Weighted average cost of capital (WACC) is the minimum return which a company is supposed to give on an average to satisfy its entire security proprietors to finance its assets. This tutorial explains you how to calculate Weighted average cost of capital.

Calculator of Weighted Average Cost of Capital

Cost of Equity (Re) = %
Cost of Debt (Rd) = %
Market value of the firm's equity (E) =
Market value of the firm's debt (D) =
Corporate tax rate (Tc) = %
 
 
 
Weighted Average Cost of Capital = %

Formula of Weighted Average Cost of Capital

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

Where,

  • WACC = Weighted Average Cost of Capital
  • E = Market value of the firm’s equity
  • D = Market value of the firm’s debt
  • V = Firm Value
  • Re = Cost of Equity
  • Rd = Cost of Debt
  • Tc = Corporate tax rate

Example of Weighted Average Cost of Capital

Company Hiox has a beta of 1.65. The current equity market risk premium is 7%, and the risk-free rate is 3%. Its before-tax cost of debt is 6% and its marginal tax rate is 40%. The stock sells at Long-Term Debt 6000 and Equity 1500. Find the WACC percentage of the company.?

Given

Market value of the firm’s equity (E) = 1500 Market value of the firm’s debt (D) = 6000 Cost of Equity (Re) = 3% + (7% x 1.65) = 14.55% Cost of Debt (Rd) = 6% Corporate tax rate (Tc) = 40%

To Find

Weighted Average Cost of Capital

Solution

Step 1

Find value of V

V = E + D V
= 1500 + 6000
= 7500

Step 2

WACC = (E/V x Re) + [(D/V x Rd) x (1-Tc)]
= (1500/7500 x 0.1455) + [(6000/7500 x 0.06) x (1-0.4)]
= 5.79 %
