XIRR (CashFlowEvents,Dates,StartGuess,Accuracy,NoOfIterations)

• is the array of values.
• is the date value.
• is the starting number is close to the result of XIRR.
• is the accuracy value.
• is the number of iterations.
• XIRR(), returns the internal rate of return for a schedule of cash flows that is not necessarily periodic

## Description

• This function gives the internal rate of return for a series.
• In this function the cash flows that occur at uniform intervals which means that is not necessarily periodic.
• To calculate the internal rate of return for a series in a periodic time ,we can use the IRR function.
• is the when the periodicity between cash flows is not equal.
• function uses the iterative process to calculate the returns, so it is not possible to trial by hand.
• So this is most powerful function in CALCI.
• In , is an values which is the array or a reference to cells that contain numbers for which you want to calculate the internal rate of return.
• must have atleast one positive and one negative value to find the internal rate of return.
• Normally the first payment is optional,so the corresponding payment that occurs at the beginning of the investment.
• Then the first payment should be negative value.
• is the date value which is indicating the schedule of the payment.
• Also the first payment date is the beginning of the schedule of payments.
• And date should entered in DATE function format.
• is the guess which is indicating the number that you guess is close to the result of .
• is the accuracy value .
• is the number of iterations.
• suppose when we are omitting the value of ,by default it will consider as 10.
• The value of can be array or reference argument contains text, logical values or empty cells, the values which are ignored.
• The value is optional, when we are omitting the value,by default it will consider the value as 10%(0.1).
• This function is using iterative technique, so we can't find a result after 100 iterations.
• So the rate is changed until:
```    di=the ith, or last,payment date.
d1=the 0th payment date.
Pi=the ith or last payment.
```
• The rate of return calculated by is the interest rate corresponding to .
• This function will give the result as error when
```  1. Any date is not a valid date or not in a date function format.
2. Any date is precedes the starting date.
3. Also CashFlowEvents and Dates is having different number of values.
```
