A DCF is machinery for one sentence: value is the present value of expected cash flows
Aswath Damodaran · Session 3: Intrinsic and DCF Valuation — Laying the Groundwork
The idea
Damodaran opens his valuation course by defining intrinsic value in a sentence: the value of any asset is the present value of the cash flows you expect it to generate, discounted at a rate that reflects their risk. Everything else in a discounted cash flow model, the forecast, the terminal value, the discount rate, is machinery for that sentence. Keeping the sentence in view is what stops a model becoming a spreadsheet exercise: every input is either a claim about future cash or a claim about its risk, and an interviewer's follow-up questions are all variations on which one you got wrong.
Every cell in a DCF is a claim about future cash or about its risk; if you cannot say which, the cell should not be there.
When it works
The first DCF question in any interview, and whenever a model has grown so large that nobody can say what it is for.
When it may fail
Expected cash flows are forecasts and the discount rate is an estimate, so the sentence is exact and the answer is not. The method's honesty is that it shows where the uncertainty sits.
How to use it
Before opening the model, write the sentence and then list the three inputs that move the answer most. The Reverse DCF lab shows the sentence run backwards: what cash flows the price already assumes.

What the source says. Damodaran defines intrinsic valuation as the present value of expected cash flows, discounted at a rate reflecting their risk, and sets the rest of the course up as the machinery for that definition.

Takes it further
Every forecast row is a sentence about the businessA forecast is a story written in numbers; if a row cannot be said as a sentence about the business, it should not be in the model.
Takes it further
Terminal value is usually most of the answer, and most of the riskCheck what share of the value is terminal and what multiple the terminal assumptions imply; those two checks catch most broken DCFs.
Says something similar
Price is what the market offers you today. Value is the separate questionDecide what a business is worth before looking at the price, then act only when the price is far enough below.
Takes it further
A capital-structure-neutral cash flow needs a capital-structure-neutral discount rateMatch the discount rate to the cash flow: a flow to all capital providers is discounted at the blended cost of all of them.
Puts it to work
Earnings growth is return on capital times reinvestment, which is the AI spending questionSpending is only growth if the return on it exceeds the cost; estimate the return under several assumptions before admiring the spend.
