WACC

The Weighted Average Cost of Capital (WACC) represents the average cost of financing a company's debt and equity. There are two approches to calculating it, one based on the "Build-up" approach, the other on the Capital Assets Pricing Model (CAPM) approach.

WACC = Ce × E + Cd × D

where Cd is the after-tax cost of debt, E and D the proportion of equity and debt in a firm based on market value, and Ce is the cost of equity, which, using the CAPM approach, is calculated with:

Ce = Rf + β(Rm)+Rs + Risk + Firm Risk

where Rf is risk-free rate, Rm is the market premium, Rs is the company size premium, Risk the country risk premium, Firm Risk the firm-specific risk and β is a measure of the systematic risk, usually of the industry sector, in comparison to the market as a whole.

β for various sectors of US industry is available with:
