This calculator will help you to determine the average annual rate of return on an investment having unequal cash flows that occur on a regular basis.

You can choose from Annual, Semi-Annual, Quarterly, or Monthly cash flow intervals, as well as set the date of the beginning time period.

Plus, once you choose the cash flow frequency, set the starting time period, and enter the number of periods, the calculator will create a cash flow entry form (spreadsheet) on the fly, filling in all subsequent time periods for you. Cool!

Finally, once you have entered all cash flows and clicked the "Calculator IRR" button, the calculator will even generate a printable report showing the future value of each entered cash flow.

In other words, unlike other online IRR calculators, this calculator won't leave you guessing as to the validity of the internal rate of return result.

Note that if you want to calculate the internal rate of return for an investment having non-periodic cash flows, please use the XIRR Calculator instead.
