DCF: What Is a Company Really Worth?

DCF estimates what a company is worth based on its future cash flows, discounted back to today. It is the most fundamental valuation method in finance.

Live data

AAPL — Current Price, P/E Ratio. Open AAPL on the Ledge to see current values.

Step through

Step 1: Forecast free cash flows for the next 5-10 years based on revenue growth, margins, and capital needs.

Step 2: Estimate terminal value -- what the business is worth after your forecast period (usually using a growth rate of 2-3%).

Step 3: Discount everything back to present value using WACC (the company's cost of capital). A dollar next year is worth less than a dollar today.

Step 4: Calculate margin of safety -- how far below your estimate the stock trades. This platform uses (intrinsic value - price) / intrinsic value. Some use price as denominator instead.

Formula

Margin of Safety = (Intrinsic Value - Price) / Intrinsic Value

Try it

Open any ticker and look at the **Valuation** section. Check the DCF estimate and compare to the current price.

Key insight

DCF is powerful but fragile. Small changes in growth rate or discount rate can swing the result by 50%. That is why margin of safety exists: it is your buffer against being wrong.

Check-in

Your DCF model says intrinsic value is $150/share. The stock trades at $100 — a 50% upside. How confident should you be?
