Discounted Cash Flow (DCF): How to Value a Stock's True Worth

Formula

Sum of (Future Cash Flow / (1 + Discount Rate)^n)

What is Discounted Cash Flow?

Discounted Cash Flow analysis estimates what a company is worth today based on how much cash it’s expected to generate in the future. The core idea: a dollar earned next year is worth less than a dollar today, so future cash flows are “discounted” back to present value.

If the DCF value is higher than the current stock price, the stock may be undervalued. If it’s lower, you might be overpaying.

Why it matters for investors

DCF is one of the few valuation methods that tries to calculate an absolute fair value — not a relative comparison to other stocks. Warren Buffett famously uses DCF-style thinking when evaluating investments.

It answers the question every investor should ask: “Based on this company’s expected earnings, what should the stock actually be worth?”

How Stock Analyzer scores it

Stock Analyzer compares the DCF value to the current stock price as a percentage:

ScoreDCF vs. PriceWhat it means
ADCF is 110%+ of priceStock appears undervalued
B100% – 110%Close to fair value
C95% – 100%Slightly overvalued
D85% – 95%Overvalued
EBelow 85%Significantly overvalued

What to watch out for

DCF models are only as good as their assumptions. Small changes in growth rate or discount rate can dramatically change the result. Use DCF alongside other metrics — it’s most useful when it agrees with other valuation signals.
