The Discounted Cash Flow Calculator helps investors, financial analysts, and business students determine the intrinsic value of an investment based on its expected future cash flows. By discounting future earnings back to their present value using a specified discount rate or WACC, this tool solves the core problem of asset valuation: figuring out what future money is actually worth today.

How Discounted Cash Flow Works

The DCF model relies on the principle that the value of any asset is the present value of all the cash it will generate in the future. The total valuation is split into two primary components: the explicit growth period value and the terminal value. First, the growth value sums the discounted cash flows (such as Earnings Per Share or Free Cash Flow) over a projected number of years using the formula: Growth Value = EPS * [((1 + g) / (1 + r)) * (1 - ((1 + g) / (1 + r))^n)] / [1 - ((1 + g) / (1 + r))], where 'g' is the growth rate, 'r' is the discount rate, and 'n' is the number of forecast years. Second, the terminal value captures all cash flows beyond the forecast period using a perpetual growth rate and terminal duration. Adding these two calculated values yields the total DCF valuation.

Worked Calculation Example

Imagine you want to evaluate a stock with an initial Earnings Per Share (EPS) of $4.00. You project a growth rate (g) of 5% per year for the next 5 years, and you apply a discount rate (WACC) of 9%. Furthermore, you estimate a terminal growth rate of 2% for a terminal duration of 10 years. Plugging these figures into the growth value formula, the present value of the explicit 5-year growth period totals approximately $18.45 per share. Next, using the terminal value formula, the discounted value of the subsequent terminal period calculates to roughly $28.30 per share. Summing both components together (Growth Value + Terminal Value), the final DCF intrinsic value is $46.75 per share, giving you a clear benchmark against its current market price.

Practical Tips for Accurate DCF Modeling

Always use conservative growth rates to avoid overvaluing the asset due to overly optimistic projections. Ensure that your discount rate (or WACC) accurately reflects the true risk profile and cost of capital for the specific industry or company you are analyzing. Finally, perform sensitivity analyses by tweaking your discount and terminal growth rates slightly to see how resilient your valuation target is.

FAQs

Can I use negative free cash flow in the discounted cash flow analysis?

Using negative free cash flow is technically possible for early-stage or distressed companies, but it complicates the model significantly. Standard multi-year exponential growth formulas break down or yield counterintuitive results when applied to negative baselines. Analysts usually wait until the company reaches a predictable inflection point toward profitability, or they project cash flows manually year-by-year until positive cash flow is established before applying a standard DCF formula.

How to discount cash flows to the firm?

Discounting cash flows to the firm (FCFF) involves forecasting the cash available to all capital providers—both debt and equity holders—after operating expenses and investments. You then discount these cash flows using the Weighted Average Cost of Capital (WACC) as the discount rate. This yields the total enterprise value of the company, from which you subtract net debt to arrive at the equity value.

Which is a good value for the perpetual growth rate in the discounted cash flow model?

A realistic perpetual growth rate should generally align with the long-term nominal GDP growth rate of the economy in which the company operates, typically falling between 2% and 4% for mature, developed markets. Setting a perpetual growth rate higher than the broader economic growth rate implies the company will eventually grow larger than the entire economy, which is theoretically impossible over the long run.

Can WACC be equal to the perpetual growth rate in the discounted cash flow method?

The WACC can never equal or fall below the perpetual growth rate within standard Gordon Growth or terminal value formulas. If the discount rate equals the perpetual growth rate, the denominator in the perpetuity equation becomes zero, resulting in a mathematical division by zero error and producing an infinitely large or undefined terminal value.
