How do you calculate WACC for a private company?

• A. By directly using market beta and market cap values
• B. By estimating based on audits or comparisons to public companies
• C. WACC cannot be estimated for private companies
• D. By using dividend discount model

Answer: (B)

When valuing a private company, you don’t have observable market data like a beta or market cap, so you derive WACC by using proxies from public comparables and adjusting for the private firm’s specifics. Start with the cost of equity from comparable public companies: take their levered beta, un-lever it to remove debt, then relever to reflect the private firm’s target debt level, and apply CAPM (cost of equity ≈ risk-free rate + equity beta × market risk premium). For the cost of debt, use the median yield or interest rate on debt of similar public firms, adjusted for the private firm’s credit risk, or use the private firm’s own borrowing rates if available. Since market values of debt and equity aren’t directly observable for a private firm, use target or adjusted book values to set the weights of debt and equity. Then compute WACC as: WACC = (E/(E+D)) × Cost of Equity + (D/(E+D)) × Cost of Debt × (1 − tax rate). Using estimates from public comparables is the practical approach because private firms lack the market data needed for a direct calculation. Relying on a dividend discount model isn’t appropriate for WACC, and assuming WACC cannot be estimated ignores standard methods for private-company valuation.
