what is a discounted cash flow?

Written By Rohil Patel

Hey teenagetraders! If you’re diving into the world of investing and finance, understanding Discounted Cash Flow (DCF) is crucial. It’s a key valuation method used to assess the value of an investment based on its expected future cash flows. Let’s break it down step by step so we can understand it.

1. What is Discounted Cash Flow (DCF)?

Discounted Cash Flow (DCF) is a financial valuation method used to estimate the value of an investment, or a company based on the present value of its expected future cash flows. The core idea is that money today is worth more than the same amount of money in the future due to its potential earning capacity. DCF takes this principle into account to determine the value of an investment today.

2. How Does DCF Work?

1. Estimate Future Cash Flows

  • Description: The first step in a DCF analysis is to project the future cash flows that an investment or company is expected to generate. These can include revenues, operating profits, and net income.

  • Example: For a company, you might estimate future cash flows based on its historical performance and growth expectations. If you expect a company to generate $1 million in cash flow next year, $1.1 million the following year, and so on, these are your projected cash flows.

2. Determine the Discount Rate

  • Description: The discount rate is used to calculate the present value of future cash flows. It reflects the riskiness of the cash flows and the time value of money. Commonly, the Weighted Average Cost of Capital (WACC) is used as the discount rate for companies.

  • Example: If you determine that the discount rate is 8%, you’ll use this rate to discount future cash flows back to their present value.

3. Calculate the Present Value of Future Cash Flows

  • Description: Using the discount rate, you discount each of the future cash flows to determine their present value. This involves applying a formula to each year’s projected cash flow.

  • Example: If the future cash flow in one year is $1 million and the discount rate is 8%, the present value of that cash flow is calculated as $1 million / (1 + 0.08) = $925,926.

4. Sum the Present Values

  • Description: Add up all the present values of the future cash flows to get the total present value of the investment or company.

  • Example: If you have discounted cash flows for five years, you sum the present values of each year to find the total present value of the investment.

5. Consider Terminal Value

  • Description: For long-term investments, it’s common to calculate a terminal value, which represents the value of all future cash flows beyond a certain point, using a perpetuity formula or an exit multiple.

  • Example: If you expect the company to continue generating cash flows indefinitely, you calculate a terminal value and discount it back to the present value.

3. Formula for DCF

The basic formula for calculating the present value of future cash flows is:

DCF=CF1/(1+r)1+CF2/(1+r)2+CF3/(1+r)3+…

Where:

  • CF = Cash Flow in each period

  • r = Discount Rate

  • n = Number of periods

4. Example of a DCF Calculation

Let’s say you’re evaluating a company and expect the following cash flows for the next three years:

  • Year 1 Cash Flow: $100,000

  • Year 2 Cash Flow: $120,000

  • Year 3 Cash Flow: $140,000

You use a discount rate of 10%. Here’s how you calculate the present value:

  • Year 1: 100,000/(1+0.10)1=90,909

  • Year 2: 120,000/(1+0.10)2=96,694

  • Year 3: 140,000/(1+0.10)3=105,096

Adding these present values gives you a total present value of $292,699.

5. Pros and Cons of DCF

Pros

  • Intrinsic Value: Provides a detailed estimate of an investment’s intrinsic value based on expected cash flows.

  • Flexibility: Can be adapted to various types of investments and business models.

Cons

  • Complexity: Requires accurate cash flow projections and a suitable discount rate, which can be challenging to determine.

  • Sensitivity: Results can be highly sensitive to assumptions about future cash flows and discount rates.

Final Thoughts

Discounted Cash Flow (DCF) is a powerful valuation tool that helps you assess the value of an investment based on its projected cash flows. By understanding and applying DCF, you can make more informed investment decisions and better evaluate potential opportunities. Remember, while DCF provides valuable insights, it’s important to consider other factors and methods in your analysis.
