Projecting Free Cash Flows for Business Valuation
Projecting free cash flows (FCF) is a cornerstone of Discounted Cash Flow (DCF) analysis, a fundamental valuation method in corporate finance. By forecasting the cash a company is expected to generate after accounting for operating expenses and capital expenditures, we can estimate its intrinsic value. This process involves understanding a company's historical performance, industry trends, and future growth prospects.
Understanding Free Cash Flow
Free Cash Flow represents the cash available to a company's investors (both debt and equity holders) after all operating expenses and investments in capital assets have been paid. There are two primary types: Free Cash Flow to Firm (FCFF) and Free Cash Flow to Equity (FCFE). For DCF valuation, FCFF is more commonly used as it represents the cash flow available to all capital providers before any debt payments.
FCFF is the cash available to all capital providers.
Free Cash Flow to Firm (FCFF) is calculated by taking Net Operating Profit After Tax (NOPAT) and adding back Depreciation & Amortization, then subtracting Capital Expenditures and the change in Working Capital.
The formula for FCFF is often expressed as: FCFF = NOPAT + Depreciation & Amortization - Capital Expenditures - Change in Working Capital. NOPAT is calculated as EBIT * (1 - Tax Rate). Depreciation and amortization are non-cash expenses, so they are added back. Capital expenditures (CapEx) are investments in long-term assets, and changes in working capital reflect investments in short-term assets and liabilities.
The Projection Process
Projecting free cash flows involves several key steps, each requiring careful analysis and assumptions. These steps typically span a forecast period, often 5-10 years, followed by a terminal value calculation.
Step 1: Projecting Revenue
Revenue projection is the foundation. This involves analyzing historical sales growth, market size, competitive landscape, pricing strategies, and macroeconomic factors. Common methods include growth rate assumptions, market share analysis, and unit sales forecasts.

Step 2: Projecting Operating Expenses and NOPAT
Once revenue is projected, operating expenses (Cost of Goods Sold, Selling, General & Administrative expenses) are forecasted. These are often projected as a percentage of revenue or based on historical trends. Net Operating Profit After Tax (NOPAT) is then derived from Earnings Before Interest and Taxes (EBIT) by applying the company's effective tax rate.
Step 3: Projecting Capital Expenditures (CapEx)
CapEx represents investments in property, plant, and equipment. Projections should consider maintenance CapEx (to sustain existing operations) and growth CapEx (to expand capacity or enter new markets). Historical CapEx as a percentage of revenue or sales can be a starting point, adjusted for future growth plans.
Step 4: Projecting Changes in Working Capital
Changes in working capital (e.g., accounts receivable, inventory, accounts payable) are critical. An increase in working capital typically consumes cash, while a decrease generates cash. These are often projected based on historical relationships with revenue or cost of goods sold.
The calculation of Free Cash Flow to Firm (FCFF) involves several key components derived from the income statement and balance sheet. It starts with Net Operating Profit After Tax (NOPAT), which is EBIT adjusted for taxes. To this, we add back non-cash expenses like Depreciation and Amortization. Then, we subtract investments in long-term assets (Capital Expenditures) and any increases in short-term operating assets relative to short-term operating liabilities (Change in Working Capital). This process isolates the cash generated by the core operations of the business available to all investors.

Step 5: Calculating Terminal Value
Since it's impossible to forecast cash flows indefinitely, a terminal value is calculated to represent the value of the company beyond the explicit forecast period. Common methods include the Gordon Growth Model (perpetual growth) and the Exit Multiple method.
The accuracy of your DCF valuation hinges on the quality and reasonableness of your free cash flow projections and terminal value assumptions.
Key Considerations and Best Practices
When projecting free cash flows, it's essential to maintain consistency in assumptions, perform sensitivity analysis, and understand the drivers of cash flow for the specific industry and company.
| Projection Component | Key Drivers | Common Projection Methods |
|---|---|---|
| Revenue | Market size, competition, pricing, economic growth | Growth rates, market share, unit sales |
| Operating Expenses | Revenue levels, efficiency, cost management | Percentage of revenue, historical trends |
| Capital Expenditures | Asset age, growth strategy, industry norms | Percentage of revenue, historical CapEx, planned investments |
| Working Capital | Sales cycle, inventory management, payment terms | Days Sales Outstanding (DSO), Days Inventory Outstanding (DIO), Days Payables Outstanding (DPO) |
Sensitivity analysis involves changing key assumptions (e.g., growth rate, discount rate) to see how the valuation changes. This helps understand the range of possible outcomes and the most impactful variables.
