A reverse DCF solves for the growth rate the current price is baking in.
What it is
A reverse discounted-cash-flow (DCF) flips a normal DCF around. Instead of forecasting cash flows and a discount rate to compute a fair value, you plug in the current market price plus a discount rate and terminal assumptions, then solve for the future free-cash-flow growth rate (and sometimes the margin) that makes the model output equal that price. The result is the "expectations baked into the stock" — the growth the market is implicitly pricing in. You then judge whether that implied growth is realistic for the business.
Why it matters
It reframes valuation from "what is this worth?" to "what does the price already assume?", which is often a more answerable question and sidesteps the false precision of forecasting cash flows you cannot know. The pitfall: the implied growth rate is extremely sensitive to the discount rate and terminal-growth assumption — nudging terminal growth from 2% to 3%, or WACC by a point, can swing the answer dramatically. Treat it as a sanity check on whether expectations look reasonable, never as a precise number; a single tweaked input can flip a stock from "cheap" to "priced for perfection."
How it's calculated
Build a standard DCF skeleton — an explicit forecast horizon (usually 5–10 years) plus a terminal value — and fix the discount rate (WACC or cost of equity) and the terminal-growth assumption. Then, holding the model's present value equal to the current market price (or enterprise value), iteratively solve for the explicit-period growth rate that closes the gap. That solved growth rate is the market-implied expectation you compare against the company's realistic prospects.
How Quintarthai uses it
Use a company's deep-analysis page at /app/ to read the reported free cash flow, growth history, and discount-rate inputs you need to frame a reverse DCF, then sanity-check the implied growth against peers in the stock screener. See the Knowledge Base entries on discounted cash flow and terminal value to set defensible assumptions first.
Cross-border note. The mechanics are identical for Canadian (TSX) and US-listed companies, but the discount rate and terminal-growth inputs differ by market: use the cash flow's own currency (CAD for a TSX filer, USD for a US filer) and a country-appropriate risk-free rate, and never mix a USD cost of capital with CAD cash flows. For Canadian companies reporting under IFRS, confirm the free-cash-flow definition matches what you would use for a US GAAP filer before comparing implied growth across the border.
FAQ
How do I decide whether the implied growth rate is too high?
Compare it to the company's own historical revenue and free-cash-flow growth, its peers, and the size of its addressable market. If the price requires growth well above what the business has ever sustained — or above what the whole industry is growing — expectations are likely stretched.
Why does my reverse DCF give a wildly different answer when I change one input?
Because terminal value usually makes up most of the total value, small changes to the discount rate or terminal-growth rate produce outsized swings in implied growth. Always run a range of assumptions rather than trusting a single point estimate.
Check your understanding
A stock trades at a price where a reverse DCF implies 18% annual free-cash-flow growth for the next decade, but the company has averaged 6% growth historically and operates in an industry growing about 5% a year. What is the most reasonable conclusion?
A reverse DCF reveals the expectations baked into the price; an 18% implied rate that dwarfs the company's 6% history and a 5% industry signals optimistic, possibly unrealistic, assumptions. It is a sanity check, not a proof of fair value.
