WACC — Smart Financial Analysis
Calculate the Weighted Average Cost of Capital (WACC) using (E/V)×Re + (D/V)×Rd×(1-T). Primary discount rate for DCF valuation.
Did our AI summary help? Let us know.
WACC (Weighted Average Cost of Capital) is the average rate a company pays to finance its assets. WACC is the hurdle rate for capital budgeting—projects must earn above WACC to create value. Cost of equity is typically estimated via CAPM: Re = Rf + β(Rm - Rf). Typical corporate WACC ranges 7–12%.

WACC = (E/V)×Re + (D/V)×Rd×(1-T). It's the weighted average cost of capital—the rate a company pays to finance assets. E=equity, D=debt, V=E+D, Re=cost of equity, Rd=cost of debt, T=tax rate. Primary discount rate in DCF valuation. Typical corporate WACC 7–12%.

Key Takeaways
- • WACC = hurdle rate for capital budgeting; projects must earn above WACC
- • Use market values (not book) for E and D when calculating weights
- • Debt is cheaper after tax due to interest deductibility: Rd×(1-T)
- • Lower WACC = higher firm value; optimize capital structure to minimize WACC
Did You Know?
How Does WACC Work?
Step 1: Capital Structure Weights
E/V = equity weight, D/V = debt weight. V = E + D. Use market values for accuracy.
Step 2: Cost of Each Source
Re from CAPM or DDM; Rd from yield on debt or interest rate. Rd is adjusted by (1-T) for tax shield.
Step 3: Weighted Average
WACC = (E/V)×Re + (D/V)×Rd×(1-T). Each source's cost is weighted by its share of total capital.

Frequently Asked Questions
What is WACC?
WACC (Weighted Average Cost of Capital) is the average rate a company pays to finance its assets. Formula: WACC = (E/V)×Re + (D/V)×Rd×(1-T), where E=equity value, D=debt value, V=E+D, Re=cost of equity, Rd=cost of debt, T=tax rate. It serves as the primary discount rate in DCF valuation.
Why is WACC important?
WACC is the hurdle rate for capital budgeting—projects must earn above WACC to create value. It's the discount rate in DCF models for company valuation. Lower WACC means cheaper capital and higher firm value. CFOs use it to optimize capital structure.
How to calculate cost of equity?
Cost of equity is typically estimated via CAPM: Re = Rf + β(Rm - Rf). Rf = risk-free rate, β = stock beta, Rm = market return. Dividend discount models and build-up methods are alternatives. Expect 8–15% for typical corporations.
What is a good WACC?
Typical corporate WACC ranges 7–12%. Tech and growth firms often 10–14%; utilities 5–8%. Lower is better—it means cheaper capital. Compare to industry peers and your ROIC; value is created when ROIC > WACC.
WACC vs discount rate?
WACC is the standard discount rate for unlevered or firm-level cash flows in DCF. For equity cash flows, use cost of equity. For project-specific risk, adjust WACC up or down. WACC reflects the firm's overall cost of capital.
How do taxes affect WACC?
Interest on debt is tax-deductible, so after-tax cost of debt = Rd×(1-T). The (1-T) term creates a tax shield—higher tax rates make debt relatively cheaper. This is why leveraged firms often have lower WACC than all-equity firms.
