WACC Calculator | Calculate Weighted Average Cost of Capital (WACC)

Understanding WACC

WACC stands for Weighted Average Cost of Capital. It represents the average rate of return a company is expected to pay its security holders to finance its assets. In simpler terms, it’s the average cost of capital that a company must pay to fund its operations and growth. Calculating WACC helps businesses understand how much they need to earn on their investments to satisfy their investors.

Why is WACC Important?

WACC is crucial for several reasons:

• Investment Decisions: Companies use WACC as a hurdle rate when assessing new projects. If a project’s return exceeds WACC, it could create value for the company.
• Valuation: WACC is often used in discounted cash flow (DCF) analysis to determine the present value of future cash flows.
• Capital Structure Assessment: Understanding WACC helps companies balance debt and equity financing to minimize their overall cost of capital.

How to Calculate WACC

Calculating WACC involves determining the cost of equity and the cost of debt and weighting them based on the company’s capital structure. Here’s a simple formula for WACC:

WACC Formula

WACC=(EV×re)+(DV×rd×(1-T))text{WACC} = left( frac{E}{V} times r_e right) + left( frac{D}{V} times r_d times (1 – T) right)

WACC=(VE×re)+(VD×rd×(1–T))

Where:

• 
  EE 

  $E$ = Market value of equity

• 
  DD 

  $D$ = Market value of debt

• 
  VV 

  $V$ = Total market value of the company’s financing (Equity + Debt)

• 
  rer_e 

  re = Cost of equity

• 
  rdr_d 

  rd = Cost of debt

• 
  TT 

  $T$ = Tax rate

Components of WACC Calculation

1. Market Value of Equity (E): This is the total value of the company’s equity, calculated as the current share price multiplied by the total number of outstanding shares.
2. Market Value of Debt (D): This includes all interest-bearing liabilities, such as bonds and loans, valued at their current market price.
3. Cost of Equity (r_e): This represents the return that equity investors expect from their investment. It can be estimated using the Capital Asset Pricing Model (CAPM), given by:

    

   re=rf+?×(rm-rf)r_e = r_f + beta times (r_m – r_f)re=rf+?×(rm–rf)

   Where:

   • 
     rfr_f 

     rf = Risk-free rate

   • 
     ?beta 

     $?$ = Measure of a stock’s volatility compared to the market

   • 
     rmr_m 

     rm = Expected return of the market

4. Cost of Debt (r_d): This is the effective rate that a company pays on its borrowed funds. It can be calculated using the yield to maturity on existing debt or the interest rate on new debt.
5. Tax Rate (T): The corporate tax rate that affects the cost of debt.

How Do You Calculate WACC?

To calculate WACC, follow these steps:

1. Determine the Market Values: Calculate the market values of equity and debt using the formulas provided above.
2. Calculate Cost of Equity and Cost of Debt: Use CAPM for cost of equity and determine the effective interest rate for cost of debt.
3. Plug the Values into the WACC Formula: Use the WACC formula to compute the final value.

Example of WACC Calculation

Let’s say a company has:

• Market Value of Equity (E): $500,000
• Market Value of Debt (D): $200,000
• Cost of Equity (r_e): 8%
• Cost of Debt (r_d): 5%
• Tax Rate (T): 30%

First, calculate the total market value (V):

V=E+D=500,000+200,000=700,000V = E + D = 500,000 + 200,000 = 700,000

V=E+D=500,000+200,000=700,000

Next, plug these values into the WACC formula:

WACC=(500,000700,000×0.08)+(200,000700,000×0.05×(1-0.30))text{WACC} = left( frac{500,000}{700,000} times 0.08 right) + left( frac{200,000}{700,000} times 0.05 times (1 – 0.30) right)

WACC=(700,000500,000×0.08)+(700,000200,000×0.05×(1–0.30))

After calculating the values, you’ll get the WACC for the company.
