When it comes to accurately valuing a privately held business, the Discounted Cash Flow (DCF) method stands out as one of the most technically sound and widely respected approaches. It focuses not on past performance, but on the future earning potential of a business—making it particularly useful for owners, investors, and financial professionals interested in forward-looking valuation models.

In this guide, we’ll break down the core mechanics of the DCF method, explain its assumptions, and demonstrate how business owners can estimate their company’s value using this method—even without a finance degree—through our Free Business Valuation Calculator.

What Is the Discounted Cash Flow (DCF) Method?

The DCF method is a valuation technique based on the principle of time value of money (TVM). According to TVM, a dollar today is worth more than a dollar tomorrow due to its earning potential. The DCF method captures this by discounting future expected cash flows back to their present value.

In practical terms, this method answers the question:

What is my business worth today based on the cash it is expected to generate in the future?

DCF in the Context of Business Valuation

DCF is especially relevant when:

• The business has predictable cash flow streams.

• There are limited market comparables.

• The owner or buyer is focused on intrinsic value rather than just market sentiment.

It is commonly used in valuations for mergers & acquisitions, investment analysis, litigation, estate planning, and exit strategy development.

Core Components of a Valuation With Discounted Cash Flow (DCF) method

A proper DCF model consists of three critical components:

1. Forecasted Cash Flows

This is the projected free cash flow to the firm (FCFF)—the amount of cash a business is expected to generate after accounting for operating expenses, taxes, and reinvestment needs. These projections typically span 5 to 10 years.

Key inputs include:

• Revenue growth rate

• Operating margins

• Capital expenditures

• Changes in working capital

• Effective tax rate

In many cases, EBITDA or Net Operating Profit After Tax (NOPAT) is used as a starting point.

2. Terminal Value

After the projection period, it becomes increasingly difficult to estimate individual year cash flows. To account for value beyond the forecast window, a terminal value is calculated. This represents the ongoing value of the business in perpetuity or under an assumed exit scenario.

Common methods:

• Gordon Growth Model: Assumes perpetual growth at a constant rate.

• Exit Multiple Method: Applies a valuation multiple to Year 5 or Year 10 cash flows.

3. Discount Rate (WACC)

The discount rate reflects the riskiness of the cash flows. In business valuation, this is often the Weighted Average Cost of Capital (WACC)—a blended rate combining the cost of equity and cost of debt.

Higher-risk businesses or industries will typically have a higher discount rate, reducing the present value of expected cash flows.

Using Our Free Calculator to Perform a Discounted Cash Flow Valuation

At Los Angeles Business Valuations, we’ve built a user-friendly calculator that automates the Discounted Cash Flow (DCF) method process while still letting users enter their own assumptions. This bridges the gap between DIY and professional-grade valuations.

How It Works:

1. Input Financial Data
   Enter your current or projected revenue, EBITDA, or net income. If you have growth assumptions, you can plug those in too.

2. Adjust Growth and Forecast Period
   Define how many years of cash flow you want to forecast—typically 5 to 7 is standard. You can also specify different growth rates for each year.

3. Set Discount Rate
   Choose a discount rate that reflects your business’s risk profile. If unsure, we provide industry benchmarks to guide your input.

4. Terminal Value Estimation
   The calculator automatically applies the Gordon Growth Model with a customizable long-term growth rate. Alternatively, you can use a multiple of your Year 5 cash flow.

5. Get Your Business Value
   The result shows the total present value of your business, broken into forecasted cash flows and terminal value. This is the DCF-derived estimate of intrinsic value.

Example: Valuing a Small Business with $500K Annual EBITDA

Let’s assume:

• EBITDA grows at 5% annually for 5 years

• Discount rate (WACC) is 12%

• Terminal growth rate is 3%

Our calculator will:

1. Project cash flows for 5 years

2. Discount each year’s EBITDA to present value

3. Add terminal value discounted to today

4. Provide a total estimated business value

This approach is more precise than applying a 3x or 5x EBITDA multiple, especially for businesses with irregular growth, reinvestment needs, or high capital risk.

Advantages of the DCF Method

✅ Forward-Looking: Unlike historical methods, DCF focuses on your future earning potential.
✅ Customizable: Adjust inputs based on real assumptions.
✅ Logical: Grounded in finance theory used by professionals worldwide.
✅ Better Than Multiples: While rule-of-thumb multiples are helpful, they ignore the specific cash flow power of your business.

Limitations to the Discounted Cash Flow Method

❌ Highly Sensitive: Small changes in discount rate or growth rate can cause big valuation swings.
❌ Requires Forecasts: It assumes you can reasonably estimate future performance.
❌ Not Ideal for Unstable Businesses: Businesses with unpredictable cash flows may require other valuation approaches or hybrid models.

Conclusion: Use the DCF Method to Understand Your Business’s True Worth

The DCF method offers a clear window into the intrinsic value of your company—one based not just on what you’ve done, but what you’re capable of in the future. It’s ideal for serious business owners preparing for strategic decisions: raising capital, planning an exit, or evaluating a buy-sell agreement.

And now, thanks to our intuitive platform, you don’t need to build spreadsheets or hire an analyst just to get a reliable DCF estimate.
