However, this upgrade will save the company an estimated $150,000 in electrical costs each year for the next 10 years. To do so will cost the company $800,000 this year. Middleton Manufacturing is considering installing solar panels to heat water and provide lighting throughout its plant. Excel simplifies the creation of an NPV profile. Especially if markets are volatile, a company may use an NPV profile to see how sensitive their decisions are to changes in financing costs. Also, the cost of attracting capital can change with economic and market conditions. Note: Because of the nonstandard use of the term NPV by Excel, many users prefer to use the method described above rather than this predefined function.įigure 16.8 Final Spreadsheet ($ except IRR/Cost of Funds) Using Excel to Create an NPV Profileįirms often do not know exactly what their cost of attracting capital is, so they must use estimates in their decision-making. Then, subtract the initial investment of year 0 to calculate NPV according to the standard definition of NPV-the present values of the cash inflows minus the present value of the cash outflow. When entering the Excel-programmed NPV function, you must remember to include references only to the cells that contain cash flows from year 1 to the end of the project. You must subtract the initial cash outflow of $30,000 that occurs at time 0 to get the NPV of $26,947 for the project. The NPV function in cell J6 will return $56,947 for this project. The Excel NPV function calculates the sum of the present values of the cash flows occurring from period 1 through the end of the project using the designated discount rate, but it fails to include the initial investment at time period zero at the beginning of the project. However, it is important to pay attention to how Excel defines NPV. The NPV formula is shown in cell J7 in Figure 16.6 below. One approach to calculating NPV is to use the formula for discounting future cash flows, as is shown in row 6.įigure 16.5 NPV Calculated by Summing Present Values of Cash Flows ($ except Cost of Funds)Īlternatively, Excel is programmed with financial functions, including a calculation for NPV. To calculate NPV using Excel, you would begin by placing each year’s expected cash flows in a sheet, as in row 5 in Figure 16.4. Your company would like to evaluate this project. You know that your company’s cost of funds is 9%. The cash inflow is expected to increase by $2,000 yearly, resulting in a cash inflow of $18,000 in year 7, the final year of the project. The cash inflow from this project is expected to be $6,000 next year and $8,000 the following year. Suppose your company is considering a project that will cost $30,000 this year. We will consider a couple of straightforward examples of using Excel to calculate NPV and IRR. Excel is a versatile tool with more than one way to set up most problems. An advantage of using Excel is that you can quickly change any assumptions or numbers in your problem and recalculate NPV or IRR based on that updated information. By the end of this section, you will be able to:Ī Microsoft Excel spreadsheet provides an alternative to using a financial calculator to automate the arithmetic necessary to calculate NPV and IRR.
