What is Discounted Cash Flow Valuation?
Discounted Cash Flow (DCF) valuation is one of the most widely used methods for estimating the intrinsic value of a business. Rather than relying on the current market price, it estimates what a company is worth based on its ability to generate Free Cash Flow in the future.
The underlying principle is that a business is worth the cash it can generate for investors over its lifetime. Because money received in the future is worth less than money received today, those future cash flows must be converted into today's value.
DCF valuation is particularly useful because it focuses on the company's underlying economics rather than short-term market sentiment. However, the estimated value depends heavily on assumptions about future growth, profitability and risk.
DCF Formulas
These formulas summarize the main valuation logic behind the model. The detailed calculations are explained step by step below.
How the DCF Model Works
Discounted Cash Flow valuation estimates intrinsic value by projecting future free cash flows, discounting those cash flows back to today, adding the present value of the terminal value, adjusting for net debt or net cash, and converting the result into a fair value per share.
Key Model Assumptions
• Starting Revenue uses trailing twelve-month (TTM) data when four consecutive quarterly periods are available; otherwise, the latest annual Revenue is used.
• Free Cash Flow is estimated as projected Revenue multiplied by the projected Free Cash Flow Margin.
• Starting Free Cash Flow uses trailing twelve-month (TTM) data when four consecutive quarterly periods are available; otherwise, the latest annual Free Cash Flow is used. If the resulting Free Cash Flow is negative or materially inconsistent with recent history, the average of the last three positive annual Free Cash Flow values is used.
• The Target Free Cash Flow Margin is based on the median of up to the five most recent valid historical Free Cash Flow Margins.
• Revenue Growth gradually converges toward the Terminal Growth Rate as the company matures.
• Future Free Cash Flows are discounted using WACC, reflecting both the Cost of Equity and the after-tax Cost of Debt.
• The Risk-Free Rate is based on the U.S. 10-Year Treasury yield published by the Federal Reserve Board.
• Terminal Growth represents the company's sustainable long-term growth rate after the explicit forecast period.
• Enterprise Value is adjusted for Net Debt or Net Cash to estimate Equity Value.
Step 1 — Calculate Free Cash Flow
Free Cash Flow represents the cash generated by the business after accounting for Capital Expenditures required to maintain and expand its operations. Because it reflects cash that is potentially available to investors, it forms the foundation of a Discounted Cash Flow valuation.
Companies that generate strong and sustainable Free Cash Flow are generally better positioned to create value for investors.
Step 2 — Estimate Future Free Cash Flow Margin
Free Cash Flow Margin measures how efficiently a company converts Revenue into cash. Businesses with higher margins are able to generate more cash in relation to their Revenue, increasing the value of future cash flows.
Since profitability changes over time, the model gradually transitions from the Starting Free Cash Flow Margin toward a sustainable long-term margin.
Step 3 — Forecast Revenue
The forecast starts from the company's current Revenue base, using trailing twelve-month (TTM) Revenue when available and the latest annual Revenue as a fallback.
Revenue Growth determines how quickly the business is expected to expand over time and influences its future cash-generating potential. As companies mature, high growth rates generally become more difficult to sustain.
The Base Revenue Growth Rate is derived from the company's historical Compound Annual Growth Rate (CAGR). The selected scenario adjusts this Base rate, which then gradually converges toward the Terminal Growth Rate over the forecast period.
Step 4 — Forecast Future Free Cash Flow
Future Free Cash Flow represents the economic benefit expected from the company's future operations. It combines expectations about business growth with assumptions about operating efficiency.
For each forecast year, projected Revenue is multiplied by the corresponding Free Cash Flow Margin to estimate the cash the business is expected to generate.
These projected cash flows form the basis of the entire valuation because they represent the future benefits investors expect to receive.
Step 5 — Discount Future Free Cash Flows
Because investors require compensation for both the time value of money and investment risk, future cash flows must be converted into today's value. The model does this by discounting each projected Free Cash Flow using the company's WACC, which represents its overall required rate of return.
The present values of all forecast Free Cash Flows are then added together. This produces the complete present value of all Forecast Free Cash Flows used to calculate Enterprise Value.
Step 6 — Estimate Terminal Value
Most companies are expected to continue operating long after the explicit forecast period ends. Terminal Value captures the value of those future cash flows beyond the detailed forecast.
The Terminal Value assumes that Free Cash Flow continues growing at a stable and sustainable long-term Terminal Growth Rate.
Because the Terminal Value represents value at the end of the forecast period, it also must be discounted back to its present value using WACC.
Step 7 — Calculate Enterprise Value
Enterprise Value represents the value of the company's operating business independent of how it is financed. It is obtained by combining the present value of forecast Free Cash Flows with the present value of the Terminal Value, capturing both the explicit forecast period and the company's long-term cash-generating potential.
Because it excludes financing decisions, Enterprise Value allows companies with different debt levels to be compared on a consistent basis.
Step 8 — Calculate Equity Value
Shareholders are entitled only to the value remaining after outstanding debt has been considered. Likewise, excess cash increases the value attributable to equity investors.
This adjustment converts the value of the operating business into the value of shareholders' ownership.
Step 9 — Calculate Fair Value per Share
Dividing Equity Value by Shares Outstanding converts the value of the entire company into an estimated value for one individual share.
Comparing this estimate with the current market price helps investors assess whether market expectations appear optimistic, pessimistic or broadly consistent with the model's assumptions.
