WACC Calculator

WACC is the blended return a company has to earn to keep everyone who funds it whole. Enter the market value of equity and debt, the cost of each and the corporate tax rate, and you get the weighted rate along with the two weights, the after-tax cost of debt and what each side contributes. A second mode builds the cost of equity from CAPM first, out of a risk-free rate, a beta and a market risk premium. Market values and the cost of equity are estimates rather than quoted prices, so the answer is a range and not a single figure.
