Discounted Cash Flow

A valuation method that estimates the present value of an asset based on its projected future cash flows, discounted at a rate reflecting the riskiness of those cash flows. DCF is the foundation of fundamental valuation in finance: an asset is worth the sum of what it will produce, adjusted for time and risk. Unlike relative valuation (comparing to peers), DCF derives value from first principles—what the asset itself will generate. Every M&A deal, capital budgeting decision, and fundamental stock analysis ultimately rests on DCF logic.

When to use it

When valuing any asset, business, or investment; when building business plans that need to show financial viability; when evaluating M&A targets or making capital allocation decisions; when the question is 'what is this actually worth?' rather than 'what will someone pay for it?'

How it can help

Build the habit of asking: 'What cash flows will this generate, and what are they worth today?' This applies beyond finance: a hire's 'DCF' is their expected contribution minus their cost over their tenure. A product's 'DCF' is its expected revenue stream minus ongoing costs. The framework forces you to think in concrete terms about future value rather than vague notions of 'worth.' The most important inputs to get right: terminal growth rate, discount rate, and near-term cash flow assumptions.
