The return required by equity investors. Often calculated using CAPM.
The effective interest rate a company pays on its debt.
The corporate tax rate applicable to the company’s profits.

Firm Value Formula: Firm Value = FCFF / (WACC – g)
WACC Formula: WACC = (E / (E + D)) * Re + (D / (E + D)) * Rd * (1 – t)

What is Firm Valuation Using WACC?
The process to calculate value of firm using WACC is a cornerstone of corporate finance and investment analysis. It falls under the Discounted Cash Flow (DCF) valuation method, which posits that a company’s worth is the present value of its future cash flows. The Weighted Average Cost of Capital (WACC) serves as the discount rate to bring these projected future cash flows back to their value today. This valuation represents the company’s total enterprise value, which is the value to all its capital providers, including equity shareholders and debt holders.
The Formulas to Calculate Value of Firm Using WACC
Two primary formulas are at the heart of this valuation method.
1. Weighted Average Cost of Capital (WACC)
The WACC formula calculates the blended cost of a company’s capital from both debt and equity sources.
WACC = (E / V) * Re + (D / V) * Rd * (1 - t)
Where V is the total market value of capital (E + D).
2. Gordon Growth Model for Firm Value
Once WACC is determined, it is used to discount the firm’s projected Free Cash Flow to Firm (FCFF) to find its present value. Assuming the company grows at a steady rate indefinitely, the firm’s value is calculated using the perpetuity growth model:
Firm Value = FCFF / (WACC - g)
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| FCFF | Free Cash Flow to Firm | Currency | Varies |
| E | Market Value of Equity | Currency | Varies |
| D | Market Value of Debt | Currency | Varies |
| Re | Cost of Equity | Percentage (%) | 5% – 20% |
| Rd | Cost of Debt | Percentage (%) | 2% – 10% |
| t | Corporate Tax Rate | Percentage (%) | 15% – 35% |
| g | Perpetual Growth Rate | Percentage (%) | 1% – 4% |
Practical Examples
Example 1: Tech Company
- Inputs: E = $500M, D = $100M, Re = 12%, Rd = 4%, t = 21%, FCFF = $40M, g = 3%
- WACC Calculation: WACC = (500/600)*12% + (100/600)*4%*(1-0.21) = 10% + 0.53% = 10.53%
- Firm Value Result: $40M / (10.53% – 3%) = $40M / 7.53% ≈ $531.2 Million
Example 2: Manufacturing Company
- Inputs: E = $2B, D = $1.5B, Re = 9%, Rd = 5%, t = 25%, FCFF = $250M, g = 2%
- WACC Calculation: WACC = (2/3.5)*9% + (1.5/3.5)*5%*(1-0.25) = 5.14% + 1.61% = 6.75%
- Firm Value Result: $250M / (6.75% – 2%) = $250M / 4.75% ≈ $5.26 Billion

- Review Results: The calculator instantly updates the Firm Value, WACC, and other intermediate values. The capital structure pie chart will also adjust in real-time.
Key Factors That Affect Firm Value
- Cost of Capital (WACC): A higher WACC leads to a lower firm valuation, as future cash flows are discounted more heavily.
- Free Cash Flow (FCFF): Higher and more stable FCFF directly increases the firm’s value.
- Growth Rate (g): A higher perpetual growth rate increases the terminal value, thus boosting the firm valuation. However, it must be sustainable and realistic.
- Capital Structure: The mix of debt and equity affects WACC. Debt is cheaper and offers a tax shield, but too much increases financial risk.
- Market Conditions: Interest rates, market risk premiums, and economic outlook influence both the cost of capital and growth expectations.
- Company-Specific Risk: Factors like industry position, management effectiveness, and operational efficiency impact the perceived risk and thus the cost of equity.
Frequently Asked Questions (FAQ)
Interest payments on debt are tax-deductible, which creates a “tax shield” that reduces the effective cost of debt for a company.
It’s typically calculated using the Capital Asset Pricing Model (CAPM), which involves the risk-free rate, the stock’s beta (volatility), and the equity market risk premium.
The perpetual growth rate should not exceed the long-term GDP growth rate of the country. A rate between 2-4% is generally considered reasonable.
The DCF method is best for stable, mature companies with predictable cash flows. It’s less reliable for startups or companies in volatile industries.
FCFF represents the cash flow generated by a company before any debt payments, available to all capital providers (both debt and equity holders).
No, a lower WACC is generally better as it signifies a lower cost of financing and less risk, which in turn leads to a higher valuation.
Market capitalization is just the value of equity (share price x shares outstanding). Firm value, or enterprise value, is the value of the entire company (equity + debt).
It is strongly recommended to use market values for both equity and debt for a more accurate valuation, as book values may not reflect the true current worth.
