Excel XIRR Function Returns Abnormally High Value: Tech Support
If you're trying to help a friend calculate the annual rate of return for their boss's brokerage account, and you're running into issues with the XIRR function returning abnormally high values, you're in the right place. In this article, we'll cover the key concepts related to the XIRR function in Excel, provide some subtitles to help break up the content, and include code blocks as needed.
What is the XIRR Function?
The XIRR function in Excel is used to calculate the internal rate of return (IRR) for a series of cash flows that occur at irregular intervals. The syntax for the function is as follows:
XIRR(values, dates, [guess])Where:
valuesis an array or range of cells that contain the cash flows, with positive values representing inflows and negative values representing outflows.datesis an array or range of cells that contain the corresponding dates for each cash flow.guessis an optional argument that specifies the initial guess for the IRR. If this argument is omitted, Excel will use a default value of 0.1 (10%).
Why is the XIRR Function Returning an Abnormally High Value?
There are a few reasons why the XIRR function might return an abnormally high value. Here are some things to check:
Make sure that the cash flows are in the correct order. The XIRR function calculates the IRR based on the order of the cash flows, so if they're not in the correct order, the result will be incorrect.
Check the dates associated with each cash flow. Make sure that they're accurate and in the correct order. If there are any gaps in the dates, the XIRR function might not be able to calculate the IRR correctly.
Check the initial guess for the IRR. If the guess is too far off from the actual IRR, the XIRR function might not be able to converge on the correct value. Try using a different guess to see if it makes a difference.
Check for negative cash flows that shouldn't be there. If there are any negative cash flows that shouldn't be there, they could be throwing off the calculation. Make sure that all of the cash flows are correct and that there are no errors in the data.
Example of Using the XIRR Function
Let's say that your friend's boss has the following cash flows and dates for their brokerage account:
| Date | Cash Flow |
|---|---|
| January 1, 2021 | -$10,000 |
| March 31, 2021 | $5,000 |
| June 30, 2021 | $7,000 |
| September 30, 2021 | $3,000 |
| December 31, 2021 | $12,000 |
To calculate the IRR for these cash flows using the XIRR function, you would enter the following formula:
=XIRR(B2:B6, A2:A6)Where:
B2:B6is the range of cells that contain the cash flows.A2:A6is the range of cells that contain the corresponding dates.
In this example, the XIRR function would return an IRR of approximately 0.17, or 17%.
