Valuation Methods
DCF Method: Bringing future cash flows to present value
The DCF method is a family of business valuation approaches. What they share is the discounting of future financial surpluses to the valuation date.
What the DCF method is
DCF stands for Discounted Cash Flow. It is not one single method, but a family of approaches that discount future cash flows to present value. In practice, the Adjusted Present Value (APV), the Weighted Average Cost of Capital (WACC), and the Equity approach are especially relevant.
Theoretical foundations
DCF approaches are closely linked to the equilibrium model of Modigliani and Miller and to the Capital Asset Pricing Model (CAPM). These models provide a basis for the discount logic, but they rely on restrictive assumptions that are only imperfectly met in real-world decision settings.
Main variants
APV approach: separates base present value, debt, and tax shield.
WACC approach: discounts the equity-financed cash flow using weighted average capital costs.
Equity approach: directly discounts the cash flow relevant to the owners using the cost of equity.
In theory, these approaches can be transformed into one another if assumptions remain fully consistent.
Why DCF is highly assumption-sensitive
Small changes in cash flows, growth rates, leverage, or discount rates can materially change the resulting company value. In many cases, the terminal value at the planning horizon also has a large impact on the overall result.
Possible misconceptions
"DCF automatically gives the one objectively correct business value."
No. DCF produces a model-dependent value under chosen assumptions. The result is only as robust as the quality of those assumptions.
"The discount rate is only a technical detail."
Wrong. The discount rate is one of the most important value drivers. Its derivation strongly affects the valuation result.
"DCF and decision value are the same thing."
Not necessarily. DCF approaches are typically based on capital-market-theoretical assumptions. The resulting value therefore does not automatically coincide with the decision value of a concrete valuation subject.
Scientific positioning in practice
DCF is useful as a structured cash-flow-based valuation framework and widely used in practice. From the perspective of functional valuation theory, however, one must critically ask whether the resulting value really represents the individual decision value of the actual party, or rather a capital-market-theoretical comparison or argumentation value.
Questions for orientation on the DCF method
What do APV, WACC, and Equity approach mean?
APV separates company value into base present value, debt value, and tax shield. WACC discounts using weighted average capital costs. The Equity approach discounts owner-relevant cash flows directly.
Is DCF better than the capitalised earnings method?
Not universally. Both are closely related in economic logic, but they differ in theoretical derivation, model design, and practical suitability depending on the assignment.
Why is the terminal value so important?
Because in many cases a large portion of total value is attributed to the continuation phase. Weak assumptions at this stage can distort the entire valuation.
Do you want to position or review a DCF valuation professionally?
I can support you with the transparent derivation of cash flows, discount logic, and assumptions, as well as with the critical review of existing models.
