What is Discounted Cash Flow and How to Calculate It

The Discounted Cash Flow (DCF) method stands as a crucial financial analysis approach employed to assess the worth of an investment or a business by considering its anticipated future cash flows.

It is an essential tool for investors, business owners, and financial analysts to assess the attractiveness of an investment opportunity. DCF incorporates the concept of the time value of money, acknowledging that the value of money at present surpasses the value of the same amount in the future, taking into account variables such as inflation and potential risks.

Understanding Discounted Cash Flow

To grasp the concept of Discounted Cash Flow, it is crucial to comprehend the core elements involved:

Cash Flow Projections

DCF begins with estimating the future cash flows generated by the investment or business. These cash flows could include revenues, operating expenses, taxes, and capital expenditures over a specified period. The more accurate the projections, the more reliable the DCF analysis will be.

Time Value of Money

The time factor plays a significant role in the growth of money through diverse investment opportunities. Consequently, the value of a dollar received in the future is diminished compared to receiving that same dollar today. DCF addresses this principle by discounting future cash flows to their present value.

Discount Rate

The discount rate, also known as the required rate of return or cost of capital, is a crucial factor in DCF calculations. It represents the return an investor expects to earn on their investment considering the risk associated with it. The higher the risk, the higher the discount rate and vice versa.

Calculating Discounted Cash Flow

To calculate the Discounted Cash Flow, follow these steps:

Step 1: Cash Flow Projections

To initiate the DCF analysis, start by conducting a comprehensive estimation of the cash flows anticipated from the investment or business within a specified timeframe, typically ranging from 5 to 10 years. These projections should be founded on a thorough examination of historical data, industry trends, and foreseeable market conditions.

Step 2: Determine the Discount Rate

Assign an appropriate discount rate to the investment, reflecting its risk profile. For example, a safe and stable investment might have a discount rate of 8%, while a riskier venture could have a discount rate of 12% or higher.

Step 3: Discount the Cash Flows

Using the discount rate, discount each projected cash flow back to its present value. This can be achieved using the following formula:

DCF = CF1 / (1 + r)^1 + CF2 / (1 + r)^2 + ... + CFn / (1 + r)^n


DCF = Discounted Cash Flow

CF1, CF2, ..., CFn = Cash flows in different periods (e.g., year 1, year 2, ..., year n)

r = Discount rate

Step 4: Calculate Terminal Value

After the projected period, estimate the terminal value, representing the value of the investment beyond the projection period. This is usually done by applying a multiple (such as a Price/Earnings ratio) to the last projected year's cash flow.

Step 5: Sum the Present Values

Add the discounted cash flows from Step 3 and the terminal value from Step 4 to get the total present value of the investment or business.

Importance of Discounted Cash Flow

DCF offers several key benefits and plays a vital role in financial decision-making:

  • Investment Valuation: DCF provides a robust and objective approach to assess the worth of an investment, enabling investors to compare different opportunities and make informed choices.

  • Informed Capital Budgeting: Businesses use DCF to analyze potential projects and determine which ones will generate the highest return on investment.

  • Mergers and Acquisitions: DCF is frequently employed in merger and acquisition negotiations to ascertain a fair price for the target company.

Let's consider an example to illustrate the calculation of Discounted Cash Flow. Suppose Company XYZ is considering investing in a new project that is expected to generate the following annual cash flows over the next 5 years:

  • Year 1: $100,000
  • Year 2: $120,000
  • Year 3: $150,000
  • Year 4: $180,000
  • Year 5: $200,000

Assuming a discount rate of 10%, we can now calculate the DCF:

DCF = $100,000 / (1 + 0.10)^1 + $120,000 / (1 + 0.10)^2 + $150,000 / (1 + 0.10)^3 + $180,000 / (1 + 0.10)^4 + $200,000 / (1 + 0.10)^5

DCF โ‰ˆ $100,000 / 1.10 + $120,000 / 1.21 + $150,000 / 1.33 + $180,000 / 1.46 + $200,000 / 1.61

DCF โ‰ˆ $90,909 + $99,174 + $112,782 + $123,288 + $124,224 โ‰ˆ $550,377


Discounted Cash Flow is a powerful financial tool used to evaluate investments and businesses objectively. By considering future cash flows and the time value of money, DCF allows investors and business owners to make informed decisions based on sound financial analysis. Understanding and applying DCF can lead to better investment choices, prudent capital budgeting, and accurate valuation of assets, ultimately contributing to long-term financial success.
