How to Calculate Irr in Excel

The IRR function means Internal Rate of Return, and its main objective is to provide a solid and cogent result, which means it would return with a double value that would be specific of the IRR for a series of the periodic cash flows, as they have been inserted in the Microsoft Excel program.

IRR Parameters

There are different parameters for the IRR, and these contributes to its ability to provide a solid and concrete result, using the data it has been given by the user.

Values: This is critical for the function’s success, and therefore required. It is an array of the double that specifies the values of the cash flows. It is essential that the array has the minimum of one negative value, and one value that is positive. These positive values could be much more than one.

Guess: This is optional, but it does has a benefit to the IRR function, as it is the variant that would specify the value that has been estimated by the user that the IRR would be returning. If this has been omitted, then the guess would put it at 10%, which mean 0,1.
