DCF (Discounted Cash Flow) — A Quick Definition
DCF (Discounted Cash Flow) is a pricing model that values a stock as the sum of all the company's future free cash flows, discounted back to today's value.
The basic idea: a dollar received five years from now is worth less than a dollar today, so future cash flows have to be 'discounted' (reduced) at a certain rate before being added up. Summing all the discounted flows, subtracting net debt, and dividing by the share count gives an estimated fair value per share.
The critical variable in the model is the discount rate (usually derived from WACC — weighted average cost of capital): a change of a single percentage point in this rate can shift the result by tens of percent, which is why DCF results from different sources can look very different — all 'correct' mathematically, but built on different assumptions.
How StockIQ AI uses this
DCF is the central model in StockIQ's fair value category (15% of the score), computed alongside a net asset value (NAV) comparison and a P/E multiple comparison — so no single pricing model is relied on alone.
Frequently asked questions
How accurate is a DCF valuation?
Not very — it's highly sensitive to assumptions about future growth and the discount rate, both of which are forecasts, not facts. DCF is useful for estimating an order of magnitude (whether a stock is roughly cheap, expensive, or fairly priced relative to what the company actually generates), not as a tool that produces a precise 'price target'.
What is the discount rate in a DCF model?
The discount rate (usually derived from WACC) is the rate used to reduce future cash flows to today's value, reflecting both the time value of money and the company's risk level. The riskier a company is considered, the higher the discount rate — and the lower the resulting valuation.
