![]() ![]() Then, the 1st year cash flow of $100 is divided by 1.10 to get $91 for the PV of the cash flow. From doing so, the output is 1.10.Ĭonversely, the factor increases over time in the 2nd approach since the cash flows are being divided by this >1 factor. Recall how this time around, the cash flow will be divided by the discount factor to get the present value.Īnd in contrast to the 1st approach, the factor will be in excess of 1.įor 2021, the discount rate of 10% is added to 1, which is raised to the exponent of 1, as that is the first projected year. The 0.91 is subsequently multiplied by the cash flow of $100 to get $91 as the PV of the 1st year cash flow.īy the end of Year 5, we can see the discount factor drop in value from 0.91 to 0.62 by the end of the forecast period due to the time value of money. In the hypothetical scenario we will be using, the company has the following financial profile:įor example, in 2021, the discount factor comes out to 0.91 after adding the 10% discount rate to 1 and then raising the amount to the exponent of -1, which is the matching time period. The formula for the second approach is virtually identical, except for the absence of the negative sign in front of the period number exponent. The example implies that $1 dollar received one year from the current period would be worth $0.91 in the present day. Next, the present value can be calculated using: To tie this back to the example using $1, assuming a 10% discount rate and a one-year time horizon – the discount factor would be calculated as: This also ties back to what we discussed at the beginning, where receiving $1 today is more valuable than receiving $1 in the future. Intuitively, the discount factor, which is always calculated by one divided by a figure, decreases the cash flow values. Note that the period can be whatever length you want (years, months, days, even hours) – but it is critical to ensure that the period is aligned with the implied period of the discount rate. While the discount rate remains constant throughout the projection, the period number rising is what causes the factor to decrease over time. ![]() Present Value (PV) = Cash Flow x Discount Factor The first formula for the discount factor has been shown below. The reason you would prefer to have $1 today than $1 three years from now is that if you received the $1 three years from now, you would have missed out on a full three years when you could have invested that $1 and ended up with more than $1 by the end of that time. The discount rate can be thought of as representing the percentage of return that you could have received by investing that dollar, if you had received it today. Generally speaking, there are two approaches to calculating the discount factor, but in either case, the discount factor is a function of the: the value of future cash in today’s dollars) is calculated by multiplying the cash flow for each projected year by the discount factor, which is driven by the discount rate and the matching time period. The Discount Factor is used to calculate what the value of receiving $1 at some point in the future would be (the present value, or “PV”) based on the implied date of receipt and the discount rate assumption. ![]()
