Microsoft Excel 使用迭代技术来计算 IRR。 从猜测开始,IRR 会循环执行计算,直到结果在 0.00001% 内准确。 如果 IRR 在 20 次尝试后找不到有效的结果,则 #NUM! 错误值。 多数情况下,不必为 IRR 计算提供 guess 值。 如果省略 guess,则假定它为 0.1 (10%)。 如果IRR 提供 #NUM! 错误值,或者如
This article describes the formula syntax and usage of theIRRfunction in Microsoft Excel. Description Returns the internal rate of return for a series of cash flows represented by the numbers in values. These cash flows do not have to be even, as they would be for an annuity. However, the...

Excel’s IRR function is programmed to work through 20 iterations to find a value that is accurate to within 0.00001%. If it can’t find one, then it returns a #NUM error.1Also, ensure you have at least one negative value, that your other fields are formatted correctly, and tha...
function IRRCalc(CArray, guest) { inc = 0.000001; do { guest += inc; NPV = 0; for (var j=0; j < CArray.length; j++) { NPV += CArray[j] / Math.pow((1 + guest), j); } } while (NPV > 0); return guest * 100; ...
Luckily, technology has provided tools on our desktop to easily perform this analysis. Microsoft Excel provides the IRR function, which will solve for the rate of return for a series of periodic cashflows. The basic function takes two arguments: a range of cash flows, and an initial guess. ...
Using theIRR function in Excelmakes calculating the IRR easy. Excel does all the necessary work for you, arriving at the discount rate you are seeking to find. Enter Cash Flows: In an Excel spreadsheet, list all the cash flows associated with the investment or project. These cash flows can...
TheXIRR function in Excelis commonly used to calculate a return on a set of irregularly spaced cash flows. Instead of solving for an effective periodic rate like the IRR, the XIRR calculates aneffective annual ratethat sets the net present value equal to zero. ...
For example, you might use the GoalSeek function in Excel. Let's take an example of NPV calculation and try to find the value of discount rate (cell C15), so that NPV (cell C12) would equal to zero:Moreover, you might calculate IRR by using the Newton’s method, where the root ...
Excel was used to calculate the IRR of 13%, using the function, =IRR(). From a financial standpoint, the company should make the purchase because the IRR is both greater than the hurdle rate and the IRR for the alternative investment. ...
