Firm Value Calculator (Using WACC)
Determine a company’s total value by discounting its future cash flows.
Enter the most recent annual Free Cash Flow to Firm in dollars ($).
Enter the WACC as a percentage (%). This is the firm’s average cost of capital.
Enter the expected constant growth rate of FCFF as a percentage (%).
What is Calculating Firm Value Using WACC?
Calculating firm value using the Weighted Average Cost of Capital (WACC) is a fundamental valuation method used in corporate finance. It falls under the Discounted Cash Flow (DCF) model category. The core idea is that a company’s total value (its “firm value” or “enterprise value”) is the present value of all its expected future cash flows.
To do this, we first project the company’s Free Cash Flow to the Firm (FCFF), which represents the cash generated by the business for all its capital providers, both debt and equity holders. Then, we discount these cash flows back to today’s value using the WACC as the discount rate. The WACC represents the blended, average rate of return that the company must pay to its investors (shareholders and creditors). A related tool you might find useful is our Cost of Equity Calculator.
The Firm Value Formula and Explanation
The primary formula used for calculating firm value in a stable-growth phase is a perpetuity formula known as the Gordon Growth Model. This model is ideal when a company is expected to grow at a steady, constant rate forever.
Firm Value = FCFF₁ / (WACC – g)
Where:
- FCFF₁ is the Free Cash Flow to the Firm expected in the first year of the terminal period.
- WACC is the Weighted Average Cost of Capital.
- g is the perpetual (or constant) growth rate of the FCFF.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| FCFF | Free Cash Flow to Firm: The cash generated for all capital providers after all operating expenses and investments. | Currency ($) | Varies widely by company size |
| WACC | Weighted Average Cost of Capital: The average rate of return a company is expected to pay to its security holders to finance its assets. | Percentage (%) | 5% – 15% |
| g | Perpetual Growth Rate: The rate at which the firm’s FCFF is expected to grow indefinitely. | Percentage (%) | 1% – 4% (must be less than the WACC) |
Practical Examples
Example 1: Mature Manufacturing Company
Imagine a stable manufacturing company with predictable cash flows. You have the following inputs:
- Inputs:
- Free Cash Flow to Firm (FCFF): $10,000,000
- WACC: 8.0%
- Perpetual Growth Rate (g): 2.5%
- Calculation:
- WACC – g = 8.0% – 2.5% = 5.5%
- Firm Value = $10,000,000 / 0.055
- Result:
- The calculated firm value is approximately $181,818,182.
Example 2: Established Tech Firm
Consider a well-established tech company with solid market share.
- Inputs:
- Free Cash Flow to Firm (FCFF): $50,000,000
- WACC: 10.5%
- Perpetual Growth Rate (g): 3.0%
- Calculation:
- WACC – g = 10.5% – 3.0% = 7.5%
- Firm Value = $50,000,000 / 0.075
- Result:
- The calculated firm value is approximately $666,666,667. Another valuable method to explore is our DCF Valuation Calculator for more detailed projections.
How to Use This Firm Value Calculator
This calculator simplifies the process of calculating firm value using wacc. Follow these steps for an accurate valuation:
- Enter Free Cash Flow to Firm (FCFF): Input the company’s most recent annual FCFF. This figure represents the cash available to all investors after business expenses and reinvestments.
- Enter WACC: Provide the company’s Weighted Average Cost of Capital as a percentage. This is the discount rate that reflects the riskiness of the company’s cash flows.
- Enter Perpetual Growth Rate (g): Input the sustainable, long-term growth rate you expect for the company’s cash flows. This rate should be realistic and typically not exceed the long-term GDP growth rate of the economy.
- Calculate and Interpret: Click the “Calculate Firm Value” button. The primary result is the total enterprise value of the firm. The tables provide a breakdown of your inputs and a sensitivity analysis showing how the valuation changes with slight adjustments to your assumptions.
Key Factors That Affect Firm Value
The valuation derived from the WACC model is sensitive to several key factors. Understanding them is crucial for a sound analysis.
- FCFF Projections: The foundation of the valuation. Overly optimistic or pessimistic cash flow projections will directly lead to an over- or under-valuation.
- WACC (Discount Rate): A higher WACC signifies higher perceived risk and will result in a lower firm value, as future cash flows are discounted more heavily. Learn more by using a WACC Calculator.
- Perpetual Growth Rate (g): This is a highly sensitive input. A small change in ‘g’ can lead to a significant change in firm value. It must be a long-term, sustainable rate.
- Market Conditions: Broader economic factors, interest rates, and market risk premiums all influence the WACC and, therefore, the valuation.
- Company-Specific Risk: Factors like competitive advantages, management strength, and operational efficiency affect both the FCFF and the risk profile, which is captured in the WACC.
- Capital Structure: The mix of debt and equity a company uses affects its WACC. Typically, debt is cheaper than equity, so changes in capital structure can alter the WACC and valuation.
Frequently Asked Questions (FAQ)
1. What is Free Cash Flow to Firm (FCFF)?
FCFF is the cash a company generates from its operations after paying for operating expenses and investments in working capital and fixed assets. It’s the cash flow available to all capital providers: equity holders, debt holders, and preferred stockholders.
2. Why must WACC be greater than the growth rate (g)?
Mathematically, if ‘g’ were greater than or equal to WACC, the denominator in the formula (WACC – g) would be zero or negative, resulting in an infinite or meaningless negative value. Conceptually, a company cannot grow faster than its cost of capital indefinitely in a stable state. Such high growth is unsustainable in the long run.
3. What is a “good” WACC?
There is no single “good” WACC. It depends heavily on the industry, company size, geographic location, and overall market risk. A mature utility company might have a WACC of 4-6%, while a high-growth tech startup could have a WACC of 15% or more to reflect its higher risk.
4. How accurate is the WACC model for calculating firm value?
The model’s accuracy is entirely dependent on the quality of its inputs. It is a powerful tool but provides an estimate, not a certainty. It’s best used to establish a reasonable valuation range. For more detailed analysis, consider a financial modeling guide.
5. Is Firm Value the same as Equity Value?
No. Firm Value (or Enterprise Value) is the value of the entire company to all stakeholders. To get to Equity Value (the value available only to shareholders), you must subtract the market value of debt and add any cash from the Firm Value.
6. Where does the perpetual growth rate (g) come from?
The growth rate ‘g’ is an estimate of the company’s long-term, stable growth. It is often benchmarked against the long-term expected growth of the economy (GDP) or the rate of inflation, typically falling in the 2-4% range.
7. What is the difference between FCFF and FCFE?
Free Cash Flow to Firm (FCFF) is the cash available to all capital providers (debt and equity). Free Cash Flow to Equity (FCFE) is the cash available only to equity shareholders after all debt obligations have been paid.
8. Can this calculator be used for startups?
This specific perpetuity model is best for mature, stable companies. Valuing startups is more complex as they lack stable cash flows and have unpredictable growth. Other methods, like venture capital valuation or a multi-stage DCF, are often more appropriate. Our business valuation calculator offers more methods.
