![]() ![]() To calculate the internal rate of return after two years, you need to include a guess (in this example, -10%). Investment's internal rate of return after four years If you need to, you can adjust the column widths to see all the data. For formulas to show results, select them, press F2, and then press Enter. NPV(IRR(A2:A7),A2:A7) equals 1.79E-09 ExampleĬopy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. The following formula demonstrates how NPV and IRR are related: The rate of return calculated by IRR is the interest rate corresponding to a 0 (zero) net present value. IRR is closely related to NPV, the net present value function. If IRR gives the #NUM! error value, or if the result is not close to what you expected, try again with a different value for guess. The internal rate of return (IRR) also measures investment performance. If guess is omitted, it is assumed to be 0.1 (10 percent). The compound annual growth rate (CAGR) measures the return on an investment over a certain period of time. In most cases you do not need to provide guess for the IRR calculation. If IRR can't find a result that works after 20 tries, the #NUM! error value is returned. Starting with guess, IRR cycles through the calculation until the result is accurate within 0.00001 percent. Microsoft Excel uses an iterative technique for calculating IRR. A number that you guess is close to the result of IRR. ![]() If an array or reference argument contains text, logical values, or empty cells, those values are ignored. Be sure to enter your payment and income values in the sequence you want. IRR uses the order of values to interpret the order of cash flows. Values must contain at least one positive value and one negative value to calculate the internal rate of return. An array or a reference to cells that contain numbers for which you want to calculate the internal rate of return. The IRR function syntax has the following arguments: The internal rate of return is the interest rate received for an investment consisting of payments (negative values) and income (positive values) that occur at regular periods. However, the cash flows must occur at regular intervals, such as monthly or annually. ![]() These cash flows do not have to be even, as they would be for an annuity. Returns the internal rate of return for a series of cash flows represented by the numbers in values. This article describes the formula syntax and usage of the IRR function in Microsoft Excel. ![]()
