What Is Reverse DCF?
A classic DCF asks 'what is the stock worth at this growth rate?'. Reverse DCF flips it: it takes the current market price as given and asks 'what annual free cash flow (FCF) growth, for how many years, would justify this price?'. In other words, it surfaces the growth expectation baked into the price.

How to read
- Implied growth = the annual FCF growth rate that equates today's price to present value.
- Compare it against the company's historical FCF growth and analyst estimates.
- Implied growth < realistic growth ⇒ price is conservative (potential discount).
- Implied growth > achievable growth ⇒ price is optimistic (fragility).
Threshold ranges
- <5%Low expectation — reasonable for mature firms, may be cheap on growth
- 5–10%Moderate expectation — achievable for most quality firms
- 10–15%High expectation — question sustainability
- >15%Aggressive expectation — hard to sustain for long
Watch out for
- WACC and terminal growth assumptions move the result a lot; think in a range rather than a single rate.
- Reverse DCF is unreliable for firms with negative or highly volatile FCF (early-stage, cyclical).
- A 'low' implied growth is not always cheap — the market may be pricing a lasting problem.
Sector note
High-margin businesses (software/platforms) naturally imply higher growth; compare against peers' implied growth instead of judging the absolute rate.
