One of the most common methods for assessing the value of a business or investment opportunity is the discounted cash flow (DCF) method. This approach involves calculating the present value of the future expected cash flows, taking into account the time value of money. In simpler terms, DCF is one of three main ways to determine an investment’s fair market value based on its projected future earnings.
Understanding discounted cash flow and time value of money
The principle behind DCF is that an investment is only worth as much cash as it generates. By discounting future cash flows to their present value, DCF accounts for both the timing and the risk associated with those cash flows. Since money received in the present is worth more than the same amount of money received in the future, DCF considers the time value of money in its calculations.
As an example, let’s say you are considering investing in a company that’s generating $100,000 in cash flow each year for the next five years. Due to inflation and other factors, receiving $100,000 in five years will not be as valuable as earning $100,000 today.
This is where discounted cash flow comes in. By calculating the present value of those future $100,000 years using an appropriate discount rate (determined by the company’s cost of capital), DCF paints a more accurate picture of what that $100,000 would actually get you in terms of investment ROI.
Benefits of using the DCF method
The main advantages of using the discounted cash flow method are that it:
- Recognizes that a dollar received today is worth more than a dollar received in the future.
- It takes into account the risk and uncertainty in future cash flow projections, especially as you zoom out.
- Allows for a more accurate comparison of different investment opportunities by converting.
- Can be used for both simple and complex investments, making it a versatile valuation method.
Limitations of the DCF method
While there are clear benefits to using discounted cash flow, there are also a few areas where it falls short:
- Over-reliance on future projections and assumptions, which can be unpredictable
- Limited consideration for external factors that could affect the investment’s cash flow
- Sensitivity to small changes in calculation inputs, such as discount rate or terminal growth rate
Using DCF to assess a stock’s value
While we commonly use the DCF formula to analyze the value of a business, you can also use it for individual stocks. In this case, the best way to calculate discounted cash flow is by using a DCF calculator like Alphaspread. The tool automatically determines the stock’s intrinsic value, then compares it to the current market price to determine whether it’s overvalued or undervalued. In general:
- If the DCF is higher than the current investment cost, the stock is undervalued and considered a good buy.
- If the DCF is lower, it’s overvalued and most likely not a wise investment choice.
Endnote
You should use DCF as a tool rather than a determining factor in whether to make an investment decision. In addition to DCF, thorough research and analysis are essential to assess the investment’s potential risks and rewards. Using the steps and considerations outlined above, you’ll understand discounted cash flow and how it works, making you a more informed investor.
