Editor’s pick Hands-on review
US industry-level WACC dataset compiled by Prof. Aswath Damodaran. Includes sector betas, cost of equity, cost of debt (pre/after-tax), capital structure weights, and industry counts. Updated annually (January snapshot). Best used as a sector baseline; company-specific WACC should adjust for firm capital structure, tax, and risk. See 'Cost of Capital Central' for methodology deep-dives.
