What Is DCF Valuation? A Beginner Guide

Discounted Cash Flow (DCF) is the gold standard method for estimating what a stock is truly worth.

How DCF Works

The core idea is simple: a company is worth the sum of all future cash flows it will generate, discounted back to today's value.

The Three Key Inputs

Projected Free Cash Flows — Estimate how much cash the company will produce each year over a forecast period (typically 5–10 years).
Discount Rate — The rate used to convert future cash flows into present value. Usually the Weighted Average Cost of Capital (WACC), reflecting the risk of the investment.
Terminal Value — An estimate of the company's value beyond the forecast period, since businesses don't stop generating cash after year 10.

The Formula

The intrinsic value is calculated as:

Intrinsic Value = Σ (FCFₜ / (1 + r)ᵗ) + Terminal Value / (1 + r)ⁿ

Where FCFₜ is the free cash flow in year t, r is the discount rate, and n is the number of forecast years.

Why Investors Use DCF

Fundamental approach — It focuses on what a business actually produces, not market sentiment.
Flexible — Works for any cash-generating business across industries.
Forward-looking — Captures growth expectations rather than relying on historical multiples alone.

Limitations to Keep in Mind

No valuation method is perfect. DCF is sensitive to assumptions — small changes in growth rate or discount rate can significantly alter the result. That's why experienced analysts often run multiple scenarios (bull, base, bear) and compare DCF results with other methods like comparable company analysis.
