DCF model Excel - the 3 inputs most analysts quietly get wrong

About this tutorial

DCF model Excel builds are one of the most powerful ways to estimate a stock's intrinsic value, yet most investors copy a template without understanding which three inputs quietly destroy the output. This live session shows you how to build a clean, functional DCF model inside Excel using MarketXLS real-time data, so every assumption is grounded in live numbers rather than stale copy-paste figures. What you'll see in this session: - Pulling live revenue, operating income, and free cash flow history for any ticker using MarketXLS functions like =mxs_quote() and income-statement historicals, so your base-year figures are always current - Building a 5-year revenue growth projection tied directly to analyst consensus growth rates fetched in real time, rather than manually typed guesses - Calculating unlevered free cash flow row by row in Excel, with each formula labeled so you can audit and adjust every assumption on screen - Estimating a weighted average cost of capital (WACC) using live beta, current risk-free rate pulled from a Treasury feed, and market cap data sourced automatically from MarketXLS - Computing a terminal value using both the Gordon Growth Method and an exit-multiple approach side by side, so you can see how sensitive your final valuation is to that single assumption - Discounting all cash flows back to present value and surfacing a per-share intrinsic value that updates automatically when the underlying MarketXLS data refreshes Why this matters: a DCF model is only as trustworthy as the data feeding it. When analysts hard-code revenue figures or use a WACC they estimated six months ago, the intrinsic value they calculate is already stale before they finish the model. By connecting every input cell to a live MarketXLS data pull, the spreadsheet becomes a living valuation tool rather than a one-time exercise. That means when a company reports earnings, revises guidance, or when interest rates shift, your intrinsic value estimate adjusts in real time without you rebuilding the model from scratch. For long-term investors deciding whether a stock is genuinely undervalued or just optically cheap on a trailing P/E basis, having a DCF model that breathes with the market is the difference between a defensible buy decision and a hopeful one. This session is especially useful for individual investors, finance students, and analysts who want a repeatable, auditable valuation framework they can apply to any publicly traded company in minutes. The entire model is built live in Excel with MarketXLS real-time data during this broadcast. A link to the MarketXLS demo and template will be in the comments so you can follow along or rebuild it yourself after the session ends.
