How are Returns Calculated Using XIRR?

The Extended Internal Rate of Return (XIRR) is a widely-used metric for evaluating the performance of investments with irregular cash flows, such as mutual funds, stocks, and real estate.

XIRR determines the annualized rate of return needed to bring the net present value of all cash flows to zero, taking into account both the timing and size of each inflow and outflow.

Investors and financial professionals use XIRR to analyze past investment performance and to make informed decisions about future investments.

In this blog, we’ll explore the concept of XIRR and walk through the steps to calculate returns using this method. Let’s dive in!

What is the XIRR Function?

XIRR is a built-in function in spreadsheet applications like Microsoft Excel and Google Sheets. It calculates the Internal Rate of Return (IRR) for a series of cash flows occurring at irregular intervals.

By factoring in the dates and amounts of cash flows along with the initial investment, the function determines the discount rate that sets the net present value of all cash flows to zero.

Syntax for XIRR in Excel:

=XIRR(values, dates, [guess])

• Values: Represents the cash flow amounts, including the initial investment (negative value) and subsequent inflows or outflows. These should be listed in a cell range, e.g., A1:A5.

• Dates: Corresponds to the dates of each cash flow, in the same sequence as the values, e.g., B1:B5.

• Guess (optional): An estimated return rate. If omitted, Excel uses a default value of 10% (0.1).

Syntax for XIRR in Google Sheets:

=XIRR(values, dates, [guess])

Steps to Calculate Investment Returns Using XIRR

Follow these steps to compute returns with XIRR:

1. Collect Cash Flow Data: Record all investment cash flows, including dates and amounts for deposits, withdrawals, and dividends.

2. Organize the Data: Create a table with two columns—one for dates and one for corresponding cash flows.

3. Enter Data in a Spreadsheet: Input the cash flow details into Excel or Google Sheets.

4. Select Output Cell: Choose the cell where you want the XIRR result to appear.

5. Use the XIRR Function: Enter =XIRR(values, dates, [guess]) in the selected cell.

6. Specify Ranges: Replace values with the cash flow range and dates with the corresponding date range.

7. Optional Guess Value: Provide an estimated rate if needed. Otherwise, the function assumes a default guess of 10%.

8. Calculate the XIRR: Press Enter. The function will return the annualized rate of return for the investment.

9. Analyze the Result: Review the percentage displayed, representing the annualized rate of return that balances the net present value of all cash flows to zero.

Did You Know?

The XIRR function was introduced in Microsoft Excel 4.0 in 1992 and has since become an essential financial tool. It’s now available in other spreadsheet programs like Google Sheets, OpenOffice Calc, and Apple Numbers.

Why Use XIRR?

XIRR offers a more accurate measure of investment performance than simple averages by accounting for the exact timing and size of each cash flow. This makes it particularly useful for analyzing investments with irregular cash flows, such as SIPs or real estate deals.

Conclusion

The XIRR function is a powerful tool for calculating the annualized rate of return for investments with non-uniform cash flows. By incorporating the timing and size of each transaction, XIRR provides a realistic picture of an investment’s actual performance.
