WACC (Weighted Average Cost of Capital) is the average rate a company pays to finance its assets, weighted by the proportion of debt and equity in its capital structure. It represents the minimum return a company must earn on its existing asset base to satisfy its creditors, owners, and other providers of capital.

How do you calculate WACC?

WACC is calculated as: WACC = (E/V × Re) + (D/V × Rd × (1-T)), where E is the market value of equity, D is the market value of debt, V is total value (E+D), Re is cost of equity (typically from CAPM), Rd is cost of debt, and T is the corporate tax rate.

WACC varies significantly by industry and company risk profile. Typical ranges are 6-8% for stable blue-chip companies, 8-12% for mid-cap growth companies, and 12%+ for high-risk or early-stage companies. Lower WACC indicates cheaper capital and generally results in higher DCF valuations.

What is WACC and why is it important?

WACC (Weighted Average Cost of Capital) represents the average rate a company must pay to finance its assets. It's crucial for DCF valuation, capital budgeting decisions, and assessing whether investments will generate returns above the cost of capital.

How do I calculate cost of equity?

Cost of equity is calculated using the CAPM formula: Risk-Free Rate + (Beta × Market Risk Premium). We automatically fetch the 10-year Treasury rate from FRED API, use company beta from financial data, and apply the current market risk premium (typically 4-6%).

Where do you get the risk-free rate from?

We fetch the 10-year Treasury Constant Maturity Rate directly from the Federal Reserve Economic Data (FRED) API. This is updated daily and represents the most widely accepted risk-free rate for US equity valuation.

How is the cost of debt calculated?

Pre-tax cost of debt is estimated by adding a credit spread to the risk-free rate. The credit spread is based on the company's interest coverage ratio, which maps to a synthetic credit rating (AAA to D). The after-tax cost of debt accounts for the tax shield benefit.

Can I manually adjust the WACC inputs?

Yes! While we auto-populate all inputs with company data and market rates, you can manually adjust any parameter including beta, tax rate, risk-free rate, and market risk premium to perform sensitivity analysis or use your own estimates.
