Because you provide the dates for each cash flow, the values do not have to occur at regular intervals.

As a worksheet function, the XIRR function can be entered as part of a formula in a cell of a worksheet.

If this parameter is omitted, it assumes an estimatedirr of 0.1 or 10.

The cash flow values are found in the range A4:A8 with the corresponding dates in B4:B8.

You then have the following income: 3,000 on 212016, 5,000 on 4152016, 1,200 on 812016 and 4,000 on 3262017.

You then have the following income: 800 on 5312016, 1,300 on 912016, 600 on 12312016 and 7,500 on 1312017.

Irr Excel Formula Series Of Inflowsoutflows

The Numbers IRR function calculates a per-interval return rate given an irregular series of inflowsoutflows at fixed intervals.

In the first row of this column, enter the date as Start: and for the amount, the starting account value, as a positive number.

In the second row, enter the date 11year for the year of interest.

Select it and pull down from the circle at lower right to create a date entry for each and every day, through 1231year.

Where Cash Flow Summary is the name of the table listing the cash flows.

Select this cell and drag it down to copy this over the rest of the days in the year.

This will select any cash flow amounts from the Cash Flow Summary table above on the given date.

So, if there were no investments or withdrawals to the account on that day, this cell will contain the negative final account balance.

You might consider referencing the initial and final account values from another, more convenient location.

Where Guess is an (annualized) initial guess for the return rate (like.05, or 5), and Days in Year is the number of days in the year (365 or 366 for leap years).

Now you can add any number of days with inflowoutflow to the summary table and the return value is updated at once.

As a check, for most cash flow streams, the computed annualized return will lie between the two values.

Pretending the total net inflow occured at the end of the year, reducing the final account value.

I am curious to know how many of you have successfully replaced Excel with Numbers.

Id guess that would be the most difficult piece of Office to do without.

In my own experience, Numbers works well for any task for which a spreadsheet is the best tool.

Having said that, for anything much more complex than a checkbook register, I find that a more powerful tool, such as R, is far better suited than a spreadsheet.

For one of many possible examples, typing -32 (without quotes) into either Excel 2008 or Numbers 09 incorrectly returns 9, when the correct value is -9.
