Discounted Cash Flow Valuation Explained
Discounted cash flow, or DCF, estimates value by converting expected future cash flows into present amounts at a rate consistent with their risk and ownership claim. It is a conditional model, not an observable fact.
How it works
Use cash flow to equity with an equity discount rate or cash flow to the firm with a consistent weighted financing rate. Do not mix them. Present value of a single flow is CF/(1+r)^t. A terminal value requires an explicit long-run assumption and can dominate the result.
Worked example
Suppose an equity claim will distribute 10 in one year and 110 in two years, including all final proceeds. At 10%, value is 10/1.10+110/1.10²=100. At 15%, value is about 91.87. This example assumes the cash flows occur exactly as stated; changing operating forecasts changes value independently of the discount rate.
Amounts, prices and scenarios are fictional teaching examples. They exclude any effects not explicitly stated and are not trade recommendations.
Limits and common mistakes
Small rate or terminal-growth changes can produce large differences. Growth often requires reinvestment, and high accounting earnings need not become distributable cash. Use scenarios and check that a perpetual-growth rate is below the discount rate.
Knowledge check
Does discounting make an uncertain forecast certain?
Read the explanation
No. It expresses assumptions consistently in present-value terms. Forecast errors and an inappropriate risk estimate can still make the result misleading.
