A Comparison of the Weighted-Average Cost of Capital and Equity-Residual Approaches to Valuation

This technical note compares two methods of treating debt usage in discounted-cash-flow valuation of investment projects or companies. The note demonstrates that the approach using weighted average cost of capital (WACC) and the approach using equity residual (ER) yield equivalent results if consistent assumptions are used. General features are illustrated with specific examples, including a spreadsheet.
