of them will make calculations of the **WACC** impossible.

**1. Market Valuation of Equity**

The market value of the Equity is mostly regarded as the summation of the price of outstanding shares of a particular company.

**2. Cost of Debt**

This is the price that the company must pay for the debt (bonds or loans) it took.

**The Cost of Debt**is a very good indicator of a companyâ€™s risk factor. Riskier companies have a higher amount of**Cost of Debt**compared to the other companies.- They are calculated by the following formula:

**Cost of Debt****Â = Interest rate x (1 â€“ Tax rate)**

**3. Market Valuation of Debt**

Estimation of the total Debt is troublesome as the debt in most cases isnâ€™t public. They usually donâ€™t even list in the outstanding share also. It can be calculated from the listed bond price or from the bank statements.

**4. Cost of Equity**

In one word, it defines as the rate of return of stocks or shares issued by the company as expected by the shareholder.

- When a share is issued, the company doesnâ€™t pay any money for the stock. Instead, it sells a small chunk of the company share, and the share is bought by the shareholders.
- As the performance of the company gets ups and downs, so do the stock prices also. But shareholders expect a certain amount of return front the share they bought. The return has to generate by the company.
- This is the price the company must pay in the long run in order to generate investment. This cost is described as the
**Cost of Equity**. It is presented as the formula below:

**Cost of Equity = Risk Free Rate + Beta * (Market Return Rate â€“ Risk Free Rate)**

## Step-by-Step Procedure to Calculate **WACC** in Excel

Below, an example of how you can calculate the **WACC** of a company is presented with a step-by-step procedure.

### Step 1: Prepare Dataset

Before we delve into calculating **WACC**, we need to prepare the input data which will help us to calculate the **WACC.**

- In order to calculate the
**WACC**, we need to calculate some parameters or the component first. - The components are
**Cost of Equity**,**Equity Evaluation**,**Cost of Debt**,**Debt Valuation,**etc. - Furthermore, we need some more information to calculate those parameters.
- Those pieces of information are organized as shown below.
- Each parameter required unique information.
- Like
**Cost of Equity**required information like**Rate of Risk-Free**,**Beta**, and Market return. - And
**Cost of Debt**required information like**Rate**,**Tax Rate**, and**Credit Spread**. - And
**Equity**and**Debt**requirements vary wildly from company to company. **Equity**actually represents the total amount of money that the company had to return if they decide to liquidate all the assets. So the calculation may involve shares of different types, retained earnings, etc. In this case, we presented only the share quantity and the price per share. With this, we could calculate the total price of the share hence the total**Equity**.

### Step 2: Estimate **Cost of Equity**

Now as we have the necessary information, we can now determine the **Cost of Equity**.

- Now we are going to calculate the
**Cost of Equity**using the parameters presented here. - To do this, select the cell
**C8**and enter the following formula:

`=C5+C6*(C7-C5)`

- Entering this formula will instantly calculate the
**Cost of Equity**in cellÂ**C8**.

### Step 3: Calculate Market Valuation of Equity

Now as we have the necessary information, we can now determine the Market Valuation of Equity.

- Now we are going to
**Evaluate****the Equity**using the parameters presented here. - To do this, select the cell
**F7**and enter the following formula:

`=F5*F6`

- Entering this formula will instantly calculate the
**Total Equity**in the form of**Total Share Value**in cell**F7**.

### Step 4: Estimate **Cost of Debt**

Now as we have the necessary information, we can now determine the **Cost of Debt.**

- Now we are going to Evaluate the
**Cost of Debt**using the parameters presented here. - To do this, select the cell
**C14**and enter the following formula:

`=(C11+C13)*(1-C12)`

- Entering this formula will instantly calculate the
**Cost of Debt**in cell**C14**.

### Step 5: Calculate Market Valuation of Debt

Now as we have the necessary information, we can now determine the **Market Valuation of Debt**.

- Now we are going to Evaluate the
**Cost of Debt**using the parameters presented here. - To do this, select the cell
**C14**and enter the following formula:

`=F11*F12`

- Entering this formula will instantly calculate the
**Cost of Debt**in cell**C14**.

### Step 6: Estimate Gross Capital

From the value of debt and equity, we can find the **Gross Capital** by summing them up.

- Now we are going to evaluate the
**Total Capital**using the parameters presented here. - To do this, select the cell
**F15**and enter the following formula:

`=F7+F13`

- Entering this formula will instantly calculate the
**Total Capital**in cell**F15**.

### Step 7: Calculate **WACC** (Weighted Average Cost of Capital)

Now we have all the necessary parameters in order to calculate the **WACCÂ **in Excel.

- In order to calculate this, select cell
**F17**and enter the following:

`=C8*(F7/F15)+C14*(F13/F15)*(1-C12)`

- This formula will directly calculate the
**WACC**in cell**F17**.

### Step 8: Interpret Outcome

The final value of the **WACC** we got is about around 31.42%. Which is quite high. We already know that the higher **WACC** compared to the expected return results in higher instability. This actually means that the business is paying much more for the capital than its earnings. Which results in a loss of assets.

- In the example shown above, the
**WACC**is**31.42%.**We didnâ€™t put any expected return on the business. Say, if the expected return is 15%, then we could say that the business is losing money at (31.42%-15%) or at a 16.42% rate. This venture is, therefore, more volatile for investment. - On the other hand, if the expected return is 35%, then we can say that the business is generating wealth at the (35%-31.42%) or 3.58% rate. This investment is preferable and safe for the investment.

## đź’¬ Things to Remember

Although **WACC** brings a lot to the table in terms of helping investors taking a decision regarding investment, and for the owner for determining how the company is performing in the market, it still has some limitations.

- The calculations seem pretty straightforward when all the parameters are in the sheet. But the reality is that determining parameters like equity, and debt is pretty difficult because they are being reported for various reasons on various occasion
**WACC**also assumes that the investing in the company, or the capital, will flow in the same way throughout the year. But this isnâ€™t possible actually in most cases.
