Data Source and Methodology

All calculations are based on the formulas and data provided by authoritative financial sources. a third-party source, 2023.

Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da questa fonte.

The Formula Explained

WACC Formula: \( WACC = \frac{E}{V} \times Re + \frac{D}{V} \times Rd \times (1 - Tc) \)

Glossary of Variables

  • E: Market value of equity
  • D: Market value of debt
  • V: Total market value (E + D)
  • Re: Cost of equity
  • Rd: Cost of debt
  • Tc: Corporate tax rate

How It Works: A Step-by-Step Example

For example, if a company has a cost of equity of 8%, cost of debt of 5%, a tax rate of 21%, and the market values of equity and debt are 60% and 40% respectively, the WACC would be calculated as follows: \( WACC = 0.6 \times 0.08 + 0.4 \times 0.05 \times (1 - 0.21) \).
