What Is Discounted Cash Flow

Discounted Cash Flow: What Is It?

The term “discounted cash flow” (DCF) refers to a method of valuation that calculates an investment’s value based on its anticipated future cash flows.

Using estimates of how much money an investment will make in the future, DCF analysis seeks to evaluate the value of an investment today.

It can aid those who are trying to decide whether to purchase securities or a firm. Business owners and managers can use discounted cash flow analysis to help them make decisions about operational and capital budgets.

The Function of Discounted Cash Flow

A dollar you have today is worth more than a dollar you receive tomorrow because it can be invested, according to the time value of money theory. As a result, a DCF analysis is helpful in any circumstance where someone is paying money now with the hope of obtaining more in the future.

For instance, $1 in a savings account will be worth $1.05 after a year if the interest rate is 5%. Similar to this, if you cannot move a $1 payment to your savings account to collect interest, its current worth is just 95 cents.

Using a discount rate, discounted cash flow analysis determines the present value of anticipated future cash flows. The idea of the present value of money can be used by investors to assess whether the future cash flows of a project or investment will be more valuable than the initial investment.

Consider the opportunity if the computed DCF value is more than the investment’s current cost. If the calculated value is less than the cost, the opportunity might not be the best. Or, it could be necessary to conduct additional research and analysis before proceeding.

An investor must estimate future cash flows and the eventual value of the investment, machinery, or other assets in order to perform a DCF analysis.

For the DCF model, the investor must also choose an appropriate discount rate, which will change based on the project or investment being considered. The discount rate used can be influenced by a number of variables, including the risk profile of the company or investor and the state of the capital markets.

Alternative models should be used in place of DCF if the investor is unable to predict future cash flows or the project is too complex.

Benefits and Drawbacks of DCF Benefits

Investors and businesses can determine the value of a proposed investment using discounted cash flow analysis.

It is analysis that can be used for a range of capital investments and projects when it is possible to predictably estimate future cash flows.

Its projections can be changed to provide varied outcomes for different what-if scenarios. Users can utilize this to take into account various projections that could be made.


The main drawback of discounted cash flow analysis is that it uses guesses rather than precise numbers. Therefore, the DCF result is also an estimation. This means that in order for DCF to be effective, both businesses and individual investors must accurately estimate a discount rate and cash flows.

The market demand, the state of the economy, technology, competition, and unforeseen dangers or opportunities are just a few of the variables that affect future cash flows. These cannot be precisely measured. Investors’ decision-making depends on their awareness of this inherent disadvantage.

Even if accurate estimations can be generated, DCF shouldn’t necessarily be used entirely. When evaluating an investment opportunity, businesses and investors should also take into account other, well-known factors. Other typical valuation techniques that might be employed include prior transactions and similar company analysis.

How Is the DCF Calculated?

Three fundamental steps are involved in computing the DCF. First, project the investment’s anticipated cash flows. The second step is to choose a discount rate, which is normally determined by the investment’s financing costs or the opportunity costs associated with substitute investments. Three, using a financial calculator, a spreadsheet, or a manual computation, discount the anticipated cash flows back to the present.

What Is a DCF Calculation Example?

You have a 10% discount rate and a three-year investment opportunity that would return $100 annually. The present value of this stream of future cash flows is what you want to figure out.

You deduct your 10% discount rate from the present value of each of these cash flows because money in the future is worth less than it is today. More specifically, the cash flow from the first year is worth $90.91 today, the cash flow from the second year is worth $82.64 today, and the cash flow from the third year is worth $75.13 today. These three cash flows are added up, and you come to the conclusion that the investment’s DCF is $248.68.

Is Net Present Value (NPV) the Same as Discounted Cash Flow?

Although the two ideas are closely similar, it’s not. A fourth stage is added to the DCF calculation procedure by NPV. The upfront investment cost is subtracted from the DCF by the NPV after projecting the expected cash flows, choosing a discount rate, discounted those cash flows, and adding them up. The NPV of the investment, for instance, would be $248.68 less $200, or $48.68, if the cost of purchasing the investment in our example above was $200.
