The formula enables analysts to view the impact of compounding more clearly for each period. The discount factor formula is important, as it makes it easier to verify the DCF analysis and obtain more clarity in the net present value (NPV) when conducting financial modeling in excel. Using a discount factor enables the analyst to specify the number of days in each period.ĭiscounting cash flows enables the investor to assess the opportunity cost of undertaking the investment and take into account the time value of money, financing structure, and the risks involved in investing in a particular company vis-à-visor relative to the market. The discount rate is the rate of return that a project needs to earn to be acceptable to the investor. The choice of the discount rate (%) greatly affects the discount factor value.
We can also do this by using the NPA formula in excel.Ī key point to remember is that to arrive at or obtain the present value of the individual cash flow of any particular period (or year), we multiply the undiscounted cash flow of that period by the discount factor of that period. Thereafter, we derive the total net present value (NPV) of the cash flows – which can be calculated by adding up the individual discounted cash flows for each period (i.e. Once we obtain the discount factor for each period, we can multiply the same with the undiscounted cash flow for each period to obtain the discounted cash flow for each period. If we are given the discount rate (%) then we can use the aforesaid formula in an Excel spreadsheet to calculate the discount factor for each period (for example, years 1 to 10). The formula to calculate it is stated below: The discount factor is used by analysts when carrying out financial modeling in Excel. The decimal value of the discount factor gets smaller, as we go along from year 1 to 10 due to the effect of compounding that builds over time.The discount factor is computed through a formula that includes the discount rate (%) and the year or period number (for example year 1 to 10).A discount factor is a weighting factor that helps convert future values into the present.The advantage of using the discount factor is that it makes financial modeling more accurate. In financial modeling, once we obtain the undiscounted cash flows for the projected years or the years to come, we need to calculate their present value to evaluate whether the investment is profitable or not and how much is that company worth. The discount factor is also used by investors in the short-term money market, pension, and insurance companies, and to obtain future investment values. It is also used to calculate the net present value (NPV) which can be used to determine the net future value of an investment. The discount factor is used most commonly when doing valuation using DCF analysis to compute the present value of future cash flow of each period or year.
Simply put, it is a conversion factor when computing the time value of money. It is a weighting factor (or a decimal number) that is multiplied by the future cash flow to discount it to the present value. The term “discount factor” in financial modeling is most commonly used to compute the present value of future cash flows values.
