The Rich-Data DCF

Remember the basics. New to discounted cash flow, or need the definition again? Start here → What a DCF is. This section assumes you already know the mechanics.

You already know a DCF discounts future cash flows to today. That is the part AI now does in seconds. The part that decides whether your valuation survives a partner's scrutiny is the quality of what goes into it. So we do not ask "what is a DCF." We ask the question a good analyst actually wrestles with:

What makes a DCF rich enough to trust?

The decisions that carry the weight

Three judgments hold most of a DCF's credibility.

• Projection versus horizon. How far out can you honestly forecast this specific company before the numbers become a guess? Where does explicit projection stop and terminal value take over, and how much of your valuation is hiding inside that terminal assumption?
• Which scenarios deserve weight. A single base case is a wish. Which two or three scenarios genuinely describe how this company could unfold, and why those and not others?
• How conservative to be, and where. A higher discount rate, a lower growth rate, and explicit cash-flow variability are not pessimism. They are how you price the uncertainty you cannot remove.

How to structure it

Build so the reader sees the logic, not just the answer. Keep assumptions on one clearly labelled sheet, drivers separated from outputs, and every sensitivity visible rather than buried. A partner should be able to trace any number back to the assumption that produced it in a single step.

What excellent looks like

A weak DCF gives one number. An excellent DCF gives a defended range and tells you where it is fragile. You can point to the two assumptions that move the valuation most, show how the value shifts across your scenarios, and explain why the terminal value is, or is not, doing too much of the work.

Where the Skill multiplies you

On your own, testing many growth and discount combinations by hand is slow, so most analysts test few and the model stays thin. The DCF Skill, built on Claude for Financial Services, changes the ceiling: pressure-test dozens of sensitivity cases, decompose the projection horizon, and surface where your value is most fragile, in the time it once took to build a single case. The judgment stays yours. The reach becomes far greater.

Adapting the Skill

No two companies carry the same risks, so the Skill is a starting point, not a stamp. Adjust its scenario set, its discount logic, and its variability assumptions for the specific firm in front of you. A tool you reshaped for the job is the one you can defend.
