The general formula for this calculation, where "x" is the new price, is: x=old*(1-percentage)Ĭonverting this to an Excel formula with cell references, the formula in E5 becomes: =C5*(1-D5)Īs the formula is copied down, the formula returns a new price for each item in the table, based on the percentages shown in column D. For example, given an original price of $70.00, and an decrease of 10% ($7.00), the result should be $63.00. Some of the discount rates used by the majority of companies are WACC (weighted average cost of capital), cost of equity, cost of debt, risk-free rate of return or company-specific hurdle rate.In this example, the goal is to decrease the prices shown in column C by the percentages shown in column D. As such, the concept of discount rate is very vital in project valuation and so it is important that we choose an appropriate discount rate in order to arrive at the optimum valuation. The concept discount rate is predominantly used in the computation of NPV and IRR, which are a manifestation of the time value of money that states that a dollar today is worth more than a dollar in the future. Step 4: Finally, the formula for discount rate can be derived by dividing the future cash flow (step 1) by its present value (step 2) which is then raised to the reciprocal of the number of years (step 3) and the minus one as shown below.ĭiscount Rate = (Future Cash Flow / Present Value) 1/n – 1 Relevance and Uses of Discount Rate Formula Step 3: Next, determine the number of years between the time of the future cash flow and the present day. Step 2: Next, determine the present value of future cash flows. Step 1: Firstly, determine the value of the future cash flow under consideration. The formula for the discount rate can be derived by using the following steps: Therefore, the value of Steve’s lottery winnings today is $8,865. Calculate the present value of the lottery winnings if the effective discount rate is 5%. In this example, Steve has won a lottery worth $10,000 and as per the terms he will be receiving the winnings as yearly pay-out of $2,500 for the next 4 years. Let us now take an example with multiple future cash flow to illustrate the concept of a discount rate. Therefore, the effective discount rate for David in this case is 6.98%. Calculate the discount rate if the compounding is to be done half-yearly.ĭiscount Rate = T * In this example, David expects to receive a sum of $10,000 after 4 years and its present value has been assessed to be $7,600. Now, let us take another example to illustrate the impact of compounding on present value computation using the discount rate. Therefore, in this case the discount rate used for present value computation is 6.40%. Calculate the discount rate if the present value of the future cash flow today is assessed to be $2,200.ĭiscount Rate is calculated using the formula given belowĭiscount Rate = (Future Cash Flow / Present Value) 1/ n – 1 Let us take a simple example where a future cash flow of $3,000 is to be received after 5 years.
