What is Reverse Discounted Cash Flow Valuation?
Reverse Discounted Cash Flow (Reverse DCF) valuation starts with the company's current stock price and works backwards to determine the Revenue Growth required to justify that price.
Unlike a Standard DCF, which estimates Fair Value from assumed future performance, Reverse DCF identifies the growth expectations implied by the current market valuation.
The result is the Implied Revenue Growth Rate—the initial Revenue Growth required for the DCF valuation to reproduce the current market price under the selected assumptions.
Reverse DCF Formulas
Reverse DCF uses the standard DCF framework, but instead of estimating a fair value, it solves for the Revenue Growth Rate that makes the calculated DCF value equal today's market price.
How the Reverse DCF Valuation Works
The model repeatedly adjusts the initial Revenue Growth assumption until the calculated Enterprise Value matches the Target Enterprise Value implied by today's stock price.
Key Model Assumptions
• Starting Revenue and Free Cash Flow use trailing twelve-month (TTM) values when available, with the latest annual values used as a fallback.
• Revenue is projected using the implied initial Revenue Growth Rate, which gradually converges toward the Terminal Growth Rate.
• Free Cash Flow is estimated as projected Revenue multiplied by the projected Free Cash Flow Margin.
• The Free Cash Flow Margin gradually moves toward a normalized Target Free Cash Flow Margin based on the median of up to the five most recent valid historical Free Cash Flow Margins.
• Future Free Cash Flows are discounted using the Weighted Average Cost of Capital (WACC).
• 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.
• The model repeatedly adjusts the initial Revenue Growth Rate until the calculated Enterprise Value matches the Enterprise Value implied by today's market price.
Step 1 — Calculate the Target Enterprise Value
Reverse DCF starts with today's market price rather than estimating a Fair Value. The Current Share Price is multiplied by Shares Outstanding to determine the Market Equity Value.
Net Debt is then added to calculate the Target Enterprise Value. This is the Enterprise Value that the projected future cash flows must match.
Step 2 — Project Revenue and Free Cash Flow
Revenue Growth is the unknown assumption that the Reverse DCF seeks to determine. Each tested initial Revenue Growth Rate creates a different projected Revenue path.
Revenue Growth gradually converges toward the Terminal Growth Rate, while the Free Cash Flow Margin moves toward a normalized Target Free Cash Flow Margin based on the median of up to the five most recent valid historical Free Cash Flow Margins.
Projected Revenue is then combined with the projected Free Cash Flow Margin to estimate future Free Cash Flows.
Step 3 — Calculate WACC and Terminal Value
WACC is used to discount future Free Cash Flows back to their present value. After the explicit forecast period, Free Cash Flow is assumed to grow at the Terminal Growth Rate.
The Gordon Growth formula converts these continuing cash flows into a Terminal Value. Both WACC and Terminal Growth therefore influence the Implied Revenue Growth produced by the Reverse DCF.
Step 4 — Calculate the Enterprise Value
The projected Free Cash Flows and Terminal Value are discounted back to their present values using WACC. Together, they determine the Enterprise Value produced by the currently tested Revenue Growth assumption.
This calculated Enterprise Value is compared with the Target Enterprise Value derived from the current stock price in Step 1.
If the calculated Enterprise Value is below the target, the tested Revenue Growth is too low. If it is above the target, the tested Revenue Growth is too high.
Step 5 — Find the Matching Revenue Growth
The model repeatedly adjusts the initial Revenue Growth assumption and recalculates the complete DCF.
A binary search progressively narrows the range of possible Revenue Growth Rates until the calculated Enterprise Value closely matches the Target Enterprise Value.
Step 6 — Determine the Implied Revenue Growth
Once the calculated Enterprise Value closely matches the Target Enterprise Value, the corresponding initial Revenue Growth Rate becomes the Implied Revenue Growth.
This represents the initial Revenue Growth required for the model to reproduce today's market valuation. The growth rate then gradually converges toward the Terminal Growth Rate over the forecast period.
The result depends on assumptions such as WACC, Terminal Growth, the forecast period and the projected Free Cash Flow Margin.
