I try to understand about DCF. reading this article https://www.investopedia.com/terms/d/dcf.asp in Alternative Investments part, can't figure out what's the calculation is used to get to $289,157.47 current value
copying from the site above:
Alternative Investments An investor could set their DCF discount rate equal to the return they expect from an alternative investment of similar risk. For example, Aaliyah could invest $500,000 in a new home that she expects to be able to sell in 10 years for $750,000. Alternatively, she could invest her $500,000 in a real estate investment trust (REIT) that is expected to return 10% per year for the next 10 years.
To simplify the example, we will assume Aaliyah is not accounting for the substitution costs of rent or tax effects between the two investments. All she needs for her DCF analysis is the discount rate (10%) and the future cash flow ($750,000) from the future sale of her home. This DCF analysis only has one cash flow so the calculation will be easy.
In this example, Aaliyah should not invest in the house because her DCF analysis shows that its future cash flows are only worth $289,157.47 today. Once tax effects, rent, and other factors are included, Aaliyah may find that the DCF is a little closer to the current value of the home. Although this example is oversimplified it should help illustrate some of the issues of DCF including finding appropriate discount rates and making reliable future predictions.
