What Is a Reverse DCF?
A standard DCF model works forward: you input a growth rate, discount it back at your required return, and arrive at an intrinsic value. A reverse DCF flips this. You start with the current stock price and ask: what annual free cash flow growth rate would make this price exactly right? The answer is the implied growth rate — the market's embedded expectation about the company's future.
The reverse DCF is often more honest than a standard DCF because it forces a specific question: “Is what the market is pricing in actually achievable?” Rather than arguing over what a stock is “worth,” you ask whether the growth expectation built into today's price is realistic given the company's history, competitive position, and industry trajectory. If the implied rate is 35% and the company has grown FCF at 12% historically, you have a concrete basis for concern. If the implied rate is 8% and the company has averaged 18%, you have a concrete basis for optimism.
How to Interpret the Results
Aggressive: The implied growth rate is more than 50% above the company's historical FCF CAGR. The stock is priced for above-historical execution — if growth decelerates to trend, the stock would need to re-rate lower to be fairly valued. This isn't necessarily a sell signal (companies do accelerate), but it means the margin of error is thin.
Reasonable: The implied growth rate is in line with what the company has historically delivered. The market isn't pricing in acceleration — it's pricing in continuation. Whether this is a buy, hold, or sell depends on whether you think historical growth will continue, improve, or deteriorate.
Conservative: The implied growth rate is below historical FCF CAGR. The market is pricing in deceleration. If you believe the company can sustain historical growth, the stock may be undervalued. Check whether there's a known catalyst for deceleration (competitive pressure, regulation, cyclical peak) before concluding it's cheap.
The Role of WACC in the Calculation
The implied growth rate is highly sensitive to the discount rate (WACC). A higher WACC lowers the present value of future cash flows, which means a higher growth rate is needed to justify the same current price. Use the WACC calculator to derive a defensible rate from the company's actual capital structure — equity beta, cost of debt, and debt-to-equity ratio — rather than guessing. The sensitivity table in this calculator shows implied growth at ±1% WACC so you can see how much your conclusion changes with different discount rate assumptions.
For most large-cap US equities, a WACC of 8–10% is standard. Use 11–13% for smaller, more volatile, or capital-intensive companies. See the discounted cash flow guide for a detailed walkthrough of how each assumption affects the model.
How to use this reverse DCF calculator
Load a ticker
Type any US ticker and click Load. The calculator pulls current price, TTM free cash flow, shares outstanding, and historical FCF growth from Yahoo Finance. All data is live — no stale numbers.
Set your WACC
Adjust the discount rate slider. 8–10% for large-cap US equities, 11–13% for smaller or riskier businesses. Use the WACC calculator to derive a precise number from beta and capital structure.
Read the implied growth rate
The large number is the annual FCF growth rate the market is pricing in over your chosen projection horizon. The verdict badge — Aggressive, Reasonable, or Conservative — compares it to the company's historical growth.
Form a view
Ask: can this company actually deliver the implied growth rate? If yes, the stock is fairly valued or cheap. If no — or if you're uncertain — the stock carries risk. Pair with a full DCF analysis to stress-test multiple scenarios.
Reverse DCF vs. standard DCF
How the back-solver works
The reverse DCF uses a binary search algorithm. It tries a candidate growth rate, computes the present value of the resulting FCF stream (plus terminal value using the Gordon Growth Model), and compares it to the current market cap. If the model value is too high, the growth rate is reduced; if too low, it's raised. After ~300 iterations, the algorithm converges on the implied growth rate to within 0.001%.
Terminal value uses the Gordon Growth Model: TV = FCF_final × (1 + g) / (WACC − g), where g is the terminal growth rate. The sensitivity table uses the exit multiple approach (TV = FCF_final × multiple) to show how different exit valuations affect the implied growth assumption.
When to use reverse DCF vs. standard DCF
Use a standard DCF calculator when you have a specific growth thesis and want to calculate intrinsic value — buying something you believe is undervalued. Use the reverse DCF when evaluating whether a stock's current price is reasonable — especially for high-multiple stocks where the question isn't “is it cheap?” but “is the implied growth realistic?”
The reverse DCF is particularly useful for growth stocks (NVDA, TSLA, AMZN) where traditional P/E multiples are high and the bull case rests entirely on sustained above-average FCF growth. It puts a concrete number on that expectation.
Historical FCF growth: what it means
The historical FCF CAGR is computed from the last 3–4 years of annual cashflow statements (operating cash flow minus capex). It's the geometric annualized growth rate — a fair measure of sustained FCF growth, less skewed by a single exceptional year than a simple average.
A company's historical FCF growth is not a guarantee of future performance, but it's the best available anchor. If the implied rate is 2× the historical rate, the market is betting on acceleration. If it's 0.5×, the market is pricing in deceleration. Your job is to decide which scenario is more likely.
Limitations of reverse DCF
The reverse DCF requires positive free cash flow — it can't be run on pre-profit companies or those with negative FCF (negative FCF has no meaningful PV). It also assumes the current price is set by rational agents with a long-term perspective, which may not always hold during periods of speculation or panic.
For cyclical businesses at peak or trough FCF, the implied growth rate may be misleading — normalize FCF first. And like all DCF models, the output is only as good as the WACC assumption. Use the sensitivity table to understand how your conclusion changes across a range of discount rates.
Frequently asked questions
What is the reverse DCF formula?
The reverse DCF doesn't have a closed-form formula — it's solved numerically. You set up the standard DCF equation: Market Cap = Σ [FCF₀ × (1+g)ᵗ / (1+WACC)ᵗ] + Terminal Value / (1+WACC)ⁿ, then use binary search to find the growth rate g that satisfies it.
What does 'implied growth rate' mean?
The implied growth rate is the annual FCF growth the current stock price assumes. If a stock requires 25% annual FCF growth to be 'fairly valued,' that's its implied growth rate. If you think 25% is unrealistic, the stock looks overvalued. If you think it's achievable, it looks fairly priced.
Why does this show an error for some tickers?
The reverse DCF requires positive trailing twelve-month free cash flow. Companies with negative FCF — early-stage, pre-profit, turnaround, or capital-intensive businesses — will trigger an error because there's no positive cash flow stream to discount.
How is terminal value calculated?
The main calculation uses the Gordon Growth Model: TV = FCF_final × (1 + terminalGrowthRate) / (WACC − terminalGrowthRate). The sensitivity table uses an exit multiple approach: TV = FCF_final × multiple. Both are common methods — the Gordon Growth Model is more conservative for stable businesses.
Why is WACC the most important input?
WACC determines how heavily future cash flows are discounted. A higher WACC means future FCF is worth less today, so a higher growth rate is needed to justify the same price. A 2% change in WACC can shift the implied growth rate by several percentage points — which is why the sensitivity table shows results at WACC ±1%.
Can I use this to find undervalued stocks?
Yes. If the implied growth rate is well below what the company has historically delivered, the market may be pricing in deceleration that doesn't materialize. This is a signal to investigate further — not a buy signal by itself. Pair with a full DCF, earnings quality check, and competitive analysis.
