Valuation

What is Discounted Cash Flow (DCF)?

Definition

Discounted Cash Flow is a valuation method that estimates the present value of an investment based on its expected future cash flows. It is considered one of the most rigorous approaches to determining a company's intrinsic value.

Detailed Explanation

A DCF model projects a company's future free cash flows over a forecast period (typically 5-10 years) and then discounts them back to present value using the weighted average cost of capital (WACC). A terminal value is added to capture value beyond the forecast period, often representing 60-80% of the total DCF value.

The core principle is the time value of money: a dollar received today is worth more than a dollar received in the future because today's dollar can be invested to earn a return. The discount rate reflects the riskiness of the cash flows—higher risk requires a higher discount rate.

DCF analysis is sensitive to its assumptions. Small changes in the growth rate, discount rate, or terminal value can significantly change the result. This is why analysts typically run sensitivity analyses showing how the valuation changes under different scenarios.

Despite its complexity, DCF is favored by professional investors because it forces disciplined thinking about a company's fundamentals—revenue growth, margins, capital requirements, and risk—rather than relying on market multiples alone.

Formula

DCF = Sum of [FCF_t / (1 + WACC)^t] + Terminal Value / (1 + WACC)^n

Example

An analyst projects a company will generate $500M in FCF next year, growing at 8% annually for 5 years, with a terminal growth rate of 3% and a WACC of 10%. The DCF model yields an intrinsic value of $7.2 billion, or $72 per share on 100M shares.

Frequently Asked Questions

How accurate are DCF valuations?

DCF models are only as good as their assumptions. They are best used as a framework for thinking about value rather than a precise calculator. Running sensitivity analyses across different scenarios provides a valuation range rather than a single number.

What discount rate should I use?

Most analysts use the Weighted Average Cost of Capital (WACC), which blends the cost of equity and cost of debt. For the S&P 500, WACC typically ranges from 8-12%. Higher-risk companies warrant higher discount rates.

When is DCF analysis most useful?

DCF works best for companies with predictable, positive cash flows. It is less useful for early-stage companies with no cash flow, highly cyclical businesses, or financial companies where cash flow definitions differ.

Related Terms

Free Cash Flow

Free cash flow (FCF) is the cash a company generates from its operations after accounting for capital expenditures needed to maintain or expand its asset base. It represents the cash available for dividends, debt repayment, buybacks, and acquisitions.

Intrinsic Value

Intrinsic value is the estimated true worth of a company or asset based on fundamental analysis, independent of its current market price. When the market price is below intrinsic value, value investors consider the stock undervalued and a potential buying opportunity.

Terminal Value

Terminal value represents the estimated value of a business beyond the explicit forecast period in a DCF model. It captures all future cash flows after the projection period and typically accounts for 60-80% of the total DCF valuation.

Weighted Average Cost of Capital (WACC)

WACC is the average rate of return a company must earn on its existing assets to satisfy all capital providers—both equity holders and debt holders. It is used as the discount rate in DCF valuations and reflects the blended cost of all financing sources.
