Description

The WACC Calculator helps businesses determine their Weighted Average Cost of Capital - the blended rate a company pays for its capital. Essential for investment decisions and financial analysis.

What Is It?

This financial tool calculates the minimum return a company must earn to satisfy its investors by:

  • Combining debt and equity costs

Key Formula

WACC = (E/V × Re) + (D/V × Rd × (1 - Tc))
Where:

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